Monitor nitrate and nitrite levels in farm irrigation, hydroponic nutrient solutions, and soil runoff with quick, reliable Indigo® Nitrite-Nitrate test strips.
Nitrate and nitrite levels are key indicators of nitrogen availability and nutrient balance in agricultural and hydroponic systems. Indigo® Nitrate-Nitrite Test Strips provide a fast, practical way to monitor irrigation water, hydroponic nutrient solutions, and runoff before excess nitrogen affects crop health or system performance. Simple dip-and-read testing allows growers to make timely fertilizer and nutrient adjustments without instruments, reagents, or laboratory delays.
These nitrate and nitrite test strips are widely used in field agriculture, controlled-environment hydroponics, and greenhouse production to support fertilizer optimization, nutrient efficiency, and environmental stewardship. Ideal for routine screening and process checks, they help identify nitrate accumulation, incomplete nitrification, and nutrient losses that contribute to crop stress or off-site pollution. Common applications include irrigation water testing, nutrient solution management, leachate and runoff screening, and sustainability or extension education programs.
| Method | Advantages | Limitations |
|---|---|---|
| Nitrate/Nitrite Test Strips | Fast, inexpensive, portable; ideal for quick checks in fields or greenhouses. | Approximate results; less precise than digital sensors. |
| Electronic Probes | Continuous monitoring, higher precision; integrates with automated hydroponic systems. | Expensive, requires calibration and maintenance. |
Lot-specific documentation, defined shelf life, and consistent manufacturing support use in commercial farming operations, research trials, and sustainability programs where repeatability, traceability, and QA review are required—even for rapid field screening methods.

This Indigo® test strip indicates the presence of nitrate & nitrite. Results for ranges shown below can be read in 30 seconds.
No, they test nitrate and nitrite in water. To check soil, prepare a water extract by mixing soil with distilled water and filtering.
Weekly during fertilization periods is recommended; more frequently if crop stress or algal growth is observed.
Test strips are excellent for field screening. For official compliance, lab or probe-based methods may be required.
Yes, though high salt concentrations may slightly affect readings. Consistency in testing conditions helps ensure accuracy.
