Soil science is the study of soil as a natural resource, focusing on its formation, classification, and mapping. It examines the physical, chemical, and biological properties of soil, which are essential for understanding how it supports plant growth and affects the environment. Soil scientists analyze soil samples to determine nutrient content, pH levels, and moisture retention, which are crucial for agriculture and land management. This field also explores the interactions between soil and other components of the ecosystem, such as water, air, and organisms. By understanding these relationships, soil science helps in addressing issues like soil erosion, pollution, and sustainable land use practices.
