While nutrient resources and budgets are more limited than ever before, the demands we place on our land don’t let up.

With a solid understand and respect for Dairy Farming under our belts, we have developed some of the most powerfully effective nutrient products that New Zealand pastureland has ever seen.

As just one example, we now have the most powerfully effective Dicalcic Phosphate product on the NZ market – Dical12.

Our Dairy Farming customers choose our fertilisers because – number one – they deliver better nutrient efficiency. Along the way, they often save money, time and hassle, and prove less harmful to the environment as well.

Invite one of our team to your farm and see how we do things differently. We don’t just measure the chemistry of your soil and plants. We analyse soil physicality and biology, and we take the time to truly understand the way you run your farm – your approach, your systems and your goals. We then create a custom fertiliser plan that fits your specific needs and requirements.

On an on-going basis, your local consultant offers you both technical excellence and personalised one-to-one service.

Fertco fertilisers and products appropriate for Dairy Farms include:


“I'm spending less on my fertiliser than I have been and we're growing more grass! We're saving money!! Form your own opinion...”
