Activity at the Liqui-Grow Agronology 10 Research Center on 29 March 2012 included the application of our early spring dribble nitrogen and the application of our pre-plant herbicides for both corn and soybeans. We added 35 oz./A of Instinct to our dribbled 86 and 136 lbs. N/A applications since we have been having these…

On 21 March 2012, the 1st day of spring, the Mississippi River temperature was reported at 61º F. Generally in early spring, the river temperatures will be close to the morning 4-inch depth soil temperature. For your consideration, I have included the data in Table 1 which reflects the average last 32º F temperature…

A post application of a fungicide and an insecticide on soybeans can be worthwhile. The application needs to be made at the R3 growth stage for the soybeans. Our data, Table 1, for the two years, 2009 and 2011, demonstrate an approximate $10.00 per acre net increase for the management decision to spray. Table 1 …

Why should you rush to plant your 2012 soybeans early? According to Dr. James Specht, a University of Nebraska researcher, the following list is why you should plant soybeans early:
To capture more seasonally available solar radiation (sunlight)
To transpire a greater fraction of the seasonally available water
More nodes…

The Iowa State University current optimum soybean planting recommendation for the southern 2/3 of Iowa is the last week of April and first week of May for the northern 1/3 of Iowa. Purdue researchers also indicate that a 3-day delay in planting will cause a 1-day delay at harvest. At our Agronology 10 Research Center…

In your soybean seed selection process, “yield” is still number one. But, in 1989 I experienced a 21 Bu/A yield difference between a susceptible and moderately resistant variety for Brown Stem Rot at the Agronology 10 Research Center. Risk management is an extremely strong second factor. This means we need to match known history of…

For many of our soybean producers, a hope and prayer is the extent of their management efforts for their soybean crop. I would suggest we continue to pray for our crop, but add a more comprehensive approach to dealing with our soybean management needs. My list of management needs for soybeans include:
Plant early…
