THE MANGUM TERRACE. 



CARE OF THE TERRACE. 



On breaking land which has been terraced in this manner, the ter- 

 race can be entirely disregarded in fields of ordinary slope. On such 

 fields, where the terrace is plowed across in breaking, care must be 

 taken to fill up all dead furrows which may cut the terrace bank. 

 This bank should also be made the center of a backfurrow strip of 

 plowing before a crop is planted. 



On extremely steep lands the plowing is done in contours, and the 

 area included from the crest of one terrace to the crest of the next 

 is plowed as one body. 



Fuj. 9. — The Mangum terrace on steep pasture land. When covered with sod this terrace 

 will last indefinitely with little or no attention. 



SUMMARY, 



The Mangum terrace is a broad bank of earth contouring the field 

 at a grade of approximately 1^ inches to 14 feet. It can be con- 

 structed in several ways. Under ordinary farm conditions the most 

 practical way is by backfurrowing along the grade line. 



This system of terracing is adapted to all types of soil and is espe- 

 cially applicable on moderately rolling lands. On slightly to medium 

 rolling lands the rows can be run on the line of greatest level of the 

 field, cutting across the terrace bank. Extensive cultivation machin- 

 ery can be used with perfect satisfaction where this system of ter- 

 racing is practiced. By its adoption considerable labor will be saved, 

 even though 1-horse implements only be used.
