Soil & Water Management Webinar for Certified Crop Advisors

earn 4.5 hard to get Soil & Water Management CEU’s

Certified Crop Advisors in the state of Illinois looking for the hard to get Soil and Water Management credits should registered today for a University of Ilinois Extension Webinar. The soil and water management webinar will be held February 20 at locations around the state. Crop Advisors can earn 4.5 CEU’s, or Continuing Education Units, by attending. The cost is $45 and includes lunch and snack. The program runs from 9 to 2 Tuesday, February 20th. Check with your local Illinois Extension office for complete details.

Iowa Court Decision on Field Tiles | an interview with Jonathan Coppess

The Iowa Supreme Court has ruled drainage districts in the state cannot be sued for the cleanup of nitrates in drinking water. Justice Thomas Waterman authored the majority opinion, writing that policy deciding who pays for nitrate removal is the jurisdiction of Iowa lawmakers. This was a win for the drainage districts says University of Illinois Agricultural Policy Specialist Jonathan Coppess. However, he says the Clean Water Act implications of the suit, about whether or not field tiles are point sources that can be regulated, remains to be addressed.

“So the big question under the Clean Water Act, as I understand it, is the Des Moines Water Works is claiming that the agricultural stormwater exemption under the Clean Water Act does not apply to drainage districts. In this case, because once it comes through the pipes it becomes a point source.” –Jonathan Coppess, Agricultural Policy Specialist - University of Illinois

Again, the decision in the Iowa courts is that only lawmakers in the state can determine who pays for the cleanup of nitrates from drainage districts. It did not address issues related to whether or not field tiles should be subject to regulation under the Clean Water Act.

The Consequences of a Foot of Rain in June

The rainfall in May and June has put the corn crop in a difficult position this growing season. Late in June the corn crop in eastern Illinois north of Interstate 74 was under water. It looked bad, really bad. Oh there was some of it that looked pretty good, but not much. Things across the border in Indiana aren’t much better, and neither, apparently, is a large part of Missouri and southern Illinois. The crop has just gotten way to much water says University of Illinois Extension Agronomist Emerson Nafziger.

Quote Summary - This is one of those times when the consequences of having a foot of rain in June is not something we would want to ever have and this year it is going to have a serious affect on the crop.

There are two primary concerns related to corn. The moisture is a great haven for the development of disease. The other concern, and this may be more important moving through July and August, is that the root system of the crop hasn’t had any need to develop…not just the roots of the corn under water, but of the whole corn crop from Missouri to Ohio.

The closer we get to pollination the slower this root regrowth is and the less potential there is to recover a healthy root system on this crop say Nafziger,

This could come back to hurt the crop later in the season because it won’t be very resilient during periods of dry weather. A crop in the first week of August cannot grow its root system deeper. It does not have that capability.

If the system has been damaged, even if there is nitrogen and water left deep in the soil, it may not be able to access it and produce higher yields. There in lies a new concern for the water logged corn crop. It looks now as if there may be a change in the weather pattern. Mike Tannura of tStorm Weather in Chicago has been talking about this on the radio.

Quote Summary - A hot area of upper level high pressure is going to drive the U.S. weather pattern over the next couple of weeks and probably beyond that. It’s location is key. Right now we think it will center somewhere near Nebraska / Kansas and on to the west, which would just keep things warm, but not too warm. Any deviation in that system would lead to dramatic changes in weather forecast over the next few weeks.

So, too much rain has stressed the corn crop from Missouri to Ohio. It’s about to pollinate, and then begin grain fill. Even if the weather only turns hot, it could be a compounding problem.
