On October 2nd, James Adkins came to our class to talk about the state of irrigation in today’s farming world. Currently, about twenty percent of the world’s farmland is irrigated, and about forty percent of the world’s food supply is from irrigated land. Asia is home to around sixty eight percent of the world’s irrigated land, and this compares to the United States’ claim to about seventeen percent of the world’s irrigated land.
Some different types of irrigation include the flood irrigation, where water flows across the soil where the crop grows by gravity on the surface, drip irrigation, where black tubing is laid across the ground in rows where the crops are and drips water drown to the roots, and central pivot irrigation, where a large machine pivots in a circle and sprays water from multiple hoses. This central pivot technique is seen a lot on farms here in Delaware.
