Topsoil moisture levels statewide rated 4 percent very short, 15 percent short, 73 percent adequate and 8 percent surplus. Levels in west central Iowa rated 4 percent very short, 8 percent short 84 percent adequate and 4 percent surplus.Subsoil moisture levels statewide rated 5 percent very short, 14 percent short, 73 percent adequate and 8 percent surplus. West central Iowa is faring better, with subsoil moisture levels at 2 percent very short, 8 percent short, 88 percent adequate and 9 percent surplus.

Iowa farmers planted 17 percent of the expected corn crop during the past week, three days behind last year and four days behind the 5-year average. Northern Iowa remains wet from melting snow which has slowed planting progress, however south central and southeast Iowa farmers already have at least 40 percent of their corn planted.
Soybean planting is underway with 2 percent of the expected crop in the ground, two days ahead of last year but equal to the average.
Sixty-two percent of the expected oat crop has been planted, eight days behind both last year and the 5-year average. Just 10 percent of the crop has emerged, almost two weeks behind last year.
The extended winter season has left hay in short supply for some livestock producers. Pastures in many areas need rain to spur growth.
