Farm Mechanization

Today helps 2% of America’s workforce meet the food and fiber needs of our nation

Farm mechanization has changed agriculture from 90% to about 2% of the U. S. population being farmers or workers evolved over a 200-year period. Farm machinery has help make this possible

Green Revolution

In the 1960s, countries became self-sufficient in food production by utilizing improved varieties of seeds and farming practices

Eli Whitney

Invented the cotton gin to remove the seed from cotton fiber in 1793

Develop barb wire, with sharp points to discourage livestock from touching fences

Edmund Quincy

Invented the mechanical cotton picker in 1850

Anna Baldwin

Invented the milking machine to replace hand milking of dairy cows in 1878

Agriscience

Is an applied science and it will play a major role in advancing agricultural productivity in undeveloped countries around the world today

U. S. Workforce

2 % of U. S. workforce is found on the farm in the United States today

Farming

The average farmer produced enough food and fiber for 128 people in 1997

Corn

Was the number one grain crop export from the United States from 1992 to 1997 and stills holds true today

The number of farms in the U.S. decreased doing the period of 1985 to 2007 and this trend still exist today

Agriscience employment

The percentage of jobs in agriscience in the United States today is 20%

Agriscience Areas include: Production, Processing, products and distribution

Broilers

Are meat type chickens that United States consumers (citizens) consumed in the largest amount in 1997 and still hold true today35

Poultry

Was the number one meat export as far as tonnage shipped from the U.S. during the mid 1990’s

Pork

was the number one livestock export from the United States from 1992 to 1997 to other countries

Soybeans

Are the world’s most important source of vegetable oil, it provides the basic materials for hundreds of products

Corn

Ranks in the top five U.S. grain exports year after year

Hogs, Broilers, Tobacco

Are the top three agricultural commodities in cash receipts for NC during the late 1990’s (1997-1998) and still holds true today

Farm Size

The average farm size has increased by less than 50 acres from the period of 1985 to 1995

At the present it is projected that the average size of farms in the U.S. will significantly increase while the number of farms will decrease
