Product Description
The Hanna nitrate test kit for soil and irrigation water makes it possible to determine the need for nitrogen fertilization. It also obtains the best crop response and avoids over-fertilization. Nitrate is reduced to nitrite in the presence of cadmium. The nitrite thus produced reacts with the reagent to yield an orange compound. The amount of color developed is proportional to the concentration of nitrate present in the aqueous sample. The Hanna nitrate-nitrogen test can be performed the whole year round, but testing is particularly recommended during spring and late spring, when rainfall and temperature related bursts of microbiological activity often have great influence on the availability of nitrate-nitrogen. Test kit comes with 200 packets nitrogen reagent, checker disc, glass vials with caps (2), 10 g calcium sulfate, demineralizer bottle with filter cap for 12L, soil sieve, 50ml plastic test tube with screw cap, large funnel, 100 paper filter discs, brush, 50ml calibrated vessels (2), 2 g sample cup, 3ml plastic pipette and spoons (2). Checker disc method. Range: water 0-50 milligram per liter, soil 0-60 milligram per liter. Smallest increment: water 1 milligram per liter, soil 2 milligram per liter. Cadmium reduction chemical method. Number of tests 200. Weight: 1026 grams. see details
