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.
Mobile nutrients such as nitrogen or potassium are most effectively used when split applications of fertiliser are applied frequently during the periods of crop or pasture growth. This is usually preferable to one large application. However, crops and pastures may have short periods of very high nutrient demand and so a larger application will be required at that time.
Fertigation systems (adding nutrients in irrigation water) provide flexibility in applying nutrients to meet plant demand but regular top-dressing or side dressing of fertiliser can have similar effects, provided that there is sufficient moisture to move nutrients into the soil.
