Soil pH changes the CEC because Soil type, production history, soil testing, and soil amendments may influence potential microbial risks. Based on their particle size, soils are classified into sandy, loamy, and clayey soils. Clay is the densest and heaviest type of soil which does not drain well or provide space for plant roots to flourish. This triangle is used so that terms like “clay” or “loam” always have the same meaning. Tilling Clay Soil. Loam is a pretty equal mix of the previous three soil types.

Loam is the fourth type of soil. Gardenerdy lists the characteristics of sandy loam soil. Loam can range in colors as well. The medium-textured soil allows air to circulate plant roots while protecting from pests and diseases often caused by other types of poorly drained compacted soils. Clay Loam 15-30 Clay >30 AGRONOMY Soil Cation Exchange Capacity (CEC) Effect of pH on Soil CEC In addition to clay and organic matter, pH also has an effect on CEC. Loam drains well, yet holds moisture and nutrients required for growing healthy plants. Additionally, loam soil is typically composed of these three components in the following weight ratio: 40% sand, 40% silt, and 20% clay. It is not a bad soil.
