These tests have been carried on here on the Station Farm 

 for four years, on a series of plots, twenty-four in number. The 

 plan of experiment has been as follows : plots of 1-20 of an 

 acre were laid out according to the plan on page 12. This 

 was done in 1885, each plot was seperated from the ad- 

 joining ones by a vacant space three feet wide. Each plot ex- 

 cept those marked nothing, has received $8.00 worth of fertili- 

 zer yearly per acre for three years, 1885, 1886, 1887, or $24.00 

 in all. The table on page 14 shows the actual amount of each 

 material used on each plot. 



The crops were, corn, oats, and hay ; with the corn the fertili- 

 zer was applied 2-3 broadcast and 1-3 in the hill, and the 

 whole broadcast on the oats. 



The table is computed to yields per acre, and as the second 

 years crop of corn was not recorded, I have assumed that it 

 was the same as the first, that part of the table showing value 

 of crops is on the basis of corn, sixty cents per eighty pounds 

 as husked, soft corn ten cents per bushel of thirty-four pounds. 

 Fodder, $6.00 per ton, Oats fifty cents per bushel, Straw $6.00 

 per ton and hay $10.00 per ton. The column marked "value of 

 crops for four years," adds the first years crop in twice, which 

 is not far from right, this is done to facilitate comparison 

 with the third and fourth acres given later in this bulletin. The 

 columns showing ''composition of fertilizers" gives the per cent 

 of nitrogen, phosphoric acid and potash, in each mixture. In 

 plot twenty-two, sulphate of potash was used the second year 

 and the percentage is figured on the three applications, this is 

 not strictly accurate, for the first crop had no potash at all, and 

 the other crops were greatly benefited by the application as the 

 yield will readily show. Had potash been added the first year, 

 the crop would have been considerably larger. 



At the bottom of the page the average of the plots with no 

 fertilizer is given. 



Plots two, three, eleven, and twelve only received fertilizers 

 the first two years, consequently they cannot be compared with 

 the others except for the first years corn crop. 



Plot twenty-two had two application of bone, one in 1885 

 the other in 1887 and in 1886 an application of sulphate of 

 potash was made.
