Extract

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.
