FURROWING. 



Furrowing, or " creasing," is a practice of making small ditches for 

 distributing water for irrigation. The cultivator and the shovel 

 plow are the implements most commonly used for this operation. 

 In clean cultivation furrows are made just prior to the time of irriga- 

 tion. All orchardists furrowed once; 91 per cent, twice; 63 per 

 cent, three times; 31| per cent, four times; and 3| per cent, five 

 times. Most alfalfa orchardists furrowed but once, just after the 

 spring cultivation. A few of the alfalfa orchardists made a practice 

 of cleaning out the furrows following the harvesting of alfalfa. 



Usually a 6-foot cultivator with three shovels attached, one at either 

 end and one in the middle, is used for making furrows. Four to six 

 furrows, varying in depth from 4 to 6 inches, and approximately 3 feet 

 apart, are usually made between tree rows. 



A crew of one man and two horses with the 6-foot cultivator, 

 making the usual number of furrows — six between rows — covered 8.3 

 acres per day, at a labor cost of 66.3 cents per acre. A crew of one 

 man and one horse with the shovel plow, making the usual number 

 of furrows — five between rows — covered 5.15 acres per day, at a 

 labor cost of 77.6 cents per acre. (See Table X.)
