ORGANIC SOIL AMENDMENTSWhat are worm castings (vermicast) ?A worm casting (also known as worm cast or vermicast) is a biologically active mound containing thousands of bacteria, enzymes and remnants of plant materials and animal manures that were not digested by the earthworm. One of its components, humic acid, provides many binding sites for plant nutrients, such as calcium, iron, potassium, sulfur, and phosphorus. Castings contain plant nutrients encased in mucus membranes secreted by the earthworms. Castings contain five times the available nitrogen, seven times the available potash and 1 1/2 times more calcium than that found in 15cm of good topsoil. Therefore, castings are supplied with available nutrients. The nutrients are also water soluble and immediately available to plant life. You will find that most potting soils have nutrient life of 2-5 days, where worm castings will last up to six times as long as other types of potting soils. You will need five times as much potting soil to do the same job as the worm castings. So, in the long run, worm castings are much cheaper and do a much better job. Also castings hold 2-3 times their weight in water. That means you water less and the pot will stay damper for a longer period. Worm castings will not burn your plants, unlike using many fresh, raw manures (cow, horse, etc.) which can burn root systems if not applied properly.
