■ 



From the results given in table F it would seem that for peas, 

 on the land on which this experiment was carried out, the 

 smallest quantity of fertilizers applied produced the best results 

 financially ; and that in no case was the increased yield produced 

 by the fertilizers sufficient to pay for the cost of the fertilizers. 



Systems of Manuring. 



The object <jf this experiment is to compare a system of 

 manuring with stable manure and systems of manuring with com- 

 mercial fertilizers, and of cropping without manuring. 



In 1888, a ten acre field of grass land located south of the col- 

 lege farm stables was carefully surveyed and divided into four 

 plots extending nearly east and west, each plot being 177 5-10 

 feet wide by 613 52-100 feet long, and containing two and one- 

 half acres. This land is a clay loam and excellent grass land. 



For two years no fertilizers were applied to any of the plots, 

 the grass being cut and weighed carefully to determine the rela- 

 tive conditiion of the plots as to fertility. The plots are num- 

 bered 1, 2, 3 and 4, commencing with the plot on the north side. 

 Their yield of hay for the two years is shown in the following- 

 tables :
