[Jan. 



In addition to the regular application of fertilizers, nitrate 

 of soda at the rate of 150 pounds per acre was added two 

 different years to note its effect on both the hay and rowen 

 crops. The increase in the rowen crop due to this treatment 

 was approximately 600 pounds per acre. 



That part of plot 3 lying east of the ditch was plowed in 

 1900, and in 1901 and 1902 it was planted with a cultivated 

 crop. After the removal of the hay crop in 1902, that portion 

 of plot 3 west of the ditch and that portion of plots 1 and 2 

 east of the ditch were plowed. After harrowing several times, 

 all plowed portions were reseeded. At this time plots 1 and 2 

 east of the ditch were subdivided into a north and a south 

 half, and two different mixtures of grass seed sown. On the 

 north half of each plot was sown a mixture known as the fescue 

 mixture, and made up as follows: — 



Timothy, . 

 Red top. 

 Red clover, 

 Alsike clover, 

 Kentucky blue grass, 

 Meadow fescue, . 

 Tall fescue. 



Pounds 

 per Acre.

On the south half of each was sown the timothy mixture, 

 made up as follows: — 



Pounds 

 per Acre. 



Timothy, ........... 18 



Red top, ........... 8 



Red clover, .......... 5 



Alsike clover, .......... 4 



These two mixtures are compared in Table V. 



Plot 3 was reseeded with the timothy mixture. 



A few variations in the fertilizer schedule are noted. In 

 1912 the application of ashes was discontinued, and a mixture 

 of basic slag and muriate of potash substituted. In 1916, 1917 

 and 1918 no potash was applied, and in 1918 the slag was 

 omitted. 



The present system of applying fertilizers in rotation has 

 been in practice twenty-six years. Some portion of each plot
