With the prospect of continuing high prices, "cotton is $50 ahead of soybeans and corn when you put the pencil to it,” says Darrin Dodds, assistant Extension professor of plant and soil sciences at Mississippi State University.
Irrigation assistance tool
Among the tools available, Dodds notes, is the Phaucet computer program for furrow irrigation systems using flexible polypipe.
“It’s somewhat time consuming to set up and enter data, but reports from Arkansas indicate water savings in the 25 percent range. That’s significant, not to mention reduced energy costs for pumping water.
The program will determine the diameter of holes to punch in a given section of pipe, calculate pressure changes along the pipe, adjust hole sizes for different row lengths in the same irrigation set, evaluable different layout options for a field and the irrigation pipe, and provide more uniform watering of a field in a shorter time period.
Use of the Phaucet program is one the acceptable measures for new well permit requirements in the state of Mississippi.
