SUMMARY

This discussion centers on the feasibility of creating homemade nitrate test strips using common household items. It highlights the challenges associated with adapting existing chemistry for nitrate determination to a paper strip format. The conversation suggests that while DIY nitrate test strips are theoretically possible, they require specific raw materials and calibration with known standards, making them potentially impractical for casual users. Instead, the recommendation is to utilize commercially available aquarium water test strips, which include tests for nitrates, ammonia, and other parameters, albeit with less precision.

PREREQUISITES
  • Understanding of nitrate chemistry and its measurement techniques.
  • Familiarity with calibration methods for chemical testing.
  • Knowledge of materials used in DIY chemistry projects.
  • Experience with colorimetric analysis and interpretation of results.
NEXT STEPS
  • Research the composition and functioning of commercial nitrate test strips.
  • Learn about colorimetric analysis techniques for measuring nitrate levels.
  • Investigate calibration methods for DIY chemical testing kits.
  • Explore alternative methods for measuring nitrogen content in soils, such as using spectrophotometry.
USEFUL FOR

Gardeners, DIY enthusiasts, and educators interested in soil testing and chemistry, as well as anyone looking to understand the practical applications of nitrate measurement in various contexts.

Hi, I was wondering how I might make my own nitrate test strips. I am not really sure how/if they are any different from normal red/blue pH strips.

I am looking for a way to compare nitrogen content in different soils. I know they make cheap kits, but I was hoping there was a way to do it with what I have in stock already.

If such strips are sold, it can be doable. If they are not on the market, that typically means chemistry used for nitrates determination is hard to adapt to a paper strip.
 
I don't know about DIY but any pet store will have aquarium water test strips or liquid test kits. They typically contain tests for ammonia, nitrates and nitrites (also pH and hardness). They are not very precise as you have to eyeball the color compared to a standard card or some such thing that comes with the kit. I think that is your best bet. If you make a DIY kit you will need to get all raw materials and put them together, then calibrate it in some way with known standards. That can be a time and money sink which may not be worth if for you if you're project is about measuring nitrogen instead of building nitrogen test kits.
