What is humic acid made from?
Humic acid is derived from leonardite shale and is among the most concentrated organic material available. Elemental analysis of humic acid has shown it to consist largely of carbon and oxygen (about 50% and 40% respectively).
What is meant by humic acid?
Humic acids are the organic substances that coagulate when the strong-base extract is acidified while fulvic acids are the organic substances that remain soluble when the strong-base extract is acidified. From: Soil and Environmental Chemistry (Second Edition), 2017.
What is humic acid used for?
Overview. Humic acid is a chemical produced by decaying plants. People have used it to make medicine. People sometimes use humic acid to stimulate the immune system, for infections, and many other purposes, but there is no good scientific evidence to support any use.
What is humic acid formula?
Humic acid has the average chemical formula C187H186O89N9S1 and is insoluble in strong acid (pH = 1).
How is humic acid prepared?
The classical method for obtaining humic acid is by extracting the humic acid source with an aqueous solution of sodium hydroxide. Humates are dissolved in the extracting solution and separated from insoluble tailings. The extract is then acidified and the humic acid is precipitated.
What is humic fertilizer?
Humic acid is a mixture of natural organic macromolecular compounds, which exists in all soils, plants and animals,and have been widely used in agricultural production in recent years due to their unique physiological functions.
What is humic acid fertilizer?
Humic acid is 100% Organic Liquid Fertilizer. Humic Acid is extracted from compressed, ancient plant matter in the form of leonardite (a soft brown coal). It is an ideal additive to boost bio-activity and improve the performance of compost, soil structure and plant nutrients intake.
Is humic acid a fertilizer?
Humic acids generally aren’t considered a fertilizer. Whereas fertilizers provide specific nutrients to plants, humic (and fulvic) acids increase the availability and uptake of those nutrients, and improve the overall growing environment.
Is humic acid a organic fertilizer?
How is humic acid used in agriculture?
Humic acid buffers soil pH to 5.5 to 7.5 levels which is ideal for plant development and nutrients absorption. Thus acting as a natural chelator, they help plant roots to absorb nutrients more efficiently to create long term positive effect on soil quality and productivity.
How do you make humic acid solution?
Steps to Make Humic Acid Yourself
- Add some hydrochloric acid to the supernatant till the pH value of this solvent mixture is 1.0.
- Let this suspension stand for about 14 hours and then separate the resultant powdered humic acid (precipitate) from the fulvic acid via centrifugation as decantation is no longer possible.
Can I mix humic acid with NPK?
It has Macro Nutrients Nitrogen Phosphorous Potassium : (20%) In NPK 20 20 20 – Concentrated Micronutrients which gives proper controlled growth. along with organic humic acid which increases Root density. The combination enhances flowering fruit vegetable of plant. These 3 together gives TREMENDOUS results on field.
Can I make my own humic acid?
Steps to Make Humic Acid Yourself. You can either extract humic acid from a humus rich soil sample, from peat moss or from humic compost. If you regularly add humic compost to your garden then sourcing humic acid from both humus laden soil or the organic compost would be easy, though quite tedious.
Does humic acid dissolved in water?
Humic acid is insoluble in water at any PH. You can dissolve the acid in Basic solution such as NaOH and bring down the pH to required level by slowly adding acid solution.
