Why Choose Osflo?
Osflo BioGro‑approved fertilisers are built for long-term performance, not just a quick fix.
Our organic-based blends deliver nitrogen alongside the organic matter your soil needs to thrive.
By feeding the soil biology and improving structure, Osflo helps build resilient, productive soils over time.
Â
Osflo contains a rich balanced supply of all essential elements to promote and sustain healthy plant growth.
Osflo contains high levels of organic matter which sustains and improves the physical, chemical and biological soil health.
Some of the nitrogen in Osflo is immediately available for boosting growth. The remaining nitrogen is released slowly to give long lasting nutrition to the plants and the environment.
Osflo products are built around a circular economy — designed to reduce waste, minimise pollution, and put nutrients back into the land rather than taking from it
Regular use of Osflo provides an excellent environment for earthworms and promotes healthy soil. Increased micro-organism activity improves nutrient utilization and helps plants establish deeper rooting systems.
Osflo is Fertmark registered, an independent quality assurance programme for fertiliser companies in New Zealand. It means when you buy from us, you know what you’re getting.
Osflo is BioGro certified, meaning it’s a verified input into certified organic farming systems. If you’re farming to organic standards, we’ve got you covered.
Good soil looks after itself. The organic matter in Osflo products improves your soil’s ability to retain moisture — so when the dry comes, your land is better placed to handle it.
Osflo products are formulated to sustain and improve yields across both cropping and pastoral systems. Our blend contains all the essential elements and nutrients plants need — nothing missing, nothing wasted.
