DETAILED DESCRIPTION OF EXPERIMENTS. 



As previously stated, all of the seed used in these experiments was 

 produced in the crop year 1903 and all of the experimental areas 

 under discussion were sown in the spring of 1904. The observations 

 made in each State w ill be discussed separately. 



THE EXPERIMENT IN NEBRASKA. 



LOCATION. 



The work in Nebraska was carried on in cooperation with Mr. John 

 P. Young, on his farm near Oakland, Burt County. This place is 

 situated at about latitude 41° 50' N. and longitude 96° 26' W., in 

 the Elkhorn Valley, near the present western limit of successful clo- 

 ver culture. 



SOIL. 



With the exception of a streak of limited extent, where the sub- 

 soil crops out, the soil of the clover field is a silted sandy loam of 

 dark gray color and of such structure that w4th insufficient moisture 

 it becomes aggregated into a hard, almost impenetrable mass. After 

 rains it becomes very plastic and tenacious, very much resembling 

 clay in tliis respect. On account of tliis character a large part of 

 the soil of the Elkhorn Valley has become known under the name 

 "clayland." This soil is further distinguished by a comparatively 

 large percentage of well-distributed calcareous matter. This is a 

 factor of great importance to successful clover culture, and no doubt 

 helps to account for some of the heavy yields obtained in tliis soil.
