Authentic compound fertilizer brands from large manufacturers (how to distinguish the authenticity of compound fertilizers)

There are many brands of compound fertilizers on the market, and both large and small manufacturers are flooding the market. Whether we choose a small factory or a well-known brand, many farmers are unsure and the prices are very expensive.

A bag of good compound fertilizer costs about 200 yuan, which is ridiculously expensive. It's okay if the price is expensive, but it would be depressing if you buy fake fertilizer.

At present, the leading fertilizer companies are:

Sinofert, Yuntianhua, Yangfeng, Sakefu, Wengfu, Stanley, Kingenta, Shikefeng, Xinlianxin, Garsili, Luxi Chemical, Salt, Hubei Yihua, Batan, Lutianhua, Kailin Fertilizer, Jinyimeng, Liuguo, China Agricultural Materials, Yanqiao, Sichuan Meifeng, Sanning Chemical, Hongsifang, Tianji, Fengxi Fertilizer, etc.

Which brand of fertilizers have you used?

This time of year is the peak season for fertilizer demand, but I learned from the agricultural supply store that in previous years many farmers had already started purchasing urea or compound fertilizers at this time.

However, this year many farmers have postponed their purchases and will wait until the reserve fertilizers are available. The reserve fertilizers must be cheaper than this fertilizer, so it would not be cost-effective to buy it at a higher price.

As for which compound fertilizer is better, I personally think that there is not much difference between them, as long as you don’t buy fake or stolen fertilizers.

However, for farmers, if they don't distinguish carefully, it is easy to buy fakes. Two years ago, a type of fertilizer like this was exposed, which harmed many farmers. This type of fertilizer is the same fertilizer no matter what kind of fertilizer you buy, but the packaging bag is changed.

For example, if we buy a compound fertilizer with 45% content, he will fill it for you in a packaging bag marked with 45% content. If you want a compound fertilizer with 3 17%, he will fill it for you in a packaging bag marked with 3 17.

If you want fertilizer produced in Hebei, he will pack it for you in packaging bags with the Hebei origin logo. In fact, these are all the same fertilizer.

When we first used this fertilizer, its shortcomings were not obvious because there must be some nutrients in the soil, and when the seeds germinate and grow two leaves, the nutrients mainly come from the seed embryo.

When problems arise in the later stages, farmers may think that there is disease or that it is time to apply fertilizer. In fact, it is the unqualified fertilizer that leads to fertilizer deficiency in the later stages, yellowing of seedlings and thin and weak plants, lack of resistance to lodging, and insufficient nutrition, which ultimately leads to a decrease in yield.

1. So how to distinguish the authenticity of fertilizer?

First of all, it is recommended to buy some fertilizers from big brands. Big brands may raise prices or hoard goods, but the quality is still no problem.

When we buy fertilizer, we must look carefully at the packaging bag. As long as the packaging bag contains the following content, there is basically no problem.

1. We can check whether there is an R logo on the trademark on the packaging bag. If not, don’t buy it.

2. We know that compound fertilizers, in addition to nitrogen, phosphorus and potassium, also contain some auxiliary materials or fillers. We also need to check whether these active ingredients are clearly marked, whether the implementation standards are correct, and the factory address and telephone number.

3. In addition to looking at the outer packaging, we also need to look at the fertilizer. Good compound fertilizer particles are relatively uniform in size and very hard. In addition, we need to break one to see if the color of the cross section is consistent from the outside to the inside. If the overall consistency is consistent, it means that the compound fertilizer is of high quality. Otherwise, the craftsmanship is poor!

2. Don’t buy the following fertilizers no matter how cheap they are

The higher the fertilizer price, the more fake fertilizers will be rampant, and some lawless elements will use low prices to attract farmers to buy. Farmers think they have found the old inventory, but in fact it is fake fertilizers. Don't be fooled!

1. When we buy urea, whether we buy white ordinary urea or colored urea, we must pay attention to the implementation mark

At present, the implementation standard of urea must be the national standard GB2440-2017, and the packaging bag must have a nitrogen content of ≥46%. Do not buy products without these two labels. Spending money is a small matter, but it is not cost-effective if it harms the crops.

2. When we mix urea, diammonium phosphate and potassium chloride as fertilizers, we must buy large-particle urea and diammonium phosphate from regular manufacturers.

The packaging must have the certification and implementation standards of diammonium phosphate, national standard GB10205-2009, with a total content of 64%, of which the nitrogen content is 18% and the phosphorus content is 46%.

This is the standard. We should not buy diammonium phosphate that is not labeled as such to avoid being cheated.

3. There are many products on the market that add additional ingredients, such as humic acid, various trace elements, etc.

However, we must remember that when we buy fertilizers, we mainly buy nitrogen, phosphorus and potassium. The total nutrients refer to the sum of nitrogen, phosphorus and potassium. If additives are also counted in the total nutrients, it is best not to buy them.

Of course, it is not that they cannot be used. Some fertilizers can indeed play a role. However, as base fertilizers, we must add them again ourselves to see if nitrogen, phosphorus and potassium can meet the needs.

4. Potassium fertilizer is relatively expensive this year. The arrival price of potassium chloride has reached 4,300 yuan. Be sure to pay attention to those with cheap prices. They can't sell it to you at a loss!

When we buy potash fertilizer, we must pay attention to the fact that we should buy potassium oxide with the K2O mark. For example, the potassium dihydrogen phosphate, potassium nitrate, and potassium chloride we commonly use are all marked with K2O. Do not buy them without this mark.

5. Do not buy fertilizers labeled with HAK or KOM. These are fake fertilizers, so don't be fooled.

6. We should not easily try new fertilizers recommended by acquaintances or agricultural supply sales staff. Even if they are good, there is no need for us to be "guinea pigs". If they are effective, they will be sold again in the second year, and it is not too late for us to buy them.

In short, fertilizers are very expensive this year, so we can wait for the fertilizer reserves to come down and see how much they cost. From the perspective of raw materials, ammonium chloride has increased by 500 yuan per ton compared to last year, ammonium phosphate has increased by nearly 1,000 yuan per ton compared to last year, and potash fertilizers have also increased by about 1,000-1,500 yuan per ton.

As the price of raw materials rises, compound fertilizers cannot be cheap. We should not be greedy and buy some inferior fertilizers.
