The industry standard "Compound Fertilizer (Compound Fertilizer) Containing Chelated Trace Elements" (HG / T5331-2018) was first released and publicized. The standard will soon be officially released and implemented, which means that China's compound fertilizer (compound fertilizer) products There are big adjustments. The standard is an effective supplement to the content of the compound fertilizer (compound fertilizer) label in GB18382-2001. Once implemented, the label of the compound fertilizer (compound fertilizer) in China will allow the identification of trace element content.

 

1. Breakthrough in standards

 

Package indicates the content of chelated trace elements

 

In view of the problem of labeling medium and trace elements in the compound fertilizer (compound fertilizer) industry that has been discussed, the introduction of this standard has further improved the compound fertilizer (compound fertilizer) that has undergone technological progress in the past 20 years. .

 

This standard is applicable to compound fertilizers (compound fertilizers) containing chelated microelements, including one or more of nitrogen, phosphorus, and potassium as nutrients containing one or more of zinc, copper, iron, and manganese. Kind of ternary or binary solid fertilizer.

 

2. The standard will be implemented

 

Disputes focus on four major issues

 

1. The problem of content. The content requirement of the chelated trace element is: the chelated trace element is greater than or equal to 150 mg / kg. This content is very low. If the current detection method is used for detection, there may be a large error. The difficulty of detection may bring certain difficulties to law enforcement in the future.

 

2. The problem of "effective form", the standard defines "chelation", but the effective form of trace elements in fertilizers does not stop there.

 

3. The standard is only applicable to solid fertilizers. Compound fertilizers are both solid and liquid, and fairness should be considered.

 

4. The standard does not specify an upper limit for the addition of trace elements. In fact, although trace elements are good, they are mostly harmful.

 

Although there is still some controversy about the standard within the industry

 

But there is no denying the practical significance of setting this standard!

 

In recent years, the amount of chemical fertilizers in China has increased sharply, but trace elements have been rarely used. Agricultural economic benefits and increased production are constrained by trace element shortages. Recognizing this problem, some companies hope to add trace elements to conventional compound fertilizers or compound fertilizers. However, due to the restrictions on the content and requirements of fertilizer labels, companies are unable to identify trace element content, and companies that do not add trace elements take advantage False propaganda claims that many trace elements are added to the fertilizers it produces. This phenomenon not only leads to unfair competition among enterprises, but also harms the interests of farmers, and it also has an adverse impact on agricultural production.

 

Comprehensive consideration: The addition of trace elements to compound fertilizers (composite fertilizers) is not only the need for the development of the industry but also for the development of agriculture in China. The promulgation of this standard will promote China's compound fertilizer (compound fertilizer) industry to pay more attention to the integration and development of a large number of elements and trace elements.
