Premium Johnson-Su Compost
1200 Fungi Species

“When conducting preliminary compost fungi spore counts of nine composts, yours scored the highest of the nine other composts that were analyzed and your compost was even of higher quality than my 4-year compost”
- Dr. David Johnson
"Waters Ag Lab analyzed replicated samples of an extract of Midwest Soil Restore's Johnson-Su compost in 2026 using the Biome Makers protocol and database. These samples consistently showed the highest biodiversity I have observed across numerous compost samples and dozens of analyses of various microbial products. What's more, this extract contained solid contingents of functional groups typically low in compost samples, such as plant growth hormone synthesizers, beneficial biocontrol agents, and stress-mitigating microbes such as iron chelators and abscisic acid producers."

We recommend 1 pound of our Premium Johnson-Su Compost applied as an extract per acre. Our compost has a much higher density of fungi than the typical Johnson-Su compost. This allows us to recommend 1 pound per acre, instead of the standard 2 pounds per acre. See our How to Use recommendations.
