Better pic from the top of the levee today. Started irrigation on this hot SOB yesterday afternoon. The levee is adjacent to the river that is the supply for irrigation water. Right now I am pushing water on 50 acres.
Our fields are cut to grade with .15 ft of fall down the row, with .07 ft of side fall. Think of a pool table slightly tilted to one corner pocket. Most crops in the Delta are planted on raised beds to prevent young seedlings from spring rains, and for irrigating the middles during the summer.
There is an extensive system of underground pipe buried on my farm, with a riser in each field. Water is pumped in by a diesel powered centrifugal pump. There are 7 risers on my place that can be turned on and off individually. Poly pipe is tied to the hydrants on each riser. Once the hydrant is turned on, water is released into the pipe, and a hand tool is used to poke holes either every middle or every other, depending on the crop and the amount of pressure available. In cotton we will water 2-3 times per year depending on rainfall, soybeans 3-4, corn 4-5. The poly pipe is 15” diameter and 2 mil thickness. At the end of the year it is picked up and recycled to make trash bags.
