The first point requiring particular notice is the 

 variation in the proportions of oats and peas on the 

 different plots. It is quite evident that the peas must 

 have drawn their Nitrogenous food from the soil rather 

 than from the air. While this difference in proportion 

 of oats and peas would make a difference in the quality 

 of the hay for feeding, it probably would not make any 

 difference in the price that would be received for it as 

 hay. The oat and pea crop is not generally grown for 

 market, but for use upon the farm and is an especially 

 valuable crop upon farms devoted largely to the growing 

 of hay for market, because furnishing food for stock, 

 and thus enabling the disposal of the high-priced hay, 

 though really less useful as feed. 



The second point to be observed is that the Nitrate 

 increased the yield of crop in every instance above that 

 obtained on the check plots, and while the yields upon 

 the check plots are lower than upon any of the Nitrated 

 plots, that upon plot 6 is much higher than upon plot 1, 

 and this can be explained on the ground that, owing to 

 the larger application upon plots Nos. 5 and 7, there 

 may have been some feeding upon the adjoining crops, 

 as the records show that up until the week of July 24, no 

 differences were discernible in the height and the appear- 

 ance of the oats upon the two plots, but after that date 

 the crop on plot 6 began to improve. The average, 

 however, of the two plots is so much lower than upon 

 any one of the others as to make the comparison a safe 

 one for study. 



The following table has been prepared to show the 

 increase in yields upon the various plots, as compared 

 with the average of the two check plots :
