Worm castings contain a highly active biological mixture of bacteria, enzymes, remnants of plant matter and animal manure. Castings are rich in water-soluble plant nutrients and contain more than 50% more humus than what is normally found in topsoil. Worm castings are packed with minerals that are essential for plant growth, such as concentrated nitrates, phosphorus, magnesium, potassium and calcium. It also contains manganese, copper, zinc, cobalt, borax, iron, carbon and nitrogen.
Worm castings can be used as an ingredient of potting soil or as plant nutrients for plants in and around the house. It can also be used as a planting additive for trees, vegetables, shrubs and flowers. When used as mulching material, castings will ensure that the minerals are absorbed directly into the soil when it is watered. Best of all, nutrients and minerals are immediately available to the plant, without the risk of ever burning it.
