Rootless corn is easy to diagnose – simply dig up plants that are not standing erect like they should be, then gently knock off the soil to get a look at the roots. With rootless corn you will see the...
Sandy to clay soils have different hydrological properties such as wilting point, field capacity, and saturation level (Fig 1a). Wilting point means no water is available to plants, field capacity means near optimum moisture for plant growth, and saturation means the soil pores are full of water...
The Forecast and Assessment of Cropping sysTemS (FACTS) webpage is evolving. When it was launched in 2015, FACTS provided forecasts soil moisture, nitrogen, phenology, and crop yields at two Iowa locations. In 2016, it was expanded to six Iowa...
Planting conditions in April were pretty good for planting. In fact, there were many reports of planting in early April. Unfortunately, April was much cooler and dryer than normal. Early planted corn and soybean took longer to germinate and emerge because of these cooler conditions. Additionally...
While the warm weather has finally arrived for planting season, dry soil is becoming an increasing concern in parts of the state. In addition to concerns about subsoil moisture, some fields have had significant surface drying, particularly in areas with more tillage this spring. Dry soil...
The concern for not having enough water during the 2021 growing season is increasing. Observations from Iowa fields (i.e., deep soil samples and tile drainage experiments), and analytical frameworks (i.e., Drought monitor) indicate below normal moisture in parts of Iowa. Here, we benchmark the...
With cool weather conditions potentially causing delays in cover crop termination, what options are available? Cereal rye ahead of soybean is not nearly as problematic. While planting green may not be advised for beginning cover crop users, more experienced cover crop users have...
Choosing a corn seeding rate is as much art as it is science because soil conditions and seed quality can greatly affect the outcome. The goal is to choose a seeding rate that produces an economical optimal yield as opposed to the maximum yield. A seeding rate has to factor in seed quality,...
The nice weather and dry conditions have led some to think about the start of planting. My opinion, it is too early. Remember crop insurance replant dates are not until April 11. Use the extra days to get plans in order and a little rest and relaxation before the pace picks up.

Over the last 5-years the Northwest Research Farm near Sutherland, IA has been conducting row spacing by plant population through cultivar trials with two different brands. The trials were not designed to compare brands, but rather provide another comparison to evaluate soybean row spacing and...

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...
