Influência da distribuição de poros por tamanho na condutividade hidráulica do solo saturado.

Abstract

In order to evaluate the influence of pore size distribution on saturated soil hydraulic conductivity, samples were collected from the superficial layer (0-20 cm) of six soils (RQ, LVdf, LVAq, LVd, LVAd e RU) located in the region of Lavras, Minas Gerais State, Brazil. Soil samples were submitted to the analyses of saturated soil hydraulic conductivity and pore size distribution. Results allowed verifying that saturated soil hydraulic conductivity values were more affected by soil pores with diameter greater than 0,05 mm (macroporosity).
