Worm Castings Benefits
It is said that worm castings are the richest natural fertilizer. They are a mixture of enzymes, bacteria, a remnant of plant matter and earthworm cocoons. Worm castings are high in water-soluble plant nutrients. Compared to topsoil, they contain 50 percent more humus.
Moreover, worm castings are also rich in minerals that are vital for plant growth.
These minerals include phosphorus, nitrates,potassium, magnesium, and calcium. Worm castings may also contain copper, manganese zinc, nitrogen, carbon, iron, and borax. They are immediately available to plants. However, they are slowly released so that they will last longer.
They offer numerous benefits not just for plant growth. The best thing about this type of organic matter is that it is also environment-friendly.
