NPK Sensors: Measuring Fertilizer Efficiency and Reducing Environmental Impact

NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K)—the three core nutrients every plant needs. Nitrogen boosts leafy growth, phosphorus supports strong roots and flowering, and potassium improves overall plant health and resistance to stress.

Traditional soil testing can be time-consuming, but NPK sensors offer fast, on-the-spot results. They help farmers know exactly what their soil needs, avoiding guesswork and unnecessary fertilizer use.

Our innovative screen printed electrode uses electrochemical sensing to detect NPK levels with high sensitivity. This flexible, low-cost sensor can be embedded in handheld devices or in-field systems, making it perfect for real-time, precision agriculture.

With our technology, farmers can:

• Apply the right nutrients at the right time

Boost crop yields

Cut fertilizer costs

Protect the environment from nutrient runoff and pollution

Smarter farming starts with better data—and our screen printed electrode makes that possible.
