Frequently Asked Questions
Vermi is Latin for worm. Vermicompost is a mixture of vermicast (basically, worm poop) and composted organic matter (such as vegetable waste, leaves, lawn clippings, and manure). Pure vermicast (also called worm castings or worm humus) is created when worms eat everything, leaving behind nothing but their nutrient rich poop. You can think of vermicompost as what you get when worms don’t finish everything on their plate, and the leftover bits have decomposed (composted) and are ready for consumption by other microbes and plants. In general, vermicast is more nutrient rich, but vermicompost has more biological diversity as well as higher microbial and fungal populations.
Pure vermicast varies in quality based on production techniques, diversity of ingredients used in the composting process, and the time and manner that they are stored after processing. We believe a casting-rich vermicompost is superior to pure vermicast. By using many ingredients from food waste to hay, manure, and paper built in a “lasagna” layered technique, and slowly letting red wiggler worms and diverse biota do its work, we at Partridge Creek Farm are building the most biologically diverse and nutrient rich soil amendment available for natural growing practice.
