Bulletin 261. 



September 15, 1903, the north half of each plat was treated with slaked 

 lime at the rate of 1000 pounds per acre, fifty pounds of caustic lime being 

 placed in a pile on each plat and covered with earth until slaked. This 

 was then spread uniformly. All fertilizers were applied by hand. 



The plan was to seed to wheat and timothy in the fall of 1903, so the 

 first application of fertilizers and stable manure that the plats received, 

 was made September 16, 1903. Early fall rains prevented the seeding of 

 wheat, as planned, and in the spring of 1904, on April 15, oats were sown 

 at the rate of nine pecks per acre together with timothy at the rate of 

 fifteen pounds per acre, without the application of any further fertilizers. 

 The second application of fertilizers was made April 5, 1905 ; the third 

 application, April 17, 1906; and the fourth, May i, 1907. Stable manure 

 was not added every year as were the fertilizers, the second application 

 being made October 2, 1906. 



The table following gives the amounts of the fertilizing materials 

 added, together with the yield of hay from the various plats for the 

 years, 1905, 1906, 1907. The treatment of each plat since the beginning 

 of this experiment has been as this table designates, with the following 

 exceptions: In 1904 and 1905, Plat 727 received at each application 

 160 pounds nitrate soda instead of 320 pounds as in 1906 and 1907; 

 Plat 728 received, in 1904 and 1905, 160 pounds of "niterlime" at each 

 application instead of 640 pounds nitrate of soda, as in 1906 and 1907. 

 The other fertiHzing constituents remained the same.
