Aug 01, 2001· 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.
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel
If you have sandy soil, use Clean Green as a conditioner by mixing in up to 50% of the tilled depth. This method will provide high humus content that will provide increase the water holding capabilities of your soil. If you have clay soil, follow the same method. Clean Green's high humus content will increase aeration and drainage for clay soils.
