Nitrogen Watch 2013 launches
In poorly-drained soils, denitrification is the main mechanism of loss. This process is fastest when soils are warm and near or at saturation. I use May 1 as a day representing when soils have warmed enough for this process to be significant, although soils were cooler on that date this year than they normally would be. Only a smattering of areas along the eastern side of the state are currently on track to have major N problems on poorly-drained soils.
Many people have not yet applied N fertilizer this year. That’s good because the N is safe in the bin or the tank. It’s bad because there is going to be a lot to get done in a short time.
We are now (May 14) at or near planting conditions over much of the state, and my bets are on the producers who plant when conditions are right and apply N (or finish applying N) later. This may require a shift in equipment or N source.
