Title: Agriculture

2Commercial Farming
- Definition
- Commercial farmers produce their crops to sell
them in the marketplace - Commercial farming types include mixed crop and
livestock farming, ranching, dairying, and
large-scale grain production
- Plantation farming is a form of commercial
farming - Mainly practiced in less developed countries
3Commercial Farming
- Mixed Crop and Livestock farming
- Definition
- Involves a farm that grows crops and raises
animals - Most crops grown on mixed farms are used to feed
the farms animals - Provides manure fertilizer for sale as well as
goods
- Most of mixed farms income comes from sale of
its animal products - Reduces farmers dependence on seasonal crops
- Devotes nearly all land to crops but 3/4ths of
income comes from sale of animal products - Exists widely throughout Europe and Eastern
Northern America - Usually farms are near large, urban areas
- Most mixed farms practice crop rotation
4Ranching
- Definition
- Commercial grazing, or the raising of animals on
a plot of land on which they graze - Ranching is usually extensive
- Cattle and sheep are most common animals on
ranches
- Practiced in areas where the climate is too dry
to support crops - Semi-arid, arid land
- Western U.S, Argentina, southern Brazil, and
Uruguay - In U.S. part of pop culture
- Also on coast of Latin America and Northern
Mexico - Declining in importance
- Began declining in U.S. in 1880s
- Partly because of low grain prices and because of
U.S. meat quality standards - Many U.S. ranches are being converted into
fattening farms
5Dairying
- Definition
- Growth of milk-based products for the marketplace
- Dairy farms closest to the marketplace usually
produce the most perishable, fluid-milk products - while those father away produce goods such as
cheese and butter
- Most economically productive type of commercial
agriculture - practiced near cities in the northeastern U.S,
southeastern Canada, and northwestern Europe
6Dairying
- Dairy Farms usually very small and capital
intensive - Uses a lot of machinery in the farming process
- Labor-intensive uses more human labor
- The milkshed is the zone around the citys center
in which milk can be produced and shipped to the
marketplace without spoiling
- Growth in transportation technology has increased
area of the milkshed - Improved technology and feeding systems have led
to increases in the amount of milk produced per
cow
7Large-Scale Grain Production
- Definition
- Where the grains are most often grown to be
exported to other places for consumption - Wheat is the dominant grain on large-scale grain
farms - Worlds largest export crop
- Common in Canada, U.S., Argentina, Australia,
France, England, and the Ukraine - U.S. largest grain producer
- Within North America, large-scale grain
production is concentrated within three areas - Winter-wheat belt
- Kansas, Colorado, Oklahoma
- Spring-wheat belt
- Dakotas, Montana, Southern Saskatchewan Canada
- Palouse region
- Washington State
8Large-scale Grain Production
- Large-scale grain farms grew during Industrial
Revolution - Farms are usually highly mechanized,
capital-intensive operations - Several technological innovations precipitated
the growth of large-scale grain farming - McCormick Reaper 1830s
- Cuts standing grain in the field
- Combine Machine
- Completes all three processes
- Reaping, threshing, and cleaning
9Plantation Farming
- Definition
- Involves large-scale farming operations that
specialize in farming of one or two high-demand
crops for export, usually to more developed
regions - Called plantations or agricultural estates
- Introduced in tropical and subtropical zones by
European colonizers - Seeking to produce crops such as
- Coffee, tea, pineapples, palms, coconuts, rubber,
tobacco, sugar cane, and cotton
10Plantation Farming
- Today, plantation farming is largely reflective
of global power structures - Most exist in low-latitude regions of Africa,
Asia, and Latin America - Most owned by companies from more developed
countries - Often take the best land from natives
- Most plantations exist in a location that has
easy coastal access for export
11Plantation Farming
- Through modern plantations have integrated
advanced technology, still labor-intensive - Large number of seasonal workers used
- Form of plantation agriculture remains in the
subtropical and tropical U.S. - Migrant workers used for labor
12Commercial Gardening and Fruit Farming
- Predominant type of agriculture in the Southeast
United States - Region has a long growing season and humid
climate and is accessible to the large markets - New York, Philly, Washington D.C.
- Often called truck farming
- Truck means bartering or exchange of
commodities - Grow fruits and vegetables
- Sold fresh to consumers
- Highly efficient large-scale operations
- Labor costs kept down by hiring migrant workers
- Many undocumented
13Von Thunens Agriculture Location Theory
- Johann Heinrich von Thunen a 19th century
economist - Wrote book The Isolated State 1826
- Formulated model to explain and predict where and
why different agricultural practices would take
place around a citys marketplace - What it says
- Farmers consider which crops to cultivate and
which animals to raise based on market location - The farmer compares two costs
- Cost of land vs. cost of transporting goods to
market
14Von Thunens Model
- Based model on assumptions
- Assumed there was only one city with one, central
marketplace where all farmers sell their products - Assumed that the farmland is all equally farmable
and productive and there is only one type of
transportation mode - Also assumed no social customs or government
policies would influence farmers choices
- Given these assumptions, von Thunens model
allowed for only one variable to change in his
model - The distance a farms location was from the
citys market as evident in transportation costs
15Von Thunens Model
- In the model, the central marketplace is
surrounded by agricultural activity zones that
are in concentric rings - Each ring represents a different type of
agricultural land use - Moving outward from the citys central
marketplace, the farming activities change from
intensive to more extensive
16Von Thunens Model
- Reasons explaining the Models predictions
- Land closest to the citys marketplace is more
expensive per unit than is land farther away from
the citys center - A grain farmer who needs a lot of land for
his/her extensive farming operation is going to
purchase a farm further away from the citys
central marketplace because the land is less
expensive
- A milk producer is likely to buy land closer to
the citys center because he/she doesnt need the
extensive land a grain-farmer needs to produce
the same profit - Additionally, the dairy farm needs to be closer
to the marketplace so milk can be transported to
the marketplace for sale before it spoils - Grazing is often the land uses farthest away from
marketplace
17Von Thunens Model
- Usefulness of the Model
- Useful in comparing real situations to his
theoretical farming situation - One that is restricted to only one variable
(transportation costs) chaning - In the real world, agricultural land use patterns
depend on more than one variable
- Von Thunen knew his work was based on his
theoretical assumptions so he introduced some
variations - Existence of a river running through the city,
possibility of multiple marketplaces, idea that
soil was not equal everywhere in the model - Overall the model emphasizes the influence of
distance as a factor in human location decisions - According to Von Thunen, farming decisions, like
so many other spatial patterns, relate to
distance
