NEET BIOLOGY

Detailed explanation-1: -Chemical properties of the soil are important to soil fertility, plant growth and reproduction. That is why it is important to understand how chemical properties of the soil interact to affect the soil’s capacity to store and release nutrients, and how soil chemistry can affect soil structure.

Detailed explanation-2: -The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture.

Detailed explanation-3: -All soils contain mineral particles, organic matter, water, and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry, and colour.

Detailed explanation-4: -Some important physical and chemical properties of soil are mineral content, texture, cation exchange capacity, bulk density, structure, porosity, organic matter content, carbon-to-ni-trogen ratio, color, depth, fertility, and pH.
