Update of Annual Ryegrass Website and Blog

The annual ryegrass website has served a purpose for many years, but the reliance on embedded content has made the site too wordy and ponderous.

So, in the next month, we will be slimming the site down considerably. Instead of each Tab page being a lengthy educational piece, we will instead link to informed resources, including flyers, articles and other websites.

The annual ryegrass blog has until now been a separate website. In the next move, we will combine the blog with the website, as it provides the user with more convenience.

We would enjoy hearing from you about these changes. Let us know  what kind of information you would like to get, if in fact it hasn’t been there before.

As cover cropping continues to grow, the Oregon Ryegrass Growers want to continue to provide you with good information that is current and accurate.

Annual Ryegrass Helps Weed Control in No-Till Acreage

There are times when evidence from on-farm research, from growers, differs from evidence from university plots. Earlier this year, the long brewing animosity over annual ryegrass emerged again, when Purdue University weed scientist Bill Johnson again claimed that the cover crop is a tough-to-control weed.

Evidence from the field, going back 20 years, suggests otherwise. In a No-Till Farmer article earlier this year, magazine founder and editor Frank Lessiter said that growers tend to follow what works, No-Till Farmer’s benchmark study last year found that 28% of growers seeded annual ryegrass as a cover crop in 2016.

Mike Starkey, former president of the Illinois Soil and Water Conservation District Association, said Purdue has unfairly painted annual ryegrass as a nuisance. In his experience, no-tilling 2,550 acres and using annual ryegrass as a cover crop on all but a sliver of his cover cropped acres, he has found no problem controlling annual ryegrass. In fact, he said that annual ryegrass helps to control other weeds in his fields. “We don’t have many weed concerns, but annual ryegrass suppresses the weeds we do have,” says Starkey. “It also scavenges nitrogen, improves our soil structure and aids in the movement of air and water in the soil.”

Van Tilberg 2011 Hi-Boy Seeder2Dan Towery has promoted annual ryegrass and a host of other cover crops in his decades of work as an agronomist and crop consultant.He said he thinks that Purdue has gone overboard with their objections to annual ryegrass. He maintains some Purdue folks rely too much on what they’ve learned from their own research plots, are not big believers in no-till and have refused opportunities to see how growers are making annual ryegrass work.”

Thinking about Annual Ryegrass This Year?

It’s still not too late to consider starting a cover crop on your acreage this year. In fact, August may be an ideal time to broadcast seed.

In years past, the use of fixed wing aircraft to apply seed has been increasingly popular. Fast and effective, you can put seed on 1500 acres in a day if you have the seed located close to your fields.

Jamie Scott owns a 2000 acre farm and he started using annual ryegrass more than 10 years ago. He now  helps newcomers get seed on their field by contracting the purchase and application of seed by plane. This year, his company arranged for more than 100,000 acres of cover crop seed to fields owned by more than 400 growers.

Here is a quick reference guide to questions about application by plane.OLYMPUS DIGITAL CAMERAScott said that the cost is comparable to broadcasting seed with high clearance equipment or by drilling after harvest. The advantage of aerial application is that you fly it on before harvest, rather than afterwards. That gives you at least an additional month for the cover crop to establish.

The proper time to apply seed depends on a few things – crop maturity is the most important. Condition of the soil and the amount of rainfall are the others.

For more information on aerial seeding, check out information on our website, here. You can also watch a video on the subject, by clicking here.

Or, you can also download a management brochure that explains elements of the process.

In the end, knowing someone who applies cover crops each year is a good resource for getting answers that will pertain to your farm.

How to Plan for Annual Ryegrass Cover Crop Application

At this point, with corn and soybeans growing to maturity, adding a cover crop this fall can be done in two basic ways: broadcast the seed or drill it.

Broadcasting cover crop seed takes place while the major cash crop is still in the field, towards the end of the season.

    • Aerial seeding is perhaps the most efficient. Seed is delivered to a nearby airfield and loaded in a plane equipped for dispersing a variety of seed types into standing corn or beans.
    • High clearance equipment is outfitted with seed spreaders on long booms. Van Tilberg 2011 Hi-Boy Seeder2

 

The challenges in broadcast application often depend on the equipment. For example, you would need to research your area for an experienced pilot with the proper adjustable seeding set up. Likewise with high clearance equipment: while do-it-yourselfers retrofit their equipment for multipurposes, others find the solution in renting equipment or contracting the application of cover crop seed.

The edge that high clearance equipment has over aerial is twofold: precision and certainty. Whereas planes can be grounded because of weather, rolling equipment has few restrictions in that area. Likewise, aerial application can sometimes create voids in coverage due to seed drift, utility infrastructure and property lines. High clearance equipment, on the other hand, can deliver seed reliably and consistently to every corner of your field.

Drilling Cover Crop Seed used to be the standard in cover crop planting but has become less popular because of one basic reason. The timing for drilling is a problem for many, given the uncertainty with weather after harvest, when drilling is done. Cover crops need passable fields and a month or more of good weather to establish. Broadcasting usually removes that barrier because is is done before harvest takes place.

Annual Ryegrass Seed Sources

Annual ryegrass is a tool for improving soil health and increasing crop yield. In fact, annual ryegrass is like the durable Leatherman tool – just one application to fix a lot of problems.

  • Annual ryegrass puts an end to erosion and the loss of precious topsoil through your tile system and into the nearby waterways. In doing so, you are improving water quality and air quality at the same time.
  • The cover crop has deep roots that break up compaction, accessing nutrients and moisture in deeper soil. During dry years, this helps keep corn from shriveling up in the heat, creating drought resistant plants.
  • Using annual ryegrass also boosts organic matter by providing lots of decaying roots in a more friable soil. More food for the critters that inhabit healthy soil.
  • Among other attributes, annual ryegrass also sequesters nitrogen available in the soil, helping conserve it for use when the corn needs it in the spring, after the ryegrass has been terminated. This saves you money on the amount of nitrogen you need to add during the year.

But like every tool purchase, the buyer must beware. Just as there are Leatherman copies that are cheaply made and don’t last long, annual ryegrass also comes in varieties that are better designed for the tough work of Midwest cover cropping systems.

Take a look at the list of growers and suppliers at this link.ARG Chris B 45 days 10-15 to 12-30-2005 Do some research and, if you have questions, call those who grow and sell annual ryegrass seed. Many of them have invested countless hours and considerable resources in developing varieties of annual ryegrass that are hardy over the winter. That helps to keep something growing year round and prevents wind and water erosion.

Interseeding Annual Ryegrass into Corn

The increasingly popular practice of interseeding annual ryegrass and other cover crops into spring corn continues to receive attention. Why?

  • In the Northern Corn Belt, growers find efficiency to seed cover crops in the spring, rather than the fall, when the window of opportunity for planting is very slim – between harvest and onset of winter.
  • The annual ryegrass gets established in young corn, but goes nearly dormant when the corn foliage creates too much shadow for more cover crop growth beneath it.
  • Interseeding annual ryegrass does not compete with the corn for nutrients or moisture, given that it goes nearly dormant.
  • Once the harvest is complete in the fall, the annual ryegrass picks up where it left off in the spring. The fact that the cover crop is already well established increases the chances it will survive the winter weather.

It’s important to interseed the cover crop into corn that is about knee high. Dan Towery, an expert in interseeding, says that you want to let the corn get at least to V4 stage before planting the ryegrass. Otherwise it might compete with the corn for sunlight.

Annual Ryegrass and other Cover Crops – New Tips on Termination

Admittedly, this is late for the 2017 burndown season. And yet, it’s important to share while it’s topical…managing cover crops is a “growing” interest and we’ll keep an eye on posting an update early next year.

Mike Plumer is the key driver for this article, published a couple months ago by No-Till Farmer magazine. It was taken largely from a seminar Mike did at the National No-Till Conference in St. Louis, earlier in the year. Check out the whole article. It has great tips about managing burndown when the cover crop includes annual ryegrass in a “cocktail mix”. It also looks at the issue of annual ryegrass varieties, and how important it is to know the source of the seed. Different varieties emerge from winter dormancy, for example, which provides problems when trying to kill it in a timely fashion.

Finally, Mike’s discussion covers the subject of killing annual ryegrass once it has reached the “joint” stage or beyond, when control with generic glyphosate will not be enough. Click here to see the entire article.

Increase Your ROI 266% with Cover Crops

Some say that in a down economy, planting annual ryegrass or another cover crop is too expensive. The managing editor of No Till Farming magazine just published an article that shows otherwise.

Based on data from Ken Rulon, who farms more than 3000 acres in Arcadia, Indiana, you can’t afford not to plant cover crops. Not only  does it protect and build healthy soil, prevent erosion, reduce compaction, increase infiltration of rain and snow melt, boost organic matter and microbial activity….it also boosts profits!

Read the article here, by managing editor Laura Barrera, posted earlier this month.

Annual Ryegrass – Now What?

Ok, so now the annual ryegrass is killed. It’s residue will soon become worm food. The decaying roots will become added food for a rich soil biology. The channels left by the decayed roots will create more friability in the soil…crumbly, pliable, spacious. Moreover, new corn and soybean roots will be able to find their way deeper into the soil profile, where added moisture and nutrients can build a more productive crop this year.

Some who are now contemplating corn planing activity may wish to consider adding a next round of annual ryegrass within a short time thereafter. For years now, producers have been having success with “interseeding” annual ryegrass into their corn, when it is less than knee high (V4- V5 stage).

We will cover this subject more in the coming weeks, but for now you could take a look at the following publications, each covering aspects of the reasons, the methods and the benefits of planting a cover crop in the spring.

Glyphosate and Monsanto Clear The Hurdle

An alternative health blogger known as Food Babe has been going toe to toe with Monsanto for years, trying to get traction with consumers on the dangers of glyphosate…Monsanto’s RoundUp.

She has postulated that glyphosate, even in minute traces per billion, causes cancer. But in a recent rebuttal from Snopes.com (an independent, myth-busting organization made up mainly of scientific journalists), they report that the scare tactics leveled by Food Babe are “FALSE”.

RoundUp logo

The federal EPA agency began looking at glyphosate in 1985, and by 1993 concluded it is carcinogenic. They talked about the herbicide’s ability to become waterborne and thus get into drinking water, as well as foods that live in soil exposed to glyphosate.

Since then, it was shown that studies linking cancer to glyphosate relied on concentrations of the chemical that were way out of proportion with amounts that are used in agricultural applications. Recent tests that show potentially adverse effects at lower exposures are also suspect, as peer review has raised questions about scientific methods and data validity.

In March of 2015, the World Health Organization’s International Agency for Research on Cancer said that glyphosate “may have some carcinogenic potential” but, the consensus among the world’s regulatory agencies, according to the Snopes.com article, is that glyphosate “is safe for consumption and non-carcinogenic at environmentally relevant levels.”

Consequently, the World Health Organization concluded: “Glyphosate is unlikely to pose a carcinogenic risk to humans from exposure through the diet.”
