Potassium humate Application in agriculture
Potassium humate Application in agriculture to specify Potassium humate can be dissolved in both dilute alkali solution and acid and water components;
Potassium humate fixes nitrogen: Nitrogen is applied to the soil and is easily volatilized into the atmosphere or lost to the river with water and soil. The Humic acid can adsorb nitrogen in the soil, reduce its volatilization and loss, and improve the utilization rate.
Potassium humate dissolves phosphorus: Phosphorus is applied to the soil and is easily fixed by the soil. Humic acid can liberate phosphorus from the soil by chelation with phosphorus, which is used for plant absorption and improves phosphorus utilization.
Potassium humate activates potassium: Potassium, which is applied to the soil, is mostly in the form of potassium salts and cannot be directly absorbed by crops. The Humic acid can convert the poorly soluble potassium into soluble potassium through the ion exchange function, increase the effective potassium in the soil, and improve the utilization of potassium.
Potassium humate micro-fertilizer: Humic acid can chelate reaction with poorly soluble trace elements, and produce humic acid trace element chelate which is well absorbed by crops, which is beneficial to root and leaf surface absorption of trace elements.
Potassium humate has colloidal properties, which can loosen the soil, absorb moisture, humidify and breathe, raise moisture, prevent drought, and make the soil have good conditions of water, gas and heat, suitable for seed germination and seedling growth.
Tillering and reducing the openness rate have a good effect, increasing the grain weight by 1000 grains, thereby increasing the grain yield; if sprayed on the leaves of the crop, it can close the pores of the crop and reduce the water transpiration of the plant, and the base fertilizer can stimulate the root growth of the crop and make the crop The ability to absorb water and nutrients is greatly enhanced, which is manifested in plant height, stem diameter, and leaf thickness.
When potassium humate is decomposed by microbes, it will release heat, which will raise the ground temperature and can resist cold. Function; it has many functional groups, which can be combined with acid and combined with alkali to adjust the pH of the soil according to crop needs.
It can also participate in the particle exchange reaction in the soil, adsorbing and fixing the heavy metal ions in the soil, and reducing the metal content of the agricultural products.
