Water-soluble macronutrient fertilizers
1 Scope
This standard specifies the requirements, test methods, inspection rules,
marking, packaging, transportation, storage of water-soluble macronutrient
fertilizers.
This standard is applicable to liquid or solid water-soluble fertilizers, which are
produced and sold within the territory of the People’s Republic of China; use
macronutrient of nitrogen, phosphorus, potassium as the main components;
can be added with appropriate amount of medium-nutrient or trace-nutrient.
This standard does not apply to fertilizer products, that have mandatory or
recommended national or industry standards, such as compound fertilizers
AND solid fertilizers which are made only by chemical methods.

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.
5 Test method
5.1 Appearance
It is determined by visual inspection.
5.2 Determination of total nitrogen content
It is determined according to the provisions of NY/T 1977.
