Soluble Humic Acid Powder - Potassium Humates

  • Sale
  • $ 5.50

This soluble humic acid powder is a concentrated source of humic acids which makes a liquid solution containing up to 12% Humic Acid (by weight). It is OMRI listed for organic use. Solution can be mixed with liquid fertilizers having a pH of 5.5 or higher. This adds organic material in liquid form with a high percentage of humic/fulvic acids to your plants to enhance uptake of nutrients. 

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.

  • FIELD CROPS FOLIAR: Using 2-3 lbs. per acre as a foliar application, 2-3 times per growing season is recommended for row crops and forages. 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.

  • HYDROPONICS: Use 1/16 - 1/4 teaspoon per gallon of water. 

  • GENERAL FOLIAR APPLICATION: Make a liquid solution using 1/4 - 1 teaspoon per gallon of water and spray leaves until wet. 

  • LAWNS: Make a liquid solution using 1 Tablespoon per 100 sq. feet for new lawns or seedbeds and 1 Tablespoon per 300 sq. feet for established lawns.
