Compound Fertilizer Price in 2022

1. Many fertilizers are cheap, but the effect is good after use. Why?
Now most manufacturers increase the nitrogen content, reduce the potassium content, or even do not add it.

For example, the content of 15-15-15 45% is made into 20-10-5 35%. After use, the seedlings are strong. Later, without fertilization, the final yield cannot be increased.

2. Why is the effect of cheap fertilizer better than that of famous brand fertilizer?

The effect of ammonium bicarbonate is immediate and valid for 15 days; Ammonium chloride takes effect in 3 days, the fertilization period is 25 days, and there is no fertilization in the later stage of growth period. Urea takes effect in 7 days and the fertilization period is 45 days. The effect of compound fertilizer can be seen in ten days, and the fertilization period is 90 days.

3. How to understand that cheap is expensive and expensive is cheap?
As for cheap fertilizer, it needs a bag of weight, 50kg per mu, and the cost is 100 yuan / mu. Famous brand fertilizer is 35kg per mu, 90 yuan / mu, which is more cost-effective.

4. Why does the production capacity not increase after using famous brand fertilizer?

The principle of nutrient return is how much food you receive and how much nutrients you need to absorb from the soil in order to return how much high-quality fertilizer.

In other words, if you use low-quality fertilizer for three consecutive years, you can catch up with good fertilizer immediately, which is stronger than the original and can match the original good fertilizer. If you use good fertilizer for three consecutive years, even if you don’t have fertilizer for one year, the output will not be low.

8. What are the four elements of sulfur?
The three elements are nitrogen, phosphorus and potassium. Now the national standard, if the amount of elements is more than four, the content can be marked. If the sulfur content is 7%, it is the four elements necessary for crop growth, that is, farmers spend the same money to buy phosphorus, phosphorus and potassium, as well as sulfur, which is cost-effective

9. What is the difference between controlled fertilizer and compound fertilizer?

The first generation of controlled-release fertilizer is resin or sulfur coated controlled-release fertilizer; The second generation is an intelligent release factor directly added to fertilizer. The fertilization period can reach 120 days and the utilization rate can reach 70 days.
