Humic acid is a naturally occurring component of soil organic matter and it plays a vital role in plant growth. Regular application of humic acid for lawns has been shown to facilitate the growth of turfgrass and other garden plants. Impressively, it does not come with any of the potentially devastating environmental effects of inorganic fertilizers. It is no surprise, therefore, that there is an increased interest in humic acid for lawns. But how exactly can humic acid help plants grow?
What does humic acid do?
In an age of increasing advocacy for sustainable gardening, people are turning towards organic supplements in a bid to curb the widespread use of harmful inorganic fertilizers. Numerous scientific inquests have been launched to investigate the exact role of humic acid in plant growth and the results have been nothing short of astonishing. It has been shown that humic acid is capable of improving soil structure, soil chemistry and microbial profile. If anything, these studies support the assertion that humic acid is not just another rave of the moment. It’s role is too important to be ignored and it would soon become a mainstay in organic gardening. Below are some of the benefits of humic acid to your lawn and soil.
Effects of humic acid lawns on soil structure
- Humic acid prevents the loss of water in sandy and other light soil types. In compact soils, humic acid can help remove water retention and soil aeration, making the soil more suited for cultivation.
- Humic acid increases the ability of the colloids present in the soil to combine with each other. This prevents soil erosion or surface water runoff and soil cracking.
- Humic acid can also facilitate the absorption of energy from the sun by plants. It is thought to achieve this due through its soil darkening property.
- By increasing the water holding capacity of a given soil sample, humic acid for lawns could prove valuable in areas with minimal rainfall or during periods of drought.
Effects of humic acid lawns on the nutrient/chemical profile of the soil
- Humic acid greatly improves the buffering properties of any soil sample. The presence of alkaline soluble and acid soluble components in humic acid for lawns makes it capable of neutralizing soil pH.
- Humic acid prevents the leaching of soil nutrients by retaining water-insoluble nutrients around the root zone of plants.
- Humic acid has excellent chelating properties. Thus, it facilitates the uptake of essential metal ions by the root of plants.
- Humic acid enhances the conversion of essential elements such as Nitrogen, Phosphorus, Potassium, Zinc, Iron, etc, into forms that can be readily absorbed by plants.
- It decelerates the reaction of phosphorus with cations such as Iron, Magnesium, Calcium, etc. Consequently, plants are better able to absorb phosphorus as well as these cations.
- Its chelating properties could also prove useful in trapping toxic substances such as heavy metals in the soil.
- Humic acid facilitates the breakdown of calcium carbonate, liberating carbon dioxide in the process. The liberated CO2 is all important in photosynthesis
- Humic acid boasts impressive cation exchange properties, promoting the liberation of cations in the soil and their availability to plants.
Effects of humic acid lawns on soil microorganisms and plant biology
- Humic acid is capable of increasing the production of plant enzymes and stimulating their activity
- The water retention properties help provide a moist environment for soil microbes to thrive
- It enhances the binding of nutrients to the roots of plants, thereby increasing root respiration
- Humic acid has also been shown to stimulate vertical root growth, helping plants develop larger root systems and ultimately making them stronger.
- Humic acid is known to aid photosynthesis and the effects are visible in the quality of yields.
How do you apply humic acid for lawns?
If you want to get the best out of humic acid, you should think of it as a vaccine. You don’t vaccinate after a disease outbreak; same way you don’t apply humic acid for lawns when you notice your grasses are already feeling the stress. You should have a regular schedule for applying humic acid and other nutrients on your soil. This keeps your lawn healthy all year round and you’ll discover the plants on your treated soil would perform much better than the plants on untreated soil.
Applying humic acid for lawns as a foliar spray produces the best results. You should also remember humic acid works best in synergy with other bionutrients. Rather than applying humic acid alone, you should combine it with other plant nutrients in order to derive maximal efficiency.
When applied as a foliar spray, humic acid increases the rate at which your lawn plants will absorb fertilizer. Many farmers also report that they are able to cut their insecticide and herbicide rates by applying humic acid. In the long run, incorporating humic acid into your bionutrient application schedule could help save cost.
Why you should go for Organic Water Extracted Humic Acid®
Once you are convinced on the need to use humic acid for your lawn, you’ll have to choose the best humic acid product for you. Organic Water Extracted Humic Acid® should be the first name that would come to mind. The product has been carefully formulated to produce very high yields while applying less fertilizer. It promises to deliver all the benefits you hope to get from your humic acid lawn and much more.
The Organic Water Extracted Humic Acid® comes as a concentrated mixture. One gallon of humic acid can be mixed with up to 10 gallons of water, producing enough humic acid to cater for up to 9 acres. You could also incorporate the product into your irrigation system in order to facilitate effective and even distribution. Another unique benefit of humic acid is that it is safe to mix with anything. Fertilizers, herbicides, insecticides, turf-protection products, etc. all mix well with humic acid for lawns.
