Chlorosis field day Monday near Blomkest

BLOMKEST -- There will be a field day Monday on recent research on iron deficiency chlorosis management in soybean near Blomkest.

The event is organized by the University of Minnesota Extension and will be at the southeast corner of the intersection of U.S. Highway 71 and Kandyohi/Renville County Line Road. Registration will begin at 9 a.m. with speakers starting at 9:30 a.m. and ending by noon.

Speakers present will discuss the basics of the chemistry behind iron deficiency chlorosis in soils, research trials conducted by the University of Minnesota in the last five years, a plot tour and discussion on current efforts in iron deficiency chlorosis management in soybean and presentations from sponsors on efforts for increasing soybean yields in western Minnesota.

Iron deficiency chlorosis is a major production issue affecting many soybean acres in western Minnesota. Current research has focused on utilizing newly available iron fertilizers applied with the seed or planting a companion crop with the soybean. Two strip trials were established in 2010 to study the effects of four management strategies identified by previous research to potentially increase yields in the presence of iron deficiency chlorosis.
