A Micro-Digestion Procedure for the Determination of Aminoid Nitrogen in Plant Material1

  1. Hasan K. Qashu2

Abstract

Abstract

Plant material from two brush species, Ceanothus crassifolius and Adenostoma fasciculatum, was analyzed for aminoid N content using three different digestion procedures. A micro-digestion procedure in a sealed tube gave higher organic nitrogen recovery than two standard Kjeldahl digestion methods. Partial recovery of nitrate N was found when standard digestion procedures were used, but no nitrate N recovery was apparent from the sealed tube method.
