1. Product Introduction
The potassium humate extruded granules produced by our company are made from the waste materials left over from the production of potassium humate. After drying, they are fed into an extrusion granulator to retain the activity of humic acid organic matter and realize the resource utilization of waste materials. The potassium humate extruded granules have a higher hardness structure. Compared with powder, extruded granules are more convenient to fertilize, with less dust and low price. Therefore, extruded granules can be used as soil conditioners.
The main characteristics of potassium humate extruded granules:
(1) Improve soil structure: Promote the formation of soil aggregate structure, enhance air permeability and water and fertilizer retention capacity, especially suitable for the improvement of sandy soil, heavy clay soil and other problem soils.
(2) Nutritional supplement: Contains a small amount of fulvic acid and potassium oxide, which can assist crop growth, enhance root absorption capacity, and improve crop resistance (drought resistance, cold resistance, etc.).
(3) Improve fertilizer utilization rate: It can absorb nutrients in the soil and reduce loss. When used in combination with chemical fertilizers, it can improve fertilizer efficiency and reduce fertilization costs. (4) Environmental protection and resource utilization: Realize the recycling of tailings, reduce waste pollution, and be suitable for green agriculture and ecological planting scenarios.

3. Usage method
(1) Base application: Before sowing or planting, mix with organic fertilizer or chemical fertilizer and spread evenly on the soil surface, plowing into the soil; or combine with furrow application or hole application near the root area of the crop.
(2) Topdressing: During the crop growth period, dig a furrow near the root system and apply after covering with soil, or combine with irrigation and spread a small amount (avoid direct contact with the root system).
(3) Mixed fertilizer use: It can be mixed with granular compound fertilizer, microbial fertilizer, etc. to promote crop absorption of nutrients and improve fertilizer utilization rate.
4. Target crop dosage
(1) Field crops (corn, wheat, etc.): Base application of 3000-6000 kg per hectare; topdressing of 1500-3000 kg per hectare during the growth period.
(2) Fruit trees and vegetables: Base application of 1500-3000 kg per hectare during the sapling/seedling stage; base application of 4500-7500 kg per hectare during the mature stage, and topdressing of 3000-4500 kg per hectare during the growth period.
(3) Soil improvement: For poor or saline-alkali soils, the initial application can be appropriately increased to 7500-15000 kg per hectare, and subsequently adjusted according to soil improvement conditions.
