    Urea phosphate, also known as urea phosphate or urea phosphate, is a ruminant feed additive that is superior to urea and can provide non-protein nitrogen and phosphorus at the same time. It is an organic matter with the chemical formula CO(NH2)2·H3PO4. It is easily soluble in water, and the aqueous solution becomes acidic; it is insoluble in ethers, toluene and carbon tetrachloride.


    Superphosphate is also called general calcium phosphate, or general calcium for short. It is the first kind of phosphate fertilizer produced in the world, and it is also a kind of phosphate fertilizer widely used in our country. The effective phosphorus content of superphosphate varies greatly, generally between 12% and 21%. Pure superphosphate is dark gray or off-white powder, slightly sour, easy to absorb moisture, easy to agglomerate, and corrosive. After being dissolved in water (the insoluble part is gypsum, accounting for about 40% to 50%), it becomes acidic quick-acting phosphate fertilizer.
    Superphosphate is suitable for various crops and various soils. It can be applied to neutral, calcareous phosphorus-deficient soil to prevent fixation. It can be used as base fertilizer, top dressing, seed fertilizer and root top dressing.
    When superphosphate is used as the base fertilizer, the application rate per mu can be about 50kg per mu for the soil lacking available phosphorus, and half of it is evenly sprinkled before the cultivated land, combined with the cultivated land as the base fertilizer. Before planting, sprinkle the other half evenly, combine with the ground preparation and apply shallowly into the soil to achieve layered application of phosphorus. In this way, the fertilizer effect of superphosphate is better, and the utilization rate of its effective ingredients is also high. If mixed with organic fertilizer as base fertilizer, the application rate of superphosphate per mu should be about 20-25kg. Concentrated application methods such as ditch application and acupoint application can also be used.


    The chemical formula is KCl, which is a colorless slender rhombus or a cubic crystal, or a small white crystalline powder, with an appearance like table salt, odorless and salty. Commonly used as additives for low sodium salt and mineral water. Potassium chloride is a commonly used electrolyte balance regulator in clinical practice. It has a definite clinical effect and is widely used in various clinical departments.


    MKP is a chemical with the chemical formula KH2PO4. Deliquescence. It melts into a transparent liquid when heated to 400°C, and solidifies into an opaque glassy potassium metaphosphate after cooling. Stable in the air, soluble in water, insoluble in ethanol. Industrially used as a buffer and culture agent; also used as a bacterial culture agent to synthesize a flavoring agent for sake, a raw material for making potassium metaphosphate, a culture agent, a strengthening agent, a leavening agent, and a fermentation aid for brewing yeast. In agriculture, it is used as a high-efficiency phosphate-potassium compound fertilizer.


    Manganese sulfate is a trace element required by crops that synthesize fatty acids. Therefore, manganese sulfate can be used as a fertilizer and applied to the soil to increase production. Adding manganese sulfate to animal feed has a fattening effect. Manganese sulfate is also a raw material and analytical reagent for the preparation of other manganese salts. Manganese sulfate is also used in industrial production such as electrolytic manganese, dyes, papermaking, and ceramics. [1] Due to deliquescent, the scope of application is limited. Manganese sulfate is non-flammable and irritating. Inhalation, ingestion or transdermal absorption is harmful and has a stimulating effect. Long-term inhalation of the product dust can cause chronic manganese poisoning. The early stage is mainly neurasthenia syndrome and neurological dysfunction, and the late stage tremor paralysis syndrome. It is harmful to the environment and can cause pollution to water bodies. In addition, manganese sulfate has various hydrates such as manganese sulfate monohydrate and manganese sulfate tetrahydrate.

Easily soluble in hot water, soluble in cold water, methanol, ethanol, and liquid ammonia. Its aqueous solution is neutral. It can be used as a dehydrating agent, a catalyst for concentrated nitric acid and a wheat ashing agent and catalyst.
  • NPK fertilizer

    NPK fertilizer

    The advantage of compound fertilizer is that it has comprehensive nutrients, high content, and contains two or more nutrient elements, which can supply the multiple nutrients needed by crops in a relatively balanced manner and for a long time. Improve the effect of fertilization. Good physical properties, easy to apply: The particle size of compound fertilizer is generally more uniform and less hygroscopic, which is convenient for storage and application, and is more suitable for mechanized fertilization. There are few auxiliary components and no adverse effects on the soil.
  • Ammonium Sulphate Capro Grade

  • Caustic Soda

    Caustic Soda

    Caustic soda is a white solid with strong hygroscopicity. It will melt and flow after absorbing moisture. It can absorb water and carbon dioxide in the air to produce sodium carbonate. It is brittle, soluble in water, alcohol, glycerin, but insoluble in acetone. A lot of heat is released when melting. The aqueous solution is slippery and alkaline. It is highly corrosive and can burn the skin and destroy the fibrous tissue. Contact with aluminum at high temperatures produces hydrogen. It can neutralize with acids and generate a variety of salts. Liquid sodium hydroxide (ie, soluble alkali) is a purple-blue liquid with a soapy and slippery feel, and its properties are similar to solid alkali.
    The preparation of caustic soda is electrolytic or chemical. Chemical methods include lime causticization or ferrite.

  • Potassium Humate

    Potassium Humate

    Potassium humate is a strong alkali and weak acid salt formed by ion exchange between weathered coal and potassium hydroxide. According to the ionization theory of substances in aqueous solutions, after potassium humate is dissolved in water, potassium will ionize and exist alone in the form of potassium ions. Humic acid molecules will combine with hydrogen ions in the water and release hydroxide ions at the same time, thus potassium humate solution Significantly alkaline. Potassium humate can be used as an organic fertilization. If the brown coal humate has a certain anti-flocculation ability, it can be used as a drip fertilizer in some areas where the water hardness is not high, or it can be combined with other non-acidic nitrogen and phosphorus nutrients. Elements, such as monoammonium phosphate, are used in conjunction to improve the overall use effect. Promote the development of crop root system and increase the germination rate. Potassium fulvic acid is rich in a variety of nutrients. New roots can be seen after 3-7 days of use. At the same time, a large number of secondary roots can be increased, which can quickly improve the ability of plants to absorb nutrients and water, promote cell division, and accelerate crop growth.
