In 2014, Iowa Learning Farms and Practical Farmers began a joint research effort to investigate the use of a highboy seeder to seed cover crops into standing corn and soybeans. The objective was to determine the effects of planting technique on the successful establishment of sole species and mixed species cover crops. Cover crop planting […]

Using a roller-crimper to terminate cover crops is a topic that has garnered A LOT of attention in recent years. At our 2016 annual conference, three farmers shared their experiences with using modified equipment to roll cover crops. This year, Levi Lyle (of Keota) and Billy Sammons (of Churdan) explained how they’ve used actual roller-crimpers […]

Ahead of our annual conference last month, we held a short course titled “Conserving $$ and Soil.” Often the conservation of farm production input costs and soil might be considered at odds with one another. Soil conservation efforts are thought to cost money to implement and/or they might involve producing less which would in turn lose […]

Winter Cereal Rye Cover Crop Effect on Cash Crop Yield: Year 8 is now available! This is a long-term project being conducted by Iowa Learning Farms and Practical Farmers of Iowa. Between 2009 and 2016, 12 farmer-cooperators have contributed to 59 site-years of on-farm research to investigate what effect a cereal rye cover crop might have to […]

Last week, we released a new research report, “Cereal Rye Cover Crop Termination Date Ahead of Soybeans, 2016 Update.” The cooperators involved, Jeremy Gustafson and Jack Boyer, saw no ill effects of planting soybeans within 5 days of terminating a cereal rye cover crop. They were both able to reap some cost savings in weed […]

Delaying cover crop termination until near soybean planting would allow for more biomass production by the cover crop in the spring presenting the opportunity for more environmental benefit. Two farmer-cooperators continued work they began in 2015 that compares terminating a cereal rye cover crop 2-3 weeks prior to seeding soybeans (early termination) with terminating the […]

In a Nutshell
• Delaying cover crop termination until
near soybean planting would allow
for more biomass production by the
cover crop in the spring presenting the
opportunity for more environmental
benefit.
• Two farmer-cooperators continued
work they began in 2015 that compares
terminating a cereal rye cover crop 2-3
weeks prior to seeding soybeans (early
termination) with terminating the cover
crop within 5 days of seeding soybeans
(late termination).
Key findings
• Jeremy Gustafson saw a 2 bu/ac increase
and improved weed control with
the late termination treatment in 2016.
This amounted to a $49.97/ac economic
benefit compared to the early termination
treatment. In 2015, soybean
yields were equivalent between the two
termination date treatments.
• Jack Boyer saw no difference in soybean
yields between the two cover
crop termination treatments in either
year. In 2015, he was able to skip a
post-emergence herbicide application
which saved him approx. $40/ac.

 

RESEARCH REPORT

We’ve been having a lively discussion on the PFI cover crops email discussion list about sudden death syndrome (SDS) in soybeans and whether cover crops may be reducing incidence of this disease. I reached out to Dr. Leonor Leandro, ISU Plant Pathology and Microbiology, who studies SDS in Iowa, to see if she had anything to […]

Practical Farmers of Iowa’s mission is to strengthen farms and communities through farmer-led investigation and information sharing. One of the primary ways we accomplish this mission is through on-farm research as part of our Cooperators’ Program. Over the past few years, the investigation of cover crops by farmer-cooperators has dominated the program. Below I offer a review […]

Objective: To test effects of roller crimping and an organic bio-soil enhancer on weed suppression, cover crop winter hardiness, soil properties, overall plant health and soybean (Year 1) and corn (Year 2) yields.
