Test ammonia in compost and soil leachate to monitor nitrogen balance and maturity. Use fast, field-ready Indigo® 0-100 ppm ammonia test strips for sustainable soil and fertilizer management.

Indigo® Instruments 0-100 ppm ammonia test strips provide a fast, field-ready method for evaluating nitrogen behavior in compost extracts and soil leachate. Monitoring ammonia (NH3) and ammonium (NH4+) helps indicate whether nitrogen is being retained by microbial activity, converted into plant-available forms, or lost through volatilization. The simple dip-and-read format delivers clear visual results in seconds, making these strips well suited for compost maturity checks, soil fertility screening, and hands-on nutrient management without the need for laboratory equipment.

We've been selling ammonia test strips since 2014. Buy fully documented Indigo® ammonia test strips, 25 strips/vial, with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Learning Outcomes by Discipline

Learning Outcomes / Key Features Description
Understanding Nitrogen Cycling Demonstrate how organic nitrogen converts to ammonia and nitrate through microbial mineralization and nitrification.
Compost Maturity Assessment Use ammonia levels as an indicator of compost stabilization and readiness for soil application.
Soil Fertility Evaluation Measure ammonium content in soil extracts to monitor fertilizer effectiveness and nitrogen retention.
Environmental Stewardship Link excess ammonia release to nutrient runoff, eutrophication, and the importance of balanced nitrogen management.
Experimental Design Skills Collect and analyze leachate or soil-water extracts, control variables such as aeration and C:N ratio, and interpret ammonia test results over time.
Practical Laboratory & Field Techniques Apply simple dip-strip colorimetric testing as a rapid, reagent-free method for both classroom and field investigations.
Cross-Disciplinary Relevance Integrate chemistry, microbiology, and agronomy concepts to explore the link between nutrient chemistry and sustainable soil management.

Best Practices

  • Collect leachate or soil-water extract after rain or irrigation.
  • Dip strip for 2 seconds, compare after 60 seconds for best accuracy.
  • Test multiple compost zones (core, surface, edges) for consistency.
  • Use periodic testing (e.g., weekly) to track curing progress.
  • Record values alongside temperature and moisture data for interpretation.
