The Integrated Crop Management (ICM) conference and Crop Advantage Series programs have been mainstays of Extension agronomic programming for many years. It is regretful that because of the COVID pandemic, those programs will NOT be offered this coming December and January. We are offering a new...
Save money and time this fall by planning for no-till soybean planting next spring. Many farmers are moving away from tillage, due to a host of detrimental environmental factors involved with tillage as well as reducing cost of soybean production.
Soybean yields are not impacted by no-...
Following the derecho event on August 10, millions of acres in Iowa face challenging conditions. In many cases the corn may be unharvestable. These unharvestable fields require some level of fall management to ensure the future crop can achieve even emergence and normal early plant growth.
...Fall Management Options for Corn Fields That Are Unharvestable
Millions of corn acres have been damaged by the derecho on August 10. Unfortunately for some of these acres, harvest will not take place. Decisions regarding fall management options will need to be made in the...
Low rainfall and high temperatures recently have caused some drought stress on local crops this summer. This is not wholly unexpected and there are some strategies crop producers can do to minimize the damage.
Higher nighttime temperatures cause plants to have higher nighttime respiration...
In 2018 and 2019, research was conducted on a relay intercropping and double cropping systems to evaluate as a possible alternative to Iowa’s traditional corn-soybean or continuous corn cropping system.
There were 2 sites; one near Kalona and another near Ames, Iowa, to study these...
Each year, decisions on planting date and cultivar selection are the major deciding factors on yield potential. Under current, year-to-year variable weather patterns and future climate change these decisions have become much more important. And there is a known knowledge gap on how future...
For a couple of years, some Iowa farmers have noticed lower yields along the southern and/or western edges of their fields. The low yields along the border tend to be prevalent when soybean, hay, or pasture are growing adjacently to the field on the southern or western edge. This phenomenon...
Since July 1 high humidity and temperatures have been scorching Iowa. Okay, maybe that is a little extreme. June has led to dry conditions across much of central and southwest Iowa. Heat and dry weather are not desired weather conditions in the 2 weeks before or after pollination. This four-week...
Many farmers and agronomists are noticing short soybean this spring. Some are pondering if there is something that can be done to spur some additional growth as flowering is fast approaching, if not already begun. The surprise with short soybean is that planting was timely. The unfortunate...
Radiation is down up to June 1 according the latest FACTS extrapolations.
The springtime decreases in radiation—especially in May—could have caused yellowing corn leaves and slowed down leaf appearance rates (radiation and moisture play a role in phenology, even though temperature is the...
With the weather Iowa has recently experienced and the time of year it is, we all can expect to see purple and yellow corn and even some tattered leaves: the ugly ducklings of your field. Don’t fret just yet, cooler temperatures and wet conditions are all contributing factors to the mosaic...
