SOJA PERENE (Neonotonia wightii): FISIOLOGIA, MANEJO E CONTRIBUIÇÕES PARA A SUSTENTABILIDADE AGROPECUÁRIA

Abstract

Perennial soybean is a promising alternative for sustainable agriculture, especially in areas of low fertility and sandy soils. This legume plays an important role in the recovery of degraded soils through green manure, offering significant nitrogen fixation and increased organic matter, which improves the structure and water retention capacity of the soil. In addition, studies indicate that the cultivation of N. wightii promotes nutrient cycling, can reduce soil compaction and increase porosity, favoring subsequent crops. Adaptable to different conditions, perennial soybeans stand out for their adaptability to soils, being able to improve soil fertility and structure in the long term. Their use in integrated crop-livestock systems not only provides dry matter and forage of high nutritional value for ruminants, but also contributes to the sustainability of the system. In the context of livestock farming, the combination of this plant with tropical grasses favors the durability of pastures and reduces the need for chemical fertilizers, promoting a more sustainable and economical cycle. These characteristics make perennial soybeans an essential tool for agricultural sustainability and environmental conservation, reducing the use of fertilizers and the risk of erosion, in addition to contributing to soil biodiversity and water retention, vital elements for the sustainability and productivity of the agroecosystem.
