Abstract

Dion and Mann1 have shown that, as extractants for manganese from soil, neutral sodium and potassium pyrophosphates are much more effective than the corresponding orthophosphates. Since then, Heintze and Mann2 have shown that various organic hydroxy-acids are almost as effective as pyrophosphate, and much more effective than the corresponding unsubstituted acids, as soil-manganese extractants.
