Feeding the world’s growing population
New Zealand’s reputation as a quality food producer is growing.
The Fertiliser Association of New Zealand promotes and encourages responsible and scientifically-based nutrient management.
Placement will also affect the degree of interaction between the fertiliser and the soil, which is particularly important where nutrients can become unavailable due to reactions with soil minerals (e.g. phosphorus fixation) or organic matter (e.g. nitrogen immobilisation).
Placement of fertiliser should conform to the Spreadmark Code of Practice for both Aerial and Ground Fertiliser Spreading.
Common options for fertiliser placement include:

For example, applications to crops, especially in horticulture, generally require more accuracy and precision than applications to intensive pastures where nutrients are continually redistributed by the grazing animals.
In deciding on the right application method, key questions to consider include:
