TeraVita LC-10 Plus 7 is a liquid concentrate that contains 10% humic acid PLUS seven important micronutrients of plant health. Micronutrients include Boron, Cobalt, Copper. Iron, Manganese, Molybdenum and Zinc. Humic acid is not a plant food, but may increase the availability of micronutrients to plants. TeraVita LC-10 Plus 7 is compatible with a majority of companion materials, but it is preferred that this product be applied by itself. This product should not be mixed with calcium or magnesium based materials (such as calcium nitrate) or materials containing high levels of soluble micronutrients. Adding these materials could make portions of TeraVita LC-10 Plus 7 less available to the plant. Note: This product is not compatible with materials that have a pH lower than 4.0. As with any product, we recommend a jar test when adding companion material to TeraVita LC-10 Plus 7 for the first time. Apply directly to soil, in drip irrigation, and as a foliar spray. Standard application rates are between 1-2 gallons per acre per year. For severe micronutrient deficiencies up to 3-5 gallons per acre per year. Most effective when applied in small dosages as a foliar spray at 0.5 -1 gal per acre per application. Ideal foliar use indicates 1 quart per acre every 2-4 weeks with a spray concentration ranging between 1 oz./ per gallon of spray and 1 ounce per 10 gallons of spray. Ships in a 32 oz. jug.
