Ammonium nitrogen fertilizer
Ammonium nitrogen fertilizer is more commonly used, the main characteristics of water soluble;
Ammonium ions are positively charged and negative electricity particles hold each other.
Nitrification turns nitrification nitrogen to increase the effectiveness of nitrogen fertilizers;
Ammonium is mixed with alkali to change ammonia, and ammonia gas is not fattened.
1 Ammonium bicarbonate
Ammonium bicarbonate is alkaline and applied to soil becomes medium.
Nitrogen 16 to 17 is suitable for various crops.
High temperature and high humidity are easy to decompose, and the application must be buried deep.
Keep in mind that molybdenum is mixed with calcium, magnesium, and phosphorus, as well as urine manure from people with grass dust
2 ammonium sulfate
Ammonium thiosulfate is commonly referred to as fertilizer field fertilizer, and nitrogen fertilizer is used as a standard.
With nitrogen up to 21, all kinds of crops are suitable.
The physiological acidity is more typical and the most suitable soil is alkaline.
The mixed Pu-Ca changed to mono-ammonium, and the complementary effects of N and P increased.
3 ammonium chloride
Ammonium chloride, physiological acid, content 25 nitrogen;
Use 10 million molybdenum for seedling emergence.
Keep in mind sweet potato, tobacco, sugar beet, avoid chlorine.
Reuse of cotton and rice, the effect of blending urea fertilizer is high.
Nitrate nitrogen fertilizer
Nitrate-nitrogen fertilizers come out early and are used as top-dressing fertilizers.
The main nutrients are nitrogen, and sodium and calcium ions are also effective.
Nitrate ion with negative electricity, soil rubber adsorption difficult.
However, the water-soluble fertilizer is easy to be effective, and has strong moisture absorption and deflagration.
1 Sodium nitrate
Nitrate, sodium nitrate, is used in dry lands.
The optimum crop is beet, radish and flax.
With a lower nitrogen content of fifteen, it is also suitable for other crops.
Physiological reactions are alkaline, do not use salt and water.
2 calcium nitrate
Nitrate calcium nitrate in Norway does not decompose under normal temperature.
Nitrogen 14 physiological base, soluble in water is a weak acid.
All types of soil are suitable, it is best applied to calcium deficiency fields.
Optimum crop potato, beet barley and rice.
Ammonium and nitrate nitrogen fertilizers
Ammonium nitrate is an organic compound known as ammonium nitrate fertilizer.
Typical representatives of ammonium nitrate, nitrogen fertilizer family that backbone.
New sulfur ammonium nitrate fertilizer, with a content of up to twenty-seven.
Ammonium calcium nitrate has a promising ability to neutralize pH.
1 ammonium nitrate
Ammonium nitrate, physiological acid, containing thirty-four nitrogen.
Each half of ammonium nitrate, strong moisture absorption and deflagration.
The best application is top dressing, and no paddy soil is mixed.
Potassium fertilizer potassium chloride blended, the physical and chemical properties greatly changed.
2 Sulfur ammonium nitrate
Ammonium sulfate is a double salt, soluble in water and weak acid.
Nitrogen up to twenty-seven, ammonium nitrogen and nitrate three to one.
Because it contains ammonium nitrogen, do not mix alkaline fertilizer.
Adapt to various crops, the most suitable for top dressing.
3 calcium ammonium nitrate
Calcium ammonium nitrate is a complex salt, also known as lime ammonium nitrate.
Contains calcium carbonate to reduce caking and deflagration.
Generally nitrogen 22, easily soluble in water is a weak base.
Ammonium nitrate nitrogen and nitrogen, the effect of mixed calcium phosphate fertilizer.
Amide, cyanamide nitrogen fertilizer
Amide nitrogen fertilizers such as urea, no ions can adsorb.
The urease acts to change the ammonium bicarbonate, and then it is watered with fertilizer.
Cyanamide nitrogen fertilizer lime nitrogen, human soil into cyanide.
It is then converted to urea and it takes seven days to change to ammonium bicarbonate.
Urea
The urea is neutral and suitable for all types of soil.
Nitrogen up to forty-six, outside the top dressing heroes.
Apply to the soil to change to ammonium bicarbonate before you can flood.
Do not forget to deepen and apply ahead of schedule.
2 lime nitrogen
Lime nitrogen, toxic, insecticidal effect.
The soil is piled up with urea and the black powder is light in texture.
Twenty-nine nitrogen partial alkali, molybdenum calcium ammonium phosphate.
Contact with skin to flush, Mausch Cruciferae.
Liquid nitrogen fertilizer
Liquid nitrogen fertilizer nitrogen solution, ammonia liquid ammonia is a liquid.
Although it is currently used in small quantities, the prospects for development are extremely high.
The reason is that the equipment is relatively simple and the production cost is low.
Fertilization is easy to mechanize, cheap and labor saving.
1 ammonia water
Synthetic nitrogen is absorbed by water to produce aqueous ammonia as a base.
Strong corrosive insecticide, storage, transportation and sealing security.
Appropriate use of ammonium sulfate, more convenient with water irrigation,
Regardless of paddy fields and drylands, emphasis on deep burial is the key.
2 liquid ammonia
Liquid ammonia comes from gaseous ammonia and is cooled to liquid ammonia by pressure.
Low boiling point for the base, in the case of chlorobromine iodine deflagration.
Applied to the soil adsorption is fast, the key to deep buried.
Storage and transportation require the use of steel cylinders, which cannot be used without capping.
3 nitrogen solution
Several nitrogen fertilizers dissolve in water and produce a nitrogen solution directly.
Volatile little alkali, add phosphorus and potassium into compound fertilizer.
Storage and transportation are convenient and the development prospects are considerable.
The method of application is like ammonia, keeping in mind that deep burial is a link.
The groundbreaking four-chambered structure, differing from the conventional three-chambered structure, has more stable and safer design. The integrated panel design, in combination with the smooth and elegant line type, artistic terminal dust cover design and incomparable production process, creates an aesthetic visual experience and embodies a unique fashion.
