Fertiliser applied evenly and at the required rate can provide economic benefits to farmers and reduce adverse environmental impacts.
The Spreadmark Code of Practice for the Placement of Fertiliser in New Zealand enables farmers and growers to get the best value for their fertiliser dollar.
Spreadmark is a fertiliser spreading accreditation scheme that registers fertiliser-spreading companies with certified spreading machinery, trained operators and audited quality management systems. It is run in conjunction with Fertmark, the fertiliser quality assurance scheme.
The importance of evenness of spread has been highlighted in a Fertiliser Association funded study undertaken by Lincoln Technology, AgResearch and Agriculture New Zealand which shows that patchy fertiliser distribution can significantly affect paddock productivity.
