cotton
oil crops:

what are the 4 most important environmental factors?
climate, elevation, soil, & topography
tropical
equal periods of daylight/nighttime, 100+in. Of rain/yr., avg. temp: 64°F
dry
less than 14 in. of rain/yr, temps: 25-100°F
temperate
all 4 seasons, long summers, short winters
continental
all 4 seasons, but more inland so less impacted by the oceans
polar
COLD, dry
mediterranean
MDCs, Commercial, Mixed between Intensive and Extensive
Where: Mediterranean Sea, West Coasts of continents (California, Chile, & South Africa)
Crops: horticulture–fruit, flowers, and veggies, some animal raising, some wheat production (in drier areas)
Most important crops: grapes and olives
Intensive
think intense): using every single inch as much as possible, A LOT OF WORK
Rely on heavy levels of “inputs”
Chemical fertilizers, pesticides, growth regulators, human labor, animal labor, natural fertilizers, etc.
Why? A LOT OF MOUTHS TO FEED, paid a lot of money for the land (none can be wasted)
Extensive
not using every single inch as much as possible
Few inputs and little investment into labor
Why? Didn’t pay a lot (can waste a little)
