In the spring ploughing year, a variety of fertilizers are piled up in the market, and the ratios are varied. The prices vary widely, and even the price is very different. At this time of the year, farmers are entangled in fertilizers. Which one is good to buy? Buying expensive ones is afraid of losing money. If you buy cockroaches, there is no effect. If you buy a moderate price, you don’t know the true and false.
First, the factors that determine the price of fertilizer
The composition of chemical fertilizers is mainly the content of NPK. The same ratio of fertilizer, the cost difference is not big. The big brand's fertilizer production process is strict, the production cost will be higher, but the use effect is also better. If the price of fertilizer is also very different, it can only show that the cheap fertilizer content is not enough. At present, due to the difficulty of supervision, many small manufacturers do have insufficient ratios. Some manufacturers lack the content of 5-15, each content is about 50 yuan per ton, 5 250 yuan, the cost difference of each bag is about 15-45 yuan.
Second, why do some small manufacturers have qualified chemical fertilizers, and the prices of large manufacturers are not the same?
Now the functional department only tests N, P, and K. Many small manufacturers can do a good job on the surface article; the famous brand big factory must add various trace elements, about 300 yuan per ton, to meet the needs of high crop yield.
Third, why is the effect of cheap fertilizers better than brand-name fertilizers?
The ammonium carbamate is effective on the day, the fertilizer effect period is only 15 days; the ammonium chloride is effective for three days, and the fertilizer effect period is 25 days. Urea, effective in seven days, the fat effect period is 45 days; the compound fertilizer is effective in ten days, and the fertilizer effect period is 90 days.
Fourth, how to choose fertilizer efficiency?
The quick-acting fertilizer is absorbed by the crop, and it has a quick effect. It is generally used as a top dressing and can also be used as a base fertilizer. Slow-acting fertilizers and controlled-release fertilizers have long-lasting effects and are more suitable for use as base fertilizers.
Five, expensive is è´±, è´± is expensive?
The price of chemical fertilizer cannot be measured by the price of a bag, but should be measured by the amount of fertilizer used per acre. Cheap fertilizers are 100 kg per mu, 100 yuan/mu. A brand-name fertilizer of 70 kg per mu, 90 yuan / mu, really save money or good fertilizer. If you use too bad quality fertilizer, you can immediately catch up with the fertilizer. The effect is not as good as the original fertilizer. Continuous use of fertilizer for three years, not only a year without fertilizer, the output will not be low.
Therefore, when you choose fertilizer, don't blindly pursue the price, you must pay attention to the price!
