sand fields in the spring. Fall cover-crops should be given 

 much attention. 



Other Points on Management. In clearing sand lands, grass, 

 leaves, etc., should never be burned, but plowed under when- 

 ever possible. 



Plowing. First plowing should never be more than four and 

 one-half to five inches deep, and subsequent plowing not deeper 

 than six inches. Spring plowed land should be made firm by har- 

 rowing and rolling. A weeder is a good implement for sandy 

 soils (Fig. 210).

Drill Best for Sands. It has been clearly shown that the drill 

 grain-sower is the best to use on sands (p. 314). It is best to drill 

 in the clover seed also, not with the grain, but separately and in 

 opposite directions to the grain drill-rows (p. 79). 



Peat for Sand Improvement. Many sand sections include 

 numerous peat marshes. When convenient, the peat may be 

 applied to the sands to increase the organic matter and the nitrogen 

 supply. In some countries this is a common practice. Twenty- 

 five loads may be applied to the acre. It is quite necessary to 

 supplement the peat with phosphate and potash fertilizers. 



Crops for Sands. Sands respond readily to proper treatment. 

 Moreover, they warm up quickly and are easily worked. When
