What is Vermicompost?
Vermicompost is very similar to pure worm castings. The primary difference is that vermicompost has been screened 1 less time than castings, so vermicompost will contain trace amounts of compost while worm castings are more pure. In lab tests, vermicompost is proven to have a similar biological composition as pure castings, and vermicompost also similar benefits in soil structure and porosity, water retention, and nutrients.
So vermicompost provides many of the same benefits as pure castings, but at a lower cost. Soil distributors and soil mixing companies concerned with appearance usually opt for pure worm castings. Vermicompost is a similar but more cost-effective option for gardeners, farms, and anyone not as concerned with the appearance of the castings.
Brothers Worm Farm Bulk Vermicompost

Our worm casting products are recommended by 2 national soil testing laboratories:
"The biology levels are stunning and fantastic! Good bacteria and fungi levels, activity levels are great too. Protozoa populations are perfectly balanced and stunning! Normally you’d use 50lbs as a top dress per 100 sq ft, but with this material, you can get away with 20-25lbs because the biology is so rich in this material." - Founder and Director, National Soil Testing Lab

Our Bulk Worm Castings Process
Brothers Worm Farm’s bulk vermicompost and worm castings are produced from our red wiggler and compost earthworms. We have implemented a standardized and repeatable approach to producing worm castings that ensures consistent and quality worm castings and overs.
We do not add filler of any kind to our vermicompost, so the bulk vermicompost super sacks consist of worm castings, compost the worms did not fully process, and small amounts of other organic matter (and sometimes a few worms and cocoons!).
