Fertco has the largest range of BioGro certified fertiliser products in New Zealand, and we are a major supplier to the organic kiwifruit, avocado, and citrus industries, so our expertise in organics is well established.

Because we focus on nutrient efficiency and environmental sustainability, organic products fit perfectly with our ethos. Protamin N is one such product. It includes fast, medium, and slow release nitrogen, so nutrient losses and environmental impacts are low. Additionally, it contains a high percentage of organic extractable carbon, P and K (of natural origins), and gelatine to increase root absorption, all of which stimulate plant processes and look after your soil biology (see other exciting organic products from our unique range here).

But it’s not just the organic products that fit with our Fertco values. The holistic principles practiced by organic producers also align well with what we do. When you consult us, we don’t just measure soil chemistry. We analyse soil biology and soil physicality, and consider the goals that you have for your property. Only then do we design a complete nutrient programme for you.

Soil and Herbage Testing Icon

Soil & Herbage Testing

As a science-based organisation, soil and herbage tests underpin everything that we do. We use New Zealand testing labs who provide clear, consistent results based on years of trials and regularly calibrated procedures. This provides a strong foundation for us help you develop and maintain an effective fertiliser management plan.

Quality Advice and Nutrient Budgets Icon

Quality Advice & Nutrient Budgets

At Fertco, we commit time and resources to train our people. We know that recommending the best fertiliser programme for your soil is only part of the story, so are equipped to prepare a full nutrient budget report for both efficient nutrient management and compliance purposes.

Customised Recommendations Icon

Customised Recommendations

Every property is different, and so is every farmer, so we don’t have generic ‘one-size-fits-all’ products. Although we base our recommendations on soil and herbage tests, our aim is to develop a fertiliser programme in partnership with you to suit your specific property and individual goals. Customised orders are all in a day’s work for us!

Environmentally Sustainable Products Icon

Environmentally Sustainable Products

Sourcing environmentally sustainable products is what Fertco has always been about (see About for our story). We select products that mitigate nutrient losses and test everything for contaminants and impurities. It’s equally important to us that what we source from around the world is ethically produced without polluting the local environment or involving child labour.
