Interações comunicativas entre uma professora e um aluno com transtorno invasivo do desenvolvimento na escola regular

Inclusion of students with autism in regular education settings is a topic that has not been much explored by the national scientific literature. This matter is complex and, due to the extent of various aspects involved, it is essential to delimitate a focus of investigation. The direction taken by this study was to evaluate the effects of an intervention program in the communicative interactions between a student with autism and his teacher in a regular classroom. Data were collected in an elementary private school, located in the city of Natal, Rio Grande do Norte during the 2010 academic school year. The study included a teacher and a non-vocal, 10-year-old student diagnosed with autism. A quasi-experimental A-B research design was employed. During the intervention program the teacher was trained to use Naturalistic Teaching Strategies and Alternative and Augmentative Communication (AAC) resources to increase the frequency of interactions with the student during three classroom routines (entry time, snack and pedagogical activity). The results indicated qualitative and quantitative changes in the interactions of the dyad after the implementation of the intervention program. The student began to use pictograms to communicate with the teacher in two of the three routines investigated. The frequency of AAC use was also observed in the teacher‟s repertoire, especially when the student failed to understand gestures and words. The teacher positively evaluated the intervention program

Gêneros do discurso e escrita: o que as coleções didáticas de português (des)prestigiam no ensino da produção textual?

Through the examination of official indicators, it can be observed that writing is pointed out as one of the main problems concerning formal basic education. However, this teaching-learning object is one of the central objectives at school, having an essential role in different curricular components as well as in the interaction demands required by society. Such paradox indicates, therefore, the relevance of investigations which analyze the intrinsic elements of child development as written text producer. Hence, the main purpose of this research consists of analyzing the treatment given to the types of discourse and the teaching situations in which the written text are produced, concerning Portuguese language didactic material collections approved by Programa Nacional do Livro Didático (PNLD 2010) the Brazilian program of didactic book and worked at elementary school. Such materials correspond to the collections adopted in municipal education system schools from Natal, RN which were below the official education indicator IDEB 2009. Thus, the questions that guide this work are: 1. During writing production lessons, is the diversity of types of discourse effectively worked on didactic collections? 2. Which are the types of discourse and the social spheres prioritized when teaching writing production? 3. How is the situation addressed in the production of the written text should be produced? For this research, we retook the authors Bakhtin, Bunzen, Faraco, Freire, Rodrigues, Rojo, Schneuwly e Dolz and we made a list of all types of discourse and spheres contemplated in the propositions of the writing production in didactical books, concerning the eight collections which compounds the first moment of analysis. Then, we verified how the situation of production is oriented by examining two didactic collections if and how they express the elements referring to the social-historical, functional and linguistic-discursive context of the text to be produced. The data obtained indicate: lack of diversification of types of discourse in the collection that compounds the Aggregate Sample of the research; the conception of a diversity based on the didactic of visiting; the recognition of all canonical and hegemonic types of text as one of the privileged objects of study; the centralization on the standard variety of the language and the devaluation of the representative types of cultural diversity; the shortage of productions which retrace to written language related to different technologies of communication and information; and the little emphasis on the types of discourse related to public language practices. As for the situations of production, it is observed the predominance of the school as a producer of dialogic relationships, whose propositions present, for example, text addressees, enunciative positions, support and contexts of restricted circulation, especially at school. Two divergent situations are observed among the collections: the lack of a work in which the situation of production is under the perspective of the types of discourse as object of teaching-learning; the concept of the types of discourse as object of reflection, presenting a differentiated didactic orientation towards the situation of production. This research contributes, therefore, with a mapping of the existence and the treatment of the types of discourse on propositions of writing production in didactic books; with the critical analysis of the approach of written activities, considering the elements of the historical-social, functional and linguistic-discursive context; thus, through teaching, research and public policies, use and selection of didactic material for the area

Estudo representacional da participação familiar nas atividades dos centros de atenção psicossocial no município de Natal-RN

Comprehending social representations of users relatives of Psychosocial Care Centers (CAPS) from Natal-RN, about their participation in the activities of these services, was the purpose of this study. The research instrument used was a semi-structured interview, led to 28 relatives of users of East and West CAPS II, East and North CAPS-ad, involved in the Relative Therapeutic Group, in Relative Meeting, in the Assembly of Users, Technicians and Relatives, according to the therapeutic schedule of each health services, between August to November 2007. Data obtained in family and users identification were characterized with the aid of charts and boards in absolute and/or percentage values. The discursive material from the guide from interviews was submitted to the informational resource ALCESTE (Analyse Lexicale par Contexte d'un Ensemble of Segments of Texte), and analyzed on the basis of the Theory of Social Representations and Central Nucleus Theory. Most of the relatives were women, married, aged over 50 years, who participated for more than two years in CAPS activities, and a coexistence of more than 11 years with the user. From the classification system of ALCESTE were selected categories, identified by: Category 1, Treatment Improvements and Expectations; Category 2, Living User Before and After; Category 3, Activities Relevance, Contradictions and Suggestions; Category 4, Guidelines -- Psychopharmacology and Medicalization; Category 5, Family Participation and Activities; and Category 6, Therapeutic Conditions Thanks, Tips and Vulnerability. The social representation of the family exists in the desire for change, identifying that we need to promote change by the continuity of therapeutic activities and overcome the detected inconsistencies, targeted by strengthening and by the stability of improvements in living and health conditions of users, experienced in CAPS treatment. The central nucleus had corresponded to positive changes in health and living conditions of users, and the peripheral elements were constituted by family conducts before and during treatment, and the expectations of changes in activities, especially in workshops. Despite this family participation be considered important, it still does not meet conditions to promote the inclusion of family, under an emancipating point of view, capable of causing in subject the hope for autonomy, initiative, individual and collective growths, a closer and active involvement in therapeutic activities, in workshops and discussions

Desempenho de híbridos de milho submetidos a diferentes espaçamentos e densidades populacionais

O objetivo deste trabalho foi avaliar a influência de espaçamentos entre linhas e densidades populacionais, nos componentes de produção e na produtividade de grãos, em dois híbridos de milho (Zea mays). O experimento foi conduzido na safra 2006/2007, em Latossolo Vermelho eutrófico típico, textura argilosa, em Jaboticabal, SP. O delineamento experimental de blocos ao acaso foi composto por 24 tratamentos com parcelas subsubdivididas. As parcelas principais foram constituídas por três espaçamentos entre linhas (0,40, 0,60 e 0,80 m), as subparcelas, por dois híbridos e as subsubparcelas, por quatro densidades populacionais (30 mil, 50 mil, 70 mil e 90 mil plantas por hectare). Foram avaliadas as variáveis: altura de planta e altura da inserção da primeira espiga, diâmetro de colmo, número de grãos por espiga, massa de 1.000 grãos, produtividade de grãos e índice de colheita. A produtividade do milho aumentou com a redução do espaçamento entrelinhas para os híbridos avaliados. O incremento na densidade populacional de milho resultou em aumentos na altura das plantas e na altura da inserção da primeira espiga e em redução do número de grãos por espiga. O melhor arranjo de plantas para os híbridos avaliados é de 0,40 m de espaçamento entre linhas e de 75 mil e 80 mil plantas por hectare de densidade populacional.

Qualidade de vida de pessoas com úlceras venosas atendidos no ambulatório de um hospital universitário

Descriptive study aimed to analyze the quality of life (QOL) of patients with venous ulcers (UV) outpatient clinic of a university hospital in Natal / RN. The aim of the study population was composed of 50 patients with UV treated at the cardiology clinic of a university teaching hospital at the tertiary level. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (Protocol 279/09). Data collection was performed over a period of two months by the very a masters degree and an academic nursing through the application of a form concerning the socio-demographic, clinical, and health care, and the instruments WHOQOL and WHOQOL - old. The data were analyzed with SPSS 15.0, using descriptive and inferential statistics presented in the form of tables, charts and graphs. Of the surveyed, female predominance, age range 59 years, Catholic, low education, married, with up to 03 children, not working, retired, or with occupations requiring long periods in one position, wage income of up to 02 minimum wages, inadequate sleep, patients with chronic venous insufficiency and other chronic diseases such as diabetes and hypertension, were taking medications for treatment, being a minority to IVC. In patients with predominant only one injury, time of injury up to five years, inadequate rest, pain, edema and lesions colonized. The assistance the UV patients began treatment of the injury until four months after the onset of the ulcer, and services primary health care most wanted, access to angiologist by reference form, commuted by public transportation, received support regarding the treatment of injuries. The topical product most used in the lesion was healing, and few were using compression therapy. respondents suffer discrimination in society, showed changes in quality of life after the occurrence of ulcer in relation to leisure, pain, restriction of social / school / transportation; barring employment / financial / social ladder; Physical appearance / discrimination and restriction of domestic activity. These changes were related to the time of injury and found that the more chronic injury is the most negative changes occur in their QV (ρ = 0.000). Analyzing the characteristics of QV measured by the WHOQOL-bref, we found for the two general questions they are dissatisfied with their health (ρ = 0.023) and all areas have significant difference compared with the worst QV have the injury of more than 5 years (ρ = 0.000). The QV measured by the WHOQOL-old, we found that these patients had no changes from the time of injury. We conclude that the QV of patients with UV was considered unsatisfactory when compared to the time of injury on more than 5 years which shows that the quality of life worsens with time the chronic UV.

Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope

Trânsito de saberes e campo representacional na visão dos profissionais da saúde da família e do programa de educação pelo trabalho e para a saúde

The Family Health Strategy (ESF) is emerging as a possible restructuring of services and new practices of intervention in health care; it requires skilled professionals to work with that framework. Within this purpose, we established the Education Programme for Work and Health (PET-Saúde), in order to integrate teaching and service activities, focusing on primary care. On this basis, the aim of this work is to apprehend the social representation of nurse, doctor and dentist (Project PET-Natal Health RN preceptors) on the ESF, while practice field of them. It is a descriptive and exploratory study, with a qualitative approach, carried out in 07 Family Health Units (USF) included in the PET-Saúde Natal (RN). The population was composed of 35 professional components of the primary care team with bachelor's degree of the USF linked to this project. The sample was composed of 05 nurses, 05 physicians and 05 dentists, for a total of 15 subjects. Data were collected through three instruments: the drawing-themed story, a semi-structured individual interviews and field diary. The data relating to the identification of the subjects were entered and tabulated by the Microsoft Excel software 2007 version. The drawing analysis and interpretation is given by the significance attributed to the resource chart from title and keywords assigned by the subjects, considering the ESF as an inductive term. The stories and interviews were transcribed and typed and then subjected to read/listen the material and a lexical analysis through Alceste. After this process, the discursive material was analyzed and discussed by theoretical and methodological feature of the Social Representations theory. The majority of health professionals were female, aged between 46 and 52 years old, married, income less than six minimum wage, time since graduation ranged from 22 to 29 years and working time in the ESF range from 02 to 11 years. From the classification system ALCESTE were selected categories identified by: Category 1 - ESF: relations and territory; Category 2 - Training and bond profile; Category 3 - Working process in the ESF; Category 4 - Articulation between teaching and service; Category 5 - Health care and disease prevention. The representational field construction, while a process, followed the logic of structural cores in existing categories. In this sense, it is clear that the ESF is an environment rich in diversity, experience and relationships with potential such as the relationship "very subject-subject" and the link established between professional-community, but also has some weaknesses such as poor working conditions, lack of popular participation and management support, thus difficulties in the achievement of teamwork. Being essential to that end, the teaching-service aimed at the formation of a new health professional able to work in the ESF. In this research, the training of the representational field encountered a diversity of structural cores, or thoughts on training, about the ESF because of the greater emphasis on the here and now of the interaction between health professionals, the ESF, the community, PET Health-UFRN and students, emphasizing that such proposals are still considered as concepts in the context of recent health and that, therefore, are not fully realized in the social imaginary

A palavra cantada nos espaços intersubjetivos de um centro de atenção psisossocial do município do Natal/RN

The psychiatric care and mental health are undergoing constant change over the History. The Brazilian Psychiatric Reform, which brings up the deinstitutionalization as a structuring in the restorative care process. The Reform has as one of the mainly substitutive services the Centers for Psychosocial Care (CAPS), which work from the Singular Therapeutic Project (PTS) in order to restore the autonomy and restore the dignity of users. The therapeutic workshop is some of the resources used and work several kinds of activities as: writing, handcraft, music, poetry, and so forth. This study set up to apprehend the social representations of helping of the music workshop carried out in the CAPS II east of Natal/RN, from the reports given by the participants of the workshop, using the focal group as technique. This is a descriptive exploratory study with a qualitative approach. A total of 16 users participated in four musical therapeutic workshops from April to May 2010. The study was approved by the Ethics and Research Committee of UFRN. The discursive material from the workshop was submitted to the informational resource of Analyse Lexicale par Contexte d um Ensemble de Segments de Texte, ALCESTE, and analyzed based on the Theory of Representations and the Central Core Theory. The majority of subjects were men (62.5%), single (62.5%), aged 40-49 years (37.6%) and elementary school level (56.2 %). The reports were transcribed and submitted to the classification system of ALCESTE, which elected the following categories: Category 1 - Experience in the Word Family Sung, Category 2 - Musical Experiences and Approaches, and Category 3 - Feelings and emotions evoked by music. The representation of these individuals is anchored in the experience they have with the CAPS, lived and socialized by common sense, through this particular social group workshop objectified in music therapy as a therapeutic modality enjoyable. The central core revealed the intrinsic relationship between users and the music, establishing a relationship of openness to use the same while its therapeutic use in workshops of substitute services for mental health. Peripherals elements issues are related to listen, share and experience music in the family. Intermediary Elements relate to the feelings and emotions evoked by music, given her close relationship with it. It was found in the study that music can be construed as an artifact of good therapeutic responsiveness to users, configuring it as an invigorating and enjoyable therapy, confirming the need for continuity of this activity, as well as its expansion into the service

ALTERAÇÕES em ALGUNS ATRIBUTOS QUÍMICOS do SOLO DECORRENTES da IRRIGAÇÃO E ADUBAÇÃO NITROGENADA E POTÁSSICA em BANANEIRA APÓS DOIS CICLOS DE CULTIVO

Superfícies geomórficas e atributos de Latossolos em uma seqüência Arenítico-Basáltica da região de Jaboticabal (SP)

Em um segmento de vertente com substrato de arenito em contato com basalto, regionalmente muito freqüente, pretendeu-se não só relacionar as superfícies geomórficas com os atributos físicos, químicos e mineralógicos dos Latossolos nelas encontrados, mas também testar métodos geoestatísticos para localização de limites dessas superfícies. Usando critérios geomorfológicos, três superfícies foram identificadas e topograficamente caracterizadas. Os solos foram amostrados, a intervalos regulares de 25 m, na profundidade de 0,6 a 0,8 m (topo do horizonte B), em uma transeção de 1.700 m perfazendo 109 pontos. Nas amostras, foram analisados: densidade de partículas, granulometria, CTC do solo, CTC da argila, Fe total da argila (ataque por H2SO4) e óxidos de Fe livres (por dissolução seletiva). A fração argila desferrificada foi analisada por difração de raios X. Com base na estratigrafia e variações do relevo local, foram identificadas e diferenciadas, no campo, três superfícies geomórficas. Analisaram-se também o perfil altimétrico e o modelo de elevação digital do terreno. Observou-se que as três diferentes superfícies estão bem relacionadas com os atributos físicos, químicos e mineralógicos dos seus respectivos solos. Na parte inferior desta vertente, superfície mais recente e sobre basalto, em Latossolo Vermelho eutroférrico típico, foram encontradas as maiores variabilidades da declividade, da argila e de Fe. As variações da inclinação do terreno, quando analisadas sistematicamente pelo split moving windows dissimilarity analysis (análise estatística de dissimilaridade, em segmentos móveis), mostraram que este método estatístico pode ser usado para ajudar a localizar os limites entre superfícies geomórficas. As variações dos solos da transeção, e arredores, mostraram-se relacionadas com idade, inclinação do terreno e litologia. O trabalho geomórfico detalhado forneceu importantes informações para subsidiar os trabalhos de levantamento de solos e de pedogênese.

Adubação nitrogenada na cultura do milho

Efeitos da subsolagem e da adubação verde nas propriedades físicas do solo em pomar de citros

O presente trabalho teve por objetivo avaliar o efeito da subsolagem e da adubação verde nas propriedades físicas de um Latossolo Vermelho distrófico típico, cultivado com citros (laranjeira Valência). Os tratamentos empregados foram: manejo mecânico das plantas invasoras com roçadora (Testemunha); subsolagem em um lado da planta na entrecopa; subsolagem nos dois lados da planta na entrecopa, e semeadura direta de Crotalaria spectabilis na entrecopa. As propriedades físicas do solo avaliadas foram: porosidade total, macroporosidade, microporosidade, densidade, resistência mecânica à penetração vertical e condutividade hidráulica. Na avaliação efetuada na safra 2001-2002, obtiveram-se os maiores valores de densidade do solo e resistência do solo à penetração vertical, e os menores valores de macroporos e condutividade hidráulica do solo nas entrecopas com e sem tráfego no pomar, em relação à região da copa, principalmente na camada de 0,0-0,2 m de profundidade. Os tratamentos aplicados não surtiram efeitos positivos significativos nas propriedades físicas do solo.

Efeito prolongado de sistemas de preparo do solo com e sem cultivo de soqueira de cana crua em algumas propriedades físicas do solo

Este trabalho foi conduzido em Latossolo Vermelho distrófico típico, sob cultivo de cana crua, com o objetivo de avaliar o efeito prolongado de sistemas de preparo do solo, com e sem cultivo da soqueira, e épocas de amostragem sobre algumas propriedades físicas do solo. O delineamento experimental foi o de blocos ao acaso, em esquema de parcelas subsubdivididas, sendo os tratamentos principais quatro sistemas de preparo do solo: (i) controle da soqueira com duas gradagens, subsolagem e mais uma gradagem de nivelamento; (ii) controle da soqueira com herbicida e uma subsolagem; (iii) controle da soqueira com herbicida; (iv) controle da soqueira com herbicida, aração com arado de aivecas e uma gradagem de nivelamento. Os tratamentos secundários foram: com cultivo e sem cultivo da soqueira. Os tratamentos ternários foram as épocas de avaliação: dois dias antes e após a quarta colheita da cultura. A porosidade total, macroporosidade, microporosidade e densidade do solo foram avaliadas, além do perfilhamento e da produtividade da cultura. Após quatro sucessivas colheitas de cana crua, houve redução da macroporosidade com aumento da microporosidade nas camadas abaixo de 10 cm e aumento da densidade do solo entre 20 e 50 cm. A densidade do solo não foi alterada de modo consistente em função de todos os tratamentos testados. O cultivo da soqueira favoreceu o aumento da macroporosidade com decréscimo na microporosidade, e o efeito inverso foi observado após a colheita. Os sistemas de preparo do solo e de cultivo da soqueira não afetaram o perfilhamento e a produtividade da cultura.

Agregação de um argissolo sob pomar de goiabeiras após aplicação de resíduos da indústria processadora de goiaba

A utilização de resíduos da indústria de processamento de frutas na agricultura pode proporcionar melhorias à qualidade do solo. Dessa forma, objetivou-se com este estudo avaliar o efeito da aplicação de resíduos de sementes de goiaba na agregação e no estoque de carbono orgânico do solo (EC). O experimento esteve inserido em um pomar comercial irrigado de goiabeiras (cv. Paluma), com sete anos de idade, sobre um Argissolo Vermelho-Amarelo distrófico típico. O delineamento experimental foi em blocos casualizados e parcelas subdivididas, sendo cinco tratamentos (doses de: 0;9;18;27 e 36 Mg ha-1 de resíduo) e duas camadas de solo (0-0,10 e 0,10-0,20 m). Foi avaliado o mesmo tipo de solo sobre mata nativa adjacente à área experimental. As análises realizadas foram a distribuição do tamanho dos agregados estáveis em água, o diâmetro médio ponderado, o diâmetro médio geométrico, os agregados maiores que 2 mm e o EC. Os dados foram submetidos à análise de variância (Teste F), seguindo o delineamento em blocos casualizados com parcelas subdivididas (5 doses x 2 camadas). As médias dos tratamentos foram comparadas pelo teste de Tukey, a 5% de probabilidade, e as médias das camadas foram comparadas pelo teste F, a 5% de probabilidade. Os dados coletados no solo sob mata foram utilizados apenas como referência de um solo em estado natural e, portanto, não foram considerados como fator de variação nas análises de variância. Os valores dos índices de agregação com o estoque de carbono orgânico do solo foram submetidos à correlação de Pearson (p < 0,05). O efeito das doses de resíduo de sementes de goiaba sobre o estoque de carbono orgânico, na camada de 0-0,20 m do solo, foi avaliado por análise de regressão. Os tratamentos não diferiram em relação à agregação do solo, contudo EC foi diretamente relacionado à quantidade de resíduo aplicado ao solo. Houve correlação positiva e significativa entre os índices de agregação e o EC. A aplicação de resíduos de sementes de goiaba proporcionou melhoria da qualidade do solo.

Atributos do solo sob pastagens em sistema de sequeiro e irrigado

A pecuária é uma das atividades econômicas mais importantes da região do cerrado, sendo que o sucesso dessa atividade é dependente do sistema de manejo e de gramíneas forrageiras adaptadas às condições edafoclimáticas da região. Objetivou-se, neste tabalho, avaliar os atributos do solo em áreas sob pastagens com capim-Tanzânia (Panicum maximum Jacq. cv. Tanzânia) e braquiarão [Brachiaria brizantha (Hochst ex A. Rich.) Stapf. cv. Marandu], em sistema de sequeiro e irrigado no município de Rio Verde, GO. O experimento foi instalado no Centro Tecnológico Comigo, em um Latossolo Vermelho-Amarelo Distrófico típico, em 16 parcelas com 450m² cada. Adotou-se o delineamento em blocos completamente casualisados, referindo-se aos quatro tratamentos: capim-Tanzânia e braquiarão com e sem irrigação, com quatro repetições. Foram realizadas análises de atributos físicos (estabilidade de agregados) e químicas (pH, cálcio, magnésio, potássio, fósforo, acidez potencial, capacidade de troca catiônica, saturação por bases e conteúdo de matéria orgânica). Os atributos químicos variaram em ambas as profundidades, decorrentes principalmente da ação da calagem e adubação do solo independente da ausência ou presença de irrigação. Os tratamentos com capim-Tanzânia e braquiarão sem irrigação apresentaram os maiores teores de matéria orgânica e tiveram os maiores valores do diâmetro médio geométrico (DMG). A maior porcentagem dos agregados ficou retida na peneira de > 2,0mm de malha. A irrigação não afetou a produção de massa seca do capim-Tanzânia e braquiarão.
