Soilremain
Soilremain refers to the organic and inorganic components that persist in soil after the decomposition of dead organic matter. These remaining elements are crucial for soil health and fertility. Organic remain includes humus, a stable, dark-colored substance formed from the breakdown of plant and animal residues. Humus improves soil structure, water retention, and nutrient availability. Inorganic remain consists of mineral particles, such as sand, silt, and clay, which originate from the weathering of rocks. These minerals provide essential nutrients for plant growth.
The process of soil formation is a continuous cycle of addition, transformation, and removal of materials. Soilremain
