Uso de índice de vegetação da diferença normalizada na estimativa de produção de forragem

Abstract

The world population continues to grow and, to supply all this demand for food, the productivity of agricultural areas must be increased. Brazilian cattle production system is widely extensive and has a large part of degraded areas, one of the factors being the inadequate stocking rate, which, if excessive, contributes to the advancement of this condition. Thus, to adjust the grazing pressure, it is necessary to know the forage production available in the area; to this end, some methods that can be used for this purpose were raised in this review, also highlighting the use of remote sensing that promotes acceptable predictive conditions and requires less physical resources for its implementation.
