We supply high-biology, mature Johnson–Su compost inoculant to gardeners and farmers across the USA — lab-tested for the fungi and bacteria that put life back into depleted soil.
We send samples out for independent lab testing — not just to prove it to customers, but to prove it to ourselves.
We have biology to help your plants grow with little or no added fertilizer. If you apply our compost at 1 to 2 pounds per acre, you do not need to apply phosphorus, and can cut back nitrogen 25% to 50% the first year.
If you apply our compost at 1 to 2 pounds per acre, you don't need phosphorus at all, and can cut nitrogen 25–50% in the first year — while the biology keeps building.
See product optionsOur mature compost supports regenerative agriculture. We chop leaves, wet them, and fill wire cages, then keep them moist for two years. The fungi and bacteria from the leaves and air multiply into a powerful biological inoculant, applied at 1–2 pounds per acre.
It's possible to grow plants that resist disease and harmful insects. Johnson–Su compost contains 122 species of fungi and 722 species of bacteria to strengthen plants from the root up.
Regenerating the soil is our primary goal. We're a small family operation — help us by starting on your own land, one pound at a time.
We raised our family on the land of Colville Compost. In the 1800s, when this area was settled, it was called Colville community — we think it's a good name for our compost. Don and Talitha purchased this 3-acre parcel in 1976, and for 25 years kept a 2-acre blueberry patch. It was here we learned the importance of good soil health.
Our compost is available in quantities of 1 pound or more. Most orders ship the same day. Tell us your plans and how much you want, and we'll ship on your preferred date — or arrange to visit us for a tour and pick up your order in person.
This hoop house was designed to minimize the effect of weather on the compost. It worked well in NW Arkansas for 3 years before we moved to Kentucky.
We ship in boxes up to 50 pounds via FedEx — but you can order any amount. We prefer payment by check for bulk orders; contact us directly to set up quantity and shipping details.
