Iowa soybean farmers with questions about late planting, yield projections, crop insurance and other topics now have new website to turn to for answers. The Iowa Soybean Association has compiled a Soybean Planting Brief--a list of frequently asked questions with answers pertaining to the late 2013 planting season. You can go online to access the information and list of guidelines.
Depending on when Mother Nature will allow planting to resume on a wide scale, soybean farmers will need to make some tough economic and agronomic decisions in the days and weeks ahead. The Soybean Planting Brief will help.
It contains the latest information from Iowa State University Extension and Outreach on possible yield implications for planting in mid-June or later. Crop insurance information pertaining to planting deadlines is included, along with economic consequences for late planting or not planting at all. Extension specialists emphasize that farmers need to keep a line of communication open with their crop insurance agent. ISA says it will continue to provide Iowa growers up-to-date information during the prolonged 2013 planting season. Click here to view the Soybean Planting Brief.
Current rain delay for planting continues as of June 11 in many areas of Iowa
In northwest Iowa, Paul Kassel, Iowa State University Extension field agronomist at Spencer, reports that most farmers in his area have not been in the field since May 24. There have been a few nice days since, but the nice days are usually followed by an inch of rain. "There continues to a lot of interest in the prevented planting crop insurance option on corn," he told Wallaces Farmer. "Some of the large acre operators are really behind on corn planting. And the weather continues to work against them."~~~PAGE_BREAK_HERE~~~
ISU Extension field agronomists report they are getting lots of questions about fields that have corn herbicides already applied. One often-asked question is in reference to the "prevent plant option" for crop insurance. Products like Dual II Magnum, Outlook or low rates of Verdict do not pose a problem when farmers want to switch from corn to soybeans, says Kassel.
Consider herbicide restrictions if you want to switch from planting corn to beans
Some other products are not labeled for soybeans and are therefore technically illegal in this situation where these herbicides are already applied and you want to switch to beans. The straight acetochlor products like Harness and Surpass pose a fairly low risk problem when soybeans are planted. The herbicides SureStart and TripleFLEX pose more of a problem since they contain a product called Stinger. Soybeans are quite sensitive to Stinger. Corvus or Balance Flexx also present more of a threat to damage soybeans. The factors that will lessen the potential for soybean injury from all of these products are the time since application, amount of rainfall received, and the amount of tillage you do prior to planting the beans.
ISU field agronomists are encouraging farmers check their fields for stand establishment. Some cornfields look really good. Others--not so good. The areas in fields that have poor drainage are struggling. "Some of those areas will have to be replanted," says Kassel. The threshold for replanting corn is 16,000 to 20,000 plants per acre this time of year. However, none of these areas that need replanting will be that easy of a decision. Farmers will have to drive the fields and drop the planter in where there are some blank spots. It is difficult to make a decision in that situation.
Soybeans that were planted during the week of May 13 look quite good, says Kassel. "However, there are a lot of soybean fields yet to be planted," he adds. "There are a lot of last year's cornfields that have not yet seen a tractor this spring."
