3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Water-soluble fertilizers
The liquid or solid fertilizers which, after being dissolved or diluted in water, is used for irrigation and fertilization, foliar fertilization, soilless cultivation, 2.0% or 20 g/L, the absolute value of the negative relative deviation,
BETWEEN the measured value AND the indicated value, of each element
shall not exceed 40%. When the indicated value of a single medium-
nutrient is greater than 2.0% or 20 g/L, the absolute value of the negative relative deviation, BETWEEN the measured value AND the indicated value, of each element shall not exceed 1.0% or 10 g/L.
4.5 If trace-nutrients are added to the product, it shall indicate the content of single trace-nutrient AND the total content of trace-nutrients, which contained in the product, on the package label.
- The content of trace-nutrients refers to the sum of the content of copper, iron, manganese, zinc, boron, molybdenum. The product shall contain at
least one of these trace-nutrients.
- The content of a single trace-nutrient is not less than 0.05% or 0.5 g/L. The content of molybdenum element is not higher than 0.5% or 5 g/L.
- For the content of a single trace-nutrient, if it is less than 0.05% or 0.5 g/L, it is not included into the total content of the trace-nutrients.
- When the indicated value of a single trace-nutrient is not greater than 2.0% or 20 g/L, the absolute value of the negative relative deviation, BETWEEN the measured value AND the indicated value, of each element shall not
exceed 40%. When the indicated value of a single trace-nutrient is greater than 2.0% or 20 g/L, the absolute value of the negative relative deviation, BETWEEN the measured value AND the indicated value, of each element
shall not exceed 1.0% or 10 g/L.
4.6 If the solid water-soluble macronutrient fertilizer product is in the form of granules, the particle size (1.00 mm ~ 4.75 mm or 3.35 mm ~ 5.60 mm) shall be ??? 90%. For the particle size of products, which has special shapes or larger particles (except powder), it can be determined, through negotiation, between the supplier and the buyer.
