Atributos físico-hídricos do solo em sistema integrado de produção com diferentes arranjos do componente florestal paricá

O objetivo deste trabalho foi comparar a qualidade estrutural e a curva de retenção de água de um Latossolo Vermelho-Amarelo sob arranjos de linhas simples, duplas e triplas de paricá (Ochroma pyramidale), em um sistema integrado de produção com 50 meses de implantação. O solo foi coletado em cinco pontos de amostragem em relação à distância do renque das árvores. Foram coletadas amostras indeformadas nas camadas de 0,00-0,10 e 0,10-0,20 m para avaliar porosidade, densidade, resistência do solo à penetração, curva de retenção de água no solo e índice “S”. O arranjo florestal com três linhas de paricá promoveu melhores condições físicas ao solo em comparação ao renque de linha simples. As principais alterações ocorreram na camada de 0,10-0,20 m, com aumento da microporosidade e diminuição da criptoporosidade e da resistência à penetração. Os arranjos com paricá em linhas simples e dupla resultam em maiores volumes de água indisponíveis e compactação ao solo.

Termos para indexação:
Ochroma pyramidale; ILPF; qualidade física do solo; curva de retenção; água do solo

Macropores, micropores, and cryptopores in the 0.00-0.10 (A) and 0.10-0.20-m layers (B) under forest component arrangements with paricá (Ochroma pyramidale) in an integrated production systems. Paricá I, planted in single line; Paricá II, in double line; and Paricá III, in triple line. Bars represent the confidence interval of the means. Means followed by equal letters do not differ by the bootstrap test, at 5% probability.
