Objective OneObjective One

Define Agriculture and The Agriculture Industry

What is Agriculture?What is Agriculture?

Agriculture is the science of growing crops and raising animals to meet the needs of humans

What is the What is the Ag IndustryAg Industry??

Involves all activities involved with providing people with food, clothing, and shelter

Includes farm operations, and Nonfarm operations Largest industry in America

What are Farming What are Farming Operations?Operations?

Uses land and other resources to grow crops and raise animals

Includes conventional farming, suburban farming, aquaculture, and forestry

Conventional Conventional FarmingFarming

Larger acreage of land growing typical grains of corn, soybeans, wheat, and other similar crops

Producing larger numbers of animals like swine, beef and dairy cattle, and sheep

Suburban FarmingSuburban Farming

Normally involves smaller areas of land

Normally found in residential or business locations

Typical products would include vegetable crops and small animals

AquacultureAquaculture

“Farming the Water” Involves raising fish or similar

aquatic animals Also includes producing aquatic

plants like water cress or water chestnuts

ForestryForestry

Involves the production and use of trees

What are Nonfarm What are Nonfarm Operations?Operations?

Normally referred to as Agribusiness

Agribusiness is nonfarm work in areas such as ag supplies, services, marketing, and product processing

Agriculture Also Makes the Agriculture Also Makes the Lives of People BetterLives of People Better

Ornamental Horticulture produces flowers and plants for their beauty

Natural Resources involve working with things found in nature like soil, water, and air

Objective TwoObjective Two

Identify Important Historical Developments in

Agriculture

Two Important Groups of Two Important Groups of People That Affected Early People That Affected Early AgricultureAgriculture

Native Americans

Colonists

Native AmericansNative Americans

Includes Indians, Hawaiians, and Eskimos

Hunting and gathering met their food and fiber needs

Indians first began simple farming By 1000 AD, corn is being grown in

large plots

ColonistsColonists

Learned many successful ag practices from Native Americans

Credited with early domestication of animals, which is the taming, confinement, and breeding of animals for human use

Objective ThreeObjective Three

Explain major technological developments in agriculture

What is Technology?What is Technology?

Technology is the application of knowledge to practical use

Uses inventions (new devices, products, or ways of doing work) for easier work and better living
