N spread testing

MANUFACTURERS, importers and suppliers of straight nitrogen fertilisers have been invited to submit products for 1995 testing under the Fertiliser Manufacturers Association Spread Pattern rating scheme.

Companies whose products achieve an SP rating are permitted to apply the SP logo to their fertiliser. Last year 10 products were tested, of which six achieved the top SP5 rating. Cost of assessment is £1000 for a 1t sample. &#42
