Rainfall slows fieldwork last week

Iowa growers have planted 65 percent of the expected corn crop, and soybean growers have 33 percent of the expected crop in the ground, according to the USDA, National Agricultural Statistics Service.

The Iowa Crop Progress and Condition report is released by the USDA National Agricultural Statistical Service weekly from April through November. The report can be found at

The report issued Monday for the week that endedSunday states:

Iowa farmers were held to 3.8 days suitable for fieldwork after storms left measurable rainfall across much of the state during the week ending May 13.

Topsoil moisture levels rated 2 percent very short, 6 percent short, 69 percent adequate and 23 percent surplus.

Subsoil moisture levels rated 4 percent very short, 10 percent short, 69 percent adequate and 17 percent surplus.

Intermittent rain interrupted fieldwork and planting activities in portions of the state, but recent rains have failed to relieve the dry soil conditions in the southern one-third of the state.

Iowa growers have planted 65 percent of the expected corn crop, four days behind last year. While the southern two-thirds of the state already has 79 percent or more of the corn crop planted, north central has almost three-quarters of the crop left to be planted. Twenty-six percent of the crop has emerged. In southeast Iowa, 91 percent of the corn has been planted, and 58 percent has emerged.

Soybean growers have 33 percent of the expected crop in the ground, led by farmers in southeast Iowa who have planted almost two-thirds of their expected crop. Five percent of the crop has emerged.

Ninety-two percent of the expected oat crop has been planted, one week behind last year and three days behind the five-year average. Sixty-one percent of the crop has emerged, six days behind last year, and five days behind the average. In southeast Iowa, 99 percent of oats have been planted and 82 percent have emerged.

Rain and warm temperatures have benefited hay acreage and pasture conditions statewide. The first hay condition rating of the season was 4 percent very poor, 5 percent poor, 34 percent fair, 45 percent good and 12 percent excellent. Pasture condition rated 49 percent good to excellent, an increase of 9 percentage points from the previous week.

Cattle and sheep are grazing on permanent pastures in many areas and farmers are waiting for drier conditions to take their first cutting of hay for the year.
