The hitherto customary valuation of manurial substances is based on the average trade value of the essential fertilizing elements specified by analysis. The money value of the higher grades of agricultural chemicals and of the higherpriced compound fertilizers depends, in the majority of cases, on the amount and the particular form of two or three essential articles of plant food, ie, phosphoric acid, nitrogen and potash, which they...
