In summary, irrigation is the process of using artificial methods to provide water to crops. Surface irrigation involves the use of gravity to spread water on crops, while localized irrigation utilizes a system of tubes and pumps to deliver water to plant roots.
WHEN WAS IRRIGATION FIRST USED? Irrigation is the watering of plants by artificial means. Without irrigation there could be no farming in dry regions. Very early in history, man learned how to move water. The ancient Egyptians, for example, practiced irrigation more than 4,000 years ago. The Egyptians at first carried water from the Nile River to their fields in jars. Later they learned to divert the water to the land through simple dams and canals. The early irrigation systems depended on the yearly flooding of the Nile. Irrigation was carried on by town dwelling Indians of New Mexico and Arizona long before the white man came to America.
