1. Stimulate plant root growth and nutrient absorption
The stimulating effect of potassium fulvic acid on plant root growth is the initial driving force for its promoting effect on plant growth. In addition, potassium fulvicate can stimulate the negative regulatory factors of Arabidopsis root hair cells to reduce their expression, promote the remodeling of root morphology, and increase the root area for absorbing nutrients, thereby achieving a growth-promoting effect. Potassium fulvicate can also promote the absorption of nutrients by plant roots, mainly by promoting the absorption of nitrate, and potassium fulvicate can also be absorbed by plants as a nutrient.
2. Enhance plant stress resistance
Potassium fulvic acid can regulate the physiological and ecological changes of plants and enhance plant stress resistance.
3. Improve nutrient utilization efficiency of soil and fertilizers
Potassium fulvicate is a green mineral element active potassium fertilizer. It has a series of functions that can directly or indirectly promote plant growth. One of them is to improve the nutrient utilization efficiency of soil and fertilizers.
4. Regulate the activity of soil microorganisms and enzymes
The humic acid contained in potassium fulvic acid is an important component of soil humus. It has a stable carbon form and plays a key regulatory role in the quantity and diversity of soil microorganisms. Potassium fulvicate can also improve the soil by regulating soil enzyme activity, providing favorable conditions for the growth of plant roots and the preservation of fertilizer nutrients.
