Webb28 sep. 2024 · Why soil that have a high clay content has a slower permeable or infiltration rate? Sandy soils are known to have high permeability, which results in high infiltration rates and good drainage. Clay textured soils have small pore spaces that cause water to drain slowly through the soil.

"WebbLength differences of vertical and horizontal cracks are negligible. Soil peds often have thin, discontinuous, clay films on surfaces and tend to break more easily along the vertical axis than in the very slowly permeable soils. Soils frequently have thick surface and transitional horizons from the surface to the most clayey horizon in the profile. " - Slow permeable soil

Webb1)Slow Permeable soil The soil which have infiltration rates less than 6 cm/ day due to high clay content of the soil. Constraints Low infiltration rates reduces entry of water into the soil and therby increases the run-off and accelerates soil erosion. This further leads to nutrient removal from the top soil .Hence decreases fertility WebbHowever they will avoid slowly permeable soils for the following reasons: ... High soil moisture content in the spring delays plant growth as the soils are slow to warm up, Soil permeability during the period of new root development in the late winter can encourage the development of soil pathogens such as Phytophthora spp. root rot (5).
