How to use Humic Acids
1. What is humic acid? Humic role?
Humic acid is black or brown amorphous organic polymer, insoluble in water, but with colloidal properties,
can improve soil structure and improve soil fertility; with chelation, can improve nutrient reactive phosphorus,
potassium and trace elements and fertilizer utilization; also promote crop growth, improve the resistance
of crops. In addition, complex NPK with humic acid on other elements also have a sustained effect.

2. What is humic acid fertilizer?
Humic acid fertilizer containing humic acid fertilizer is the general term for a variety of multi-peat,
leonardite as the main raw material, through a certain process to extract, concentrate or become
water-soluble fertilizer containing nutrients are made. For example, rich in humic materials made by
adding sodium hydroxide, sodium humic acid; sulfuric acid made from humic acid; humic acid-containing
feedstock into nitric acid into a nitro humic acid; nitrate or potassium hydroxide made base humic acid
potassium; or made by the ammoniated ammonium humic acid; humic acid is added in the production
of fertilizer or join in the production of nutrient-based fertilizer and humus preparation humic acid
3. Humic acid fertilizer application methods and standards?
Currently, the humic acid fertilizer are constantly in development, quality control of its products, mostly
industry and local standards, application methods vary by product.
Water-soluble fertilizer containing humic acid is add the appropriate amount of humic acid NPK, or liquid
or solid fertilizer made of trace elements. Industry technical standards (NY1106-2006) provides that humic
acid content of humic acid fertilizer containing a large number of elements of type Ⅰ and type Ⅱ solid
product of not less than 3% and 4%, NPK total content of not less than 35% and 20%; humic acid content
of the liquid products were not less than 30g / L and 40g / L, total NPK content of not less than 350g / L
and 200g / L. Humic acid and trace element content of humic acid fertilizer containing trace elements
in type of not less than 3% and 6%. Low levels of water-soluble substances, solid and liquid products
content shall not exceed 5.0% and 50g / L, respectively.
On the application method, water-soluble solid or liquid products mainly for fertilizer, seed fertilizer or
soaking, Baptist roots.
