Determination of calcium in soil
WebFor any given soil the availability of plant nutrients like calcium, magnesium and potassium increases with the degree of base saturation. It is evident that soils with large amounts of organic colloids or 1: 1 type clay colloids can supply the nutrient cations to plants at a much lower degree of base saturation than soils high in 2: 1 type ... WebAug 22, 2024 · Soil CEC typically increases as clay content and organic matter increase because cation exchange occurs on surfaces of clay minerals, organic matter, and roots. Soils in Ohio can encompass a wide CEC range, but typically fall somewhere …
