In the two cases of disagreement with the manufacturer's declared analysis, details
were as follows-
A sample of a general fertilizer was found on analysis to have nitrogen, potash and
phosphate slightly in excess of the amounts declared by the manufacturer. Investigation showed
that this was very old stock which had been stored by the retailer for about six years, with
consequent chemical change.
A sample of Intensive Growers Mash had a protein content in excess of the declared
amount, and a warning letter was sent to the manufacturer.
