Productivity of Marandu grass as a function of liming and phosphate fertilization in a Typic Hapludult from Amazonia

Abstract: Little information is available concerning liming and phosphate fertilization for grassland maintenance in Amazonia. The dry-weight yield of Brachiaria brizantha was assessed over three harvest periods as a function of top-dressing with lime and phosphorus. The experimental design consisted of fully randomized blocks with four replicates arranged in subdivided plots according to the sampling season (plots), phosphorus application rate (0, 30 and 60 kg ha -1 P 2 O 5 ) (subplots) and presence or absence of limin… Show more

“…The pastures are used as the primary source of feed for cattle in the Amazon region (Pinheiro et al 2014). However, the main problems related to the establishment and maintenance of pastures in Brazilian Oxisols (Alves , largely because these areas are partially or totally degraded (Dias-Filho, 2015) or due to improper practices (Guarda & Guarda, 2014), absence of fertilization or occurrence of sudden death syndrome Uroclhoa brizantha grass (Ribeiro-Junior et al 2017).…”

“…Como na maioria das regiões tropicais, em geral, há predominância de solos com falta, principalmente, do nutriente fósforo, ocorre assim, a exigência da reposição desse nutriente por adubação fosfatada (Pinheiro et al, 2014), para tornar as áreas produtivas.…”

“…No Brasil, aumentos na produção com a calagem têm sido demonstrados por seu efeito no aumento do pH, na redução de Al e Mn tóxicos, no aumento da absorção de N, P, K e S e no fornecimento de Ca e Mg. A reação do calcário, entretanto, é geralmente limitada ao local de sua aplicação no solo. A calagem não tem um efeito rápido na redução da acidez do subsolo, que depende da lixiviação de sais através do perfil do solo (PINHEIRO et al, 2014).…”
