August 2013 weather summary and 2013 harvest considerations


Weather summary. After the wet spring, June, July and August all saw precipitation totals much below the thirty year average (Figure and Table).  At the Northwestern Illinois Agricultural Research and Demonstration Center (NWIARDC) the last appreciable rainfall occurred at the end of July, with August precipitation totaling only 0.18 inches (Table).

Unseasonably cool temperatures prevailed for the first two thirds of August.  These temperatures masked the stress that both corn and soybeans were exposed to during this time due to very dry soil moisture conditions.  However, starting around August 20th, temperatures became more seasonable and much hotter.  These warmer temperatures and sustained dry soil conditions led to the rapid development of stress symptoms in corn.  Many leaves in the upper canopy have curled, while leaves in the lower canopy have begun dying and drying down.

Many counties in western Illinois have now graduated officially from being abnormally dry to either moderate or severe drought conditions (Figure).  In driving North through eastern Iowa and western Wisconsin over the Labor Day holiday, it is evident that dry conditions prevail over many Midwestern states.  According to the U.S. Drought monitor, as of September 3rd, 63 percent of Iowa was under at least moderate drought conditions and 32 percent under a severe drought.  In Minnesota and Wisconsin, 53 percent and 35 percent of these states, respectively, are under at least moderate drought conditions.  In Illinois, 39 percent of the state is under moderate a drought.

Crop Insurance. It may not be all that uncommon this year for a farming operation to be able to claim losses under federal crop insurance for both prevented plant acres this spring and drought losses this fall.  As time marches ever closer to grain harvest, employees of the USDA-FSA remind us about how important it is to keep good production records, particularly if an insurance claim may be in your future.
