16. Fertilizantes de leguminosas: tecnologia inovadora de adubação verde para provisão de nitrogênio em sistemas orgânicos de produção. / Legume fertilizers: innovative technology of green manuring for nitrogen supply in organic farming systems.
One of the main limitations to the organic food production is the reduced availability of low cost and efficient nitrogen (N) sources. Green manuring practices, in rotation or intercropped, have been used, but hardly are they able to supply crop needs. This dissertation presents an innovative technology of green manuring, derived of the cutting, dehydration

20. APPLICATION OF PRECISION AGRICULTURE TECHNIQUES IN SMALL FARMERS / APLICAÇÃO DE TÉCNICAS DE AGRICULTURA DE PRECISÃO EM PEQUENAS PROPRIEDADES
The adoption of precision agriculture techniques finds great limitation because of the high cost, not always guaranteeing the expected economic return. Among the consequence of this elevated cost it is the restriction use of this technology in small farmers, characterized by the family farm. The present work approaches a bibliographical study about the situa

21. Farm machinery utilization in a row-crop producer region / Diagnóstico da mecanização em uma região produtora de grãos
The intensive farm machinery use in Brazil started in the 1960?s with the establishment of national tractor industry and followed by farm machinery industries. These industries promoted a quick expansion in agricultural mechanization, which today is essential. Although with undeniable benefits, agricultural mechanization was influenced by external technology
