Upright ears: cause for concern, debatable

An ear of corn that fails to droop holds a lot of water in a wet fall and can breed some notable late season problems.

Corn ears normally remain erect until black layer but shorter ear shank lengths, desirable as a corn borer defence prior to Bt traits, have increased duration for some hybrids. Although agronomists contend that the effects of upright ears on fungal infections may not be as pronounced as farmers think, the November 2 cropline report advised that mould issues may be more prevalent than earlier vomitoxin survey reports suggested. Experts are also watching for sprouting grain quality issues, recommending that farmers segregate the worst fields and market them accordingly.

But just because a hybrid had upright ears this year, doesn’t necessarily mean it will again next year, so farmer’s shouldn’t cancel seed orders unless yield results start to weigh in.

Reducing soybean harvest losses

Skilled combine operators can capture additional profits of more than $150 per hour of harvest but field losses are commonly about 10 percent of yield, sometimes as high as 20 percent, due to careless harvest operation. With only 10 percent of combine operators checking their adjustments regularly to match field conditions, those losses could easily be reduced to 3 or 4 percent.Researchers and extension officers are urging farmers to pay close attention to reducing soybean harvest losses this fall. Typically more than 75 percent of soybean machine harvesting losses are gathering losses, so greatest attention should be given to proper header adjustment and operation. This includes maintaining ground speeds of 3 mph maximum, running the reel about 25 percent faster than ground speeds (increasing to 50 percent when beans have lodged), and positioning the reel axle 6 to 12 inches ahead of the cutter bar.

Potash investors’ loss is farmers’ gain

There’s a lot in the news to suggest the breakup of a Russian potash cartel last July may result in significant crop input savings for farmers. Thomson Reuters suggests potash prices are poised to drop 20% and that Malaysian and Indonesian buyers, heavily dependent on potash for palm oil production, continue to wait for cues from China or India. Further hints point to Chinese prices, which usually set the market low, as potentially $320 a tonne. A Globe and Mail article quotes other dire predictions from Robert Winslow, a National Bank Financial analyst, that bumper corn and soybean crops will force potash prices to fall regardless of the activities of any oligopoly. But the same article also presents the position of Agrium chief executive Michael Wilson, who feels the market is overreacting to the news and isn’t assuming any specific price drop values.
