---in Southern California Modern Farming ---in Southern California

Location Latitudes: between 30°N and 40°N Western part of the U.S. Coastal Area Southeastern part is desert area (Mojave Desert)

Characteristics Limited Rainfall (below 250mm) Water Shortage Sandy Soil and high evaporation rate Hilly Relief except in the valley Small Population High technology level Support from the government

Government is willing to provide grants and subsidies to the farmers Income

∴Modern Farming Methods are widely used

Agricultural technology Irrigation Biotechnology Chemical fertilizers and pesticides Mechanization

Irrigation The Central Valley Project Rainfall diminishes from N to S Water is pumped out and sent along smaller canals or pipes to the farms in Southern California. Dams are built to hold back the spring meltwater and released slowly during Summer

Biotechnology Produce crops that can resist pests and diseases Improve the nutritional contents of crops Improve the flavour and texture of crops

Chemical fertilizers and pesticides Chemical fertilizers are widely used  soil fertility Pesticides, insecticides and fungicides are used to control pests and diseases

Sprinklers Common Sprinklers used in Central Valley

Another type of Sprinklers:

Another irrigation method:

Mechanisation --- Tractor

Crop Rotation

Farmlands in California:
