A semimicro modification of the Olsen method was developed to include nitratenitrogen in the total soil nitrogen determination by the standard semimicro-Kjeldahl method. The modified method was found to include nitrate-nitrogen effectively from standard nitrate solutions and soils. It was significan
A fast, simple, and very sensitive method for the simultaneous determination of nitrate and nitrite was developed by coupling the high ultraviolet absorbance of these compounds with their separation from one another and from components of media and cell extracts by highpressure anion-exchange liquid
