Why Earthworm Castings

The most important part of the soil is humus—the black part of the soil that remains once most of the organic material breaks down. The presence of humus in the soil allows air and water to move more freely. It can also be thought of like a big “sponge” for soil as it is capable of holding up to 90% of its weight in water. Humus ensures that nutrients and water are not washed through the root zone. A “nutrient soup” is created that the roots feast on for a long time, which saves water.
