AGRICULTURAL EXPERIMENT STATION. 85 



The cost of the increase produced by the stable manure is 

 reckoned on a basis of one dollar per ton for the manure. 



The crop of peas on these plots would probably have been 

 much larger had it not been for the severe cold rains in the early 

 part of the season, which proved damaging to most crops during 

 the year 1890. 



Table C shows the method of manuring and the crop produced 

 in studying the question of partial and complete fertilization, i. e., 

 in studying the question whether in all cases it will be more prof- 

 itable to apply nitrogen, phosphoric acid and potash or to omit 

 one or two of these substances. 



This question is one into which every farmer in the State who 

 uses commercial fertilizer should inquire. The standard brands of 

 commercial fertilizers contain all three of the above named sub- 

 stances, and it may happen that only one of them is of use to 

 him In such a case the cost of the crop has been unnecessarily 

 increased by what he has paid for the fertilizing elements that 

 have not materially added to the yield of his land.
