changes are as follows.
- MODIFY the requirements for quality score of total nutrients;
- MODIFY the requirements for pH range;
- MODIFY the requirements for limit index of arsenic (As), cadmium (Cd),
lead (Pb), chromium (Cr), mercury (Hg), in products;
- MODIFY the judgment rules;
- ADD the requirements for the limit value of each single nutrient, in the total
nutrient;
- ADD the technical index requirements for organic matter;
- DELETE the technical index requirements for fineness;
- STANDARDIZE the references such as product testing methods.
This standard was proposed by AND shall be under the jurisdiction of the
Plantation Management Department of the Ministry of Agriculture.
