Classification characteristics and application of urea ammonium phosphate, aaty mmonium, phosphorus and potassium compound fertilizer. We also provide professional NPK fertilizer production machine and production line.

Urea ammonium phosphate

Ammonium phosphate of urea is composed of CO (NH2) 2 · (NH4) 2HPO4, which is made of ammonium phosphate and urea. Its nutrient content can be 37-17-0, 29-29-0, 25-25-0 and so on. It is a high concentration of nitrogen and phosphorus compound fertilizer. N and P nutrients are water soluble, and N: P2O5 is 1:1 or 2:1, which is easy to be absorbed by crops.

Ammonium, phosphorus and potassium fertilizers

Ammonium phosphate potassium fertilizer is a ternary compound fertilizer made of ammonium sulfate, potassium sulfate and phosphate in different proportions, or by adding potassium salt into ammonium phosphate. The nutritional ratios were 12-24-12, 10-20-15 and 10-30-10, respectively.

The proportion of phosphorus in ammonium phosphate and potassium fertilizer is relatively large, so nitrogen and potassium fertilizer can be applied properly, and the ratio can be adjusted to give full play to fertilizer efficiency. Potassium ammonium phosphate fertilizer is a kind of high concentration compound fertilizer. How to make npk compound granules? Go here for more.

Potassium dihydrogen phosphate

Potassium dihydrogen phosphate is a kind of high concentration phosphorus potassium binary compound fertilizer, pure white or grayish white crystal, nutrient is 0-52-34, small hygroscopicity, good physical properties, soluble in water, water solution ph3-4, expensive.

Potassium dihydrogen phosphate is suitable for seed soaking, seed dressing and topdressing. The soaking concentration was 0.2% and the soaking time was 12 hours. Soybean and wheat were soaked in 30kg and 50kg solution, respectively. Seed dressing is usually sprayed with 1% concentration and seed mixed on the same day. The spraying concentration was 0.2% – 0.5%, and 50kg-75kg solution was used every 667m2. Choose to spray the leaves on the ground on a sunny afternoon without dripping. Wheat at jointing booting stage and cotton before and after flowering were sprayed three times. Spraying 0.5% potassium dihydrogen phosphate solution during fruit expansion and coloring has a good effect on improving product quality.

Potassium nitrate is usually called pyronitrate. It is recrystallized from sodium nitrate and potassium chloride or extracted from nitroso. Its molecular formula is KNO3. It contains 13% N and 46% K2O. Pure potassium nitrate is white crystal, crude product is slightly yellow, hygroscopic, soluble in water, chemical neutral, physiological neutral fertilizer. It is easy to explode at high temperature and belongs to flammable and explosive substances.

It is suitable for dry land, generally 5-10 kg / 667 m2. It has a good effect on potato, tobacco, beet, grape, sweet potato and other crops that prefer potassium rather than chlorine frost. It has a good response in legume crops. If it is used for other crops, it should be combined with element nitrogen fertilizer to improve fertilizer efficiency. Potassium nitrate can also be used as root topdressing, and the suitable concentration is 0.6% – 1%. In arid areas, it can also be applied with organic fertilizer, the dosage is about 10kg / 667m2.
As the N: K2O ratio of potassium nitrate is 1:3.5, the content of potassium is higher, so the calculation of fertilizer should be based on the content of potassium.

The effect of organic fertilizer was slow, and the effect of topdressing was not as obvious as that of base fertilizer before sowing or transplanting.

When is organic fertilizer usually applied? For greenhouse growers, organic fertilizer should be applied before soil sterilization.

NPK compound fertilizer contains two or more kinds of macroelements, which can provide rich nutrition for the growth and development of soil and plants. What should be paid attention to when applying NPK compound fertilizer?

There are different concentrations of compound fertilizer, we should pay attention to choose the appropriate concentration. At present, most compound fertilizers are distributed according to the average nutrient status of soil types and the proportion of fertilizer required by crops in a certain area. There are high, medium and low concentration compound fertilizers on the market.

Generally, the low concentration of total nutrients is between 25% ~ 30%, the medium concentration is between 30% ~ 40%, and the high concentration is more than 40%. And crops. Generally speaking, high concentration compound fertilizer is used for economic crops with good quality, less residue and high utilization rate. The concentration of compound fertilizer is high. Avoid direct contact between seeds and fertilizer. The nutrient content of compound fertilizer is high. If the seeds or seedling roots are directly contacted, the emergence of seedlings will be affected, and even the roots will be burnt. When sowing, seeds should be mixed with acupoints, and compound fertilizer should be applied in strips with an interval of 5-10 cm.

Matters needing attention in application of NPK compound fertilizer

It is necessary to pay attention to the nutrient composition of compound fertilizer with different proportion of raw materials. Different brands and concentrations of compound fertilizer use different raw materials, which should be selected and used according to the types of soil and crops. The compound fertilizer containing nitrate is not suitable for leaf vegetables and paddy fields. It is not suitable to use compound fertilizer containing ammonium ion, potassium chloride or chloride ion in saline alkali soil, potassium sulfate in crops or saline alkali soil, and potassium sulfate in paddy field and acid soil, otherwise it will reduce fertility and even poison crops.

The compound fertilizer containing two or more kinds of large elements is easy to volatilize or lose with the rain, and the phosphorus and potassium are fixed by the soil, especially the mobility of phosphorus in the soil is small, and it is not easy to be absorbed. The crop root system is on the surface, which is not conducive to deep root system. The drought condition in the fertilizer can not be dissolved, and it is worse in the development, so the compound fertilizer should go deep into the soil.

What does corn need to fertilize?

Each kilogram of corn needs 2.5 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, 2.0 kg of potassium oxide and 1:0.48:0.8 of nitrogen, phosphorus and potassium. With the increase of output, the demand for fertilizer increases.

What is the difference between nitrogen deficiency and iron deficiency in peanut?

Nitrogen deficiency will lead to plant Dwarfing and yellowing, and iron deficiency will lead to yellowing of upper new leaves of peanut.
What are the symptoms of phosphorus deficiency?

The growth of root system is not good, the plant is short, and the stems and leaves are purplish red.

What are the symptoms of potassium deficiency?

1. Improve soil fertility. After applying organic fertilizer to soil, organic matter can effectively improve soil physical and chemical properties and biological characteristics, solidify soil, enhance soil fertility and buffer capacity, and create good soil conditions for crop growth.

2. Increase production and improve quality. Organic fertilizer is rich in organic matter and a variety of nutrients, providing nutrients for crops. The decomposition of organic fertilizer can provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances, which can promote crop growth and improve the quality of agricultural products.

3. Improve fertilizer utilization rate. Organic fertilizer contains many kinds of nutrients, but its relative content is low and its release is slow. However, chemical fertilizer has high nutrient content, less composition and fast release. The organic acids decomposed by organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and improve fertilizer utilization rate. Want to make your own organic fertilizer?
