Effect of Amazonian tree species on soil and pasture quality in silvopastoral systems

ABSTRACT With the expansion of livestock in Amazon region, a high percentage pasture areas are degraded and unproductive. Novel strategies needed, including use native tree species, to simultaneously achieve economic ecosystem benefits. This study aimed at assessing effects five multipurpose species on soil fertility forage quality Urochloa brizantha pastures southern Amazon. Soil samples were collected under crown adjacent 25 isolated trees belonging during dry rainy season. The presence positively affected level potassium, calcium manganese soil, as well mineral matter crude protein forage, especially season, suggesting protective effect against seasonal drought. had variable quality. Apeiba tibourbou higher potassium levels, while Handroanthus serratifolius fiber content. Our results indicate that it is important diversify silvopastoral systems through contributing design novel region. Common with widespread natural distribution could be used complementary aspect management provide drought, contribute enhanced nutrient cycling even increase
