What is one major benefit of soil organic matter?

One major benefit of soil organic matter is that it improves the soil's water-holding capacity. Organic matter, such as decomposed plant and animal materials, has a unique structure that allows it to absorb and retain water more effectively than mineral-based soil components. This increased ability to hold water is crucial for plant growth, as it ensures that moisture is available to plant roots during periods of drought or low precipitation. It also enhances the soil’s overall health, promoting a balanced ecosystem within the soil that supports beneficial microorganisms and contributes to nutrient cycling. Through the stabilization of soil aggregates, organic matter reduces the risk of erosion and compaction, making it vital for sustainable agricultural practices and land management.
