CHECKING QUALITY OF FERTILIZERS.
Many farmers may still be unaware that the Department of Agriculture is desirous of their assistance in checking the quality of the fertilizers on the market, by the forwarding of samples by them for analysis. No fee is charged for this work, and in the event of any deficiency being found an official sample of the fertilizer will be taken from the vendor’s store by a departmental officer. This will enable legal proceedings to be taken should the results warrant it. For farmers’ samples a portion of the fertilizer should be taken from each of a number of bags, and the portions thoroughly mixed together. Finally, a portion weighing about i lb. may be put into a clean, dry tin, and posted with the invoice certificate . (or a copy of it), addressed to the Agricultural Chemist, Dominion Laboratory, Wellington.” It is essential that the invoice certificate should accompany . any. sample sent, or, if no certificate has been supplied, the name and address of the vendor and the brand of the fertilizer should be stated.
