Abstract

Abstract

Soils research dealing with environmental quality requires the analysis of large numbers of samples to better characterize the problem. An automated technique, using a Tecator digester and Technicon AutoAnalyzer, has proved to be as reliable as the standard micro-Kjeldahl procedure and permits more rapid analysis of the digests (30 per hour). The system is compact and involves fewer steps for analytical error.
