To grow a lot of food, a lot of water is a must.
Farmers have been using irrigation systems for centuries.
Well ever since farming has came into practice.
10,000 years ago Maize was domesticated.
From that point agriculture and the art of farming has grown.
There are two different types of irrigation.
Surface irrigation and sprinkler irrigation.
Surface irrigation is the application of water directly onto the surface of the fields.
Picture from http://ga.water.usgs.gov/edu/irfurrow.htmlThis is accomplished by flood irrigation, furrow irrigation or gated pipe. These three are all the the same basic method just slightly different systems are used. Surface irrigation is the oldest form of system type irrigation. (In dry land farming, watering is all dependent upon the rain.) Read more about Furrow Irrigation here.
The second type of irrigation is sprinkler irrigation. This type uses pipes and sprinkler heads to water the fields.
Under this type there is many systems.
Solid Systems aka hand lines.
Hand lines are what I grew up moving. They are no fun, yet must be done every morning and night.
