What effect does organic matter have on soil health?

Organic matter plays a crucial role in maintaining and improving soil health due to its multifaceted benefits that contribute to nutrient availability and soil structure.

When organic matter is added to the soil, it decomposes and releases nutrients that are essential for plant growth, such as nitrogen, phosphorus, and sulfur. This process enhances nutrient availability not only through mineralization but also by increasing the cation exchange capacity of the soil, allowing it to hold more nutrients in a form that plants can readily absorb.

Additionally, organic matter significantly improves soil structure. Incorporating organic matter into the soil leads to the formation of aggregates, which enhances aeration, water infiltration, and root penetration. Improved soil structure also promotes better microbial activity, which is vital for nutrient cycling and overall soil health.

The other options fail to capture the essential contributions of organic matter. For example, stating that organic matter has no positive effect on soil quality overlooks the numerous benefits it provides, while suggesting it merely reduces erosion but has no impact on nutrients disregards its critical role in nutrient cycling. Similarly, the assertion that organic matter increases soil pH without affecting nutrients does not recognize the comprehensive influence that organic matter has on the soil environment. Overall, the enhancement of nutrient availability and improvement of soil structure solidify the
