Wet weather slowing farmers in new growing season

USDA, NASSWet conditions continued to slow down fieldwork in Iowa during the week ending April 12, according to the USDA, National Agricultural Statistics Service.  Statewide there were 2.7 days suitable for fieldwork. Producers in west central Iowa had 2.6 days suitable.

Parts of Iowa experienced snow during the week and cool soil temperatures remain a concern.  After a slow start, farmers in northern Iowa continued to apply anhydrous, while applications in the southern two-thirds of the state were winding down.

Soil moisture, 2nd weekTopsoil moisture levels at the beginning of the growing season are much more favorable than in the previous two years. See the accompanying graph.

Topsoil moisture levels statewide rated 2 percent very short, 17 percent short, 76 percent adequate and 5 percent surplus. West central Iowa is just a bit wetter, with ratings at 1 percent very short, 9 percent short, 87 percent adequate and 3 percent surplus.

Subsoil moisture levels statewide rated 2 percent very short, 20 percent short, 75 percent adequate and 3 percent surplus. Those ratings in west central Iowa were 2 percent very short, 12 percent short, 85 percent adequate and 1 percent surplus. North central Iowa reported the highest soil moisture levels with topsoil and subsoil moisture levels rated 95 percent and 87 percent in adequate to surplus, respectively.

One-quarter of the state’s expected oat crop (62 percent in west central Iowa) was planted during the week ending April 12.  Statewide, 42 percent of oats have been planted, five days ahead of last year, but slightly behind normal. Four percent of oats have emerged, five days ahead of last year, but six days behind the average.

Pasture condition rated 41 percent good to excellent.  Pastures are greening up, but use by livestock has been limited due to slow growth.  Livestock conditions were reported as mostly good with some reports of calving nearing completion.
