 were conducted. Picture taken May 27, 1960. 



To reduce the acidity and to correct for nutrient deficiencies, 

 lime and fertilizer were applied on the hasis of soil test re- 

 sults. Four plots each, of Narragansett alfalfa ( 14 pounds per 

 acre) and Peiniscott red clover (eight pounds per acre), were 

 seeded on July 28, 1958, and August 1, 1959. An 11x7 grain 

 drill fitted with hand seeding tul)es was used to place the seed 

 above the ])atid of 8-16-16 fertilizer which was applied at the 

 rate of 200 i)ounds per acre. In the spring, and after the first 

 crop was removed, 150 pounds per acre of muriate of potash 

 (60% K.O) was applied. (Figure 1). 



Spring growth produced hy the plants which became estab- 

 lished the preceding summer and fall was harvested on June, 

 1959, and June, 1960. A National sickle bar type mower was 

 used to cut the herbage. The cut herbage was removed by 

 mamial labor. The jdants were allowed to recover to a height 

 of four inches before the basic tractor traffic treatments were 

 applied. 



Eight basic treatments were applied, using a tractor with new 

 tires and a tractor with old, smooth tires. Four different draw-
