Espacialização do banco de sementes de plantas daninhas sob diferentes manejos de cana-de-açúcar em Rio Brilhante, Mato Grosso do Sul

The State of Mato Grosso do Sul is in full growth of this sector, thus the concern about harvesting systems are being studied, and these systems may influence the weed community interference of weeds in the cane sugar. The integrated management tool attached to geostatistics is to avoid productivity losses due to weed interference. The objective of this work was to study the spatial variability of the seed bank of weeds depending on the system for collecting cane sugar (raw and burning). The experiment was conducted in the area of commercial cultivation of the plant ETH Bioenergy S/A Eldorado Unity. Soil samples were taken with auger layer from 0.00 to 0.40 m depth in both cropping systems. The experimental plot was composed by a mesh consisting of 50 points georeferenced with irregular distances. Soil samples were taken to the greenhouse for germination. The number of weed species was analyzed using descriptive statistics and geostatistical techniques. The seeds of B. pilosa, dicots, bitter grass, nutsedge, dayflower monocots and spatial dependence of the seed bank in the collection system with burning of cane sugar. For the system of harvest only the raw sedge species present spatial dependence of distribution in the seed bank. In the harvest green cane enable the mapping of these species through the kriging maps produced, spot applications of herbicides in integrated management of Cyperus rotundus.

Leaching potential and residual effect of amicarbazone in soils of contrasting texture

The infestation of weeds is a major biotic factor in the agroecosystem of cane sugar that may interfere in development and crop productivity. This study aimed to evaluate the potential for leaching and residual effects of the herbicide amicarbazone in contrasting soils. Samples were Quartzarenic Neosol (NR - sandy texture) and Red Latosol (LR - clay texture). For the leaching potential, after application of herbicide amicarbazone (NR 1.05 kg ha(-1) and LR 1.40 kg ha(-1)), layers of 0, 20, 40, 60, 80 and 100 mm of water were applied to soil columns. We evaluated the residual effect after the permanence of the herbicide in soil of clay texture and sandy for periods of 0, 25, 50, 75 and 100 days after application (DAA) of amicarbazone (0, 1.05, 1.40 kg ha(-1)) treatments. The amicarbazone started showing high leaching from the 60 mm layer of water in sandy texture soils, evidencing a shorter residual effect. In clay soil, slides from 20 to 80 mm of water reduced the biomass until a depth of 5-10 cm, with the use of this herbicide. Based on these results, we conclude that the amicarbazone showed higher leaching and lower residual effects in sandy soil. The residual effect of amicarbazone was prolonged as the content of clay and organic matter present in the soil increased.

Identificação de patógenos e qualidade higiênico-sanitária do caldo de cana (garapa), consumido no interior do estado de São Paulo

The state of São Paulo is the largest producer of cane sugar in Brazil, with approximately 346 million tons in 2008/2009. This great production, associated with hot weather favors trade in sugar cane juice in most cities in the state. Contamination by parasites usually occurs during production but the contamination by bacteria is related with foodhandlers, equipment (grinders) and utensils used in the extraction. Due the lack of data in Botucatu and region, the objective of this study was to analyze 50 samples of syrup, according to the microbiological requirements of RDC Nº 12 (determination of Most Probable Number of thermotolerant coliform and the presence of Salmonella sp) as well the presence of Staphylococcus aureus and Trypanosoma cruzi. Salmonella sp., Staphylococcus aureus and Trypanosoma cruzi were not found, however 82% of the samples presented a higher contamination by thermotolerant coliform than that allowed by microbiological parameters, demonstrating inadequate conditions for retail, besides the lack of hygienic instructions of the sellers

Sensoriamento remoto e Sistemas de Informações Geográficas (SIG) na análise dos impactos referentes à cultura canavieira e reflorestamento: a subtração dos biomas nativos no município de Itirapina-SP

The main objective of this study was to perform a temporal analysis of land use and cover of Itirapina – São Paulo estate, Brazil, for 1962, 2000 and 2008 scenarios, indicating the rate of change in native vegetation and contextualizing its modifications. Based on photointerpretation performed by supervised classification using the method of Bhattacharya, the thematic classes were mapped and characterized in an area equivalent to 56400 hectares. Using remote sensing technologies and geographic information systems, was structured and implemented a georeferenced and relational database, allowing the analysis of the size of the area occupied. The results showed that the expansion of cultivation of cane sugar and reforestation in the past 45 years has been conditioned the fragmentation of natural vegetation cover in the city, which fell by 34793 ha (61,7%) in 1962 to 9765,2 ha (17,3%) in 2008, with the loss of 25027,8 hectares.

Consumo e incorporação de água na produção de commodities brasileiras

Water is one of the main inputs in agribusiness and is traded indirectly through the sale of agricultural products such as orange (juice or fresh) and cane sugar (ethanol and refined sugar). This study aims to estimate the proportional mass of water present in the products exported in the form of agricultural commodities considering the amount of water incorporated into the product in its genesis by plant photosynthesis, reinforcing a reflection on virtual and real water export, as well to indicate subsidies to management, planning and taxing of water resources

Diagnóstico ambiental do município de Ipeúna: subsídios para o planejamento do turismo

This study sought to address the tourism system in its various strands, compared to socioeconomic and environmental issues. Contextualizing the theme of sustainable tourism, or ecotourism, the reality of the city of Ipeúna, there is the incipient state of efforts in this activity because, predominantly, its territory is occupied by the monoculture of cane sugar and pastures, which damages the maintenance of vegetation fragments, as well as degrading areas that often could take a value tour. Through environmental planning, was intended to raise major issues of interface tourism / environment in order to seek alternatives to the implementation and development of tourism in Ipeúna. As a result, it presents an environmental diagnosis of the study area through which to assess the current status of tourist attractions in relation to environmental and socio-economic dynamics of the city.

A territorialização do setor sucroalcooleiro no Pontal do Paranapanema: estudo de caso do município de Martinópolis - SP

The sugarcane agribusiness has expanded by Brazil in recent years, especially with government incentives, which funded the construction and expansion of distilleries and sugar mills and alcohol throughout the national territory, as well as the expansion of the cultivation of sugarcane sugar. The state of São Paulo is the main focus of expansion in the sector, and its municipalities impacted significantly. The Pontal do Paranapanema is one of the last frontiers of cane sugar in the state, so that the culture has brought transformations mainly from 2003. Thus, we take the case of the municipality of Martinópolis analysis, which investigated some transformations in economic dynamics from 2004, the year he began the deployment of Plant Athena. For this, we conducted interviews with several subjects and analyzed statistical data from IBGE, LUPA, MAPA and CANASAT. Aware that these changes are limited to the capitalist market economy, we analyze the benefits and disadvantages brought by the activity of the plant for the population as part of economic growth characteristic of this scenario, taking it to the very prospect of local subjects. Alongside this growth, all other forms of inequality and exploitation of surplus value also grow which is not understood or perceived by residents. Hence the need to confront views and discourses on development promoted by the alcohol sector

Análise das emissões de gases do efeito estufa na produção do milho através da fertilização por resíduos de biocombustível. Estudo de caso : Dedelow - Brandemburgo - Alemanha

The focus of this research study were gas exchange between soil and atmosphere of nitrous oxide (N2O) between different fertilization treatments Corn The research, conducted in the experimental field Dedelow - Brandenburg / Germany, analyzed three different fertilization treatments, aiming to quantify GHE emissions, to identify the influence of the residue of biogas in the release of these gases process in agricultural soils in search for a solution fertilization less harmful to the environment and the greenhouse effect , based on the comparison of three treatments: organic fertilization, mineral fertilization and no fertilization. It was found through the analysis of the measurements that the first was the one which issued N2O, showing that even though coming from the residue of biogas , when returned to the soil, it becomes harmful to the environment and global warming . The cultivation of energy crops can lower or raise the emissions of greenhouse gases, so it is necessary for further research on this question not only in Germany , where such research is in continuity, but also in Brazil, a pioneer in the introduction to his energy matrix of a biofuel produced from cane sugar
