The Function of Potassium Humate in Planting Industry BY: Lydia
Definition of potassium humate for agricultural use: Humate extracted from weathered coal, lignite, peat and other organic minerals using potassium hydroxide as raw materials is agricultural potassium humate.

1.Regulating acid and alkalinity: Humic acid has a strong cation adsorption capacity, which will adsorb alkaline cations (such as H+, K+, Na+) in the soil around it, thereby reducing the Ph value of alkaline soil. At the same time, potassium humate itself is alkaline, and can react with acidic ions in the soil to produce acid-base neutralization reactions, thereby increasing the Ph value of acidic soil. That is, potassium humate can adjust acidity when it encounters acid and adjust alkali when it encounters alkali, playing a two-way regulatory role. It can greatly improve the soil's buffering of acidic and alkaline fertilizers.
2.Activating the soil: Potassium humate has a strong cation exchange capacity and can promote the movement of nutrients in the soil. It provides carbon nutrition to the soil and promotes the activity of beneficial microorganisms in the soil.
3.Enhanced slow release: Humic acid has an adsorption effect on nitrogen and potassium, preventing nutrient loss and improving the slow release of fertilizers.
4.Loosening the soil: Humic acid can promote the formation of soil granular structure, reduce soil density, increase soil dissolved oxygen content, air permeability, and make the soil soft.
5.Water retention: Humic acid has the function of adsorbing water molecules, improving the soil's ability to retain water and fertilizer.
6.Rooting: Humic acid can release phosphorus fixed by trace elements in the soil, improve phosphorus utilization, and promote crop rooting.
7.Improve stress resistance: Improve crop respiration and photosynthesis, enhance stress resistance, such as drought resistance, cold resistance, disease resistance, etc.
8. Fruit swelling and coloring: Humic acid can promote potassium absorption, improve soil ecology, and promote crop absorption of nutrients, thereby promoting fruit swelling and coloring, and increasing the sweetness of fruits.
