Nitrogen Basics – The Nitrogen Cycle

Nitrification is the process by which microorganisms convert ammonium to nitrate to obtain energy. Nitrate is the most plant available form of N, but is also highly susceptible to leaching losses. Nitrification is most rapid when soil is warm (67-86°F), moist and well-aerated, but is virtually halted below 41°F and above 122°F. R-NH 2 Æ NH

41: Nitrate Reduction - Biology LibreTexts

Aug 01, 2021· NITRATE TEST . This test determines the production of an enzyme called nitrate reductase, resulting in the reduction of nitrate (NO 3): the test is also called the nitrate reduction test.With this enzyme, nitrate is reduced to nitrite (NO 2).It then forms nitrous acid that reacts with the first reagent sulfanilic acid, and that reacts with the other reagent naphthylamine to form a red color.
