Peter Scharf, University of Missouri, said, "After a long, wet spring, I’m getting questions about possible nitrogen loss from all over Missouri and even from other states.

My column with a ‘Nitrogen Loss Scoresheet’ in the last issue of the IPCM Newsletter provided one possible tool for evaluating risk and making decisions. Deep soil samples provide a more accurate and specific answer, but are hard work to get and require waiting while the lab work is getting done." More information.

In his travels to the ISU research farms west of Ames this week for research work, it is clear that corn is recovering and beginning rapid growth, but that growth is very uneven and varies on a quite small scale.
