Resumo: The objective of this work was to evaluate the effect of erosion simulated by removal of surface soil layers and the effect of rainfall erosion on wheat and soybean productivity. Thickness of soil layers removed artificially to simulate erosion effects were 0 cm, 3 cm, 6 cm and 14 cm, representing the entire Ap horizon. Wheat productivity did not allow to establish any correlation with thickness of removed soil. The reduction of soybean productivity was 148 kg ha-1 and 105 kg ha-1 per cm of soil removed, in 0 to 6 cm and 0 to 14 cm layers, respectively. Cation exchange capacity and Ca+Mg content, in different soil depth, were the soil attributes that most influenced soybean productivity. Organic carbon content was the only soil attribute to correlate with soybean and wheat yields, in both, rainfall and simulated erosion conditions. Simulation of erosion effect on soybean yield by removal of different soil surface layers can be used, once the difference on soybean productivity compared to the same soil layer lost by natural erosion was less than 6%.

As espessuras das camadas de solo retiradas foram de 0 cm, 3 cm, 6 cm e 14 cm, representando a perda de todo o horizonte Ap. Foram avaliados atributos químicos e físicos do solo até a profundidade de 30 cm. A produtividade do trigo não permitiu estabelecer qualquer correlação com a remoção artificial de camadas de solo, enquanto a da soja foi reduzida em 148 kg ha-1 por cm de solo removido na espessura de solo de 0-6 cm e de 105 kg ha-1 por cm de solo removido na espessura de 0-14 cm. O teor de Ca+Mg e a capacidade de troca de cátions, em diferentes profundidades, foram os atributos do solo que mais influenciaram na produtividade da soja. O teor de C orgânico foi o único atributo do solo que se correlacionou com as produções de trigo e soja, tanto nas condições de erosão causada pela chuva como nas de simulação de erosão. A simulação do efeito da erosão pela retirada artificial de camadas do solo pode ser utilizada para predizer o efeito da erosão hídrica na produtividade da soja em Latossolo Vermelho, uma vez que a diferença do efeito da remoção artificial no rendimento desta cultura em relação às condições sob chuva foi menor do que 6%.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGaertner, CarlosDedecek, Renato AntonioBiscaia, Rui Maranhão2003-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6722Pesquisa Agropecuaria Brasileira; v.38, n.12, dez. 2003; 1443-1449Pesquisa Agropecuária Brasileira; v.38, n.12, dez. 2003; 1443-14491678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6722/3779info:eu-repo/semantics/openAccess2014-08-12T16:15:21Zoai:ojs.seer.sct.embrapa.br:article/6722Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-12T16:15:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
