Urea is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects. Animal husbandry can be used as feed for ruminants. Urea is an organic nitrogen fertilizer. After being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil, it can be absorbed and utilized by crops. Therefore, urea should be applied 4 to 8 days before the fertilization period of the crop.Urea is suitable for base fertilizer and top dressing, and sometimes as seed fertilizer. Before conversion, urea is in a molecular state and cannot be adsorbed by the soil. It should be prevented from being lost with water; the ammonia formed after conversion is also volatile, so urea should be covered with soil deeply. Urea is suitable for all crops and all soils, can be used as base fertilizer and top dressing, and can be applied in dry paddy fields. Because urea can accumulate a large amount of ammonium ions in the soil, it will increase the pH by 2-3 units. In addition, urea itself contains a certain amount of biuret. When its concentration is 500ppm, it will affect the roots of the crops. Young shoots have an inhibitory effect, so urea is not suitable for seed fertilizer.Urea (nitrogen fertilizer) can promote cell division and growth, making branches and leaves grow luxuriantly.
Properties: colorless transparent prismatic or white particles or crystalline powder, 100% soluble water. High-quality nitrogen and potassium binary compound fertilizer, 100% plant nutrients. Features: (1) The ratio of sodium to potassium is 1:3, which is in line with the absorption ratio of general crops For example, the client wants to promote absorption by crops and promote other elements (calcium, magnesium) The absorption ratio. Can be quickly absorbed by crops during the peak period of crop fertilizer demand use. (2) No chlorine, no sodium, no residual harmful substances (3) It can solve the soil acid caused by the long-term use of other chemical fertilizers in the soil. Problems of integration and compaction.
Properties: colorless and transparent crystals, easily soluble in water, methanol, ethanol, and highly deliquescent in the air. It is an oxidant. It will burn and explode when encountering organic matter and sulfur, and emit a red flame.Uses: It is a raw material for the manufacture of nitrates. Agriculture is a fertilizer containing nitrogen and quick-acting calcium. Its fertilizer effect is fast, and it has the characteristics of rapid nitrogen and calcium supplement. In industry, calcium nitrate is mainly used as a refrigerant, a flocculant in the rubber industry, and also in the manufacture of fireworks and explosives. Scope of application: It is suitable for a variety of soils and crops, and is widely used for food crops, cash crops, flowers, fruit trees, vegetables, etc. grown in greenhouses and fields. The nitrate nitrogen in calcium ammonium nitrate does not need to be transformed in the soil first, but is quickly dissolved in water and absorbed directly by plants. Suitable for base fertilizer, seed fertilizer and top dressing.
Properties: white round granulation, 100% soluble in waterUses: It is a new high-efficiency compound fertilizer containing nitrogen and quick-acting calcium. Its fertilizer effect is fast, and it has the characteristics of rapid nitrogen replenishment. Among them, calcium and magnesium are added, and the nutrients are more comprehensive than ammonium nitrate, which can be directly absorbed by plants; this product is a neutral fertilizer with low physiological acidity and has an improvement effect on acid soil. After being applied to the soil, the pH is low, which will not cause soil compaction and can make the soil loose. At the same time, it can reduce the concentration of active aluminum, reduce the fixation of active phosphorus, and provide water-soluble calcium, which can improve the resistance of plants to diseases. Can promote the activity of beneficial microorganisms in the soil. When planting cash crops, flowers, fruits, vegetables and other crops, the fertilizer can prolong the flowering period, promote the normal growth of roots, stems, and leaves, ensure the bright color of the fruit, and increase the sugar content of the fruit.Scope of application: It is suitable for a variety of soils and crops, and is widely used for food crops, cash crops, flowers, fruit trees, vegetables, etc. grown in greenhouses and fields. The nitrate nitrogen in calcium ammonium nitrate does not need to be transformed in the soil first, but is quickly dissolved in water and absorbed directly by plants. Suitable for base fertilizer, seed fertilizer and top dressing.
Properties: colorless monoclinic crystal or white crystal, easily soluble in water, liquid ammonia, methanol and ethanol. It is stable at room temperature, with a relative density of 1.461, which is higher than the melting point of 95°C and dehydrated to form basic magnesium nitrate. It will start to decompose when heated to 300°C, and completely decompose into magnesium oxide and nitrogen oxide gas when it reaches 400°C.Uses: Industrially used as a dehydrating agent for concentrated nitric acid, manufacturing explosives, catalyst catalysts and other magnesium and nitrate raw materials, wheat ashing agent, etc. In agriculture, soluble nitrogen and magnesium fertilizers are used as fertilizers for soilless cultivation.

Uses: Mainly used in agriculture as a nitrogen fertilizer. The advantage is that it has relatively low hygroscopicity and is not easy to agglomerate. Compared with ammonium nitrate and nitrogen ammonium, it has excellent physical properties and chemical stability. Ammonium sulfate is a quick-acting fertilizer, which is alkaline in the soil, suitable for alkaline soil and carbonaceous soil. The disadvantage is that the nitrogen content is low, but ammonium sulfate contains sulfur in addition to nitrogen, which is beneficial to crops. Exceptions are also widely used in industry, such as the fermentation nitrogen source for enzymes in medicine, dyeing and printing auxiliary in textiles, and refined ammonium sulfate for brewing.Storage and transportation: Store in a ventilated and dry warehouse. The packaging is sealed to avoid dampness, and to prevent the rain from melting and losing during transportation.
