Enduring Understandings
Human life depends on agriculture
-People interact with each other and the environment to accomplish goals
- technology changes how people live and work
First farmers in Georgia
Mississippian Indians
Two presidents impacted agriculture in GA
FDR: researched crop rotation (moving crops to reduce loss of nutrients)
-received peanut oil from Carver and believed it helped with polio
-built relationships with people in GA when visiting warm spring and created parts of New Deal to help them
Carter: went from peanut farmer to president!
Agriculture is Georgia's Largest Business
-more than 74 billion dollars per year to GA economy
-1 in every 7 Georgian works in a business related to agriculture
Agriculture related business
-Farm input and machinery: seed, feed, and fertilizer the companies that provide these services
-Food and fiber processing: turn the raw material into products we use
-Food wholesale and retail: selling the food, grocery store chains and their suppliers
-Food service industry: restaurants and institutions
Top 5 Agriculture Commodities (what makes GA the most $) from 2015
Broilers-$4.25 billion
Chicken eggs-$763 million
Cotton and peanuts-$694 million each
Cattle-$530 million
Dairy/milk-$359 million
US ranking of GA Farm Commodities (How we compare to other states in making $ from these products)
#1 peanuts, Rye, broiler production, blueberries, pecans, Spring season onions.
#2 cucumbers, watermelon, pullets, cotton.
#3 peaches, bell peppers, and sweet corn.
*we produce the largest amount of the crop but we don't make the most $ off of it

Categories of water use
Domestic (houses)
Commercial (companies)
Industrial (factories)
Electric Power Production (spinning turbines!)
Livestock animals get thirsty)
Irrigation (plants get thirsty)
Most fresh groundwater is used for
Irrigation: watering crops
Crops that use the most irrigated water from the ACF River Basins
Field nursery
Flood (furrow) Irrigation
Water is brought or pumped into fields and flows along the ground among the crops
-Farmers must make sure the ground is level
surge flooding: releasing water at specific times to reduce run-off
-To stop run-off, farmers.... Capture and reuse water

Pros: cheap, low tech
Cons: evaporation, runoff
Drip Irrigation
Water is sent through plastic pipes (with holes in them) that are laid along rows of crops or buried next to the crop

Pros: less evaporation, runoff
Cons: doesn't move, ore complex
Spray Irrigation
A long tube is fixed to a water source and is through the tube onto crops...like a sprinkler
Pros: covers a large area
Cons: cost, doesn't move, more complex, wind evaporation
Center Pivot Spray Irrigation
Spray irrigation that rolls around the field and uses the center point as the pivot or point of movement
Pros: covers a large area
Cons: cost, more complex, wind evaporation
Low Energy Spray Irrigation
The long tubes point toward the ground to decrease evaporation and the amount of pressure needed. Uses gravity to its advantage.
Pros: covers a large area, decreases evaporation, uses less energy
Cons: cost, more complex
