Chloride base, sulfur base, potassium sulfate type, double sulfur base compound fertilizer, do you know how?
1. Nitrate-sulfur compound fertilizer refers to a compound fertilizer made of nitrogen provided by ammonium nitrate and potassium derived from potassium sulfate or removing chloride ions from potassium chloride.Biuret free, less than 3% chloride.2. Sulfur compound fertilizer refers to the compound fertilizer that uses potassium sulfate as the source of potassium, and contains low chloride ion, less than 3% according to the national standard.It is suitable for all kinds of soil and crops, and can effectively improve the appearance and quality of all kinds of cash crops, and can significantly improve the grade of agricultural products.Sulfur compound fertilizer is the fourth nutrient element after nitrogen, phosphorus and potassium, which can effectively improve the sulfur deficiency in soil and directly provide sulfur for crops.Sulfur compound fertilizer can be used as base fertilizer, topdressing, seed fertilizer and topdressing outside the root;Chlorine-based compound fertilizer can not be used for seed fertilizer and topdressing outside the root, so as not to produce fertilizer harm.3. Chlorine-based compound fertilizer refers to the existence of potassium in the form of potassium chloride, which can be divided into monochlorinated and dichlorinated products. Monochlorinated means that except potassium in the form of potassium chloride, nitrogen is made from urea without chloride ions.The national standard of compound fertilizer stipulates that compound fertilizer containing chlorine must be marked with chlorine ion content, such as low chlorine (3-15% chloride ion), medium chlorine (15-30% chloride ion), high chlorine (more than 30% chloride ion).Generally speaking, the application of chlorine-based compound fertilizer has adverse effects on the yield and quality of tobacco, potato, sweet potato, watermelon, grape, beet, cabbage, pepper, eggplant, soybean, lettuce and other chlorine-averse crops, and seriously reduces the economic benefits of such cash crops.At the same time, chlorine-based compound fertilizer forms a large number of residual chloride ions in the soil, which is easy to cause soil compaction, salinization, alkalization and other adverse phenomena, thus worsening the soil environment and reducing the nutrient absorption capacity of crops.It should be emphasized that proper application of field crops such as wheat, corn and gastrodia elata is not only harmless, but also beneficial to increase yields.4. Urina-based compound fertilizer refers to compound fertilizer in which nitrogen is obtained in the form of urea. Urina-based compound fertilizer is generally high in nitrogen products, especially compound fertilizer with nitrogen content of more than 20, and ammonia chloride and ammonium bicarboreal can not produce such high nitrogen content.5. Double sulfur compound fertilizer refers to the source of nitrogen is ammonium sulfate, potassium source is potassium sulfate.Common potassium sulfate and sulfur-based compound fertilizers in the nitrogen use urea conversion.We all know that the safest form of nitrogen fertilizer is ammonium nitrogen, urea is ammonium nitrate, its byproduct contains biuret, in the process of application and direct contact with the root system easy to burn roots and seedlings.At the same time, the nitrogen element in urina-based compound fertilizer needs to be transformed into ammonia nitrogen and nitrate nitrogen after being applied to soil, so that plants can absorb it, and it should be applied in advance in areas with low temperature.It can be seen that for most fruits and vegetables and other cash crops, the use of double sulfur compound fertilizer has the advantages of wide applicability, easy to use, uniform nutrients, small side effects, and is suitable for all kinds of food crops and cash crops, and plays a very important role in improving the quality and yield of crops.Composition of different nitrate sulfur compound fertilizer: nitrate nitrogen, crops can be directly absorbed.Sulfur compound fertilizer: low content of chloride ions, less than 3% according to national standards, and contains a lot of sulfur elements, can effectively improve the symptoms of soil sulfur deficiency.Chlorine-based compound fertilizer: it contains a large amount of chlorine and has adverse effects on chlorine-sensitive crops.: urea-based compound fertilizers for urea nitrogen (amide nitrogen in urea in soil, soil microbes secrete urea enzyme action, hydrolyzed into ammonium carbonate or ammonium bicarbonate when water right, the higher the temperature, the faster the hydrolysis to convey to the faster the ammonium carbonate, effectiveness is the faster, the ammonium carbonate is not very stable, so the application of urea-based compound fertilizer, should cover the soil deep, prevent n losses.Nitrate sulfur compound fertilizer with different processes:Contains nitrate and sulfate mixed NPK, raw material is made of high quality phosphate nitrate and potassium sulphate, high nitrogen high potassium, formula is reasonable, good soluble, fertilizer effect is rapid, favor the absorption of phosphorus, potassium and other nutrients, high utilization rate of fertilizer, avoid or reduce plant by nitrite accumulation, belong to high quality, green environmental protection, pollution-free new compound fertilizer.Sulfur compound fertilizer: chloride ion content is very low, the chloride ion is removed in the production process.Chlorine-based compound fertilizer: in the production process did not remove the chlorine ion harmful to avoid chlorine crops, so the product contains a large number of chlorine elements.Urine-based compound fertilizer: in the production process, molten urine from urea system or molten urine from solid urea heating system and potassium chloride or potassium sulfate are prepared into slurry.Application scope different nitrate and sulfur base compound fertilizer: suitable for dry crops, especially suitable for sulfur-loving chlorine-resistant crops or sulfur-deficient, saline-alkali soil, there is no residual pollution, as base fertilizer or topdressing, can meet the needs of nutrients in different growth periods of crops.Sulfur compound fertilizer: suitable for all kinds of soil and various crops, and can effectively improve the appearance and quality of all kinds of cash crops, can significantly improve the grade of agricultural products.Chlorine-based compound fertilizer: it has adverse effects on the yield and quality of chlorine-sensitive crops, and seriously reduces the economic benefits of such cash crops.Urine-based compound fertilizer: it is easy to produce biuret in the production process, so it should be isolated from seed fertilizer when making seed fertilizer.Different fertilizer effect nitrate sulfur compound fertilizer: compared with other traditional compound fertilizer, high nitrogen and high potassium, reasonable formula, good solubility, rapid fertilizer effect, beneficial phosphorus, potassium and other nutrients absorption, high fertilizer utilization rate.Sulfur compound fertilizer: sulfur is the fourth nutritional element after nitrogen, phosphorus and potassium, which can effectively improve the sulfur deficiency in soil and directly provide sulfur for crops.Chlorine-based compound fertilizer: a large number of residual chloride ions are formed in the soil, which is easy to cause soil compaction, salinization, alkalization and other adverse phenomena, thus worsening the soil environment and reducing the nutrient absorption capacity of crops. However, chloride ions can promote photosynthesis and fiber formation, which is especially suitable for hemp and other fiber crops.Urine-based compound fertilizer: the nitrogen element in the fertilizer needs to be converted into ammonia nitrogen and nitrate nitrogen to be absorbed by plants after it is applied to the soil. Therefore, in the application process, the area with low temperature should be applied in advance.Application methods: nitrate and sulfur compound fertilizer can be used as base fertilizer or topdressing, to meet the needs of nutrients in different growth periods of crops.Sulfur – based compound fertilizer: material – based fertilizer, top – dressing, seed fertilizer and top – dressing.Chlorine-based compound fertilizer: can be used as base fertilizer and topdressing, with base fertilizer and seed fertilizer in neutral soil and matching soil should be mixed with organic fertilizer, phosphate rock powder and so on.Urinal-based compound fertilizer: because it contains biuret, in the process of application, attention should be paid to burning seedlings, while applying deep soil to prevent the loss of ammonia.The specific scope of application of urine-based compound fertilizer depends on whether the fertilizer contains chloride ions or sulfur elements. If it contains chloride ions, the scope of application is based on chlorine-based compound fertilizer. The scope of application of urine-based compound fertilizer containing sulfur elements is based on the scope of application of sulfur compound fertilizer.(Source: Encyclopedia of Agriculture, Rural Areas and Farmers)
