Emerson Nafziger

We hope that we’ve seen the last of the snow by now, but both air and soil temperatures remain below average in Illinois heading into the second half of March. According to the Illinois State Water Survey (http://www.isws.illinois.edu/warm/soiltemp.asp) minimum temperatures 4 inches deep under bare soil ranged from the low 30s in northern Illinois to the mid-30s in southern Illinois the morning of March 17, and with some sunshine on that day, reached the upper 40s to low 50w in southern Illinois but did not get above the low 30s in the northern part of the state.…

Aaron Hager

Nature reminded us earlier this week that even though we select meeting dates well in advance, the weather often determines whether or not we can actually hold the meeting. Our long streak of good fortune came to an end this week as the adverse weather and road conditions forced us to reschedule two Classic meetings. The Classic meeting at the Urbana I Hotel and Conference Center originally scheduled for January 6 has been rescheduled for January 28. …

Yield Loss on the Edge of Corn Fields in 2013

December 9, 2013
Emerson Nafziger

We have been receiving reports since corn harvest began this fall about an unusual phenomenon: yields of the outside 8 to 24 rows on the south or west edges of corn fields show lower or much lower yields than corn farther into the field. The damage tends to be relatively uniform down or across the field, and is on field edges that border a soybean field, road, ditch, or another short-growing crop (such as forage legumes or grasses) other than corn.…

The Surprising 2013 Soybean Crop

December 8, 2013
Emerson Nafziger

The 2013 growing season in Illinois was wet early with delayed crop planting, good rainfall in June and July, mostly cool conditions in July, and little rainfall in August and September, with some high temperatures in late August and in September. With late planting and cool weather at times in mid-summer, seedfillling began only in mid-August, 10 days to 2 weeks later than normal, and took place during a period of very little rainfall. Our expectation for such a season,…

Potash Fertilizer: Is There a Problem?

November 21, 2013
Emerson Nafziger

In a publication brought to the public’s attention by news release from the University of Illinois several weeks ago, S.A. Khan, Richard Mulvaney and a colleague in the Department of Natural Resource and Environmental Sciences at the University of Illinois challenged a number of basic tenets of soil fertility, especially practices related to use of potassium (K) fertilizer. Citing hundreds of references and thousands of reported studies, they asserted that: K fertilizer is generally unnecessary in soils like most of those in Illinois;…
