capacity for the remaining wells, if any. Artesian 
wells are not ineluded as wells pumped. The average 
pumping eapaeity was ealeulated using these 
reported data. 
Barriers to making improvements to reduce 
energy use or conserve water. This item shows the 
barriers to implementing improvements that might 
reduee energy and/or eonserve water. Respondents 
were asked to report for the period eovering 2009 to 
2013. The information was tabulated as reported. No 
imputation was made for a blank response. 
Cropland harvested. This eategory ineludes land 
from whieh crops were harvested and hay was eut, 
land used to grow short-rotation woody erops, and 
land in orchards, citrus groves, Christmas trees, 
vineyards, nurseries, and greenhouses. Land from 
whieh two or more erops were harvested was 
eounted only onee. Land in tapped maple trees was 
included in woodland. 
Cropland not harvested or grazed. This category 
ineludes aereage whieh eould have been used for 
erops without any additional improvement and 
whieh was not reported as eropland harvested or 
other pasture or grazing land that could have been 
used for erops without additional improvements. 
This category ineludes: 
1 . Land used for cover crops or soil improvement 
but not harvested or grazed. 
2. Land in Federal or State eonservation programs 
that was not hayed or grazed in 2013. 
3. Land oceupied with growing erops for harvest in 
2014 or later years (exeept fruit or nuts in an 
orchard, grove, or vineyard or berries being 
maintained for produetion). Example is aereage 
planted in winter wheat for harvest in 2014 and 
no erop was harvested from these aeres in 2013. 
4. Land in summer fallow in 2013. 
5. Land with erops that failed and no crop was 
harvested on the aereage in 2013. 
Crops unit of measurement. Crop units were 
preprinted on the report forms and respondents were 
instrueted to report erops in these units.

Estimated quantity of water applied. Most water 
used for irrigation is not metered or measured 
aeeurately. The quantity of water data are based on 
the best estimates provided by irrigators. Generally, 
in areas with water shortages, such as southern 
California and Arizona, irrigators are more likely to 
provide aetual quantities of water used than in 
Mountain States where water shortages may be less 
of a problem or preeise measuring methods are not 
readily available. In the Mountain States where 
water from snow-melt is diverted for use in season, 
the amount of water used may be a rough estimate, 
seldom a measured figure. 
Expenditures for irrigation facilities and 
equipment. There are six eategories of 
expenditures. The expenditures purposes include; 
new expansion, water conservation, energy 
eonservation, and seheduled replaeement or 
maintenanee. The expenditures are also grouped by 
primary souree of funding. 
Farms using off-farm water. Respondents were 
asked to report the amount (none, some, or all) of 
off-farm water supplied by the U.S. Bureau of 
Reelamation, other federal agencies, and all other 
suppliers. However, many respondents did not 
answer this question. Instead, the eomputer edit set 
the entry to unknown. The number of farms using 
water from the U.S. Bureau of Reclamation, other 
federal agencies, and all other suppliers may be 
understated. 
Flowing wells. See Artesian wells. 
Gross value of agricultural products sold. See 
Market value of agricultural products sold. 
Horticultural crops. The horticultural data are 
published in the following eategories: 
Christmas trees and short rotation woody crops. 
Ineludes all trees to be eut in 2013 or later years. 
Irrigated live Christmas trees were reported in 
nursery erops.
