Humic compounds include both humic and fulvic acids (along with humin). However, there are a few significant variances that affect their advantages and the most effective ways to use them. In essence, they differ in terms of acidity, molecular weight, degree of polymerization, carbon and oxygen concentration, and color. They work in tandem to help boost plant help and increase crop yields.
More about Humic Acids
The precise make-up of humic molecules varies depending on the source. In acidic environments, they are not soluble in water, but they are soluble in alkaline solutions. Humic acids function best in soil, where they easily liberate plant nutrients from their bonds and make them accessible to plants for uptake. Additionally, they chelate dangerous metals to keep them from entering the plant. Additionally, they promote soil microbial activity, improve water retention, and promote root and shoot growth.
More about Fulvic Acids
Unlike humic acids, which are only soluble in alkaline solutions, they are soluble in water at all pH levels. Fulvic acids come in two different forms: free-form fulvic acids and fulvates, which are molecules attached to minerals. Mostly carbon, hydrogen, oxygen, and nitrogen make up fulvic acids.
Fulvic acids' ability to bind to nutrients and transmit those nutrients into plants is its main advantage. Fulvic acids are actually the most potent carbon-containing chelating agent yet discovered.
