We irrigate most of our crops in the Arkansas Delta

Rice: 1.5 million acres - all irrigated

Corn: 350,000 acres – 80% irrigated

Cotton: 1 million acres - 75% irrigated

Soybeans: 3 million acres - 62% irrigated

Milo: 250,000 acres – 50% irrigated

4.5 million irrigated acres – 74% of total acres

Phaucet Program For Furrow Irrigation

  • Helps determine size of holes to punch in tubing
  • Calculates pressure change along the tubing
  • Can help address different row lengths in the same set
  • May increase number of rows irrigated in a set
  • Should help rows water out more evenly

Can possibly reduce irrigation and runoff

Phaucet Program and Surge Valve Combination

Reduced pumping by average of 25 %
