Clay particles, being much smaller, pack tightly together, leaving little space for air. Based on their particle size, soils are classified into sandy, loamy, and clayey soils.

By definition, loamy soils are friable, possessing a mixture of clay, sand, and humus (and/or silt) that is ideal for growing plants.While those new to gardening and landscaping are probably familiar with terms such as "clay" and "sand," they may well be unfamiliar with "humus," so let's gain a better understanding of the meaning of that word before proceeding. It is the layer of mineral soil with the most organic matter accumulation and soil life. These are present only in older, well-developed soils, and generally occur between the A and B horizons. Each layer differs in feel (texture), colour, depth and chemical composition. Soil – Soil Types: Sandy - Clayey - Loamy. Next 2 lines says that this layer is depleted of (eluviated of) iron, clay, aluminum, organic compounds, and other soluble constituents. A soil horizon is a layer generally parallel to the soil surface, whose physical characteristics differ from the layers above and beneath. Silt is the deposit in river beds.

They may be on top of either mineral or organic soils. Loamy soil contains equal amounts of the mineral components. Sandy Soil. Their adsorption mechanisms are different too. Key Difference: Soils are mainly classified on the basis of their nature and composition.There are many different types of soils like – black soil, red soil, laterite soil, alluvial soil, mountain soil, etc. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc. There are mainly 4 types of soil which are explained in this video.
