Soil nutrient sensor
Track nutrients (N, P, K) in soil for more precise fertigation. Less waste, better performance.
What it measures and why it matters
Helps monitor levels/trends of N, P and K to make fertilization decisions with more criteria: apply what’s needed, when it’s needed, and reduce excesses.
How it works
The sensor estimates availability of key nutrients (nitrogen, phosphorus, potassium) in soil through electrochemical or spectrometric techniques, enabling near real-time adjustments.

Frequently asked questions
Does it replace a lab analysis?
No — it complements it. Labs give very precise absolute values at a point in time. The sensor provides continuous trends to adjust management day to day.
How do I use it to adjust fertigation?
Monitor NPK trends. If N drops quickly, increase input; if it accumulates, reduce. Fine adjustments based on real demand, not fixed recipes.
What if my soil is very heterogeneous?
You’ll need more than one sensor to capture variability. Or combine with zoning (NDVI, soil maps) to place representative sensors for each zone.
Does it work in all soil types?
Yes, though accuracy can vary with texture, organic matter and pH. Trends are generally more useful than exact absolute numbers.
Does it need soil-specific calibration?
Some models do, others use general calibrations. In any case, comparing to initial lab analyses helps contextualize readings.
Is it useful for precision agriculture?
Absolutely. It’s a key tool: apply variable nutrients based on real spatial and temporal needs.
How often does it measure?
Depends on configuration, but typically hourly or several times per day, enabling weekly dynamics and response to fertilization.
Should I combine it with NDVI imagery?
Yes, recommended. NDVI shows crop vigor; NPK shows nutrient availability in soil. Together they explain deficiencies and excesses better.
