Importance of Soil: Food, Foundation, Minerals and More

Soil plays a crucial role in producing food and fiber, serving as a foundation for infrastructure, providing minerals, participating in photosynthesis, filtering water, hosting organisms, and decomposing waste. Factors like parent material, climate, living organisms, topography, and time influence soil formation. Soil consists of air, minerals, organic matter, and water. The texture of soil is determined by different-sized particles such as sand, silt, and clay. Understanding soil composition and texture is essential for sustainable land management.
