Starter fertilizer can be used to complement pre-plant fertilization of crops to increase yield and economic returns to production. However, its use will not be beneficial in all production conditions.
Spring is the time to pay close attention to stored grain. This year, there is more wet corn in storage, and there has been a rapid weather switch from cold to warm. Check now and often to prevent future problems.
Volunteers are needed for springtime cutworm moth data collection.
The loss of organic matter and its nutrient value by erosion has significant effect on both the long-term sustainability of the soil nutrient pool and soil productivity. Nutrient availability in the soil to plants is inherently linked to the soil organic matter pool that is replenished through plant-animal-soil-atmosphere interactions, creating different pools of organic matter.
The interest in cover crops has increased recently due to the benefits they can provide to the corn-soybean cropping system. The use of residual herbicides has increased at the same time, and the potential impact these herbicides may have on establishing cover crops is an important consideration.
Seed treatments are becoming more and more commonplace on soybean. Moreover, the number of products available to treat soybean is increasing. In 2014, soybean seed treatment trials comparing 15 commercial products were completed at 3 locations in Iowa with funding from the Iowa Soybean Association. This article reports the results of those trials.
A new seed treatment, Clariva™ Complete Beans, is available to manage the soybean cyst nematode (SCN). Iowa State University personnel and staff of the Iowa Soybean Association On-Farm Network® conducted 24 experiments across Iowa in 2014 assessing the effects of the new seed treatment on yield and SCN soil population densities. Results are reported herein.
Winter winds can cause soil erosion, resulting in the loss of top soil and organic matter. Cover crops and tillage can help reduce the amount of erosion that occurs during the winter months.
Name change for Pesticide Safety Education Program (PSEP) reflects program’s purpose.
Crop Advantage Series provides the latest information to promote profitable decision-making for upcoming growing seasons. Programs will be held at 13 locations across the state during January.
Warren Pierson has been named the new coordinator at the Field Extension Education Laboratory (FEEL) at Iowa State University.
Recent issues with biotech events not approved in some world markets have renewed the need for maintaining required management (stewardship) of biotech grains. As a producer, the most important step in a controlled-market stewardship chain is the initial delivery from the farm to the correct first point of sale. Taking this step protects the continued availability of upgraded traits at a pace faster than otherwise might be allowed.
This is the time of the year when tillage becomes the number one priority for some, whether they need it or not. Even though tillage may be needed in certain situations and field conditions, a well-managed field and proper crop rotation may not call for tillage.
Annual conference for producers and ag business professionals scheduled for December. Participants reminded to register early; enrollment is limited.
Meetings provide timely crop pest and nutrient information. Register online for meetings to be held in Ames and Iowa City.
Iowa farmers have hundreds of SCN-resistant soybean varieties from which to choose. ISU’s annually updated list of SCN-resistant varieties in maturity groups 0, I, II, and III is now available and there are more choices than ever before.
These learning modules focus on the development of fungi in the field and the production of mycotoxins in the under specific environmental conditions.
Fall is a great time to collect soil samples for testing for soybean cyst nematode (SCN). Sampling guidelines are provided in this article.
It seems like a broken record...weather changes have shifted expectations of new crop corn quality. Field drydown is probably nearly over so do not expect much change in moisture from here on.
While a significant change in grain price may be troublesome, it may or may not affect recommended rates because of current N price. Read more to plan for your 2015 crop.
Consider soil temperatures before fall application to corn fields. Cooler temperatures will provide better results.
Updated Oct. 2, 2014. Every year brings on a new set of challenges for harvest and grain management; in the past five years we have gone from very wet to very dry. Overall 2014 crop quality is likely to be good with a few uncertainties because of weather.
Cover crops are being grown in Iowa for soil and pest management. The possible effects of cover crops on the soybean cyst nematode (SCN) are discussed in this article.
Part of Iowa’s 2014 corn crop may be at risk of a killing frost before reaching maturity. April planted corn has no to low risk while May planted corn will have varying levels of risk.
As the 2014 growing season draws to a close, agronomists and farmers are reminded to scout for stalk and ear rots of corn.
Several soybean diseases have popped up over the past several weeks across Iowa. Some of the more common diseases found in our field scouting can be found in this report.
The planting date for wheat is important for discouraging Hessian fly. Read more about the biology of this pest and how to avoid crop injury.
With corn pollination complete and grain fill well underway, estimates of corn yield are being made across Iowa. Here, results are presented from a project using Hybrid-Maize to forecast yield potential at the end of the year.
This growing season corn rootworm numbers have been lower than the past several years. This article reviews current management tactics and offers guidelines for the 2015 season.
The annual fall field day for the Iowa State University Southeast Iowa Research Farm near Crawfordsville will be held September 9, 1:30 p.m.
Brown stem rot has recently been found in Iowa soybean fields. This disease can be confused with sudden death syndrome, so it is important to know what to look for when scouting fields.
Now is the easiest time to find new infestations of Palmer amaranth and initiate programs to either eradicate or limit its spread. We appreciate being informed of new Palmer amaranth infestations and are willing to aid in identifying suspect plants.
Soybean aphids are becoming more abundant in fields this week. Scout soybean now to make timely treatment decisions.
Show the world how well you know your weeds!
With corn pollination underway and in some case near completion many agronomists and farmers are now beginning to think about what corn yields will be. Here, results are presented from project using Hybrid-Maize to forecast yield potential at the end of the year.
Crop Advisors can earn continuing education credits for CCA certification through in-person and online attendance of the Resilient Agriculture Conference, August 5-7, in Ames, Iowa.
Iowa State University Extension and Outreach, in partnership with national precision ag leaders and Meister Media, will hold an Ag Big Data conference on August 25, 2014 on the ISU campus.
The Iowa N response database in the Corn Nitrogen Rate Calculator was recently updated. There are now 246 trials for corn following soybean and 133 trials for corn following corn.
