Most corn producers have planned their spring N program for 2015, and many have already started to implement their program. Such plans might include fall ammonia application, early spring application of ammonia or another form of N, or plans to apply all of the N at or after planting. In recent years there has been a trend towards more applications per crop, and it’s not unusual today to have N applied three or four times on the same field.…
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.…
Soybean farmers who take a ten-minute online survey will help University of Illinois crop scientists and Extension educators to better understand how decisions are made in their farms regarding soybean management and inputs and to tailor programs and projects to improve yields and profitability.
Villamil requests that soybean farmers take the survey by April 10.
The survey is a collaborative effort between the Department of Crop Sciences in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois,…
Along with the continuing emphasis on getting soybean planted early – in late April to early May – comes the question of soybean maturity rating, and whether early planting benefits fuller- or shorter-season varieties the most.
Planting date
Figure 1 was updated with the 2014 data from our planting date trials in central and northern Illinois. The change compared to the response I showed a year ago is mostly from the large response to delayed planting at Urbana in 2014.…
In April 2014 I wrote on the topic on N fertilizer on soybeans, reporting that our research at the University of Illinois has rarely shown a benefit in yield to applying N fertilizer during the middle part of the season. But it seems that some people, perhaps reacting to testimonials of high yields after using N fertilizer in the high-yield conditions of 2014 remain convinced that adding N fertilizer “makes high yields higher.”
Of course, most producers who got high yields –…

Cover crops have many benefits to the soil,…
In June with wheat harvest underway, I asked people to send in grain samples so that under an NREC-funded project we could measure P and K levels to try to sharpen up our nutrient removal numbers.
We got a few wheat samples. We also, thanks to the Illinois Soybean Association, found a way to get a good number of soybean samples to measure P and K after they are tested for protein and oil.
Our real need now is to get corn grain samples from the 2014 harvest.…
Signs and symptoms of a few soybean diseases have begun to show up in the last few weeks in some areas of the state. Two of these diseases, sudden death syndrome (SDS) and Sclerotinia stem rot (a.k.a. white mold) certainly are going to cause economic losses in some growers’ fields this year.
Symptoms of SDS that currently are being observed are interveinal chlorosis and necrosis of the leaves (veins remain green while the tissues between the veins turn yellow and then brown). …
