Resumo: This study was conducted in Caruaru County, PE, Brazil, from 1970 to 1990, in an eutrophic Regosol 12% slope, to evaluate different soil tillage methods on soil and water losses and corn (Zea mays L.) and bean (Phaseolus vulgaris L.) productivity under natural rainfall conditions. Data were obtained from four 1,000 m2 experimental plots equiped to collect eroded material from the following treatments: hoe (manual), plow and harrow, double plow and harrow, and only harrow. The mean annual soil and water losses was higher with plowing twice and harrowing and with plowing and harrowing treatments, but, in general, the losses were low in all treatments. This fact was attributed to the large amounts of gravel and coarse sand in the soil profile by reducing direct impact of rain drops and increasing permeability. The more intensive soil tillage methods, by placing richer layer in nutrients deeper, where more water is available, increase nutrient absorption resulting in higher productivity specially for corn. There was significant correlation between corn productivity and average P content from 9 to 14 cm, 10 to 19 cm and 14 to 22 cm depths.

Os dados foram coletados em quatro talhões de 1.000 m2, equipados com coletores de material erosado, compreendendo os seguintes tratamentos: enxada (manual), aração e gradagem, duas arações e gradagem, e gradagem. Comparando as perdas médias anuais de solo e água, verificou-se que a maior intensidade de mobilização provocou as maiores perdas, mas que, de modo geral, foram muito baixas, fato atribuído às quantidades de cascalho e areia grossa existentes no perfil do solo, por reduzirem o impacto das gotas de chuva e aumentarem a permeabilidade do solo. Além do mais, os tratamentos mais mobilizados, por colocarem as camadas mais ricas em nutrientes a profundidades maiores, facilitando a absorção deles, proporcionaram as maiores produtividades médias de milho e feijão, com destaque para o milho. Houve boa correlação da produtividade média do milho com os teores médios de P extraível, nas profundidades de 9 a 14 cm, de 10 a 19 cm e de 14 a 22 cm.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Ademar Barros daResende, MauroSousa, Antonio Raimundo deMargolis, Elias1999-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5167Pesquisa Agropecuaria Brasileira; v.34, n.2, fev. 1999; 299-307Pesquisa Agropecuária Brasileira; v.34, n.2, fev. 1999; 299-3071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5167/2359info:eu-repo/semantics/openAccess2010-07-13T18:11:26Zoai:ojs.seer.sct.embrapa.br:article/5167Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-13T18:11:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
