Cover crops + soil microbes + weed seeds = ?

Recently Karen Renner has begun working with MSU’s soil biologist, Lisa Tieman, to explore how cover crops influence the microbiology of the soil and weed seeds. Last week we put tiny mesh bags of weed seeds into an incubation experiment hoping to gain some preliminary information. It is always exciting when different disciplines come together to try to understand a system. After one week of our bags being in the incubators we had some germination and growth of giant foxtail and velvetleaf. We removed the seedlings (pictured below), but it will be interesting to see if germination correlated to any of the factors that Lisa and her team are measuring…stay tuned.

2015 Sugarbeet planting & new graduate students

Wednesday, April 15th, 2015

And so it begins. Today we were able to plant all of our sugarbeet studies at the Saginaw Valley Research and Extension Center and put down our preemergence herbicide applications. This year’s studies at SVREC will focus largely on controlling glyphosate-resistant Palmer amaranth and horseweed/maretail within this glyphosate-tolerant crop.

You will also notice in the photo below one of our new Master’s students, Kelsey Rogers, who will be studying the management of multiple-resistant Palmer amaranth in soybean using a combination of herbicide programs and a rye cover crop. Also joining the team is Dan Wilkinson who will also be working towards his M.S. Dan’s project will focus on herbicides containing the new active ingredient bicyclopyrone. Both Kelsey and Dan began their coursework this January.

Cover crops following soil-applied herbicides: Fall update

Friday, September 12th, 2014

-E. Hill

 

Due to an increasing demand for information regarding rotation restrictions for cover crops following field crops we have set up a field experiment on campus. Soil applied soybean herbicides were applied in late-May and cover crops were planted at the end of August; ~15 weeks after herbicide applications. The cover crops of interest this year include: medium red clover, oilseed radish, and cereal rye. We will be tracking the progress of these cover crops through visual estimates of injury, stand counts, percent cover, and biomass throughout the fall and spring. Check out a few preliminary pics below. Preliminary results will be discussed at winter extension meetings and at the North Central Weed Science Society cover crop symposium in December.

2014 Organic Dry Bean Webinar: Archived and available for viewing

Thursday, May 1st, 2014

At the end of March, Jim Heilig and I presented a webinar through eOrganic regarding the findings of our two dissertation research projects. The webinar was titled “Breeding efforts and cover crop choices for improved organic dry bean management.” The cover crop component specifically addresses how weeds were impacted by clover, oilseed radish, and rye cover crops, in comparison with a no cover crop treatment.

Organic field day- September 2013

Monday, September 9th, 2013

-E. Hill

 

I had the opportunity to present some of my latest and greatest results from my Organic Dry Bean Production Systems research at 3 of my on-farm locations. We traveled from Columbiaville to Caro and then all the way over to Alma, MI. It was a great opportunity to share the impacts of cover crops on dry beans with local organic growers. The impacts discussed included: nitrogen availability, weed population dynamics, and yield. Stay tuned for more results coming on this project as we begin the 3rd, and final, year’s harvest. We will also be presenting at the Organic Agriculture Research Field Day at the Kellogg Biological Station on October 10, 2013.
