Rain and recent snow melt across Iowa delayed harvest and other fieldwork progress as farmers were held to 4.5 days suitable for fieldwork during the week ending Nov. 24, according to the USDA, National Agricultural Statistics Service. Propane shortages across the state remain an issue as farmers try to dry their corn due to high moisture content.
Topsoil moisture condition statewide was rated 1 percent short, 83 percent adequate and 16 percent surplus. Ratings in west central Iowa were 89 percent adequate and 11 percent surplus.
Subsoil moisture condition across the state was rated 2 percent short, 82 percent adequate and 16 percent surplus. Ratings in west central Iowa were 88 percent adequate and 12 percent surplus.
Eighty-six percent of the corn for grain crop has been harvested, 10 days behind last year and two weeks behind the 5-year average. Producers in the northwest, north central and southeast districts have harvested 90 percent or more of their expected crop, while harvest in the northeast and south central districts were below 80 percent complete. In west central Iowa the corn harvest was 87 percent complete. Moisture content of field corn being harvested for grain was at 19 percent.
Livestock producers have been feeding hay and continue to allow cattle to graze on corn stalks. The increase in temperatures this past week reduced stress on livestock.
