Irrigation
The Central Valley Project Rainfall diminishes from N to S Water is pumped out and sent along smalle
r 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 c
an 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
