The Differences Between Potassium Humate & Potassium Fulvate
Potassium fulvate is similar to potassium humate.
The only difference between them is that the raw material used to produce potassium fulvate is rich in fulvic acid.
The water-soluble humic acid in potassium humate has a polymer structure.
Its good chelating property causes the humic acid to slowly form a flocculating substance when it encounters such metal ions as calcium or magnesium in water, and finally forms a precipitate.
The water used in agriculture, generally well water, river water and lake water, are mostly hard water, containing a large amount of high-valent metal ions.
This will inevitably reduce fertilizer efficiency.
Having better activity and a smaller molecular chain, fulvic acid in potassium fulvic acid can be dissolved in acid, water as well as alkali solution and can maintain a state of stability.
No precipitation, no flocculation, no delamination.
According to our test, potassium fulvate can maintain a stable state in a solution of pH 2-14.
