Soil automated techniques have been developed for the analysis of various extracts for soil phosphate, using Technicon Auto-Analyzer II. Assessment were made into the design of suitable Technicon, manifold to overcome specific problems relating to the use of various soil extracting solutions. On the basis of these assessments (paper I and II), and in addition consideration of the effect of the aerosol 22 concentration on the smoothness of flow, shape and smoothness of peak, a table of conditions for different extractants was drawn up. The nature of the wash chamber solution and the amount of wetting agent were the main factors controlling the quality of peaks. Technicon manifold for different levels of phosphorus were also investigated.
