Some farmers always think that the role of chemical fertilizers is similar when purchasing fertilizer products. There is no difference between expensive and glutinous rice. Therefore, when choosing fertilizers, I always want to buy cheap fertilizers. But is there really no difference between expensive and expensive fertilizers? Let's take a look at the difference between the richness of fertilizer products and the difference in fertilizer products with similar names.
First, is it cheap and expensive?
Different, the brand name of the big factory is sufficient, the content of each product is only high, and the national standards are strictly enforced.
Many manufacturers lack the content of 3-15, each content is about 50 yuan per ton, 5 250 yuan, about 15 yuan per generation.
Second, a lot of fertilizer prices are low, and the performance after use is also good. Why?
Now most manufacturers are raising the nitrogen content, reducing the potassium content, or even not, for example: 15-15-1545% content made of 20-10-535% content, Miao Qi Miao Zhuang, can be late De-fertilization, the final output will not go up.
Third, why is the effect of cheap fertilizers better than brand-name fertilizers?
The ammonium bicarbonate is effective on the same day, the fertilizer effect period is 15 days; the ammonium chloride is effective for three days, the fertilizer effect period is 25 days, and the fertilizer is degraded later. Urea, effective in seven days, fat effect period of 45 days. The compound fertilizer is effective for ten days, and the fertilizer effect period is 90 days.
Fourth, you are expensive, expensive is awkward, how do you say this?
Cheap fertilizers are 100 kg per mu, 100 yuan/mu. Famous brand fertilizers 70 kg per mu, 90 yuan / mu, a real fertilizer to save money.
5. Why do you think that the production of brand-name fertilizers has not improved?
The principle of nutrient return, how much nutrients you collect from the soil, how much nutrients are extracted from the soil, and how much fertilizer is returned.
That is to say, continuous use of the inferior chemical fertilizer for three years, immediately chasing the fertilizer, stronger than the original, comparable to the original good fertilizer, for three consecutive years of good fertilizer, not only a year without fertilizer, the output will not be low.
6. Why do some small factories have qualified chemical fertilizers and are not the same as the prices of big factories?
Now the functional department only tests N, P, and K. The small factory will do a good job on the surface article; the famous brand factory will also add various medium and trace elements to about 300 yuan per ton to meet the needs of high crop yield.
7. Is there any difference between potassium sulfate type and potassium sulfate?
Potassium sulphate type is produced by dechlorination of potassium chloride in the production process of compound fertilizer. It is produced by potassium sulphate. The chloride ion is about 3-5%. The potassium sulphate compound fertilizer is pure potassium sulphate. The chloride ion is below 3 Suitable for all kinds of crops.
8. Is there any difference between compound fertilizer and compound fertilizer?
Compound fertilizer: high tower granulation, acid granulation, spray granulation, high utilization rate of 60%.
Compound fertilizer: It is drum granulation and disc granulation, and the utilization rate is 40% lower.
What is the ninth and four major elements of sulfur?
The three major elements are nitrogen, phosphorus and potassium. Now the national standard, with more than four medium-sized elements, can be labeled. Containing 7% of sulfur, it is the four elements necessary for the growth of crops, that is, farmers spend the same money to buy three elements of nitrogen, phosphorus and potassium, and also buy four elements of sulfur - affordable.
10. What is the difference between controlled release fertilizer and compound fertilizer?
The controlled release fertilizer is also a compound fertilizer. The first generation is controlled release of resin or sulfur coating. The second generation is the intelligent controlled release factor directly added to the fertilizer. The fertilizer efficiency period can reach 120 days, and the utilization rate is as high as 70.
