Drier Weather Aids U.S. Corn, Soybean Harvests; Rains Boost South American Crops

Posted on 10/22/2018 12:22 PM

Most of the wettest areas of the Midwest were dry during the weekend and harvesting of corn and soybeans probably advanced to more than 50% completed. There were some damaging winds that ushered in the drier weather and some areas did get some light showers to slow progress.

Most rains once again focused on the southeastern Plains this past weekend, especially central and eastern Oklahoma, and central and eastern Texas. Rains also spread across the northern Delta, and northeastern and southeastern Midwest. The active showers in the northern Delta and northeastern Midwest slowed corn and soybean harvesting a bit, while additional showers in the southeastern Plains maintained some wetness concerns, according to Radiant Solutions LLC.

Dry weather in the central and western Midwest and northeastern Plains allowed corn and soybean harvesting and remaining wheat planting to progress well, Don Keeney, senior meteorologist at Radiant Solutions, said in a note to clients Monday. Showers should remain very limited in these areas early this week, allowing fieldwork to continue to progress well. Light showers should build across the Plains and into the western Midwest midweek, before pushing into the central and southeastern Midwest late week. Those showers will slow fieldwork a bit, although no major set-backs are expected, Keeney said.

The biggest planting and harvesting problems will be later this week as remnants of Hurricane Willa move out of Mexico and into central Texas before continuing east into the Carolinas by late week and up into the Northeast by the weekend.  

In Brazil, rains increased across northern areas this past weekend, favoring western and eastern Mato Grosso, northern Goias, northern Minas Gerais, and southern Bahia, Keeney said. Rains are expected to spread across much of Brazil this week, with the heaviest amounts expected across central Brazil. The rain will continue to improve moisture for corn and soybeans development from eastern Mato Grosso to northern Minas Gerais, and into parts of western Mato Grosso do Sul. However, the heavier rains will likely increase wetness concerns again in eastern Mato Grosso do Sul, western Sao Paulo, and western Parana.

In Argentina, rain also increased across southwestern areas, especially western Buenos Aires and La Pampa, which improved moisture for corn and soybean germination during the weekend, Keeney said. Rains this week will further improve moisture for crops in central and northern Cordoba, and central and northern Santa Fe.

In China, showers favored central and southern Yangtze Valley and far southwestern North China Plain over the weekend. Showers should continue this week and return to northeast China. Rains in southern Yangtze Valley will maintain abundant moisture for wheat and rapeseed, while drier weather in North China Plain and northern Yangtze Valley favors corn and soybean harvesting, Keeney said. However, the drier weather there will stress winter wheat and rapeseed.  

A few showers favored southwestern and eastern Ukraine and western North Caucasus this past week and a significant upturn in precipitation across the region this week will help to improve moisture supplies and will favor late establishment of the winter wheat, Keeney said. More showers will likely be needed across southwestern Russia, and central and southern Ukraine.

A few showers during the weekend favored central and southern Spain, northern U.K. southern Italy, western Romania, northern Bulgaria, southeastern Poland, and Former Yugoslavia over the weekend, boosting soil moisture for winter wheat and rapeseed establishment. Cooler and wetter conditions in northeastern areas this week will maintain favorable field conditions. A significant upturn in showers is expected next week in western areas that will be welcomed relief from recent dryness, Keeney said.
