Cool conditions during planting season increase the potential for herbicide injury to seedlings due to slow emergence and reduced ability of the crop to metabolize herbicides. While herbicides may be responsible for emergence issues, most problems that have been brought to our attention seem to...

Every year is different. This year’s weather from January 1 to April 25 was cold and wet; a stark contrast to last year’s weather. While we know the differences in weather conditions every year, we do not know the implications on soil water and N at planting time. Field operations have just...
