What Does Organic Matter Do In Soil?

 · Soil Structure Aggregation Organic matter causes soil to clump and form soil aggregates, which improves soil structure. With better soil structure, permeability (infiltration of water through the soil) improves, in turn improving the soil's ability to take up and hold water. Erosion Prevention This property of organic matter is not widely known.
