🌱 PHYSICO–CHEMICAL PROPERTIES OF SOIL. (Mineral Particles, Soil pH, Soil Aeration, Organic Matter, Humus, Soil Microorganisms) 🌍 Introduction The physico-chemical properties of soil play a crucial role in determining its fertility and suitability for plant growth. These properties include both physical aspects , such as soil texture and aeration, and chemical aspects , such as pH and nutrient availability. Together, they regulate essential processes like water movement, nutrient cycling, and microbial activity in the soil. A clear understanding of these properties is fundamental for agriculture, ecology, and environmental management. Mineral Particles of Soil Mineral particles form the inorganic component of soil and are derived from the weathering of rocks. These particles vary in size and are broadly classified into sand, silt, and clay. Sand particles are the largest and provide a coarse texture to the soil. They allow rapid drainage of water and good aeration but have low nutrie...

 Introduction Edaphic factors refer to the soil-related environmental factors that influence the growth, distribution, and productivity of plants. Soil is one of the most important components of the ecosystem because it not only provides mechanical support to plants but also acts as a reservoir of water and essential nutrients . The physical, chemical, and biological properties of soil together determine its fertility and suitability for plant growth. Soil and Its Types Soil is defined as the uppermost weathered layer of the Earth’s crust , formed by the disintegration of rocks along with the decomposition of organic matter. The process of soil formation, known as pedogenesis , involves the combined action of climate, organisms, parent material, topography, and time. On the basis of particle size and composition, soils are classified into different types: Sandy soil consists of large-sized particles and has a coarse texture. Due to large pore spaces, it allows rapid drainage of ...
