Resumo: The objective of this work was to evaluate soil losses by erosion and the native pastures productivity with and without introduction of exotic species under different systems of soil management. Soil losses were evaluated under natural rainfall conditions measuring changes in the level of soil surface by erosion process. It were utilized metal pines stuck into the soil (dystrophic Cambisol) (Inceptisol). The tested treatments, in plots measuring 36 m2 each, were the following: Brachiaria brizantha (Bb) sowed in pits; Bb in pits + scarification among pits; Bb in furrows; Bb broadcasted in scarified soil; Andropogon gayanus (Ag) sowed in pits; Ag in pits + scarification among pits; Ag in furrows; Ag broadcasted in scarified soil; native pasture with scarification; native pasture. Plots without vegetation and management practices were also maintained. A global analysis of data obtained suggests the possibility of improvement of these native pastures by scarification, liming and fertilization, and the potential of exotic species introduction using these management practices aiming to increase the available forage quantity, in accordance with the soil losses tolerance limits.

A avaliação das perdas de solo foi feita sob chuva natural, por meio da determinação de mudanças de nível da superfície do solo, utilizando-se pinos de metal cravados no solo (Cambissolo distrófico). Os tratamentos testados, em parcelas de 36 m2, foram os seguintes: Brachiaria brizantha (Bb) semeada em covas; Bb em covas + escarificação entre covas; Bb em sulcos; Bb a lanço em solo escarificado; Andropogon gayanus (Ag) semeado em covas; Ag em covas + escarificação entre covas; Ag em sulcos; Ag a lanço em solo escarificado; pastagem nativa com escarificação; e pastagem nativa (testemunha). Também foram mantidas parcelas sem vegetação e sem nenhuma prática de manejo. Uma análise global dos resultados obtidos enfatiza a possibilidade de melhoramento dessas pastagens nativas mediante escarificação, calagem e adubação, e a potencial introdução de gramíneas exóticas com o uso dessas práticas de manejo visando aumentar a quantidade de forragem disponível, dentro dos limites de perdas toleráveis por erosão.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, DjailCuri, NiltonMartins Ferreira, MorzatRicardo Evangelista, AntônioBeato da Cruz Filho, AgostinhoGeraldes Teixeira, Wenceslau1998-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4839Pesquisa Agropecuaria Brasileira; v.33, n.2, fev. 1998; 183-189Pesquisa Agropecuária Brasileira; v.33, n.2, fev. 1998; 183-1891678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4839/6948info:eu-repo/semantics/openAccess2014-11-14T16:17:34Zoai:ojs.seer.sct.embrapa.br:article/4839Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-14T16:17:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
