The national standard for compound fertilizer GB / T 15063-2020 drafted by Liaoning JINDA fertilizer Co., Ltd. as the main drafting unit is approved by the State Administration of market supervision and the State Standardization Administration Committee and will be implemented from June 1, 2021.

The new standard modifies the name and reference of "compound fertilizer (compound fertilizer)" in the original standard GB / T 15063-2009 to "compound fertilizer". Secondly, the indexes and determination methods of nitrate nitrogen, medium and trace elements are added, and sulfur, calcium, magnesium and other medium and trace elements are allowed to be marked on the fertilizer package.

Of which:

1. Nitrate nitrogen detection requirements shall be ≥ 1.5%;

2. Single medium element mainly detects three items: available calcium, available magnesium and total sulfur. Both available calcium and available magnesium are required to be ≥ 1%, and total sulfur is required to be ≥ 2%;

3. If the product is marked with trace elements, the contents of copper, iron, manganese, zinc, boron and molybdenum can be detected. The content of molybdenum is required to be no more than 0.5%, and that of other single trace elements should be no less than 0.02%.

This participation in the drafting and formulation of national standards is another contribution by Liaoning JINDA fertilizer Co., Ltd. to the orderly development of the fertilizer industry and guide the industry to take the road of healthy and green development after participating in the drafting and formulation of the national standard "chelated fertilizer containing chelated trace element compound fertilizer (compound fertilizer) chelated fertilizer" in 2018, At the same time, it marks another new breakthrough of Liaoning JINDA fertilizer Co., Ltd. in the field of agricultural materials, which not only improves the company's core competitiveness, but also helps to promote industrial technological progress and standardize industrial market standards.

As a national high-tech enterprise and a national key leading enterprise in agricultural industrialization, Liaoning JINDA Fertilizer Industry Co., Ltd. has been "changing the traditional agricultural fertilization mode, driving scientific and reasonable fertilization, serving modern agriculture, giving crops a reasonable diet, improving crop immunity, reducing crops' dependence on chemical fertilizers and pesticides, realizing zero growth of chemical fertilizers and pesticides and improving the quality of agricultural products, With a sense of mission and responsibility of "ensuring food security and allowing farmers to continuously increase production and income", adhering to the R & D concept of "the problem of soil and plants is the subject of R & D", and integrating the enterprise development objectives and missions into the national agricultural development strategy, it has successively cooperated with the Chinese Academy of Agricultural Sciences China Agricultural University and others jointly established "high-tech development and promotion base" and "national postdoctoral scientific research workstation", cooperated with SGW company in scientific research, and jointly tackled key problems in the upgrading of chelating compound fertilizer technology. In 2021, the activated humic acid multi-element chelate Hefei and mineral source fulvic acid five in one super energy chelate Hefei products independently developed by the company were comprehensively upgraded, making outstanding contributions to the national innovation system and mechanism to promote the green development of agriculture.
