Dr. Russell Sharp reviews Nordetect’s upcoming handheld tester that measures nitrogen, phosphorus, potassium, calcium, magnesium and sulfur in fertigation streams using a patented agrochip plus spectrophotometry, delivering lab-level results in about three minutes instead of days.
The episode explains how the device could enable real-time nutrient monitoring, integrate with specialist software, help growers verify fertilizer claims, and potentially expose diluted or mislabelled products; it is not yet on sale but personalised demos are available.
