COMPORTAMENTO DE LEGUMINOSAS ANUAIS UTILIZADAS COMO ADUBOS VERDES NA REGIÃO SEMIÁRIDA MINEIRA Behavior of annual legumes used as green manure in the semi-arid region of Minas Gerais, Brazil

Abstract: Devido à grande degradação física e química dos solos da região semiárida mineira é cada vez mais necessáriaa adoção de práticas conservacionistas. A técnica de adubação verde, realizada por meio do uso de espéciesleguminosas, apresenta-se como uma prática alternativa visando restaurar a capacidade produtiva dos solosda região. Diante do exposto, o objetivo do presente estudo foi conhecer o comportamento de algumas espéciesleguminosas anuais, nas condições edafoclimáticas de Salinas (MG), gerando tecnologias q… Show more

“…The spontaneous vegetation was composed of the following predominant species: Commelina benghalensis L., Macroptilium atropurpureum Desmodium tortuosum and Ancanthorpermun hispidun DC. The green manure species were chosen because they are well adapted to the soil and climatic conditions of the region and present good biomass production (FARIA et al, 2007;CAVALCANTE et al, 2012;MASSAD et al, 2013;MAGALHÃES et al, 2013;SANTOS et al, 2013). Table 2 shows the seed quantities per species in each vegetal cocktail.…”

“…In Brazilian semi-arid region, there are reports of green manures phytomass additions ranging from 1.7 to 11 Mg.ha -1 (Massad et al, 2013), related to the species, soil fertility, climatic conditions, C/N and lignin/total N, among others (Pariz et al, 2011;Teixeira et al, 2011). However, the minimum quantities of biomass were not defined for the positive balance of addition and accumulation dry matter, carbon and nitrogen in the soil, to increase the soil or agroecosystems quality.…”
