Soil composition is an important aspect of nutrient management. While soil minerals and organic matter hold and store nutrients, soil water is what readily provides nutrients for plant uptake. Soil air, too, plays an integral role since many of the microorganisms that live in the soil need air to undergo the biological processes that release ...

What Is Soil Composition? Soil composition refers the type and quantity of substances found in soils. Soil substances occur in four basic components: minerals, organic matter, water and air. The combination of these substances varies among soils but generally consists primarily of minerals followed by equal parts water and air and a small ...

These bound nutrients interact with soil water to buffer the soil solution composition (attenuate changes in the soil solution) as soils wet up or dry out, as plants take up nutrients, as salts are leached, or as acids or alkalis are added.

As a result, the plants have a harder time to reach the nutrients since they are carried away too quickly. Typical growing soil consists of around 20-30% air, 20-30% water, 5% organic matter and 45% minerals. Your plants’ general health is heavily dependent upon the soil composition.
