SOIL MOISTURE 



335 



The right kind of mulch for 

 moisture conservation is 

 granular that is, the dirt 

 should not be pulverized too 

 finely. 



The wrong kind of mulch. The 

 ground is almost dust. Such 

 mulch blows away easily. 



The granular mulch rained up- 

 on and left standing for a 

 number of days. Observe 

 that the ground is cracking 

 and that moisture is escaping 

 through these cracks. The 

 crust can be easily broken. 



Dust mulch rained upon and 

 left standing in the hot sun. 

 Note that the crust has 

 cracked, and that the moist- 

 ure is escaping very rapidly. 

 It is impossible to work up 

 this seed bed properly.
