nishing the Nitrogen needed for a relatively large crop, 

 or more than double that on the upland. This is a very 

 clear illustration of the importance of the use of Nitrogen 

 with minerals, if full crops are to be harvested. The 

 application of Nitrate of Soda on the upland proved 

 much more efficient than on the lowland, not only in 

 supplying Nitrogen in immediately available forms, but 

 in energizing the plants to obtain more from the soil, 

 showing a gain in yield of 162 per cent., while on the low- 

 land the gain was but 24.7 per cent.; the soil itself being 

 able in this case to supply a larger proportion of the 

 Nitrogen required to produce a crop as large as the 

 climatic and seasonal conditions would permit. The 

 main point, however, is not how large a yield may be 

 obtained, but the profits that may be derived. The 

 following table shows the financial results of the two 

 experiments from two standpoints: (1) whether it is 

 profitable to grow hay under the conditions, as outlined 

 here; and (2) whether the use of Nitrate will pay.

 Cost of Crops. 



The first point of importance shown by this detailed 

 statement is that notwithstanding the expense involved, 

 there is a profit in hay growing; that it pays to expend 

 money for the good preparation of soil, for good seed and 

 for fertilizers in fact, if the entire cost had been 

 charged to the first crop, there would have been a profit 

 of $5.23 per acre where Nitrate was used on the upland. 

 Second, that it pays to use Nitrate; and third, that the
