Worm Castings

OASCO carries ONLY the highest quality worm castings available on the market, which are available bagged (pallets of worm castings typically for resale) and bulk quantities (bulk totes, supersacks and walking floors), for farms, custom mixers, landscape companies, etc.

For worm castings, NPK values should be ignored as these values are meaningless in regard to these products. Quality worm castings have high active biology counts, high chitin degrader and cellulose degrader levels, and little to no useless filler materials.  Feed materials used for raising the worms are the single most important factor regarding worm castings quality. The best worm castings are typically fed a wide diet of pre-consumer food wastes. This provides a very wide biology spectrum.
