Soil for the onion. 



A sandy loam, with a clay subsoil, will give excellent 

 returns, provided there is an abundance of humus or 

 other nitrogenous matter present. Humus may be 

 supplied by turning under leguminous crops. The roots

 putting the tile drains close together, so as to remove 

 the surplus water quickly. 



The land should be plowed shallow but thoroughly, 

 leaving no particle unturned. All roots or sticks or other 

 debris should be removed before plowing, and again after

 found excellent for fertilizing onions. Whatever kind
