13. Geração de mapas de produtividade para experimentos com milho no âmbito de fazenda.
ABSTRACT: Many farmers do not use precision agriculture tools due to high equipment costs and lack of knowledge about this new approach. A number of farmers have, however, conducted on-farm experiments without the help of these new and still expensive tools. One of most important equipments for precision agriculture practices is the crop yield monitor. It ca

14. Sustentabilidade das práticas agrícolas na bacia hidrográfica do rio Gurují município do Conde (PB)
Water has been at the center of world attention, giving rise to several discussions about its uses, conservation, pollution and sustainability. Law No. 9433/97 which established the PNRH - National Water Resources Policy and created the SINGREH - National Water Resources Management (BRAZIL, 1997) is now the leading reference for water management in Brazil.

15. Procedimento para estimativa da intensidade de precipitação máxima admissível em pivô-central com base nas características do equipamento e do solo.
ABSTRACT: A procedure to estimate the center pivot maximum application rate, based on equipment and soil characteristic is presented. It was developed to minimize the surface runoff. To achieve this objective, the Green and Ampt (GA) infiltration equation was modified to include surface sealing and surface storage. The highest application rate is determined

17. Proposta de interconexão do padrão ISO 11783 com redes de sensores sem fio padrão ZigBee. / A proposal for interconnection between ISO 11783 standard network and ZigBee wireless sensor networks.
Precision Agriculture is one of the technological advances used to recoup the treatment of spatial and temporal variability in agricultural crops. Besides other benefits, it tries to improve the exploitation of applied inputs, improve the productivity and reduce production cost as well as lessen the impact on environment caused by excess of input. To achieve

18. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

19. Rede neural artificial para monitoramento em tempo real da concentração de potássio na vinhaça in natura / Artificial neural network for real-time monitoring of the concentration of potassium in the stillage in natura
The cultivation of sugar cane (Saccharum officinarum) has significant presence in Brazils history, from colonization. In its industrial process, are obtained the following products: sugar, ethanol (anhydrous and hydrated), and its main products are: marc - used for power generation - and stillage - re-applied as fertilizer in farming. The use of vinasse on t

20. VALIDATION AND APPLICATION OF A MODIFIED QuEChERS METHOD AND GC-ECD FOR THE DETERMINATION OF PESTICIDE RESIDUES IN RICE GRAIN AND HUSK / VALIDAÇÃO E APLICAÇÃO DE MÉTODO EMPREGANDO QuEChERS MODIFICADO E GC-ECD PARA DETERMINAÇÃO DE RESÍDUOS DE PESTICIDAS EM GRÃO E CASCA DE ARROZ
The current agriculture is characterized by the use of new technologies and equipment, the increased number of agronomic research and the use of a variety of inputs such as pesticides and fertilizers. All this is directly related to human health risks and environmental contamination caused by the intensive use of pesticides. Among the main food consumed by h

21. Dinâmica do carbono e fluxo de gases do efeito estufa em sistemas de integração lavoura-pecuária na Amazônia e no Cerrado / Carbon dynamics and greenhouse gas fluxes in integrated crop-livestock systems in Amazonia and Cerrado
Changes on land use and management influence the accumulation of carbon (C) in soil and the greenhouse gas (GHG) fluxes. In Brazil, especially in Amazonia and Cerrados biomes, the native vegetation has been historically converted in pastures and agriculture causing considerable amount of GHG emissions to the atmosphere. Recently, pastures and agricultural ac

22. Evaluation of boom hydraulic sprayers in the region of Uberlândia-MG / Avaliação de pulverizadores hidráulicos de barra na região de Uberlândia-MG
Any and every manner of pesticide application represents environmental risks, which must be minimized by the use of proper knowledge and technology, assuring a sustainable food production. Often, great importance is given to the pesticide and little to the application technique. The identification of the conservation state and mode of use of the sprayers in

23. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.
