Fertiliser Quality Council (FQC)

Set up by farmers for farmers, the FQC is responsible for the  Fertmark and Spreadmark initiatives.

Using the “Marks”

The Fertmark tick guarantees that the labeled contents of the fertiliser product are correct. The Spreadmark logo gives farmers and growers assurance that the spreading company – ground or aerial – is certified to distribute the fertiliser accurately and evenly.

NZ Groundspread Fertiliser Association

Formed in 1956, the NZGFA promotes the interests of both individuals and companies involved in the distribution of bulk lime and other fertilisers.

Spreading nutrients, whether from the ground or from the air, is a highly skilled profession. Spreadmark certified companies have passed the test.
