Extract

It was recently suggested by the writer that the neutral salt test for sourness in soils could be adapted for rapid qualitative purposes by using an alcoholic solution of potassium thiocyanate. This reagent becomes coloured in contact with soils deficient in strong bases, because of the presence of iron among the weak bases which are brought into solution from such soils by neutral salts.
