Abstract
For growth of plants and crop productivity, soil is a crucial component. However, just a very small portion of the soil is genuinely fertile for farming these days, and if we managed it incorrectly, it could be depleted. It has been demonstrated that organic nutrients increase crop production, quality, and yield, which in turn improves the quality as well as richness of the soil's characteristics and creates a more favorable environment for the soil's beneficial microorganisms. According to reports, organic carbon in the soil and soil matter are the most significant indicators of soil quality and soil health. They are also advantageous for the sustainability of agriculture. Crop residue can be used effectively to improve soil quality and increase or maintain SOM's physical and chemical qualities.
