A new New Zealand study has linked nitrate levels in drinking water to premature births, but does that tell the whole story?

In this episode of EcoFarm Aotearoa, we unpack the latest media reports surrounding nitrates and explore what they may be overlooking. Campbell questions why the conversation always seems to stop at identifying the problem, rather than addressing the biological systems that can solve it.

The discussion covers how healthy soils naturally cycle nitrogen, why cyanobacteria are central to this process, and how improving soil biology can reduce nitrate leaching while increasing farm profitability. We also dive into the importance of mineral balance, the relationship between nickel, selenium, copper and zinc, and why testing and measuring should replace assumptions.

Rather than simply monitoring environmental issues, this episode looks at practical, evidence-based ways farmers can restore healthier soils, cleaner water and more resilient farming systems.

We Discuss:

• The latest nitrate and drinking water research
• Why correlation isn't the same as causation
• How healthy soil biology reduces nitrate leaching
• The role of cyanobacteria in nitrogen cycling
• Why test and measure beats guesswork
• Mineral interactions: nickel, selenium, copper & zinc
• Improving livestock nutrition naturally
• Why profitability and environmental outcomes can improve together
