ADUBAÇÃO DE SISTEMAS E PRODUTIVIDADE DE CULTURAS

Abstract

Fertilizing systems consists of anticipating crop fertilization so that nutrients, through the cycling process through biological activity, cultural residues, manure and urine from grazing animals, can be made available to the subsequent crop. The objective of this work was to carry out a literature review on the management of the fertilization system in pastures cultivated in winter and grain crops cultivated in the summer. The fertilization of systems aims to supply nutrients to the winter crop with the intention that the cycling promotes the release of these nutrients to the summer crop. The nitrogen fertilization of the pasture allows greater root and shoot growth, promoting greater animal load, weight gain and productivity. Pasture fertilization, plant residues and deposition of manure and urine by grazing cattle maximizes soil biological activity, C and N input and nutrient cycling to the grain crop in summer, which results in greater productivity. Fertilizing systems is a promising technique as long as the winter pasture is fertilized, mainly with N, which allows, through the process of nutrient cycling, the supply of these to the grain crop in the summer.
