produce power, heat, or meehanieal energy by 
eonverting resourees either to eleetrieity or to motor 
power. 
Biodiesel, Data are for produetion of non-petroleum 
based diesel fuel made from vegetable oil or animal 
fats. Biodiesel ean be used alone or blended with 
eonventional petroleum-based diesel fuel 
Ethanol A fuel produeed by eonverting erops sueh 
as eorn and sugareane, biomass erops, or wood. This 
fuel is generally blended with gasoline. Produetion 
of ethanol for fuel requires a permit from the Bureau 
of Alcohol, Tobacco, and Firearms (ATF). Only 
ethanol produetion for fuel was reported. 
Geoexchange system. A system that uses 
temperatures from the earth to reduee the operational 
eosts of heating and eooling. 
Methane digesters. It is a deviee whieh eaptures 
biogas resulting from the deeomposition of manure, 
proeessing by-produets, and other materials. 
Harvested biogas is used as a substitute for natural 
gas to power engines whieh generate eleetrieity. It is 
fed into the natural gas pipeline or flared. Methane 
digesters were reported only if in produetion and 
used in 2012. 
Small hydro system. A water driven system, whieh 
produees eleetrieity, by the gravitational foree of 
falling or flowing water. It exeludes water driven 
systems that only provide meehanieal power, sueh as 
turning a grinding stone for a flour mill. 
Solar panel. A flat panel designed to eapture the 
sun’s energy. Include photo voltaie systems, whieh 
eonvert light from the sun into eleetrieity, and 
thermal systems that passively generate eleetrieity. 
Wind turbines. A deviee whieh eonverts wind power 
into eleetrieity. Inelude wind generators, wind power 
units, wind energy eonverters and aero generators. 
Exelude windmills, whieh do not produee eleetrieity. 
Rental of farmland. See Total ineome from farm- 
related sourees, gross before taxes and expenses; 
Gross eash rent or share payments. 
Sales, total. See Market value of agrieultural 
produets sold.

Sheep and lambs inventory. Data for Western 
States (AK, AZ, CA, CO, HI, ID, MN, MT, NV, 
ND, OR, SD, UT, WA, WY) are for sheep and lambs 
of all ages owned regardless of loeation. Data for all 
other States are for sheep and lambs of all ages on 
the operation regardless of ownership. Sheep and 
lambs were eolleeted in their own seetion to elarify 
to respondents when to report “owned” sheep and 
lambs versus any sheep and lambs on the operation. 
Short-rotation woody crops. Data are for short- 
rotation woody erops that grow from seed to a 
mature tree in 10 years or less. These are trees for 
use by the paper or pulp industry or as engineered 
wood. This does not inelude lumber. Aeres in 
produetion were ineluded in Cropland harvested in 
the “Land” section of the report form. 
Size of farm. See Farms by size. 
Small hydro system. See Renewable energy 
produeing systems. 
Solar panel. See Renewable energy produeing 
systems. 
Spanish, Hispanic, or Latino origin. Operators of 
Spanish, Hispanie, or Latino origin are found in all 
of the raeial groups listed in the eensus and were 
tabulated aeeording to the raee reported, as well as 
on tables pertaining only to this group. 
Sport or game fish. Data are for sport or game fish 
raised on farms to be used primarily for sport. 
Examples inelude bluegill, erappie, largemouth bass, 
smallmouth bass, sunfish, muskie, northern pike, and 
walleye. 
Squash, all. All squash is a summation of summer 
squash and winter squash. Total aeres, aeres for fresh 
market, and aeres for proeessing were eolleeted by 
eategory. 
Squash, summer. See Squash, all. 
Squash, winter. See Squash, all. 
Sweet potatoes. Sweet potato aeres are ineluded in 
the vegetable aeres. Data are for total aeres 
harvested, aeres harvested for fresh market, and 
aeres harvested for proeessing. Produetion was not
