The figures in this table show how many pounds of 

 Nitrogen are withdrawn from two and one-half acres of 

 ground by an average harvest. The table shows clearly 

 that the principal quantity of Nitrogen is always in that 

 portion of the crop that is sold, only a small quantity of 

 Nitrogen being found in the straw and leaves, the portion 

 that is retained for use upon the land; consequently, unless 

 a sufficient quantity of nitrogenous fertilizers be applied, the 

 soil will very soon suffer from impoverishment of Nitrogen. 



POINTS FOR CONSIDERATION AS TO 

 PRICES OF FARM PRODUCTS 

 ' AND NITRATE PRICES. 



** T~^ROM the farmer's point of view, a reduction in cot- 

 r1 ton and produce prices is to be deplored, but the 

 point to be considered is whether abstention from 

 the use of Nitrate is a wise way of meeting the situation. 

 The utility of a fertilizer obviously depends upon its pro- 

 ductivity, and as its productivity is not affected by its price, 

 an increase in the latter justifies abandonment of the fer- 

 tilizer only when its productivity ceases to be profitable. 

 The profit to be reasonably expected from the use of fer- 

 tilizer, although somewhat less than when it was cheaper, 

 is not so materially mterfered with by any rise in price of 

 Nitrate as to economically justify any substantial reduction 

 in its consumption."
