When Results Matter

Accurate nitrate and phosphate results, on-site or in your own workspace. NECi enzymatic test kits cover soil, water, crop foliage, and animal forage. Non-toxic and trusted since 1993. Learn more about our ag kits.

Nitrate kits need no instrument. Results are read by eye against the color chart. The GaiaXus handheld photometer is optional, for digital readings and GPS-tagged data.

Phosphate kits require a spectrophotometer that reads at 360 nm and accepts standard square cuvettes.
