Pure Humic Acids – An Essential Component For Plant Growth 500gm (Black)

Humic acids are an excellent natural and 100% organic way to provide plants and soil with a dose of essential nutrients and trace elements. Humic acids is a bio-stimulant that is derived from leonardite shale and is among the most concentrated organic material available.

Humic acids are not fertilizers. They act as a bio-stimulant for the plant. Humic acids enhance plant growth particularly biomass production and fertility of the soil. As humic acids are completely decomposed, they do not enter into nutritional competition with plants for nutrients such as for nitrogen.

Humic acids are complex organic molecules that are formed by the breakdown of organic matter. Humic acid influences soil fertility through its effect on the water-holding capacity of the soil. Humic acids make important contributions to soil stability and soil fertility leading to exceptional plant growth and micronutrient uptake.

Humic acids is an internationally recognized safety, green, effective and natural conditioner.

By supplying the soil with sufficient humic acid, we help to bind cations (positively charged elements). The ability to chelate positively charged multivalent ions (Mg, Ca, Fe and other “trace minerals” of value to plants) is probably the most important role of humic acids, with respect to your soil. By chelating the ions, humic acids facilitates the uptake of the ions by means of several mechanisms, one of which is preventing their precipitation (leaching through the soil). Another is the direct and positive influence on their bio-availability. It can also detoxify the soil of heavy metals. Research has shown that heavy metals can be “locked up” with the addition of humic acids.

Humic acids increases nutrient uptake, drought tolerance, and seed germination. It increases the microbial activity in the soil, making it an excellent root stimulator. Humic acids increases the availability of nutrients in fertilizers and in those already existing in your soil. It will help to aerate the soil from the inside. It will also help to lower the pH of the soil to a more neutral level and will flush high levels of salts out of the root zone, all of which will help to promote better plant health and growth.

• Humic acids has a high base exchange capacity and rich in both organic and mineral substances essential to plant growth.
• Humic Acids can loose topsoil, destroy the accumulation of salt, reduce salt content in the topsoil.
• Bind available insoluble metal ions, oxides and hydroxides, slowly releasing them to roots.
• Improve the utilization of nitrogen fertilizer.
• Enhances phosphate & Potash utilization of plants.
• Regulate soil environment pH value.
• Prevent water and nutrients losses in light, sandy soils and promote soil aggregate structure.
• Increases crop yield.

In terms of aquatic plants, it enhance photosynthesis, provide a variety of nutrients needed for plants and quantitative slow release of nutrients for the plants to absorb. It can also absorb ammonia and hydrogen sulfide and other substances in the water to improve water quality.

Before put the new soil into the pot, add 3 – 5% of the Humic Acids powder into the total amount of the medium mixing (Manure + Compound fertilizer + Humic Acids + Others ingredients) and blend evenly. If you already have plants in pots, dig 2 – 3 cm of the soil surface and apply 50 – 100g Humic acids powder per pot then normal watering.

Or you can also add 2 – 3g Humic acids powder into 1L water and stir evenly then directly irrigating the roots, 1 – 2L water per pot depend pot size. Application frequency: 2 – 3 times per month.

Use 200 – 400 grams Humic Acids Powder per square meter of soil blending, as base fertilizer, improved soil, slow release of nutrients. Application frequency: once a year.

Use 10 – 40 grams Humic Acids Powder per square meter. Application frequency: 2 – 3 times a month.

At the bottom of the aquarium, laying around 1 – 2 cm in Humic Acid powder, then covered with a thin plastic mesh. Finally, laying a layer of sand. The fertility can be maintained around 3 months. Or put the Humic Acid powder into fine cotton bag or plastic bag for easy to replace.

• Avoid mixing with strong acids, alkaline substances and oxidants.
• Avoid use under bright sun light.
• Sealed and keep in dry place at room temperature.
• Keep out of children reach.
