What is organic matter application primarily used for?

The application of organic matter is primarily aimed at enhancing soil quality. Organic matter plays a crucial role in improving various physical, chemical, and biological properties of the soil. It contributes to soil structure by promoting aggregation, which improves aeration and water infiltration. Additionally, organic matter increases the cation exchange capacity of the soil, allowing it to hold more nutrients that are essential for plant growth. It also fosters a diverse soil microbial community, which is vital for nutrient cycling and overall soil health.

While reducing soil temperature, diminishing soil erosion, and increasing soil acidity may be secondary effects or observations in certain contexts, they are not the main purpose of organic matter applications. Organic matter generally functions to improve conditions within the soil rather than directly manipulating temperature, erosion, or acidity levels in a targeted way. Thus, the primary focus of applying organic matter remains its ability to enhance soil quality, promoting a healthier and more productive growing environment for crops.
