Unit 5: Agriculture Flashcards
agriculture
the purposeful cultivation of plants or raising of animals to produce goods for survival.
climate
long term patterns of weather in an area (temperature and precipitation)
factors of agriculture
temperature, precipitation, elevation,soil, topography
close to the equator=
growing season all year round
bid rent theory
high value land= purchase less and use intensively (high yields)
low value land= purchase more and use extensively
survey methods
metes and bounds, long lot, and township/range
metes and bounds survery
spread through relocation, uses natural features to set boundaries (ex: stream, river, forest, etc.)
long lot survey system
divides land into narrow (linear) paracels stretching from rivers, roads, and canals.
- allows for equal access to resources/transportation
-French areas of US
township and range survey system
based on grid system (6x6, 1 mile sections)
- dispersed land designed for the Land Ordinance by Thomas Jefferson
inputs (used to intensive)
chemical fertilizer, pesticides, growth regulators, etc.
types of intensive agriculture
-plantation
-mixed crop/livestock
- dairy
-Mediterranean
- intensive subsistence wet rice
- market gardening
monoculture
crop rotation every season
-restores nutrients, raises stakes, increases yields, must invest in inputs
truck farming
serves market distance from farm
- mexico/south US
on the farm mixed farming vs between
on: crop/livestock raised on the same farm
between: share resources
Extensive subsistence
nomadic herding and shifting cultivation/slash and burn
