1. Methods and rates of poultry litter fertilization for corn silage in organic system
ABSTRACT. The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at

2. Nitrous Oxide Emissions in a Wheat/Corn Succession Combining Dairy Slurry and Urea as Nitrogen Sources
ABSTRACT: The impact on nitrous oxide (N2O) emissions caused by combining dairy slurry (DS) and urea to supply crops with nitrogen (N) is still not well characterized. The main objective of this study was to compare the differences between N2O emissions in the cases of exclusive use of urea and the combined use of DS and urea as N sources to no-tillage wheat

3. STRATEGIES FOR IMPROVING NITROGEN SUPPLY TO CORN AND WHEAT FROM PIG MANURE AND TO REDUCE SOIL NITROUS OXIDE EMISSIONS / ESTRATÉGIAS PARA MELHORAR O FORNECIMENTO DE NITROGÊNIO AO MILHO E AO TRIGO POR DEJETOS DE SUÍNOS E REDUZIR A EMISSÃO DE ÓXIDO NITROSO DO SOLO
The swine manure is a major source of nitrogen (N) to crops, although its inappropriate use can lead to N losses which in return pollute environment and reduces its value as organic fertilizer. The sustainability of pig farming depends on strategies that could improve crops N utilization from pig slurry and mitigate harmful environmental impact caused by its

4. Uso do clorofilÃmetro e de agricultura de precisÃo no manejo da adubaÃÃo nitrogenada do milho / Chlorophyll meter and precision agriculture use in nitrogen sidedressing management for corn.
The complex dynamics of nitrogen (N) exerts influence on the management of nitrogen fertilization for corn crop. In this sense, tools which aim to detect the spatial and temporal variability of the factors linked to its availability, as well as, the timing between topdressings and the phenological stages of highest demand for the nutrient are essential strat

5. Análise de crescimento e produtividade de duas variedades de cana-de-açúcar (Saccharum spp) influenciadas por doses de fósforo
The knowledge of the leaf area is required every time the sugarcane is subjected to evaluation in which different varieties are compared or submitted to different environmental conditions, managements or fertilizations, therefore evidently showing alteration in dimensions of the plant leaves, so affecting the photosynthetic process. Although the higher breat

6. Corn fertilization with ammonium sulfate in a Brasília Cerrado soil under Brachiaria decumbens pasture. / Fertilização com sulfato de amônio na cultura do milho em um solo de cerrado de Brasília sob pastagem de Brachiaria decumbens.
Crop/livestock integration systems have been adopted in the cerrados, since this is a technology for pasture recovery and renovation, used in association with annual crops, such as corn. In this system, the pasture is recovered and maintained productive by crop fertilization. Nitrogen is prominent among the nutrients applied in fertilizations; it undergoes s
