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.
