Additional Information

Rock Powders and Soil Amendments

Thriving sustainable agriculture is built on the ground of a healthy soil. In fact, organic certification requires a soil management plan. Do a soil test to determine your soil’s needs before embarking on a program of soil improvement.

Rock powders and soil amendments used with a program of crop rotation, composting and cover cropping will enhance fertility, improve soil tilth, promote disease resistance, support beneficial soil microorganisms, and even help restore balance to the garden and the world around it. Application rates vary depending on soil type and results of soil tests. Used with organic fertilizers, rock powders and soil amendments will help address immediate fertility needs as well as long-term requirements of sustainable growth. Rock powders can be applied directly to soil but their nutrients will be more readily available to plants if incorporated into compost.

Organic Certification

Inoculants, soil amendments, fertilizers, livestock supplies and pesticides are labeled as:
OMRI: Organic Materials Review Institute. Most state certifying agencies, including MOFGA, accept OMRI approval.
MOFGA: Maine Organic Farmers & Gardeners Association. Reviewed by MOFGA and allowed for use on MOFGA-certified farms. Check with your certifier.
WSDA: The Washington State Department of Agriculture’s Organic Certifying division has approved these products for use in organic agriculture in Washington State. MOFGA has indicated that they will accept products on this list for their certification program. Check with your certifier.
Nat’l List: One-ingredient products on the NOP* List of Allowed Substances (subpart G of the Organic Foods Production Act, sections 205.601-606). Check with your certifier.
AYC: Products whose active ingredient is on the list of allowed substances, but which are not on the OMRI or WSDA list. Ask your certifier.
Not Allowed: A few of the products we list are not allowed for organic production but we think they have a place in sensible agriculture and can be used when certification is not an issue.
