Less than a year ago, area farmers were attending a 'dry-weather' meeting about the possible impact the summer's heat will have on crops and cattle.
On Tuesday, approximately 30 crop producers and others associated with farming attended a meeting about late planting and replanting options due to a very wet spring.
Paul Kassel, SU Extension agronomist from Spencer, provided information on yield loss and moisture content at harvest.
In a handout and a presentation from Kassel, attendees learned that a late June corn planting compared to the average May planting date reduces corn yields by 25 percent or 45 bushels per acre. Grain moisture at harvest also increases by 15 points.
The risk of frost before black layer is 100 percent when planted June 25 or later.
The positives of planting in early June is there is usually less corn rootworm.
Kassel pointed out the obvious that nitrogen losses have occurred. However, it is difficult to know how much has been lost even with a late spring nitrogen test.
He said farmers should consider an in-season application of 30 to 40 pounds per acre of additional nitrogen.
Concerning soybeans, Kassel said producers could usually expect a 25 percent yield reduction with a planting date of June 20. The actual soybean yields may be 350 to 40 bushels an acre. Kassel suggests using an early group II variety from June 15-20 or a late group I variety of soybeans from June 15 to July 1.
Nicole Tifft, from Farm Credit Services of America, talked about crop insurance options.
With final plant days of May 31 for corn and June 15 for soybeans, the late plant period is considered 25 days after the final plant date-June 25 for corn and July 10 for soybeans.
Tifft said crop planted during the late plant period loses 1 percent of the guarantee for each day late. However you only lose the guarantee on the portion of field planted during the late plant period.
If planted after the late plant period, the guarantee is reduced to 60 percent of the original guarantee.
"If you know you're not going to plant, it's best to let the insurer know right away," she said.
Larry Lago, Farm Service Agency director for Emmet and Dickinson counties noted the final field crop report date is July 15. While producers can file after that date, there is a fee for late filing.
