SPECTRA®
Potassium High-Carbon Humic Acid Solution
Potassium High-Carbon Humic Acid Solution
Increases Nutrient Absorption
Spectra enhances nutrient uptake by transforming vitamins and minerals into organic, ionic forms that plants can easily absorb and utilize.
Improves Fertilizer Efficiency
By facilitating nutrient transport into plant foliage and roots, Spectra optimizes fertilizer effectiveness. Its low-molecular-weight formulation improves mobility through cell walls to key growth points.
Improves Tank Mix Compatibility
Spectra is compatible with foliar applications of non-selective herbicides, fungicides, insecticides, and other pesticides. It also improves the tank mix compatibility of fertilizer and pesticide combinations.
Detoxifies Pollutants
Fulvic acid plays an important role in forming new species of metal ions, binding with organic pollutants such as pesticides and herbicides, and catalyzing the breakdown of toxic pollutants.
Helps Transport Nutrients
Spectra also helps transport nutrients into plant foliage and roots. Its highly active, low-molecular-weight formulation improves the mobility of solutions through cell walls to plant growth points, resulting in a more productive and impactful application.
Non-Plant Food Ingredients
Fulvic Acid: ……………………………………………………………….20%
Other Ingredients: ………………………………………………..80%
Total: …………………………………………………………………………..100%
Foliar Applications
Spectra may be blended with any compatible fertilizers and foliar sprays applied to all row crops, field crops, forage crops, feed crops, vegetable crops, trees, nut trees, vines, lawns, gardens, and ornamentals. Spectra can be foliar-applied at up to 12 ounces per acre per application. Apply at least 2 oz. per acre in all foliar applications. Dilute KaPre Spectra in at least 20 gallons of water.
With Herbicides
Apply Spectra at rates of 2 – 12 fl. oz. per acre with NON-SELECTIVE herbicides only.
Transplanting and Cuttings
Blend 2 – 4 fl. oz. of Spectra per 20 gal. of solution.
Cool Season Grasses
Include Spectra with all foliar nutrient applications at a rate of 2 fl. oz. per 25 gal. of spray solution.
Use Spectra alone to reduce plant stress before, during or after stressful periods at a rate of 0.5 fl. oz. per 1,000 ft2Â or 2 – 6 fl. oz. per 25 gal. of spray solution.
Trees, Shrubs, Woody Ornamentals and Bedding Plants
Include Spectra with all foliar nutrient applications at a rate of 2 fl. oz. per 25 gal. of spray solution.
Use Spectra alone to reduce plant stress before, during or after stressful periods at a rate of 0.25 fl. oz. per 1,000 ft2Â or 2 – 6 fl. oz. per 25 gal. of spray solution.
Warm Season Grasses and Ornamentals
Inject into irrigation or broadcast spray at a rate of 10 – 20 fl. oz. per acre 1 to 3 times during the growing season.
Mix with root injections at a rate of 4 – 6 fl. oz. per 10 gal. of injection solution.
