1. ORGANIC RESIDUES IN THE COMPOSITION OF SUBSTRATES ENRICHED WITH BOKASHI BIOFERTILIZER FOR THE SUSTAINABLE PRODUCTION OF Copaifera langsdorffii SEEDLINGS
ABSTRACT One of the great challenges in the post-nursery phase is to plant seedlings in the field. It is, therefore, important to produce them to a high standard of quality aiming to achieve an economically feasible and environmentally sustainable process. For this purpose, the use of organic residues in the composition of substrates, associated with biotech

4. Long-Term Effect of Soil Use and Management on Organic Carbon and Aggregate Stability
ABSTRACT: The conversion of native grassland into farmland causes changes in the soil. Tillage has profound effects on soil organic matter. The intensification of soil tillage decreases soil quality by reducing aggregate stability. Soil aggregate stability and soil organic matter are key indicators for soil quality and environmental sustainability in agro-ec

5. Comparing Methods for Extracting Heavy Metals from Histosols for Establishing Quality Reference Values
ABSTRACT The diversity of methods for heavy metal extraction from soils complicates comparison of results used by environmental agencies to establish quality reference values. The aim of this study was to evaluate three soil digestion methods regarding the solubilizing capacity of Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn, and to propose a standard method to establi

6. Variabilidade espacial e temporal das propriedades quÃmicas do solo e das folhas, qualidade do fruto e produtividade em pomar de laranja Monte Parnaso
The plant nutritional quality influences directly in juice quality. Therefore it is important the knowledge of its spatial and temporary variation in the orchard for a better application and use of the inputs, larger yield and quality of fruit. This way, input maps can be generated for the best use, providing larger yield and better quality of fruits, reduct

7. Horizontal and vertical positional accuracy assement of cartographic products of the amazon region derived from interferometric sar data in X and P bands from ORBISAR sensor / Avaliação da acurácia posicional planialtimétrica de produtos cartográficos da Região Amazônica extraídos de dados SAR interferométricos nas bandas X e P do sensor ORBISAR
The Geographic Service of the Brazilian Army (DSG) is running a major mapping project in Brazil, called ´´Radiography Amazon", the region known as ´´Empty Mapping the Amazon." This area, approximately 1,8 million km$^2$, has not had, to date, appropriate land information mapping at scales larger than 1:250,000, except insufficient cartographic documents

8. Productivity and quality of potato cultivars with doses of NPK / Produtividade e qualidade de cultivares de batata em função de doses de NPK
The demand for fertilizer on the potato crop is the largest among the crops grown in Brazil, ranging from 2.3 to 2.8 t ha-1. Thus, the purpose of this study was to evaluate the yield of potato tubers Ágata, Atlantic Asterix and depending on the levels of N, P and K applied at planting. The experiments were performed and conducted in the municipality of São

9. Phytotoxicity of cadmium and barium and derivation of critical limits in soils / Fitotoxidade de cádmio e bário e derivação de lilites críticos em solos
Soil pollution by heavy metals caused by anthropogenic activities is a problem in many countries. Cadmium (Cd) is one of the most hazardous elements due to its relatively high mobility in soils and transfer to plants. The main human exposure pathway to Cd is through the vegetable consumption and depends on the exposure scenario. Thus, defining a critical lim

11. Technical parameters for the white mold control using air- assisted hydraulic sprayer / Parâmetros técnicos para o controle do mofo-branco na cultura do feijão utilizando pulverizador hidráulico de barra com assistência de ar
The white mold, caused by the fungus Sclerotinia sclerotiorum, is one of the most destructive diseases of the bean plant in the world, especially in crops under conditions of mild temperatures and high soil and air humidity. In general, primary infections caused by this fungus start due to the presence of free water and an exogenous energy source, usually se
