TABLE No. 14. Preference of growers as to depth to plow alfalfa sod. 



Here are a few reports: 



. Cherokee county: "The deeper you plow the smaller the roots and the 

 easier cut." 



Russell county: "You can't break shallow and keep the plow in and do 

 a good job." 



Jefferson county: "Shallow if you want to kill the plants. Then fol- 

 low by deep tillage." 



Rice county: "Deep if stand is thin; if not, plow shallower, disk well, 

 and harrow." 



Trego county: "Turn it shallow in summer or fall and plow deep the 

 following spring." 



Osage county: "We plow shallow, just below the crowns, to make a 

 seed bed. The alfalfa has done the rest far better than we could with 

 all the teams and tools on the place."
