Is the chemical fertilizer cheap or expensive? What's the difference?

When it comes to spring ploughing in another year, all kinds of chemical fertilizers fill the market with different proportions, prices vary widely, and even great disparities in prices. At this time of year, farmers struggle with chemical fertilizer. Which one should they buy? Buying expensive ones is afraid of losing money, buying cheap ones is afraid of having no effect, and buying those with moderate prices does not know whether they are true or false.

I. factors determining the price of chemical fertilizer

The composition of chemical fertilizer is mainly the content of nitrogen, phosphorus and potassium. With the same proportion of fertilizer, there is little difference in cost. The fertilizer production process of big brands is strict, the production cost will be higher, but the use effect is also better. If the price of the same ratio of chemical fertilizer varies greatly, 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 proportion. Some manufacturers are short of 5-15 pieces, each content about 50 yuan per ton, 5 250 yuan, the cost difference of each bag is about 15-45 yuan.

Second, why are some small manufacturers qualified in chemical fertilizer tests, and the prices of large manufacturers are not the same?

At present, functional departments only test N, P, K, and many small manufacturers can do a good job on the surface; famous brands and large factories also have to add various trace elements, about 300 yuan per ton, to meet the needs of high crop production.

Third, why is the effect of cheap chemical fertilizer better than that of famous-brand chemical fertilizer?

Ammonium bicarbonate took effect on the same day and the fertilizer effect period was only 15 days, while ammonium chloride took effect in three days and the fertilizer effect period was 25 days. Urea, effective in seven days, fertilizer effective period of 45 days, compound fertilizer effective in ten days, fertilizer effective period of 90 days.

Fourth, how to choose the speed of fertilizer effect?

Quick-acting chemical fertilizer is absorbed by crops and has a quick effect. It is generally used as topdressing and can also be used as base fertilizer. Slow-acting fertilizer and controlled-release fertilizer have long-lasting effect and are more suitable to be used as base fertilizer.

Fifth, expensive is cheap, cheap is expensive?

The price of chemical fertilizer should be measured not only by the price of a bag, but by the amount of fertilizer used per mu. Cheap chemical fertilizer is 100 jin per mu, 100 yuan per mu. Famous brand chemical fertilizer is 70 jin per mu, 90 yuan per mu, which is a good fertilizer that can really save money. If you have used inferior chemical fertilizer, you will catch up with it immediately, and the effect will be better than that of the previous one. If you use good chemical fertilizer for three years in a row, even if you don't use chemical fertilizer for one year, the output will not be low.

What kind of fertilizer is cheap and good?

Experts suggest that it is best to buy brand chemical fertilizer, the quality is guaranteed. The same big brands, the same ratio of fat, manufacturers' advertising investment, marketing channels are different, the price will be different. After layers of distribution, large-brand chemical fertilizer is more expensive in the hands of farmers, and it often costs more than ten yuan per bag to buy brand chemical fertilizer. However, now that there is an e-commerce sales platform such as "Xinnongbao", if the chemical fertilizer of large brands is sold directly to farmers, they can buy affordable and assured brand fertilizer, and they can provide technical services through local service stations, so that farmers can really get real benefits. this is the best channel to buy agricultural materials in the future.
