The resulting "super humus" is a highly fertile topsoil, conditioned to promote optimal root growth. This nutrient-rich soil contains all essential elements for plant nutrition in a readily available, water-soluble form. When applied during transplant, even in small quantities, the pure earthworm castings lead to visibly larger and more productive plants.
