Introduction to Clay Minerals & Soils

Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

Different Minerals and Clay Minerals in Soil. The mineral part of soil is made up of many types of minerals. A Primary mineral comes directly from rock: like pyrite (fools gold). A list of minerals and rocks can be found here. These minerals break down into different types of clay minerals. View an animation of breakdown of primary minerals here.

Plant nutrients in the soil

When applied to soil, nitrogen is converted to mineral form, nitrate, so that plants can take it up. Soils high in organic matter such as chocolate soils are generally higher in nitrogen than podzolic soils. Nitrate is easily leached out of soil by heavy rain, resulting in soil acidification.
