Note on the vitamin B1 potency of wheat as influenced by soil treatment

Abstract

Specimens of wholemeal wheat flour from plots given various soil treatment were examined for vitamin B1 potency by the heart-rate method. The differences detected were not of a striking order, the relative values being as follows: treated with ammonium sulphate= 120; ammonium sulphate plus “complete mineral manure” = 120; dung = 100; no treatment= 100; complete mineral manure= 80. The lack of any striking variation was also confirmed by growth tests on the “sharps” prepared from the several grains.
