In soil humic acid helps improve water retention, increases soils over all structure, and help to maintain soil stability. Humic acids readily form salts with inorganic trace minerals in a form that can be more easily utilized by plants.
Humic acids promote vigor, disease resistance and root development in plants. These increases result in faster growth. The acids assist roots by increasing soil permeability, increasing water retention, reducing water evaporation, and promoting the growth of beneficial microbial colonies in the root zone. The creation of a healthy, microbial-active root zone environment creates stronger plants that uptake nutrients better.
In hydroponics helps the environment humic acid supplementation offers many of the same benefits to plants that it does in a soil culture. Because hydroponics is performed in an enclosed environment it is possible to specifically target plants with a minimum of waste.
By adding humic acid in hydroponic preparations, to the nutrient reservoir will increase the efficacy of the nutrients, making both micro and macro nutrients more readily available to the root zone. Humic acid’s high cation capacity serves as a chelator which helps plants better assimilate all the nutrients in the solution. The chelation process helps make and keep nutrients readily available to be used by plants as needed.
Also humic acid by is self will break down ammoniacal nitrogen
Environmental stresses can cause irreparable damage to plants; stunting or delaying growth, prohibiting flower production or even causing death. Free radical molecules result from stress such as high heat or temperature fluctuations, too high humidity, pesticide applications and nutrient deficiencies or toxicities.
The bio-stimulant activity of humic acid produces anti-oxidants that combat these free radicals making plants more resistant to these and other environmental stresses. Humic acid remains in the cells providing ongoing protection.
One of the organic compounds in humic acid is carbon which manufactures sugars in plants. Sugars are especially important during flowering as plants require an increased amount of carbohydrate to produce bud. The carbohydrate infusion delivered in humic acid will also organically enhance flavor, color and aroma of your buds.
Beneficial bacteria and fungi reproduction created in the presence of humic acid biologically increase plant growth. The microbial activity produced by these bacteria and fungi are excellent root simulators. Humic acid has also been shown to lower pH to a more neutral level helping with the availability of nutrients. All this translates into healthier, stronger more pest resistant plants.
Humic acid is an environmentally safe bio-stimulant that can be used throughout the entire growth cycle. The addition of humic acid black to a high quality nutrient regimen will result in superior quality bud production whether it is through soil or hydroponic cultivation.
Also Humic acid is a great defense to keep pathogens at bay the study done at the university of California and Mexico on avocado plants showed a decrease of sick plants in both controls by 43% vs the control that did not use it at all.
Another reason for Humic Acid:
A study at Australia’s Urban Water Research Association concluded: You can neutralize chloramine by mixing 1 teaspoon of humic acid per 100 gallons of water.
