Humic acid is a complex mixture of natural organic macromolecular compounds that are widely found in nature, with the highest concentration in soil. It is a heterogeneous complex mixture with diverse physical and chemical properties, characterized by a polydisperse molecular weight. Humic acid is a natural, high molecular weight, yellow to black, amorphous, colloidal substance composed of aliphatic and aromatic organic polyelectrolytes. Due to its complex nature, it cannot be represented by a single chemical structural formula.

308067-45-0 Usage

Uses

Used in Agriculture:
Humic acid is used as a growth promoter for plants, enhancing crop yield. It acts as a close friend to inorganic fertilizers, improving their effectiveness and efficiency in various ways:
As a slow-release agent and stabilizer for nitrogen fertilizers, humic acid helps in the controlled release of nitrogen, ensuring a steady supply for plant growth.
As a synergist for phosphate fertilizers, humic acid works in conjunction with phosphates to enhance their availability and uptake by plants, thus improving overall nutrient utilization.
As a protective agent for potassium fertilizers, humic acid helps in preserving the availability and effectiveness of potassium, which is crucial for various plant functions.
Humic acid also has a significant synergistic effect on chemical fertilizers, enhancing their overall performance and contributing to improved soil health and plant growth.

Check Digit Verification of cas no

The CAS Registry Mumber 308067-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,0,6 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 308067-45:
(8*3)+(7*0)+(6*8)+(5*0)+(4*6)+(3*7)+(2*4)+(1*5)=130
130 % 10 = 0
So 308067-45-0 is a valid CAS Registry Number.
