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.
