Potassium Humate


Humic Acid is a structure less colloidal material that has gone through decomposition. Humic Acid is derived mainly from plant residue. Humic Acids are highly biodegraded and compressed remains of ancient plant and animal materials. Simply put, Humic Acids are highly decomposed organic materials that have fossilized over a period of millions of years. Humic Acids are also referred to as "humic substances" and are used as soil conditioners, soil supplements, and fertilizer amendments.

Humic acid increases the water holding capacity of soils. Humic Acid also carries with it hormones and vitamins which promote germination as well as greater plant growth. Humic Acid is a virtual storehouse of not only micro-nutrients, but also, holds the essential macro-nutrients nitrogen, phosphate, and potassium. The most important and bio-chemically active group of the many decomposed products of soil organic matter is the alkali soluble substance called humic acid.

Humate is defined as the salts of Humic Acids. It must also go through many chemical changes prior to entering the plant system. Potassium Humate enhances the overall performance of the fertilizers to a point that an actual reduction of basic N-P-K per 1,000 square feet may be appropriate over time; enhances the development of root systems; enhances success of seed germination and overall plant development; enhances overall plant health, resistance to stress, and appearance.

Benefits of Humic Acid

In our process, we convert Humic Acid into a more active and fast action potassium salt of Humic acid i.e., Potassium Humate. Potassium Humates enhance nutrient uptake, improve soil structure, and increase the yield and quality of various crops. Potassium Humate promotes the conversion of a number of elements into forms available to the plants. It is well documented that the availability of P2O5 is increased in the presence of humic acids. Potassium Humate increases the permeability of plant membranes so promoting the uptake of nutrients

Humic acids affect the release of plant nutrients, especially nitrogen through slow decomposition by organisms. The soil humus may also contain or release plant growth substances and support the growth of organisms. Potassium Humate possesses very high ion-exchange capacity. This property results in better utilization of fertilizers by retention of the nutrients in the root zones.

Mode of Action

  • Potassium Humate increases the holding capacity or retention ability of the soil for holding water with extended use b
  • Potassium Humate increases the efficacy of fertilizer, by preventing excessive leaching away from the root zone and ultimately releasing it to the root zone as needed
  • Potassium Humate helps to reduce soil erosion by increasing cohesive forces of very fine soil particles
  • Potassium Humate changes the physical and mechanical properties of the soil in structure, color, consistency, and moisture holding capacity to a very great degree as the organic matter increases
  • Potassium Humate increases the permeability of plant membranes, enhancing the uptake of nutrients more efficiently
  • Potassium Humate improves the soil environment to it’s optimum, which is needed for the uninterrupted growth of various groups of beneficial micro-organisms.
  • Buffers pH problems, allowing plants to adapt better, until the pH can be corrected.
  • Decreases stress deterioration, until it can be corrected.
  • Increases the germination capacity of seed via the improved CEC levels of the soil.
