Iowa Crops and Weather Report
Iowa Secretary of Agriculture Bill Northey commented Monday, August 25, on the Iowa crop progress and condition report released by the USDA National Agricultural Statistical Service. The report is released weekly from April through October.
“The warm temperatures and needed precipitation last week helped both corn and bean crops. The crop remains in very good condition overall, with 75 percent of corn and 73 percent of beans in good to excellent condition,” Northey said.
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:
Much-needed precipitation limited fieldwork to 4.2 days suitable across Iowa during the week ending August 24, 2014, according to the USDA, National Agricultural Statistics Service. Above normal temperatures during the week aided crop development. Activities for the week included spraying for insects, baling hay, and hauling grain.
Topsoil moisture levels improved and rated 4 percent very short, 19 percent short, 73 percent adequate, and 4 percent surplus. Subsoil moisture levels rated 4 percent very short, 21 percent short, 73 percent adequate, and 2 percent surplus.
Eighty-eight percent of Iowa’s corn crop was in the dough stage or beyond, 17 days ahead of last year and 8 days ahead of the five-year average. Corn crop in the dent stage reached 33 percent, 25 percentage points above the previous year but 9 points below normal. Three-quarters of the corn acreage was reported in good to excellent condition. Ninety-four percent of the soybean crop was setting pods or beyond, 13 percentage points above last year and 1 point above average. With a few farmers reporting soybean leaves starting to turn color, 73 percent of the soybean acreage was in good to excellent condition. Oat harvest for grain was nearing completion, slightly behind the previous year and normal.
With the second cutting of alfalfa hay nearing completion, the third cutting of alfalfa hay was 46 percent complete, 11 percentage points below last year and 18 points below the five-year average. Sixty-four percent of all hay was rated in good to excellent condition. Pasture condition rated 56 percent good to excellent. Stress on livestock increased this week due to heat and flies.
