DES MOINES – Iowa Secretary of Agriculture Bill Northey today commented on the Iowa Crops and Weather report released by the USDA National Agricultural Statistical Service. The report is released weekly from April through October.
“The warm dry weather has allowed crops to continue to develop, but many areas of the state are now starting to need some rain,” Northey said. “Some areas of the state did receive some precipitation yesterday and there are additional chances later this week. Hopefully crops will continue to receive timely rains throughout the growing season.”
The weekly report is also available on the Iowa Department of Agriculture and Land Stewardship’s website at www.IowaAgriculture.gov or on USDA’s site at www.nass.usda.gov/ia. The report summary follows here:
Crops were beginning to need rain as dry weather continued the week ending July 21, 2013, according to the USDA, National Agricultural Statistics Service. It was the third week in a row with below average precipitation, which has caused soil moisture conditions to decline, and has led to crops needing additional moisture. Statewide there was an average of 6.7 days suitable for fieldwork.
Statewide, 43 percent of topsoil was in the adequate and surplus categories, a decline of 22 percentage points from the previous week. Topsoil moisture levels rated 14 percent very short, 43 percent short, 42 percent adequate and 1 percent surplus.
