ably expected and a fair start made in a systematic 

 rotation. 



While the green crop and farmyard manure 

 which has been prepared and worked into the surface 

 soil will provide the necessary amount of vegetable 

 matter and nitrogen for the wheat crop, provision 

 should be made for increasing the fertility of the soil 

 by seeding the fall wheat with clover to provide a 

 further supply of vegetable matter and nitrogen 

 (two essential elements of fertility). Three pounds 

 of timothv seed mav be sown with the fall wheat.

Sow the timothy seed in front of the grain spouts 

 so that it will be scattered between the rows of 

 grain. If sown behind the grain spouts the timothy 

 seed will fall in the creases with the grain and is 

 liable to be choked out. 



Clovers require to be sown in the early spring 

 with a grass seed sower (see 111. 52) at the rate of 

 about eight pounds of red clover and three pounds 

 of alsike clover seed per acre. 



After the clovers are sown and the land is dry 

 it is an advantage to harrow across the rows of wheat
