Supports soil biology, structure, and nutrient cycling
C20 feeds existing soil bacteria and fungi. Biological activity helps soil particles form aggregates, creating pore space for air, water, and roots. Soil microorganisms also help release nutrients from organic matter. C20 is not a microbial inoculant and is not a replacement for a soil-test-based fertility program.

Calculated coverage per pallet or tote
Use these planning calculations with the overview rate appropriate to your application. Coverage equals net product weight divided by the application rate, multiplied by 1,000 sq ft. These are calculated treatment areas, not guaranteed results or a recommendation to use the lowest rate.
- At 10 lb per 1,000 sq ft: A 1,600 lb pallet covers 160,000 sq ft; a 1,500 lb tote covers 150,000 sq ft.

Gardening rate: Apply 2 lb per 100 sq ft for flower beds and landscape or vegetable gardens.
Application and handling
- Select the rate appropriate to the intended use.
- Spread evenly using granular turf equipment when temperatures are above freezing.
- Irrigate after application. For new sod, the manufacturer recommends applying beneath the sod during installation.
C20 needs oxygen. Do not apply to soils with standing water or continuously saturated soils, or cover treated areas with impervious barriers such as water bags or landscape fabric. Broad-spectrum fungicides, biocides, and fumigants are exceptions to compatibility with most soil treatments. Store dry and away from pests.
Tree and shrub cautions: Do not apply to plants already dead or dying. For significantly stressed plants that are not dead or dying, resolve the cause of stress before applying at half rate. Remove landscape fabric before treatment. Apply outside the water-bag perimeter, not beneath a water bag.
