Water soluble fertilizer raw material
China's agriculture is gradually developing towards intensification and scale. With the gradual lack of water resources and the increasing number of large-scale farms, drip irrigation and sprinkler irrigation water-saving facilities are also developing at a relatively fast pace. There are more and more areas to understand. The importance of the water-soluble fertilizer raw material industry, because it is more in line with the requirements of environmental protection and sustainable development, is also an important project for the development of China's fertilizer industry and industry.
There are two broad categories of water-soluble fertilizer raw materials: one is inorganic and the other is organic. Generally, only the following various raw materials are used:
Nitrogen fertilizer: phosphorus nitrate, diammonium hydrogen phosphate, urea, ammonium sulfate, ammonium chloride, ammonium nitrate, ammonium hydrogencarbonate, nitrogen fertilizer has strong moisture absorption, can be dissolved in water, but sulfate and calcium and magnesium in water The ionic reaction produces an insoluble sulfate.
Phosphate fertilizer: "industrial grade monophosphate, industrial grade diammonium phosphate, potassium dihydrogen phosphate, ammonium polyphosphate.
Potassium fertilizer: potassium nitrate, potassium chloride, potassium sulfate, phosphoric acid = potassium hydrogen.
Calcium fertilizer: calcium ammonium nitrate, calcium carbonate calcium carbonate, and the like.
The organic water-soluble fertilizer raw material is fluorine-based fulvic acid, potassium fulvic acid, sodium humate, sodium alginate, chitosan and the like.
The commonly used trace elements are boron, iron, dilute, zinc, copper, copper, etc., and the cations that trace the trace elements react with the acid radicals to form water-insoluble matter. Medium amount of elements: calcium, sulfur, silicon fertilizer, etc.
