SECTION 8 
METHOD OF WATER DISTRIBUTION IN FIELDS IN THE OPEN ON THIS OPERATION IN 2013 
Report acres irrigated by each type of FIELD distribution or delivery system listed below. If the same land was irrigated 
by more than one method of distribution, report acres irrigated by each method used. Report information for the field 
distribution system, NOT for the delivery system used to convey water from the source to the field, if different. Include 
acres of horticultural crops grown in the open. Exclude crops grown under protection; glass, rigid plastic, plastic film, 
including "tunnel" protection. (Methods for crops grown under protection will be reported in Section 13.)
