Detailed Explanation of the Standard for Water-Soluble Secondary Element Fertilizers
Secondary element content a, g/L≥100; water-insoluble matter content, g/L≤50; pH (1:250 dilution) 3.0-9.0; moisture content (H2O) %≤3.0; secondary element content refers to calcium content or magnesium content or the sum of calcium and magnesium content, with a content of not less than 1.0%; both calcium and magnesium elements shall be counted in the secondary element content, while sulfur element is not counted in the secondary element content and is only indicated in the labeling.
Product features of water-soluble secondary element fertilizer:
1. This product is a fully nitrate-nitrogen, 100% water-soluble secondary element fertilizer. Used in combination with macro element fertilizers, it remedies physiological diseases caused by nutrient deficiencies in crops, enabling crops to absorb more comprehensive nutrition. It is a golden partner for the macro elements N, P and K.
2. According to CCTV's "Global Agriculture" report, using only nitrogen, phosphorus and potassium cannot fully supplement nutrition for crops; they must be used in combination with secondary elements such as calcium and magnesium to achieve high quality and high yield. After this product is applied to the soil, it can make the crop roots well developed, the stalks thick, and the leaf color dark green, and improve the utilization rate of nitrogen, phosphorus and potassium in the soil.
3. The calcium and magnesium ions in this product can not only provide sufficient calcium and magnesium for the soil, but also improve the physical and chemical properties of the soil, playing a protective role for the soil. In sustainable agricultural development, it has advantages unmatched by other chemical fertilizers and will have more far-reaching significance for environmental protection.
4. This product is a safe and environmentally friendly fertilizer that contains no hormones and leaves no residue. It guarantees the safety of crop leaves, flowers and fruits, is non-toxic to the environment and crops, and is an environmentally friendly green fertilizer.
