History of Agriculture
Transcript of History of Agriculture
Hand and horse/oxen power , wooden plows, sowing by hand, cultivating by hoe, hay by sickle and threshing with flail. These inventions made farming easier than doing it all by hand.
Cradle and Scythe introduced invention of Cotton Gin (1793)
Thomas Jefferson's plow with moldboard of least resistance tested (1794) In 1797,
Charles Newbold patents the first cast iron plow.
The Cotton Gin made it easier to separate cotton fibers from the seeds.
The first cast iron plow allowed farmers to own plows longer without having to replace it.
In 1819-1825, the U.S food canning industry established.
In 1830, it took about 250-300 labor hours required to produce 100 bushels (5 acres) of wheat.
In 1834, the McCormick reaper was patented and John Lane manufactures plows.
In 1837, John Deere and Leonard Andrus began manufacturing steel plows; the practical threshing machine patented.
The U.S food canning industry helped farmers be able to can their own food from home. It also allowed farmers to store food for long periods of time to either sell or keep for their families.
The threshing machine made threshing hay faster and easier than doing it by hand,
In 1842, In Buffalo, New York the first grain elevator was invented,
In 1843, Sir John Lawes founded the commercial fertilizer industry by developing a process for making super phosphate.
In 1850, it took 75-90 labor hours required to produce 100 bushels (2 1/2 hours) of corn with walking plow, harrow and hand planting.
In 1858, Mason jars used for home canning were invented.

First American Agriculture Revolution
Change from hand power to horse power
In 1874, Glidden barbed wire was patented
In 1890, it took 40-50 labor hours to produce 100 bushels (5 acres) of wheat and 35-40 labor hours to produce 100 bushels (2.5 acres) of corn.
In 1892, the first gasoline tractor was built by John Froelich.
15-20 hours of labor to produce corn (2 1/2 acres)
15-20 hours of labor to produce wheat (5 acres)
Barbed wire made it easier to keep animals in a secured area.
The first gasoline tractor made it faster to farm

In 1940, the average farmer could feed 10 people.
In 1940-1970, technology increased from horses to tractor, making the 2nd revolution.
In 1950, the average farmer could feed 15 people.
In 1955, It took 6 1/2 labor hours to produce 100(4 acres) of wheat with a tractor.
In 1960, the average farmer could feed 26 people.
In 1965, it took 5 labor hours to produce 100 bushels (3 acres) of wheat.
In 1970, the average farmer could feed 50 people.
In 1975, it took 2-3 labor hours to produce 100 pounds (1/5 acres) of lint cotton with tractor
In 1975, it took 3-4 labor hours to produce 100 bushels (3 acres) of wheat with tractor
In 1975, it took 3- 3 1/2 labor hours for corn
In 1990, one farmer could feed 100 people.
Livestock waste became a huge problem
In 1997, the first weed and insect—resistant biotech crops-soybeans and cotton are available commercially
The average farmer is now able to feed 50 more people
Now, weeds and insects can not ruin crops
Now, there are GPS tractors that drive themselves
Technology in Agriculture has came a long way.
