SOURCE IN 2013 
1, For each method used to irrigate or water horticultural crops under protection, report water sources by percent of 
source applied. If more than one source was used, report all that apply. For example, if the only source for 
hand-watered crops was ground water, then report 100 percent in column 1. If this operation used gravity irrigation 
and half of the water came from ground water and half came from on-farm surface water, then report 50 percent in 
column 1. row b and 50 percent in column 2, row b.
