Slow Neutrons

Curves of counting rate versus moisture content are presented, for sand, loam and clay soils, using (i) a 1000 me Ra-Be source surrounded by a small rigid indium cylinder acting as detector of slow neutrons and (ii) two co-axial Cd cylinders protecting the indium detector. Improved accuracy in the region of low moisture contents was obtained with (ii). (Abstract retrieved from CAB Abstracts by CABI’s permission)

1. The colorimetric determination of phosphoric acid in hydrochloric and citric acid extracts of soils by a method involving the evaporation of the extract, ignition and acid extraction of the residuewith either the Denigès and Fiske-Subbarow methods of colour development was satisfactory only with light soils. Clay soils gave low results owing to the presence of larger amounts of iron.2. A method is given in which the organic matter and iron are removed by treatment with sodium permanganate and potassium ferrocyanide. The results are in good agreement with the gravimetric method.
