Water-Soluble Fertilizers Containing Humic-Acids
1 Scope
This Standard specifies the technical requirements, test methods, inspection rules,
marking, packaging, transportation and storage of water-soluble fertilizers containing
humic-acids (macro element type) and water-soluble fertilizers containing humic-acids
(trace element type).
This Standard is applicable to mineral humic acids produced and sold in the People’s
Republic of China, with a proportion suitable for plant growth; adding appropriate
amounts macro elements such as nitrogen, phosphorus, potassium; or trace elements
such as copper, iron, manganese, zinc, boron, and molybdenum; so that make the
liquid or solid water-soluble fertilizers.

3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
3.1 Water-soluble fertilizers
It is a liquid or solid fertilizer that is dissolved or diluted in water and used for irrigation
and fertilization, foliar fertilization, soilless cultivation, soaking seeds and roots.
3.2 Mineral humic acids
It is a mixture of amorphous polymer compounds that contains benzene nuclei,
It shall be performed according to the provisions of NY/T 1978.
5.21 Determination of cadmium content
It shall be performed according to the provisions of NY/T 1978.
5.22 Determination of lead content
It shall be performed according to the provisions of NY/T 1978.
5.23 Determination of chromium content
It shall be performed according to the provisions of NY/T 1978.
6 Inspection Rules
6.1 The products shall be inspected by the quality supervision department of the
enterprise; and the manufacturer shall ensure that all the sold products meet the
requirements of this Standard. Each batch of products shall be accompanied by a
quality certificate, and its content shall be implemented in accordance with the
provisions of the marking.
6.2 The product is inspected by batch, taking one batch of ingredients as a batch; and
the maximum batch quantity is 50t.
6.3 Sampling of solid or bulk products shall be carried out in accordance with the
provisions of GB/T 6679. Sampling of liquid products shall be carried out in accordance
with GB/T 6680.
6.4 Place the sampled product in a clean, dry container and mix quickly. Take 600 g of
solid sample or 600 mL of liquid sample; divide them into two clean, dry containers,
seal and label them, indicating the name of the manufacturer, product name, batch
number or production date, sampling date, and sampler’s name. One bottle is used for
product quality analysis, and the other bottle shall be kept for at least two months for
re-inspection.
6.5 After multiple fractionation of the solid sample, take out about 100 g, quickly grind
it until all of it passes through a 0.50 mm sieve (if the sample is wet, it can pass through
a 1.00 mm sieve), mix well; and place it in a clean, dry container for determination.
6.6 After shaking the liquid sample for several times, quickly take out about 100 mL of
it; and place it in a clean and dry container for determination.
6.7 When the manufacturer performs the exit-factory inspection, if one or more
indicators of the inspection results do not meet the requirements of this Standard, re-
sample from the doubled sampling batch for re-inspection. If one or more indicators do
requirements of the trace element content. When the marked-value of a single
trace element is no greater than 2.0% or 20 g/L, the absolute value of the positive
and negative relative deviation between each measured value and the marked
value shall be no greater than 40%. When the marked-value of a single trace
element is greater than 2.0% or 20 g /L, the absolute value of the positive or
negative deviation between each measured value and the marked value shall be
no greater than 1.0% or 10 g/L.
7.2.3 The marked value of the sulfur content. When the marked-value of sulfur element
is "sulfur (S) ≤ 3.0% or 30 g/L", its measured value shall be no greater than 3.0% or 30
g/L. When the marked-value of sulfur element is greater than 3.0% or 30 g/L, the
absolute value of the positive or negative deviation between the measured value and
the marked value shall be no greater than 1.5% or 15 g/L.
7.2.4 The marked value of the chlorine content. When the marked-value of chlorine
element is "chlorine (Cl) ≤ 3.0% or 30 g/L", its measured value shall be no greater than
3.0% or 30 g/L. When the marked-value of chlorine element is greater than 3.0% or 30
g/L, the absolute value of the positive or negative deviation between the measured
value and the marked value shall be no greater than 1.5% or 15 g/L.
7.2.5 The marked-value of sodium content. When the marked-value of sodium element
is "sodium (Na) ≤ 3.0% or 30 g/L", its measured value shall be no greater than 3.0%
or 30 g/L....
