Soils of Uttarakhand  Soil is a dynamic natural body that forms at the Earth's surface through the weathering of rocks and the decomposition of organic matter over thousands of years. It is composed of mineral particles, organic matter, water, air, and living organisms, all of which interact to support plant growth and sustain terrestrial ecosystems. Soil serves as the foundation of agriculture, regulates the hydrological cycle, stores carbon, recycles nutrients, and provides habitat for countless organisms. The characteristics of a soil depend upon five major soil-forming factors: p arent material, climate, topography, organisms, and time , as proposed by Hans Jenny. Because soils differ greatly in their physical, chemical, and biological properties, scientists have developed classification systems to organise them systematically. The two most widely used global systems are the USDA Soil Taxonomy developed by the United States Department of Agriculture and the World Reference Bas...
