Soluble Humic Acid Powder - Potassium Humates

  • $ 4.99


This organic soluble potassium humate powder is derived from leonardite and completely dissolves when added directly to fertilizer and nutrient formulations above a ph of 6.

Adding Humates is the most efficient way to increase the humus content of soil, as it is highly concentrated and much easier to apply than any other form of humic matter. Humates are highly concentrated, natural organic humus, formed through the biological breakdown of plant life over millions of years. Also, since humates are completely decomposed, they enter into no nutritional competition with plants for nutrients such as nitrogen (not the case with incompletely decomposed compost).

Typical Analysis shows 9.0 pH, 16% Soluble potash, 8% Sulfur, 48% Carbon, 28% Oxygen, 4% Hydrogen, and 80% Organic acids (55 Humic/ 25 Fulvic).

Benefits of Humates:

Increased Crop Yields -- Humates can improve root development, total leaf area and total crop yields per acre.
Increased Root Growth -- Tests have shown that root system vigor is very important to the nutrient uptake capability of plants, as well as to the plant's ability to combat disease.  In addition, plant stability is enhanced, and plants are better able to find and absorb water with a broad based root system.
Increased Chlorophyll Content -- Humic matter has been shown to increase the chlorophyll content in plants, and can prevent or correct chlorosis.
Increased Nutrient Uptake -- Humates have been shown to consistently improve the uptake of nutrients such as nitrogen, phosphorus, and iron, as well as innumerable trace elements essential for plant health.  
Improved Plant Quality -- Humates can improve the quality of fruit, vegetables, and flowers by improving their physical appearance, and in the case of food crops, their nutritional value.  Cereal crops have shown more balanced amino acid content, and higher protein content.  All of this can enhance their worth in the marketplace.
Enhanced Natural Defenses -- Many toxins are inhibited or neutralized directly by bonding interactions with humic acids.  Plants which are healthy and receive all of their required nutrients are better able to combat disease and pests.
Improved Soil Structure -- Humus combines with clay minerals to form structural units called aggregates which help to stabilize the soil and increase its permeability to water and gaseous exchanges. The use of humates can prevent soil cracking, which exposes roots to the air and can cause crops to burn in severe heat conditions and improves overall soil structure to help defend against erosion.
Improved Water Retention -- Humates can hold up to 20 times their weight in water.  By enhancing the soil's ability to retain water, humate usage can reduce the need for crop irrigation.  This can be especially helpful with sandy soils, and contributes a large measure of drought resistance to crops.
Differing Soil pH --Humates create an environment where plants are able to grow healthy in a wider pH range.

 

Humic Acid Application Guidelines

Thoroughly mix into a diluted solution for 10-15 minutes before use.

  • GENERAL USE: To formulate a 15% minimum liquid solution of humates, dissolve 2 lb. per gallon. Test compatibility prior to use. Plants need to be just past the seedling stage - about 25% coverage of the ground before the first application. Second application is usually just before flowering, or just before the onset of the reproductive stage of the crop. The 3rd application would be early in the grain fill or fruit/vegetable sizing stage. 

  • SPRAY APPLICATION: It is best to dilute by at least a factor of 10, preferably 15 or higher for spray application to obtain full coverage.

  • GARDEN VEGETABLES & STRAWBERRIES: Dissolve 1 lb. powder per acre per treatment; 3 treatments per year in irrigation water.

  • DRIP IRRIGATION: Dissolve 3 lbs. powder per acre; weekly treatments. 

  • SOIL CONDITIONER: Dissolve 1 lb. powder per acre to promote absorption. 

Can be applied to all crops and compost.
