Acid
Soil: A soil with an acid reaction,
a pH less than 7.0.
Acre:
A parcel of land, containing
4,840 square yards or 43,560 square feet.
Agriculture: The utilization of biological
processes on farms to produce food and other
products
useful and necessary to man.
Both a “way of life” and a “means of life” for the people involved
in
this
industry.
Agriculture Extension
Service: Cooperative (Federal, State,
and County) agency doing research
and education for rural and
urban producer and consumer groups, located in each county
with
specialist personnel for each
particular area.
Agronomy:
The science of crop production
and soil management.
Alfalfa:
A valuable leguminous crop for
forage or hay used in livestock.
Animal
Unit: A unit of measurement of
livestock, the equivalent of one mature cow
weighing
1,000 lbs. The measure is used
in making comparisons of feed consumption. Five mature ewes
a
also are considered an animal
unit.
Annual:
A plant that completes its
life cycle from seed to plant, flower, and new seed in 1 year
or
less.
Apiary: Colonies of bees in
hives and other beekeeping equipment for the production of
honey.
Artificial Insemination: The
mechanical injection of male semen into the womb of the female
with
a special syringe-like

male.
This method is used
extensively in dairy husbandry.
Auger: Spiral device on a
shaft used to move grain through a tube.
Avian: Pertaining to poultry
and/or fowl.
Balance Ration: A ration which
furnishes all the necessary nutrients in the proportions
and
amounts needed by the animal
for normal functioning and growth.
Bloating: Abnormal swelling of
the abdomen of livestock, caused by excessive gas
formation
which can result in
death.
Boar: A breeding male hog, any
age.
Breed: A group of animals
descended from common ancestry and possessing certain
inherited
characteristics which
distinguish it from any other group. When matings within the breed
are made,
these characteristics are
transmitted to the offspring in a uniform and predictable
manner.
Breeds of Beef
Cattle:
English Origin: Aberdeen
Angus, Hereford, Shorthorn
European Origin: Charolais,
Chianina, Gelbvieh, Limousin, Maine Anjou,
Simmental
Asian Origin:
Brahma.
United States Developed:
Brangus, Beefmaster, Santa Gertrudis,
Red Angus.
Broadcasting: Random
scattering of seeds over the surface of the ground. If the seed is

sex about 7 weeks of age.
Bushel: A unit of dry measure
(1 cubic foot) for grain, fruit, etc., equivalent to 8 gallons of
liquid.
Weight varies with the
density/bulk of the commodity. Example: Oats weigh 32 lbs.
Per
bu.; barley, 46 lbs. Per bu.;
and corn, 56 lbs,. Per bu.

sexual maturity) animal of the bovine
species.
Cash Crop: Any crop that is
sold off the farm to yield ready cash.
Certified Seed: Seed grown
from pure stock which meets the standards of certifying
agency
(usually a state government
agency). Certification is based on germination, freedom from
weeds
and disease, and trueness to
variety.
Complete Fertilizer: A
fertilizer containing the three macro nutrients (Nitrogen,
Phosphorous, and
Potassium) in sufficient
amounts to sustain plant growth.
Compost: Organic residues, or
a mixture of organic residues and soil which have been
piled,
moistened, and allowed to
undergo biological decomposition. Mineral fertilizers are
sometimes
added.
Confinement: Livestock kept in
“dry-lot” for maximum year-round production. Facilities may
be
partial or complete solid
floored and enclosed/covered.
Controlled Lighting:
Artificial lighting of poultry housing. Increasing or decreasing
the number of
hours of light during the day
will control sexual maturity, fertility, and
molt.
Cooperative: An organization
formed for the purpose of production and marketing of goods
or
products owned collectively by
members who share in the benefits. Most common examples
in
agriculture are canneries and
creameries.
Crop Rotation: More or less
regular recurrent succession of different crops on the same land
for
the purpose of maintaining
good yields.
CWT: Hundredweight or 100
pounds.
Double Crop: Two different
crops grown on the same area in one growing
season.
Drainage: The removal of
excess surface water or excess water from within the soil by means
of
surface or sub-surface
drains.
Drilling: The process of
opening the soil to receive the seed, planting the seed and
covering it in a
single
operation.
Dry Cow: A cow that is not
producing milk, the period before the next calving and
lactation.
Dry Land Farming: The practice
of crop production without irrigation.
Erosion: The wearing away of
the land surface, usually by running water or
wind.
Feed
Lots:
1. Dry Lot Feeding: Feeding
process wherein cattle are confined in a small area and fed
carefully
mixed, high-concentrate feed
to fatten them.
2. Farm Feed Lot: Where cattle
feeding is complementary with other farming
enterprises.
3. Commercial Where cattle are
fed for others on a custom basis. Feed usually
is

hired.
Fertilization: The union of
pollen with an egg to form an embryo.
FFA: Future Farmers of
America-an organization for high school students studying
