Humic acid is extracted from soil and fertilizer is extracted from basic characteristics of humic acid. At present, facing the safety problems of soil, fertilizer, grain and environment, we must adjust the development direction of fertilizer industry in time and build a new relationship of “harmony between soil and fertilizer”.
Humic acid, as the “nutrient” of soil nutrients, is a bridge link connecting soil fertilizer plant nutrition. Under the guidance of humic acid in plant mineral nutrition, how can we master the technical requirements of humic acid?
1、 Humic acid + macronutrients
Group structure efficiency
The combination of humic acid and nitrogen fertilizer can reduce the loss of nitrogen and improve the utilization rate of nitrogen; Humic acid and phosphate fertilizer can activate phosphorus and improve the utilization rate of phosphate fertilizer in season; Humic acid and potassium fertilizer can activate potassium and promote the absorption of potassium by crops
Adduct
Humic acid + nitrogen = humic acid nitrogen, Urea Humic acid, and ammonium humic acid; Humic acid + phosphorus = humic acid phosphate; Humic acid + potassium = potassium humic acid fertilizer;
2、 Humic acid + nutrient content
Group structure efficiency
Humic acid can store, protect and increase efficiency of some elements by adsorption, chelation, complexation and ion exchange, reduce the fixed nutrient content of soil, improve nutrient utilization rate and promote crop absorption.

Humic acid + calcium = calcium humic acid fertilizer; Humic acid + magnesium = magnesium humate fertilizer; Humic acid + sulfur = humic acid sulfur fertilizer;
3、 Humic acid + micronutrient
Group structure efficiency
Humic acid, as chelating agent and surfactant, can improve the fertilizer efficiency of trace elements and promote the absorption of trace elements by crops. At the same time, humic acid and fulvic acid are used as chelating agents, and their cost is better than other types of products.
Adduct
Humic acid + iron = iron humic acid fertilizer; Humic acid + manganese = manganous humic acid fertilizer; Humic acid + zinc = zinc humic acid fertilizer;
4、 Humic acid + beneficial elements
Group structure efficiency
Humic acid can activate and coordinate beneficial elements through adsorption, network (chelation), oxidation-reduction, etc., so as to improve the fertilizer efficiency of beneficial elements and promote the absorption of beneficial elements by crops.
Humic acid + silicon = humic acid silicon fertilizer; Humic acid + selenium = humic acid selenium fertilizer; Humic acid + Sodium = sodium humic acid fertilizer;
5、 Humic acid + beneficial microorganism
Group structure efficiency
Humic acid and beneficial microorganism are combined. On the one hand, humic acid can promote the growth and reproduction of microorganisms and enhance the activity of beneficial microorganisms; On the contrary, it can promote the further decomposition and synthesis of humic acid, which is beneficial to the absorption and growth of plants. The two combine and complement each other.
Humic acid + nitrogen fixing bacteria = humic acid nitrogen fixation; Humic acid + phosphate dissolving bacteria = humic acid phosphate fertilizer; Humic acid + potassium solution = humic acid solution potassium fertilizer;
Humic acid is added to the land and grows in the countryside, which is conducive to promoting the construction of “beautiful countryside and green countryside”, and also enables humic acid to have its own home.
