Humic acid is a soil conditioner that acts as a bio-catalyst and bio-stimulant. It greatly increases plant biomass production by creating a favorable physical and chemical environment for root growth. It is a mined product from Leonardite stone deposits. Leonardite is a pre-historic deposit of decomposed plant and animal tissues that are not yet coal. The largest deposits are in the Dakotas and New Mexico.
Humic acid bonds to the soil and gives the soil a better structure. Water retention is improved due to the increased porosity of the soil profile. It helps break up overly dense soils.
This substance also has chemical benefits in the soil. It helps buffer the Ph, enhances nitrogen and micronutrient uptake of the plants and chelates nitrogen and other micronutrients into a form the plant can use. It also reacts with calcium, iron, and Magnesium and limits the phosphorous reaction with those nutrients thus freeing up phosphorous that the plant can use it. Phosphorous is very important in root production.
The bio-stimulant properties include increasing cell division, thickens cell walls, increases root growth, stimulates enzymes, and acts as an organic catalyst.
We apply Humic acid as part of a product called Turf Fuel xChange. The product contains Humic acid, salicylic acid, and Sea Kelp.
