Soil composition is the study of the various components that make up soil, including minerals, organic matter, water, and air. Understanding the composition of soil is important because it directly affects the health of plants, the fertility of the soil, and the overall ecosystem. Researchers in this field study the physical, chemical, and biological properties of soil to understand how these components interact and how they can be managed to improve soil health and productivity. Soil composition research plays a key role in agricultural, environmental, and ecological studies.
