H5N1 in New Zealand: Plain Answers for Farmers Using Osflo Products
Start with a soil test. Our technical specialists work through the results with you to build a programme around your soil, your paddocks and your production goals. That might mean Osflo our composted fertiliser on its own – or a custom blend of Osflo and conventional products where additional nutrients are needed. We spread locally and transport in bulk across the North Island.

Soil nutrient specialists
We understand what’s happening below the surface — soil structure, nutrient availability, biology, and compaction — and how it affects performance above ground. Every recommendation is grounded in data and real farm experience.
On-farm agronomy support
We’re there when conditions change, seasons shift, and decisions matter. You get practical, independent advice from people who know your region and your system.
Testing that actually means something
Soil tests tell you what’s in the ground. Herbage tests show what your plants are taking up. Together, they give you the full picture — and the right next step.
Custom fertiliser plans
No two farms are the same, so neither are our plans. We tailor nutrient strategies to your soil, crops, stocking rate, and long-term goals — reducing waste and improving performance.
