1 These plot experiments were carried on under cooperative agreements between the Division of Agri- 
cultural Engineering, Bureau of Public Roads, United States Department of Agriculture and the Utah 
Agricultural Experiment Station on the Greenville Farm, the property of the Utah Agricultural College 
located 2 miles north of Logan, Utah. 
The plots were 29 feet wide by 57 feet long and contained nearly 0.03793 of an acre. The computations as 
regards the quantity of water used were based upon the actual size of each plot. 
Considering the variety of soils to be found on most tracts, the soil of the Greenville farm is uniform in 
texture, consists mainly of sand and silt, is of great depth and is far removed from a water table.
