Resumo: The ability of plants to corn, beans and squash was studied in monocultures and polycultures with two and three species in macroagregação regain ground after conventional tillage in organic production systems. The distribution of water-stable aggregates in diameter classes 8-4, 4-2, 2 to 0.25, <0.25 mm, and weighed wet (DMPU) average diameter, in the 0.00-0.10 layer m, were evaluated at three times t1) before conventional tillage; t2) after preparation, and t3) at the end of the crop cycle. Dynamics of aggregation in time showed the negative effect of soil tillage with disruption of macroaggregates in all treatments, decreasing the DMPU 2.44 mm before cooking to 2.14 after this, even without change occurs in carbon , observed the positive effect of the action of plants in the recovery of aggregation during the cycle of 94 days when the DMPU increased to 2.48 mm.

A distribuição dos agregados estáveis em água nas classes de diâmetro 8-4; 4-2; 2-0,25; < 0,25 mm, e o diâmetro médio ponderado úmido (DMPu), na camada de 0,00-0,10 m, foram avaliados em três épocas: t1) antes do preparo convencional do solo; t2) após o preparo, e t3) no final do ciclo das culturas. A dinâmica de agregação no tempo evidenciou o efeito negativo do preparo do solo com o rompimento dos macroagregados em todos os tratamentos, diminuindo o DMPu de 2,44 mm antes do preparo para 2,14 depois deste, mesmo sem ocorrer alteração no teor de carbono; observou-se o efeito positivo da ação das plantas na recuperação da agregação, durante o ciclo de 94 dias, quando o DMPu aumentou para 2,48 mm.Universidade Federal Rural da Amazônia/UFRA2014-02-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/944Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 57 No 1 (2014): RCA; 80-84Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 57 n. 1 (2014): RCA; 80-842177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
