September, and the above-mentioned ration should be used 

 as a top-dressing the following spring, as soon as the grass

If all the conditions are favorable from three to five tons 

 of clean barn-cured hay, free from weeds, may reasonably 

 be expected. When grass crops are heavy and run as high

 and enables it to get ahead of all weeds, and the crop then 

 feeds economically and fully on the other manurial con- 

 stituents present in the fertilizer mentioned in the formula 

 and present in the soil. 



When Nitrate costs about $50.00 per ton and clean hay 

 sells $16.00 per ton the financial results are very satisfactory. 

 Nitrate can sometimes be used alone for a season or two and 

 at very great profit, but a full grass ration is better in the long 

 run for both the soil and crop. Generally speaking, 100 

 pounds of Nitrate, if used under proper conditions, will 

 produce an increase of from 1,000 to l,200 pounds of barn-
