Drought Continues, Harvest Wrapping Up

The fall harvest season has been almost unbelievable in the Upper Midwest during September and early October, with almost perfect fall harvest weather conditions. In fact, the long string of very warm, sunny days with very low humidity and virtually no precipitation has been almost too perfect. These very unusual 2012 harvest conditions have led to corn and soybeans drying down too fast, poor fall tillage conditions, and a very high danger for field fires. The extremely warm, dry weather pattern has resulted in a rapid completion of both soybean and corn harvest in most areas.

As of Oct. 8, soybean harvest was virtually completed in most portions of southern and western Minnesota, except for some areas with later-planted soybeans. Overall, most reported soybean yields for 2012 were average to slightly below average, with yields in the eastern portions of south-central Minnesota and in southeast Minnesota being slightly higher. The whole-field yields in most other areas were better than expected, given the ongoing drought conditions during the 2012 growing season, but were generally slightly below long-term average yields. Locations that received some timely rainfalls during late July and early August had some better soybean yields.

 

Corn harvest has also progressed rapidly in most portions of southern Minnesota, with nearly 80-90% of the corn harvested at many locations, as of Oct. 8. Corn yields across the region have been highly variable in 2012, as a result of the widespread rainfall events at various locations during the growing season. There have been isolated whole-field yield reports of over 200 bu./acre; however, there have also been yield reports of 120-130 bu. in the same general area, with even lower yields in some locations. Differences in planting date, corn hybrid, crop rotation, soil type and storm damage have also helped account for some of this yield variation. When the 2012 corn harvest is completed, farm operators in southern Minnesota will likely end up with yields that range from near average to 20-25% below average, depending on field conditions.

The good news for all producers regarding the 2012 corn harvest is the low harvest moisture of the corn coming out of the field, and the high quality of the corn. Most of the corn being harvested in south-central Minnesota in the past few weeks has been at 13-17% moisture, meaning it can go directly to farm grain bins without additional drying, or can be hauled to grain purchasers with very little price dockage for excess kernel moisture. The rapid field drydown of the corn is saving most farmers $25-30/acre in anticipated corn drying costs. Most of the corn being harvested has a test weight that is at or above the standard test weight for corn of 56 lbs./bu.

The rapid drydown of the soybeans this fall has led to some hidden costs for farm operators. Many of the soybeans this year were harvested at a field moisture content of 8-10%, which is well below the desired harvest moisture content of 12-14%. Harvest losses during combining increase significantly at those very low moisture contents, with harvest losses of 2-4 bu./acre not unusual when harvesting below 10% moisture.

The biggest soybean harvest loss may occur when the soybeans are sold at grain elevators. Soybeans are priced on the basis of 13% moisture. When soybeans are sold below that level, the farmer loses the value of the extra weight that is lost. For example, selling soybeans at 8-9% moisture compared to 13% moisture results in a loss of approximately 70-80¢/bu. at a soybean price of $16/bu.

Weather condition play a very important role in the farming industry. It not only affects harvests, but also affects the quality of feeds for the cattles. Drought is a fine example of a weather condition that greatly affects crops because when water is lacking, crops condition deteriorates.
