The use of sulfur in chemical fertilizers, what is the role of sulfur in chemical fertilizers

Sulfur is important in industry, for example as sulfuric acid in batteries or in solution. Sulfur was used to make black powder. It is used as a vulcanizing agent in the rubber industry. Sulfur is also used to kill fungi.

It is used as a fertilizer. Sulfides are used for bleaching in the paper industry. Sulfates also have uses in pyrotechnics. Sodium thiosulfate.

and ammonium thiosulfate as a fixer in photography. Magnesium sulfate.

It can be used as a lubricant, added to soaps and gentle scrubs, and can also be used as a fertilizer.

The role of the element sulfur:

1. Sulfur is an important component of cystine, cysteine and methionine, and about 90% of sulfur exists in sulfur-containing amino acids in plants;

2. Sulfur is involved in the formation of chlorophyll;

3. Sulfur plays an important role in the formation and activation of certain enzymes in plants;

4. Sulfur is involved in the synthesis of vitamins H and B;

5. Glycoside oil of cruciferous plants;

6. Sulfur is related to the protein structure that affects the cold and drought resistance of plants, and sulfur can increase the cold and drought resistance of some crops;

7. Sulfur is related to nitrogen fixation by rhizobia and autogenous nitrogen-fixing bacteria. The lack of sulfur in crops affects their normal growth, resulting in a decrease in yield and quality.

The main role of sulfur fertilizer is to improve alkaline soil. The application of sulfur fertilizer is an important means of supplementing soil sulfur, and usually sulfur is applied together as a by-component or addition of ordinary fertilizer.

For some low-yield soils lacking in sulfur, the application of gypsum and other sulfur fertilizers has the effect of improving the nutrition of crops, and the seedlings that "sit dead" and "turn yellow" can return to green after 3 5 days of gypsum.

It has also been observed that the rational use of sulfur fertilizer can improve the volatility of onions, garlic and mustard greens.

The content of chemical compounds can help to improve the nutritional levels of some vegetables and fruits.

Some crops require more sulfur to grow and develop properly.

Increase the absorption and utilization of sulfur by plants.

The addition of sodium thiosulfate to a large number of elemental liquid fertilizers can further increase the absorption and utilization of sulfur by plants, promote the growth and development of plants, and also increase the content of ammonia nitrogen and nitrate nitrogen in foliar and soil to improve fertilizer efficiency.

Macroelemental liquid fertilizers are commonly used for nutrient replenishment during plant growth. Sodium thiosulfate, also known as sodium imomethane sulfate, is an inorganic salt similar in structure to ammonium sulfate. Thiosulfate shalt is widely used in agricultural slag production.

1.Pure sulfur is a concept launched by Stanley Company in order to achieve product differentiation and has registered a trademark with the Industrial and Commercial Bureau.

The pure sulfur-based compound fertilizer on the market now refers to the compound fertilizer produced with potassium sulfate as raw material, and the mountain is like acacia rather than the potassium sulfate compound fertilizer with potassium chloride dechlorination as raw material. Amusement.

2.In essence, according to the national standard, as long as the chloride ion content is less than 3%, it is potassium sulfate compound fertilizer, and potassium sulfate is also produced from potassium chloride as raw material.

So there is no essential difference between the two.

Pure sulfur-based compound fertilizer means that all anions are sulfate, because sulfate and phosphate cannot be combined, so there is no phosphorus, and no chlorine and no nitrate. The limitations of this fertilizer are too small, and such a rigid rule has lost its meaning.

1. Sulfur is an important component of cystine, cysteine and methionine, and about 90% of sulfur exists in sulfur-containing amino acids in plants;

2. Sulfur is involved in the formation of chlorophyll;

3. Sulfur plays an important role in the formation and activation of certain enzymes in plants;

4. Sulfur is involved in the synthesis of vitamins H and B;

5. Glycoside oil of cruciferous plants;

There are 16 types of nutrients needed for crop growth. According to the growth requirements of crops, they are divided into two categories: macronutrients and micronutrients.

Macronutrients are divided into three categories: one is carbon, hydrogen, and oxygen, which crops can obtain directly from air and water, which are not within the scope of fertilizers; The second category of nitrogen, phosphorus and potassium, known as the main macronutrients, is the main content of chemical fertilizers; The third category of calcium, magnesium and sulfur is called secondary macronutrients (known as medium nutrients in China).

Sulfur has a unique effect on increasing crop yield and improving crop quality, and the application of sulfur fertilizer can promote protein synthesis, increase the oil content of oil crops, enhance the nitrogen fixation capacity of soybean crops, and increase the spicy smell of onions, garlic and vegetables.

Sulfur is known as the fourth most important element for plant growth, and crops usually need as much sulfur as phosphate.

The roles of sulfur in plant physiology and crop production are:

1. Sulfur is an important component of cystine, cysteine and methionine, and about 90% of sulfur exists in sulfur-containing amino acids in plants;

2. Sulfur is involved in the formation of chlorophyll;

3. Sulfur plays an important role in the formation and activation of certain enzymes in plants;

7. Sulfur is related to nitrogen fixation by rhizobia and autogenous nitrogen-fixing bacteria. The lack of sulfur in crops affects their normal growth, resulting in a decrease in yield and quality.

There are many types of sulfur** in soils, including soil sulfur, sulfur in rainfall and irrigation water, sulfur in atmospheric deposition, and sulfur in sulfur fertilizers and pesticides. The best indicators of soil sulfur supply capacity are soil organic matter content and soil texture, and most sulfur-deficient soils are sandy soils with low organic matter content. Sulfur fertilizer is one of the main nutrients of crops.

Due to the development of the fertilizer industry, the commonly used sulfur-containing fertilizers in the past, such as: superphosphate, ammonium sulfate and potassium sulfate, etc., are replaced by fertilizers with high active ingredients that do not contain sulfur or have less sulfur, such as urea, ammonium phosphate, compound fertilizer, etc., and the sulfur taken away by crops from the soil can not be supplemented with sulfur in time, which will cause soil sulfur deficiency. In recent years, the potassium sulfate compound fertilizer that has emerged has generally worked well after being used by farmers.

Extended information: Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods containing nutrients necessary for the growth of one or several crops. Also known as inorganic fertilizer, including nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, micro fertilizer, compound fertilizer, etc.

Phosphate fertilizer, nitrogen fertilizer, and potassium fertilizer are chemical fertilizers that are in high demand for plants.

The macronutrients nitrogen, phosphorus and potassium in the soil usually cannot meet the needs of crop growth, and chemical fertilizers containing nitrogen, phosphorus and potassium need to be applied to make up for it. In addition to chlorine, which is not lacking in the soil, several other nutrients need to be fertilized with micronutrients. Chemical fertilizers are generally inorganic compounds, and only urea [CO(NH2)2] is an organic compound.

Fertilizers that contain only one type of nutrient element that can be labeled are called unit fertilizers, such as nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, etc. Any chemical fertilizer that contains two or more of the three nutrients of nitrogen, phosphorus and potassium and whose content can be indicated is called compound fertilizer or mixed fertilizer. Grade is the main indicator of fertilizer quality.

It refers to the percentage of available nutrients or their oxides in a fertilizer product.

Sulfur is a very beneficial element for the growth of crops, and has a variety of roles in plant metabolism, especially in the formation of amino acid proteins, and has a great impact on the synthesis of crop proteins, oils, vitamins and glucose. In addition, sulfur is found in other organisms such as grape liver, and is necessary for the synthesis of certain cellulose and the formation of chlorophyll. Nitrogen uptake by plants should be premised on the presence of sulfur, which in some cases plays an important role in the uptake of phosphate by the soil.

Sulfur can not only increase protein content, improve the quality of feed and cereal crops, increase vitamin A content and oil content of oil crops, but also improve the quality of fruits, vegetables, sugar beets and other varieties, and can enhance the cold and drought resistance of crops.
