FIG. I. A HEAVY STAND OF SOAPWEED (YUCCA ELATA) AS IT OFTEN OCCURS 

 ON SANDY SOIL ASSOCIATED WITH BLACK GRAMA GRASS (BOUTELOUA 

 ERIOPODA). 



Plants under 36 inches in height and occasional tall seed plants should be left when such areas 

 are cut over. The young plants and a few older ones will serve as protection against 

 destructive wind erosion and as protection for stock, besides insuring a second crop for cut- 

 ting in perhaps 5 years. 



FIG. 2. SOAPWEED SPROUT THE SECOND YEAR AFTER CUTTING OF THE OLD 



PLANT. 



Indications are that it will require about 10 years for such young plants to reach average size 

 for profitable second cutting.
