Avaliação das áreas de conflito de uso em APP da microbacia do alto água fria, Bofete (SP)

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.

Geoprocessamento de variáveis morfométricas para caracterização da microbacia do Córrego do Petiço

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

Impactos da legislação na pesquisa etnobotânica no Brasil, com ênfase na região amazônica

The Amazon region has a large sociobiodiversity, where lives people with traditional knowledge about the uses of its natural resources. The Convention on Biological Diversity (CBD) in 1992 recognized the autonomy of each nation over its genetic resources and the rights of traditional populations about the knowledge of the use of these natural resources. In 2001 it was published the law M.P. 2.186-16/2001 which created the Conselho Nacional de Gestão do Patrimônio Genético (CGEN) and the first rules about access to genetic resources and associated traditional knowledge in Brazil. Since his creation, the actions of CGEN have received criticism from various sectors, both private and public, and, unlike its initial proposal, has become one of the main obstacles of ethnobotanical studies, the bureaucracy, the long process analysis and communication difficulties with this organ.

Lâminas de fertirrigação e substratos na produção e qualidade de gérbera de vaso

Fertigation management of gerbera crop has been many times performed inadequately, and it has been worsened when mixtures of substrates with different physical and chemical characteristics are used. Aiming at evaluating the production and quality of potted gerbera in two substrates and different levels of fertigation, the experiment was conducted in the greenhouse of the DRN/Soil Science, FCA/UNESP, Botucatu (SP). A 5 x 2 factorial randomized block design (5 levels of fertigation and 2 substrates) was adopted with 4 replications. Levels of fertigation corresponded to maintenance of 100% available water (AW) in the substrate; 100 to 80% of AW; 100 to 60% of AW; 100 to 40% of AW and 100 to 20% of AW. The substrates were as follows: 1- mixed coconut fiber (50% pellet coconut fiber and 50% coir fiber), 2- 40% red soil, 40% decomposed pine bark, 10% composition 1 (40% decomposed pine bark, 30% vermiculite and 30% carbonized rice husk) and 10% composition 2 (75% decomposed pine bark and 25% needles of pine). Plants at the marketing stage were evaluated according to the number of leaves; diameter of leaf surface; leaf area; fresh and dry phytomass of leaves, inflorescence and total plant; inflorescence number and diameter, stem diameter, plant height, leaf area rate and electrical conductivity of the substrate solution. Plants of better quality were obtained when they were maintained in levels of 100% available water and the mixed coconut fiber was used as substrate.

Uso de estimulantes de crescimento radicular associado a doses de fósforo na cultura do feijoeiro

O trabalho teve como objetivo avaliar o efeito da aplicação do Stimulate e Forth Seed associados a cinco doses de fósforo(P) no desenvolvimento do sistema radicular e parte aérea de plantas de feijão. O experimento foi desenvolvido em condições de casa de vegetação nas dependências do Departamento de Recursos Naturais – Ciência do Solo, da Faculdade de Ciências Agronômicas (FCA), UNESP, Campus de Botucatu, SP. O solo usado foi um Latossolo Vermelho Escuro de textura média. As unidades experimentais foram vasos contendo 8 dm3 de solo mantendo-se a umidade correspondente a 60% do Volume Total de Poros (VTP) ocupados por água. Utilizou-se a cultivar de feijão IAC-Carioca, em um delineamento experimental inteiramente casualizado, sendo os tratamentos constituídos de dois produtos (Stimulate e Forth Seed) nas respectivas doses 5 e 3 mL Kg-1 de sementes e uma testemunha sem biofertilizante, e 5 doses de P (0, 16, 32, 64 e 128 mg dm-3), com três repetições. Foi avaliada, também, a qualidade fisiológica das sementes usadas no experimento por meio de: a) primeira contagem do teste padrão de germinação; b) emergência; c) vigor, mediante a contagem de emergência; d) velocidade de emergência e determinação do crescimento das plântulas. O uso de Stimulate e Forth Seed agregados a doses de P causou redução no peso seco final das plantas.

Eficiência agronômica da aplicação foliar de nutrientes na cultura da soja

The need to increase soybean production has led many producers to seek alternatives, one of them is the use of foliar fertilization. The aim of this study was to evaluate the agronomic effectiveness of different doses of foliar applications of Mg, Zn and B in soybean. The experiment was installed in the area of the Department of Natural Resources/Area of Soil Science, Faculty of Agronomic Sciences, UNESP, Botucatu, São Paulo, Brazil, in an Oxisol. The design was completely randomized design with eight treatments and foliar applications of ten repetitions, for a total of eighty vessels. It was observed that the treatment (17% B +20% Zn) had a higher efficiency in fresh weight, dry weight and height of soybean, as compared to the productive treatment (17% B + 10% Mg) was what gave the best performance among the treatments.

Adequação territorial com abordagem multicriterial pela análise da combinação linear ponderada

From the characterization of biophysical attributes of the watershed (slope, soil types, capacity to land use and land cover), this article, used the multi-criteria analysis method – Weighted Linear Combination, defined priority areas for adaptation to the use of land as to its capacity of use. With this methodological approach, were created for the watershed under study, four classes, formed by different combinations of biophysical attributes (discrete data), representing levels of priorities for agricultural land use. The Multicriteria Evaluation in a GIS is suitable for the mapping of priority areas to the suitability of land use in watersheds. The geospatial information on the biophysical environment, generated from the methodological procedures described in this article, has a high positive potential to guide the rational planning of the use of natural resources and territorial occupation, besides serving as a powerful instrument to guide policies and collective processes of decision on the use and land cover.
