On wheat, rye, and other grasses than clover, I have never 
succeeded by direct applications of piaister. Barley and oats 
rolled in plaister have been much benefited. But after clover 
plaistered had occupied the field for its usual time, wheat, 
rye, or any culmiierous crop, have highly profited by the 
amelioration of the soil.
