What is the difference between monoamine fertilizer and diamine fertilizer?

There are two differences between monoammonium and diammonium:

1. Ratio of nitrogen and phosphorus: monoammonium phosphate.

The ratio of nitrogen to phosphorus is 1: (4-5), while diammonium phosphate.

The ratio of nitrogen to phosphorus is close to 1:2, and diammonium phosphate is more easily absorbed and utilized according to the optimal absorption ratio of the elements by crops.

2. The pH value of both.

Monoammonium phosphate is acidic when dissolved into water, while diammonium phosphate is alkaline, so different soil conditions, the application of two fertilizers will have different results.

2. Suggestions for use.

Diammonium phosphate in the bottom fertilizer in the water hardness is larger, the soil calcium content is higher, the pH value of the water and soil is neutral or alkaline, the actual utilization efficiency is very low, only the application of acid fertilizer can play a role, it is recommended that the water hardness is larger, the soil calcium content is higher in the area, try to use compound fertilizer.

Acidic fertilizers such as monoammonium phosphate and superphosphate are used as base fertilizers to replace diammonium phosphate, and at the same time, a small amount of water-soluble phosphate fertilizer is supplemented by drip irrigation or sprinkler irrigation during the growth period to ensure the normal nature of phosphate fertilizer. In the acidic soil in the south, diammonium phosphate can be applied to neutralize the soil acidity and improve the use efficiency of phosphate fertilizer.

The difference is that one ammonium contains 1 NH4 ion, diamine contains 2 NH4 ions, and the monoamine fertilizer is ammonium dihydrogen phosphate.

Chemical agents, also known as monoammonium phosphate.

It is mainly used as fertilizer and fireproof agent for wood, paper, fabric, and is also used in pharmaceuticals and ruminants.

Feed additives.

Diamine fertilizer is a white crystal or powder of hydrogen diamine, which is used as fertilizer and fireproof agent for wood, paper and fabric, and is also used in medicine, sugar, feed additives, yeast and other aspects. Therefore, both can be used as fertilizers.

Whether it is a amine or diamine, it belongs to the category of phosphate fertilizer, the role of phosphate fertilizer is used to raise seedlings, that is, when the plant first begins to develop, it is used in the late maturity period, and the phosphate fertilizer is almost not used, and the amine is acidic, the diamine is alkaline, and the amine can regulate the compacted soil, but the release rate of the amine is faster than the diamine, and the fertilizer effect is great without adding a slow-release agent, and the failure is also fast.

When the radish is large, it is not necessary to use nitrogen fertilizer, so more potassium fertilizer should be applied. It doesn't matter if it's monoamine or diamine.

Fertilizer diamine generally refers to diammonium phosphate, which has many effects.

1. The effect on wheat is to strengthen seedlings, improve its ability to resist drought and lodging, increase the number of ears, and promote grain fullness.

2. The effect on rice is to promote tillering, prevent root rot, increase the number of ears and grains, etc.;

3. The effect on corn is to improve its ability to resist drought and lodging, increase the number of corn cobs, and promote the fullness of grains.

4. For cotton, it has the effect of increasing the number of boll per plant, reducing bud boll shedding, and improving the quality of cotton fiber.

Specific methods of loofah fertilization.

1.Bottom fertilizer application before loofah planting. No matter what crop is planted, we apply foot fertilizer before planting, which ensures that the seedlings and germination have sufficient nutrients.

The base fertilizer is mainly organic fertilizer or farmhouse fertilizer, which can be matched with an appropriate amount of chemical fertilizer or inorganic fertilizer, using 3,000 to 5,000 catties of rotted farmhouse fertilizer per mu, 30 to 50 kilograms of compound fertilizer, evenly sprinkled in the soil, and then buried in the soil when ploughing.

2.Fertilizer application at loofah seedling stage. At the seedling stage of loofah, the flower buds begin to differentiate, and the plant needs to absorb a large amount of nitrogen fertilizer to synthesize the protein needed for flower bud differentiation and vegetative growth, and also needs a small amount of phosphorus and potassium fertilizer to coordinate plant growth.

When fertilizing, combined with the specific soil conditions, apply an appropriate amount of organic fertilizer, use 100 to 150 kg of well-rotted organic fertilizer with water each time, and fertilize two to three times at the seedling stage.

Finally, it is the fertilization of the loofah during the growing period. Reasonable fertilization can ensure the high yield and taste of loofah, at this time a large amount of nitrogen and potassium are needed, but nitrogen fertilizer should not be excessive, otherwise the plant will grow, flowering and melon will be affected, top dressing must be done a small amount of many times. During the growing season, fertilization needs to be applied three to four times, each time fertilizing 200 to 300 kilograms of rotting human manure per mu, or 20 to 30 kilograms of phosphorus and potassium compound fertilizer.

Only by doing it reasonably and with the right amount of fertilization can we increase the yield of loofah and ensure the taste and market demand.

Diamine is a diammonium phosphate fertilizer.

Diamine refers to diammonium phosphate fertilizer, also known as diammonium phosphate. This is a high-concentration of fast-acting nitrogen and phosphorus compound fertilizer, containing 18% nitrogen and 46 phosphorus, suitable for all kinds of crops and soils, especially suitable for crops that like nitrogen and phosphorus, as base fertilizer or top dressing, should be applied deeply. Diammonium fertilizer can be applied in combination with ammonium bicarbonate, urea, ammonium chloride, potassium chloride, ammonium nitrate and other fertilizers, and avoid mixing with acidic fertilizers such as ammonium sulfate and superphosphate.

Diamine

1. Diamine refers to diammonium phosphate fertilizer (also known as diammonium hydrogen phosphate). As a high-concentration of available nitrogen and phosphorus compound fertilizer, diammonium phosphate is suitable for various crops and soils, especially for sugarcane, water chestnuts and other nitrogen-loving and phosphorus-needing crops, as base fertilizer or top dressing, should be applied deeply.

2. Diamine phosphate is a colorless transparent monoclinic crystal or white powder, in order to increase storage resistance, some products are added with a wrapping agent in the production process to make the appearance of the product brown. Soluble in water, insoluble in alcohol, acetone, ammonia. Generally, it can be applied in combination with ammonium bicarbonate, urea, ammonium chloride, potassium chloride, ammonium nitrate and other chemical fertilizers, and avoid mixing with acidic fertilizers such as ammonium sulfate and superphosphate.

The phosphorus element in diammonium can not only promote the accelerated growth of crop roots and aboveground parts, but also ensure the needs of grain and fruit development in the later stage of crop growth, as well as the adaptability of crops to the external environment, promote early fruit maturity, improve crop quality, and participate in photosynthesis and respiration in crops. In phosphorus-deficient land, the application of diamine can achieve a significant yield increase in the first year, regardless of the crop.

Diamine fertilizer is the so-called diammonium phosphate, which is a compound fertilizer containing nitrogen and phosphorus. Its uses are:
