Lime and Fertilizers. 



Satisfactory yields of sweet clover are very seldom secured on acid 

 soils. Even though the stand may be fair at first the plants will be 

 stunted in growth and but a small amount of hay or pasture secured. 

 When the soil is in this condition it usually requires from one to three 

 tons of ground limestone or from three to six cubic yards of marl per 

 acre to secure good results. The average application of ground lime- 

 stone is approximately two tons per acre.
