Lets have a look on the wide range of Humic Acid which increases the water infiltration and water-holding capacity of the soil. This acid greatly improves the soil, increases plant root growth and metabolism, enhances seed germination, and helps plants deal with environmental stresses. This acid chemically changes the fixation properties of the soil. Humic Acid is available in some varieties such as Liquid Humic Acid, Eagle Black Humic Granules, Eagle Granules Humic Amino Shiny Balls, and much more. This also removes odours in slurry and compost piles, and keep irrigation lines clean. This acid also improves and optimizes the uptake of nutrients and water by plants as well as increases buffering properties of soil.
