While trace mineral products like Azomite® can be helpful for maintaining background levels of a wide variety of elements, they don’t have the juice to correct actual deficiencies of specific micronutrients. Note that on certified organic operations, these products may only be applied if there is a documented micronutrient deficiency. Dilute 1 part liquid micronutrient in 100 parts water (⅜ oz in 4⅔ cups water, 1 pint in 12½ gallons water) before applying.
Biomin Calcium helps to strengthen the cell walls of plants, improving crop quality, disease resistance and storage capacity. Calcium mobility in plants is limited and uptake may be reduced by cool or humid conditions. Mid-season foliar applications of calcium can help prevent problems like blossom end rot and bitter pit. Contains 5% calcium chelated with an amino acid complex. Apply 1–4 quarts/acre (¾–3 oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary. Registered in New Hampshire by JH Biotech as Safergro Biomin Calcium.
Biomin Copper is necessary for efficient photosynthesis and respiration and affects the sugar content and flavor of produce. Copper availability may be limited by alkaline soils, high organic matter levels, saturated soils, or excessive zinc, nitrogen or phosphorus. Contains 4% chelated copper derived from copper sulfate. Apply 1–4 pints/acre (⅜–1½ oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary.
Biomin Iron 1-0-0 is essential for chlorophyll development and function, and is also involved in nitrogen fixation by legumes. Iron availability may be limited by alkaline soils, low organic matter levels, saturated soils, excessive phosphorus, or zinc deficiency. Contains 1% nitrogen derived from hydrolyzed vegetable protein and 5% chelated iron derived from iron sulfate. Apply 1–4 pints/acre (⅜–1½ oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary.
Biomin Manganese helps plants to synthesize chlorophyll and is used in electron transport during photosynthesis. Manganese availability may be limited by alkaline soils, high organic matter, excessive iron, or deficient sulfur. Contains 1% nitrogen derived from hydrolyzed vegetable protein and 5% chelated manganese derived from manganese sulfate. Apply at 1–4 pints/acre (⅜–1½ oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary.
Biomin Zinc is a component of auxin, an essential growth hormone, and is also necessary for proper root development. Adequate zinc improves cold tolerance. Zinc availability may be limited by excessive phosphorus or copper, low organic matter, or magnesium deficiency. Contains 7% zinc derived from zinc sulfate. Apply 1–4 pints per acre (⅜–1½ oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary.

Soil Amendments and Fertilizers
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. Check with your local Cooperative Extension for testing in your area, or consider our testing and recommendation service.
Soil amendments used with a program of crop rotation, composting and cover cropping can 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.
Fertilizers provide nitrogen and other nutrients in a form that is readily available to plants. Organic fertilizers can provide both an immediate boost and additional long-term fertility, feeding both the plants and the organisms that maintain soil health. We also offer soil amendments that have limited available plant nutrients but help to remineralize the soil, improve soil structure, or provide a long-term slow-release source of plant nutrients. Foliar sprays get nutrients directly to the leaves and can increase resistance to disease and to insect infestation.
Analyses provided here are those provided by the manufacturers, or, if none are available, from a Maine state lab test performed on our most recent lot: there is some variability in the nutritional analysis of natural fertilizers, so view these numbers as guides, not gospel. Fertilizers should be used as a supplement to, not a replacement for, the nutrients provided by healthy soil. Sustainability requires developing a long-term plan of cover-cropping, green manuring and composting.
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: Reviewed and approved by the Maine Organic Farmers & Gardeners Association Certification Services. Allowed for use on MOFGA-certified farms. Check with your certifier. WSDA: Listed by the Washington State Department of Agriculture’s Organic Certification division 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: Ask your certifier. Has not been reviewed by a certifier, but the active ingredient is allowed. 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.
