' 2008 data do not include non-horticultural field crops and pasture acreage on horticulture operations. 
^ Subirrigation data were collected as a separate item in 2008 but were collected under “Other gravity systems” for 201 3. For the 2008 data, subirrigation data were added to "other gravity systems" for 
comparability.
