WebThe garden soils with the best porosity are loam soils, which are mixtures of clay, silt and sand with organic matter. It is ideal for growing plants since it holds water and nutrients, releases them to plants roots and drains excess water. Their porous nature allows rainwater penetration, reducing nutrient and mineral runoff. WebTexture, that is, the percent of the primary particles of sand, silt, and clay, usually has a minor effect on hydraulic conductivity, except for disturbed soil materials. The hydraulic conductivity of natural soils in place varies from about 30 m/day for a silty clay loam to 0.05 m/day for a clay (Kirkham, 1961a, p. 46; Kirkham, 1961b).
