Corn planting progress continues, with 23% of the Illinois crop planted by April 25, and planting continues with some rain delays the last week of April. The warm temperatures that finally arrived will be good for emergence of both corn and soybeans, but there are some reports of damage to early-planted soybeans from frost on April 21 and 22.
Warmer soil temperatures will start the mineralization process by which microbes release N from soil organic matter,…

In the week ending on April 18, planted acreage moved up in Illinois, from 5 to 12% for corn and from 2 to 5% for soybean. The forecast for cool temperatures this week has turned even cooler, with highs in the 40s for several days, and with frost possible, including temperatures that may drop into the upper 20s in some places in mid-week. There may be some snow as well, which as it melts will move as cold water into the soil.…

Planting is off to a fast start in Illinois, with 5 percent of the corn crop and 3 percent of the soybean crop planted by April 11 (NASS). With the exception of much of western Illinois, where heavy rain fell on April 8-9, most of Illinois remains dry, and planting continues, but with some concern about low temperatures that persist.
Temperatures the first half of April were close to average, but were above average the first week and below average the second week of the month.…

“Every agronomic decision is a good one for someone” is a quote that I saw recently that reminds us that being “entrepreneurial” is high valued in today’s business world, rewarded in some cases by large amounts of venture capital invested in startup companies. That’s as true in crop agriculture as in any other business, and it means that startups are under pressure to find or create niches and product(s) to fill them, and to demonstrate that these products are widely sellable.…

As we indicated in a recent Bulletin article, nitrogen applied as anhydrous ammonia in the fall is an effective source of N for the corn crop, but is also a little more subject to loss compared to N applied in the spring. One of the main factors that determines how much of the fall-applied N is subject to loss is how much of the ammonia converts to nitrate (is nitrified) in the fall and early spring,…
