HUMIC ACID


Humic acid,( humic acid, abbreviated HA) is a plant and animal remains, mainly is the remains of plants, through microbial decomposition and transformation, and a series of complex earth chemical reaction process and accumulation of a class of organic matter.It is a polymer of organic acid, which is composed of an aromatic group and a variety of functional groups., have good physical activity and absorption, complexation, exchange and other functions. Humic acid is the main element of the composition of carbon, hydrogen, oxygen, nitrogen, sulfur, Is the condensation of a multivalent phenolic aromatic compounds and compounds

Widely distributed in the low level of coal, soil, water, sediment, animal manure, organic fertilizer, animal and plant residues, etc.

We often see the soil is black, because of containing humic acid (The soil is yellow if it is excluding or less with humic acid) in the low level of coal (weathered coal, lignite, peat) in humic acid content is the highest 30~80%),Followed by organic composting (about 5~20%). Coal is treated by artificial oxidation (e.g., air, ozone or nitric acid) to form a renewable humic acid.

?HUMIC ACID

In accordance with the solvent solubility and color classification, can be divided into three groups: 

(1)  dissolved in acetone or ethanol known as brown humic acid, 

(2)  insoluble in acetone part known as fulvic acid; 

(3)  dissolved in water or dilute acid part called fulvic acid.

For agriculture can be used as nutrition soil additive, rooting and additive of strong root fertilizer, soil conditioner, plant growth regulator, foliar fertilizer compound agent, cold resistant agent, drought resistant agent, compound fertilizer synergistic agent, etc. 

Humic acid fertilizer made with nitrogen and phosphorus, potassium and other elements, with fertilizer efficiency, soil improvement, stimulate crop growth, improve the quality of agricultural products and other functions.

Humic acid magnesium, humic acid zinc, humic acid urea iron respectively in soil supplemented with magnesium deficiency, iron deficiency of zinc deficiency in maize and fruit trees have good effect; humic acid and nitrofen, atrazine and other mixed use of pesticides can be improved efficacy, inhibit residue; sodium humate on treatment of Apple Tree Canker effect.

 

FULVIC ACID

FULVIC ACID

Broad spectrum plant growth regulator, promoting plant growth especially appropriate to control crop foliar stomatal openness, reduced transpiration , have an important role of drought resistance, to improve the capacity of anti-adversity, increase production and improve quality , mainly used for wheat, corn, sweet potatoes, millet, rice, cotton, peanuts, rapeseed, tobacco, sericulture, fruits, vegetables and other; can mix with some non-alkaline pesticides, and often synergistic effect.


AMINO ACID

AMINO ACID

The role of amino acids in plant growth was three:

 1) supplement source of the organic nitrogen nutrient;

 2) metal ion chelating agent. The role of amino acids with complex (chelate) metal ions,

,makes it easy to carry for the plant in elements and trace elements (calcium, magnesium, iron, manganese, zinc, copper, molybdenum, boron, selenium, etc.) to plants, increase the rate of of all kinds of nutrients by plants; 

3) enzymatic preparation. Amino acid is a promoter and catalyst for the synthesis of various enzymes in plants.and plays an important role in the metabolism of plants. However, amino acids in the soil is easy to bacterial assimilation, decomposition, So it should not be used as basic fertilizer in soil, but made foliar fertilizer, spray on the leaf let plant directly through foliar absorption of amino acids and other elements.
