Micronutrients Liquid Mineral

Micronutrients Liquid Mineral

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. We were thrilled to find a line of OMRI-Listed® liquid micronutrient products in package sizing that makes sense for home gardeners and small-scale market growers! 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.

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.

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.

Iron 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 5% chelated iron derived from ferrous sulfate. Apply 1–4 pints/acre (⅜–1½ oz/1000 sq ft) diluted 100:1. Repeat in 1–3 weeks if necessary.

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.

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.

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.
