Responding to Flood Issues on the Farm

Monday, June 23, 2008

This morning, a conference call for producers affected by flooding was conducted by Purdue Extension and the Indiana State Department of Agriculture. The following is a summary of the issues discussed that seemed pertinent to Owen and Clay counties.

Locally, it would not be suggested to try to replant corn. In most every case except where a stand was totally or mostly wiped out, a poor stand will have a better outcome than a replanted stand at this time. Other issues with corn include the mud found in the whorl. Some producers wanted to mow the corn with the idea that the growing point is below the mowing height and one could rid the mud from the plant.

This is not recommended. Fungi will be a problem either way and mowing will not reduce problems. Corn in flooded areas will be more susceptible to fungal diseases and therefore will need to be watched more so for fungal disease development and be better candidates for fungicide treatments later in the season as one typically makes fungicide application decisions based on hybrid info and later moisture and evening temperature data later in the season. Most importantly at this time, one can try access the growing point and determine corn stand loss. Typically any corn under water for three days or greater with the heat that occurred would be lost. Corn that has been underwater but has survived is typically showing yellowing. This is a combination of lack of oxygen and could also be nitrogen (N) loss. Some have been using N toolbars to loosen soil and try to get oxygen into the soil without applying additional N. While a guessing game, it would be appropriate to apply 50 additional pounds of N in these areas and the tool bar pass may also help to break the soil for aeration.

On the soybean side, a 40 percent stand somewhat evenly distributed is worth keeping rather than replanting at this time. After June 10, one begins to lose 1.4 percent of yield potential per day. After June 20 locally, one should consider moving the maturity group up about by a half group (i.e. if group 3.3 normally then move to 2.8 area). Since for every 3 days soybean planting is delayed the result is 1 day delay for maturity/harvest, one should increase seeding rate 15-20 percent to compensate for this loss in the number of nodes developed. A thicker stand will also encourage plants to grow taller which will aid in increasing the pod set distance from ground level.

Wheat growers will want to be cautious when harvesting to not get any wheat that has sprouted in the head as most elevators have a low tolerance for or reject wheat with sprouted kernels. Sprouted wheat could still have some value for livestock feed. For those with forages and/or livestock, issues and alternatives were discussed. Fence loss was incredibly high and one should document these losses with pictures, measurements, time and cost for repair should assistance become available. Annual emergency forages include sorghum-sudan grass and pearl millet. These are tough to bale for hay as they are high moisture. Foxtail millet would be a better choice for hay.

Please note the 8 a.m. forums this week. These 90-minute forums will include FEMA applications and other emergency assistance application information. Locally, either Bicknell (Tuesday, June 24) or Martinsville (Wednesday, June 25) are options.

The Friday, June 20 conference call is available on the internet if one would like to listen to that 60-minute event.

You can contact the local Purdue Extension Office by calling 829-5020 Ext. 14 in Owen County or 448-9041 in Clay County for more information or publication copies regarding this week's column topic or to RSVP for upcoming events. It is always best to call first to assure items are ready when you arrive and to RSVP for programs.

While most publications are free, some do have a fee. All times listed are Eastern Time.
