Interest Leans To Increased Irrigation
If drainage is already taken care of across the farm, then increasing irrigated acres may be the next step, which would explain the way the votes fell. For the 62 percent of the respondents who may increase their irrigated acres, Mississippi State University offers the following pointers about soil moisture, rainfall and irrigation.
"Most crops can utilize 2.5 to 3 feet of soil profile to extract moisture. This gives a growing plant 2.5 to 3.5 inches of available water to carry it without additional rainfall. Emerging crops use little moisture early in the season, and a good moisture profile will carry these plants for about a month without supplemental moisture.
"As the crops get larger and begin to canopy, a full profile will only last about eight to 14 days. This typically begins to occur in early June through August. Rainfall is the best hope for supplemental moisture since it is free, but it is not 100 percent effective. To determine how effective a rainfall is, use a soil probe, shovel or another device to see how deep the moisture soaked. As much as 75 percent of the water from a hard fast rain can run off, whereas a slow steady rain can soak in as much as 90 percent. The type of rainfall event determines its effectiveness as well as the amount of moisture already in the soil.
