Árvores de Baginha (Stryphnodendron guianense (Aubl.) Benth.) em Ecossistemas de Pastagens Cultivadas na Amazônia Ocidental

Abstract: RESUMO -Foi estudado o efeito de árvores isoladas de baginha (Stryphnodendron guianense (Aubl.) Benth.) sobre alguns aspectos do ecossistema de pastagens cultivadas na Amazônia Ocidental. Avaliaram-se, sob a copa das árvores e na área adjacente a pleno sol, a fertilidade do solo, a serapilheira, o teor de água no solo, a transmissão de luz ao pasto, a disponibilidade de forragem e as composições química e morfológica das gramíneas (mistura de Brachiaria decumbens e B. brizantha cv. Marandu). As árvores de bagi… Show more

“…The results of this work are in agreement with Reis (2007), who found that shaded pasture with ipê felpudo (Zeyheria tuberculosa) had 8.62% CP compared to a (U. brizantha) pasture with 5.19% CP. Andrade et al (2002) found in shaded pasture a level of CP 50% higher than that found in full sun areas, suggesting increase in soil N with increase in organic matter under trees. The average values for CP, LIG and NDF found by Paulino et al (2005) in FPSs, and by Lin et al, (2010) in SPSs are in agreement with what this study has found.…”

“…These authors explain that, in most plants, light stimulates absorption of H 2 PO 4 -, nevertheless there is no consensus in literature if light changes P concentrations due to variation in P concentration among forage species. Conversely, levels found by Andrade et al (2002) were numerically equal among shaded and not shaded forage, with a difference of only 0.14%. In this experiment, shading due to the presence of trees appeared to significantly increase the availability of phosphorus (Table 1).…”

“…Nesse sentido, a leguminosa arbórea é uma opção pouco lembrada para incorporação de nitrogênio ao ecossistema da pastagem (ANDRADE et al, 2002). Evangelista e Lima (2006) relataram que, com a busca de sistemas autossustentáveis, passou-se a valorizar os bons efeitos (dependendo da densidade e da espécie) proporcionados pelas árvores nas pastagens, tanto para as forrageiras quanto para os animais.…”

“…Segundo Andrade et al (2002), uma das limitações para a implantação de sistemas silvipastoris é a difi culdade para introdução das árvores em pastagens estabelecidas. Constatou-se que a implementação do método de proteção das mudas, com arame farpado e uma estaca, implica o acréscimo de aproximadamente 9% no custo operacional da exploração bovina de corte, o que signifi ca redução de 27% no retorno bruto (Montoya & Baggio, 1991).…”
