1. Eficiência de absorção de fósforo por diversas espécies de adubos verdes e aproveitamento desse nutriente pelas culturas de cana-de-açúcar e de arroz / Efficiency of phosphorus uptake by several species of green manure and use of this nutrient by crops of sugar cane and rice
Integration of green manures species, which immobilize P, with supplying mineral P sources is one of the most promising agronomic practices for improving the availability of P for the main crop in order to recover soil fertility, increasing soil organic matter and thus optimize the efficiency of mineral fertilizers. The objectives of this work was to select

2. Nitrogen fertilizer management and utilization of nitrogen (15N) from urea, millet and sunnhemp by corn under no-tillage in cerrado soil / Manejo da adubação nitrogenada e utilização do nitrogênio (15N) da uréia, do milheto e da crotalária pelo milho sob semeadura direta em solo de cerrado
Nitrogen is the most absorbed nutrient by corn crop and most affect the grains yield, and its dynamic in soil-plant system is conditioned by management. The research was carried in the Experimental Farm of Faculty of Engineering, Sao Paulo State University (UNESP), Ilha Solteira, located in Selvíria-MS, in a dystrophic Red Latosol, cerrado phase, during 200
