Turn challenges into opportunities when you choose our innovative cropping products and customised service for arable farming in New Zealand
We understand that managing soil nutrients is crucial for successful cropping. You need maximum yields while keeping an eye on nutrient wastage and environmental impact.
Our cropping fertiliser blends are designed to do exactly that. They include controlled release, ‘less-leaky’, formulations. Many of them are also seed-safe. That means reduced nutrient loss, less application effort, and better return on investment. Sow and fertilise your crop at the same time, then shut the gate and watch it grow!
Contact your local Field Rep for personalised service and crop-specific advice.

The Fertco 2-Step Maize Programme
– Powered by NSmart –
A proven performer, our 2-step maize programme delivers everything to nutrient-hungry maize crops in two simple steps, not the traditional three: once before planting and then again at sowing time. Less N loss, less effort, and higher yields.
