Cover Crop/Soil Health Field Day-Tour Scheduled for September 19th in Southeast Nebraska


Learn about cover crops being used in different cropping systems at a NRCS Demonstration Site, a SARE On-Farm Research and Education Experimental Site and a Nebraska Grazing Lands Coalition Site. 



Nebraska Extension, North Central SARE, NRCS, and the Nebraska Grazing Lands Coalition are sponsoring a Cover Crop Field Day/Tour on Tuesday, September 19th.  The field day/tour will start at the Daryl Obermeyer Farm east of Auburn. Registration is at 9:00 with refreshments; followed by the program beginning at 9:30 a.m.Daryl’s Farm is one of several demonstration farm sites across Nebraska that the NRCS has established to evaluate soil health principles and the impact of cover crops on soil health in different cropping systems.  At the demonstration site Stephen Kennedy, District Conservationist from Nemaha County and Aaron Hird, Soil Health Specialist from NRCS will discuss and demonstrate soil health principles, explain the project at this site and answer questions about this program in Nebraska.  Participants will have the opportunity to view the plots at this site.  Daryl has a corn, soybean, wheat rotation with cover crops planted following each crop. The above photos show the cover crops growing following wheat and the corn and soybeans which will be harvested this fall.



The second stop on the tour is the Rob and Trent Bohling Farm.  This is the site of a North Central SARE Research and Education Grant that the University of Nebraska-Lincoln is conducting with the Bohlings.  In this on-farm research project, cover crops have been incorporated into a cropping system and the impact of cover crops and grazing cover crops is being compared to no cover crops on the impact on soil health and crop yields.  Humberto Blanco, UNL Soil Scientist will discuss research that is being conducted at this site and in Nebraska and the impact of cover crops and grazing on soil physical properties and crop yields.  Mary Drewnoski, Beef Systems Specialist, Nebraska Extension, will discuss the feed value of cover crops, the economics of grazing cover crops and potential nitrate issues in grazing cover crops. We will also be serving lunch at this site.  Participants will have the opportunity to view the cover crops here as well.  Above are photos of the cover crop growing and a plot without the over crops.  Crop yields and soil data is being collected from this experiment. 
GLC #1
The final stop on the tour will be at the Rod Christen Farm, with the site being southwest of Tecumseh where Rod has a Cover Crop Demonstration site as part of the Nebraska Grazing Lands Coalition (NGLC) Demonstration Project.  Rod, Ron Bolze, NGLC Coordinator, Mitch Stephenson, UNL Range Management Specialist and Nate Pflueger, UNL graduate student working will have a report on this project.   This field day is free to the public.  While pre-registration isn’t required, it is encouraged for lunch.

Bio-Based Weed Control

Blaster #1
 Watch a webinar this next Thursday, July 27th at 10:00 a.m.  Dr. Sam Wortman, Assistant Professor, Department of Agronomy and Horticulture, University of Nebraska-Lincoln will present a webinar on “ Bio-based weed management tools for specialty crops.” Sam will discuss some of the research he has conducted with cover crops and other methods of weed control in organic specialty cropping systems.  This meeting will be recorded.
Here is the link to the Zoom Meeting  and also the meeting ID #     
Meeting ID: 730 760 379


Blaster #2
Dr. Wortman conducted research at the University of Illinois with this weed blaster.  His research started in the greenhouse where he used grit to blast weeds.
Blaster #3
From the greenhouse, research moved to outside plots.  Dr. Wortman evaluated the effectiveness on weed control in garden crops. The machine above was used to blast weeds. 
Pulling weeds
Hand weeding is still a method of weed control in organic production. This can be expensive and time consuming as well.  In organic production there are several methods that can be used for weed control.  
Black Plastic
The combination of several management strategies for weed control is the best path to success.  Black plastic has been used for several years as a reliable method of weed control. 


Blaster #4
A large scale mechanical blaster is being used for weed control by this farmer.
Cover Crop #1
Many farmers are using mixtures of cover crops in their cropping systems.  While being much more expensive, will it be cost effective to use a mix?  Dr. Wortman will discuss his research on cover crops in the webinar.  


Cover Crop #2
A mix of 18 cover crops is being evaluated. 


Cover Crop #3.png
Mustard produced the most biomass in the spring monoculture and spring mix.


Cover Crop #4
In the summer, sudan grass produced excellent biomass in a monoculture and in a mix as well.



This is an excellent opportunity to learn about bio-based weed control methods in organic specialty cropping systems. Let people know about this webinar that may be interested in learning more about this topic.  This Zoom meeting will be recorded.  




Green School Farms – Gary Fehr

Much has happened since I conducted this interview last fall with Gary Fehr.  Earlier this winter, Gary’s wife, Shannon Moncure, passed away following a courageous battle with cancer.  Shannon was a strong advocate for local food and served in several different capacities on the Nebraska Food Coop Board.  She was instrumental in getting this Cooperative established.  Shannon was also a strong supporter of sustainable agriculture. Shannon served on the Nebraska SARE (Sustainable Research and Education) Advisory Committee. This blog is in memory of her.  I wish Gary the best of luck as he follows his dream of developing his farm and continuing to produce local food organically for the community of Lincoln and other people in southeast Nebraska.

In this blog post I am interviewing Gary Fehr of Green School Farms. Gary produces food organically on a farm he rents west of Lincoln, NE, just off of West Van Dorn St.  Gary has marketed his produce through a number of methods, including a CSA, wholesale farm distributors and a local school  since he began farming. Follow along with this photo blog as we tour the farm.


Gary put together this makeshift high tunnel or you may call it a medium tunnel.  It is taller than a low tunnel, but not nearly as big as a high tunnel.  It serves its purpose though of being a season extender to crops.  This is out on the garden site west of Lincoln.  (photo Gary Fehr)

2016-06-27 10.31.54jpg.jpg

A well was dug to provide irrigation water to the garden site. Water is  essential for the successful production of local food in southeast Nebraska. In most years at least some supplemental water is needed to raise a good vegetable crop.

2016-04-05 13.01.54

Gary grew several types of greens and salad-type vegetables that he marketed through his CSA, the Nebraska Food Coop and schools. (photo Gary Fehr) 2016-04-18 21.16.17.jpg

Here is an image of a snail. Snails, slugs and other critters can become pests, foraging on different crops, especially salad greens. These pests can be kept out of gardens by using different types of materials, i.e saw dust, egg shells, ash and sand and nut shells. (photo by Gary Fehr)

2016-05-04 08.24.41.jpg

You can see from this photo that Gary planted several different varieties of greens.  Being an organic grower, Gary utilized several different methods of weed control. Notice the cereal rye growing between the rows of his crops in his garden site. Cereal rye has been shown to be beneficial as a cover crop, particularly  for suppressing weeds. It can also be used as a windbreak, protecting young seedlings from hot, south winds. (photo Gary Fehr)

2016-05-14 12.57.47.jpg

Gary uses an old drill to crimp down the cereal rye.  This makes an excellent weed barrier and also keeps the soil cooler during the hot summer to reduce evaporation from the soil surface.  (photo Gary Fehr)

2016-05-14 12.50.39.jpg

Cereal rye after it was crimped down by an old drill in Gary’s garden spot.  The rye needs to be at least in the flowering stage when it is crimped or else it will come back and try to produce seed. Research has shown the cereal rye is beneficial in suppressing weeds and some diseases. The above ground biomass adds carbon to the soil and the roots underground do the same. When the roots die there will be more pore space which improves water infiltration and  water storage in the soil. (photo by Gary Fehr)

2016-06-05 11.24.24.jpg

Another cover crop that Gary incorporates into his garden rotation is hairy vetch. Hairy vetch is a legume that fixes nitrogen and provides significant nitrogen (100 lbs of N/ac) for the subsequent crop, i.e. a high nitrogen user like corn.

2016-05-15 15.54.46.jpg

As an organic grower Gary used several different materials to mulch the vegetables in his garden.  Cardboard can be used to smother weeds and old hay can be used to cover soil to reduce competition from weeds and also add organic matter to the soil.

2016-07-31 08.06.26.jpg

Gary grows a number of different crops throughout the growing season of spring-summer-fall. Drip Tape is used to water the crops during the drier parts of summer.

2016-09-24 08.45.02.jpg

Some of the summer crops that Gary grew in 2016 included sweet corn, peppers, and water melon. (see photos above taken by Gary Fehr)

2016-09-26 06.18.48.jpg

From the photos above, you can see that peppers were a staple in Gary’s Green School Farms garden.  He planted several different varieties and they were excellent producers.

2016-09-09 11.03.18.jpg

2016-09-05 12.48.21.jpg


Another important crop at Green School Farms was tomatoes (see photos above) Gary grew several kinds of tomatoes up until the first killing frost in the fall.


Gary even grew some Okra on his farm. Although he had a limited number of plants, they produced well for him. (see photos above)

2016-09-08 22.04.24


Cantaloupe was a good crop for Gary, producing in the late summer and into the early fall. (see photos above)


Early in the fall Gary planted salad greens.  In the photo above he covers some of his crop to protect it from a freeze.  Notice the companion flowers growing next to his crop. As an organic grower Gary uses different plants that attract beneficial insects that are predators for pests or some plants that repel and protect the crop from harmful pests.


One last crop Gary plants and sells that will keep for use in the winter is butternut squash.  This popular squash is used several ways in various dishes and soups for people that love local food. (see photo above)


A photo taken near the end of the growing season at Gary Fehr’s Green School Farms in west Lincoln. I know Gary purchased some land near Raymond, NE and hopes to move his farm out there in the future. I wish Gary the best of luck as an Organic Farmer and Local Food Producer in southeast Nebraska, I hope for many years to come!  Good Luck Gary!!!!

Webinar Scheduled for Thursday, April 6th at 10:00 a.m. on Permaculture

Nebraska SARE is sponsoring a webinar on April 6th  from 10:00 – 11:00 a.m. Central Time on Permaculture. The link to this webinar is listed below:

Meeting ID: 853 147 857

The title of the webinar is: “Nebraskan Permaculture Design, Trees as the Farmer’s Best Friend, & Other helpful tips”   By Gus von Roenn, Permaculture designer, builder, urban farmer, activist, educator, land steward, event planner and nonprofit founder.

Please tune in to this webinar to see how the concepts of Permaculture can be applied to the unique circumstances presented in Nebraska. Permaculture is the pursuit to feed, shelter, transport, and energize your life in your community without compromising the integrity of the world’s living environment. Working with nature allows us to achieve our goals with minimal maintenance. Poorly designed landscapes, buildings and technology that attempt to counter the forces of nature add complexity to our lives and create dependence on a complex system that needs maintenance.

Gus is an advocate for permaculture and sustainable practices throughout Nebraska. He works through many organizations like the Nebraska Farmers Union, the Sierra Club, Nebraskans for Solar, Nebraska Sustainability Agricultural Society, the Metro Omaha Food Policy Council and Omaha Permaculture to elevate the discussion of issues surrounding healthy food accessibility, land stewardship and entrepreneurship in low-income communities. His academic background is in anthropology, sociology, archaeology and permaculture while working in landscaping, photography and home remodeling to pay off school. Currently, Gus is a certified permaculture designer with his own Permaculture design consulting firm and landscaping crew to install the designs. He is also the founder of a nonprofit called Omaha Permaculture that accepts degraded, vacant land for restoration while providing space to incubate agriculture-related entrepreneurial opportunities.  As an advocate for everything Permaculture and sustainability in Nebraska, he likes to help many organizations teach their constituents the limitless opportunities that create abundance in all of our communities for all of us to share.  You can learn more about Gus and permaculture at and This webinar will be recorded. If you have questions about this webinar, feel free to contact me at or (402) 274-4755.
