Some rain has fallen somewhere in Illinois nearly every day for the past 3 weeks, and rainfall totals for this period exceed 7 inches – two to three times normal – over more than half of the state (Figure 1). This has a lot of people wondering if enough nitrogen remains in the soil to supply the corn crop.
Daily high temperatures have averaged close to normal over the past three weeks, while night temperatures have been 3 to 4 degrees above normal,…
Rainfall in April and May has been about average through most of Illinois, at least until the downpours the last days of May. This has allowed timely planting and a good start to the crop in most areas, and has allowed nitrogen management to be carried out more or less as planned by most producers. Warm temperatures during some weeks of May are moving crop development along, and much of the N planned for application after crop emergence has already been applied.…
A lot of anhydrous ammonia is going on this spring, and in many fields the hope is to plant as soon as practicable after NH3 application. This brings up the question about potential for NH3 damage to seeds and seedlings.
Seed and seedling damage from spring-applied NH3 is relatively rare in Illinois, but it can be quite damaging, and we want to minimize the chances of it happening. Such damage is rare is because NH3 converts readily in soil to the ammonium form (NH4+) which is held on soil exchange sites and is not damaging to plant tissue.…

The corn crop in Illinois is off to a good start in many fields, and in most areas is in the V5 to V8 growth stages, just starting its rapid growth phase. On average, the crop under good conditions will add some 200 lb of dry matter per acre per day over the next 80 days or so. It will take up 3-4 lb per day of nitrogen before pollination, after which the N uptake rate will slow.…
