Green under White – The Ideal Winter Color Scheme involves Cover Crops

As winter approaches, the fields now stripped of corn and beans ought to have a cover of green before the snow flies.

First, and foremost, if winter snow comes late or not enough, your soil can be stripped from your property, and you can expect to lose both fertility and productivity as a result. Wind, rain, melt and freeze and run off can be devastating.

A cover crop provides a blanket of protection from the ravages of winter. Annual ryegrass doubles its benefit by protecting the surface while restructuring the soil profile below. It has a massive root system that adds organic matter to the soil. Moreover, it sends roots deep into the soil to 6 feet, through compacted layers, and provides channels for next year’s corn to follow.

With a cover crop in place, even without snow, the greenery will protect the soil from an infestation of annual weeds over the winter, as well as prevent erosion next spring. When you get rid of the cover crop, with glyphosate, the residual biomass left by the annual ryegrass or other cover crop will  continue to decay and feed the corn or beans the stored nitrogen in the residue. That helps to reduce the amount of money you’ll have to spend sidedressing your crop with extra nitrogen in June.

Here’s a link to a number of helpful tips for starting and  managing annual ryegrass as a cover crop. Please contact us if you have questions.

 

Annual Ryegrass in Cover Crop News

Annual ryegrass has been part of a revolution in American agriculture for the past 25 years. Farmers found that no-till is kinder to the soil and that cover crops make soil richer and more productive.

In the past two decades, innovative farmers, research agronomists and Oregon seed growers have worked to improve the ryegrass seed so that it is more reliable, easier to grow and easier to manage. New varieties developed in Oregon now withstand tough winters as well as drought conditions. And, as you’ll see in these attached articles, the innovation continues to thrive.

The Capital Press recently reported about “interseeding” annual ryegrass into spring corn. Click here to read what they’ve discovered.

Click here to look at how to integrate annual ryegrass into a forage operation, seeding the cover crop while applying nitrogen-rich manure.

And for those new to planting annual ryegrass as a cover crop, take a look at this site, brought to you by the Oregon Annual Ryegrass state commission, run by those who grow and sell the seed that is helping to transform farm soil in the Midwest, New England and the Mid-Atlantic states, as well as farms in southern Canadian provinces.

Annual Ryegrass – The Best Defense is a Good Offense

Ok, so the use of this cliche, “the best defense is a good offense” won’t stand up in today’s rough and tumble world of sports. Imagine the Crimson Tide coach Nick Saban or Clemson’s Dabo Swinney trying that strategy in the BCS Championship Bowl!

But, in agriculture, a good defense kind of creates its own offense. Take cover crops, for example, and annual ryegrass specifically.

  • Planting ryegrass in the fall gives the rich topsoil a chance to relax…no worries of some offensive wind and rushing water eroding it away.
  • No worries about compacted soil continuing to starve corn roots opportunity to access deeper nutrient-rich soil beneath the compacted layer.
  • The residue left over when the cover crop is eliminated in the spring (particularly true with annual ryegrass) is food both for the active soil biology, but also feeds the corn next year, because it soaks up excess nitrogen in the soil and gives it back when corn needs it most, next June.
  • The decaying root structure of annual ryegrass also plays an important role in building organic matter in the soil. It feeds the microbes and insects, plus it leaves channels where corn roots can grow deeper the following year
  • AnnuaL ryegrass roots also discourage the overpopulation of soybean cyst nematodes which damage that crop

As the country, and the world continue to grapple with the impact of violent weather, cover crops provide some defense from soil degradation, and contribute to storing more carbon dioxide in the soil instead of releasing it into the atmosphere.

The best of all worlds, cover crops increase farm productivity and profits. And there’ll be no argument about creating a profit while you’re also contributing to the health of our soil, air and water resources.

 

 

Planting Annual Ryegrass This Fall?

For those already employing annual ryegrass in the mix of your cover crops, this information will be redundant. For those new to cover crops, here are a couple of free publications to guide your first efforts.

1. The Benefits of Annual Ryegrass.

2. Management Guide for Planting and Managing Annual Ryegrass

3. Cover Crops for “Prevented Acres”. This is another in a series of posts about why cover crops make sense. It is from the Midwest Cover Crops Council, a valuable resource for good, current information about cover crops and soil biology. The first paragraph from that publication is pasted below:

The Midwest Cover Crops Council (MCCC) recommends the use of cover crops for prevented plant acres when feasible for several reasons. Cover crops can be a good way to take advantage of an otherwise unfortunate situation. A full season cover crop is a great opportunity to improve soil health and function. Cover crops can help to reduce soil erosion and compaction, capture nutrients, fix nitrogen, suppress weeds, moderate soil moisture, and build soil health. Benefits accomplished with these cover crops will put farmers at an advantage for the following cash crop and for years to come. A full season legume cover crop can provide considerable nitrogen for next season’s corn crop. This is also a good opportunity to capitalize on the benefits of a diverse cover crop mix. Mixing species is a good way to compound the benefits from multiple species.

The Glyphosate Issue Continues to Heat Up

It was generally thought that glyphosate was safe for use around humans and animals. Scientists generally agreed that it was not carcinogenic, largely because the molecule is not soluble in fat and thus cannot be stored.

Nonetheless, several juries have awarded tens of millions of dollars in damages to plaintiffs who claimed Roundup caused their cancer (non-Hodgkin lymphoma). They based their case on a World Health Organization (WHO) study.

Other recent studies have found indications that long term exposure to application and use of glyphosate (perhaps in combination with other agents found in Roundup, Touchdown, or other proprietary brands of herbicides) could provide a weak link to a type of leukemia, although another study countered an earlier finding that glyphosate has a weak link to lymphoma (the WHO study.)

At issue, among other things, is whether it is the glyphosate itself, or glyphosate in combination with other active  (non-toxic) chemicals that creates toxicity. A recent article in The Scientist magazine sheds considerable light on the subject, although conclusions are still scarce.  Vanessa Fitsanakis, an 8th generation farmer herself, as well as a neurotoxicologist at Northeast Ohio Medical University, has met and discussed the matter extensively with scientists who defend the safety of glyphosate. Here’s a quote from the article: “Fitsanakis says that while presenting her work publicly, scientists from Monsanto or Syngenta will occasionally show up and politely challenge her research. ‘The scientists that I have spoken to from Monsanto and Syngenta are very convinced that the glyphosate by itself is nontoxic. I agree with them on that. Where I disagree . . . is that you can have an active ingredient that is nontoxic, but that does not mean that the commercial formulation is also nontoxic.’”

She goes on to say that exposure to glyphosate-based compounds may not cause diseases including cancer or Parkinson’s. But, she added, “They may be one of many risk factors that predispose people to developing sporadic forms of Parkinson’s disease in later life. And when that person with [a] genetic risk factor encounters something in the environment, like a pesticide that inhibits mitochondria, then those things together [can start] a neurodegenerative process.”

The public pressure may eventually mean a switch to other forms of weed control. Here’s an article, from North Carolina State Extension, that lists some other products – not as inexpensive nor always as effective as Roundup – but ones that may be waiting for use if and when Roundup and other glyphosate products become more difficult or illegal to apply.

Once The Floods Recede!

Geez, Louise! Another crappy winter leading into a way too damn damp Spring!

When the water recedes, many conventional tillers will be faced with another plague: erosion.

All the damage – washouts, drain tiles plugged, and the value of land washing on down the Mississippi!

In addition to damage to homes, barns, roads and bridges (and the extra cost to import and export product via detours!), farmers have to deal with the prospect of a late spring planting.

Perhaps those who have practiced no-till and cover crops will sigh a bit of relief, if the soil is still on their property when the flood waters drop again. The sight of green grass or legume popping up above the leftover silt and muck will be like a day of sun. Cover crops on the field can be like money in the bank, and erosion protection is just the beginning. Here’s more info on planting annual ryegrass as a cover crop in the spring, if you want to start a new tradition on your land.

Click here for a free booklet on the management of annual ryegrass as a cover crop.

In the next month, those with cover crops will be “managing” their annual ryegrass. Managing, in this sense, means killing it with some form of glyphosate. It’s very important for this step to be done right; if it’s not, it can become a weed and a very robust one at that.

But, take heart, in the 20 plus years of our working with farmers throughout the Midwest, in New England, in the Upper and western Midwest, and in the southern-central provinces of Canada, paying attention to the details of spring cover crop management pays dividends immediately. The residual nitrogen becomes food for the young corn plants, for example. And the rotting annual ryegrass roots make room for corn roots to grow deeper into the soil, adding a layer of protection in the event of a dry summer. Finally, the massive decaying roots of cover crops feed untold gazillions of microbio life forms that contribute to healthier soil.

Best wishes to those of you with water on your property…may the Lord be merciful to you and your families! And when the water drops, consider going down to the Coop and checking out cover crops for protecting your property investment for the next go round. You may decide that trying out a small plot this spring – seeded into knee-high corn (interseeding method) will be this year’s innovation.

 

 

Videos about Successful Annual Ryegrass Planting and Forage Applications

Two of the most popular videos on the Ryegrass Cover crop YouTube site are:

In the first, Mike Plumer and others talk about the basics of no-till with cover crops. Mike, the late (and great granddad of cover crop reintroduction in the Midwest) Illinois agronomist, was instrumental in getting farmers to try cover crops. He was also among the first to begin to quantify the economic and environmental benefits of annual ryegrass.

In the second, Don Ball and Garry Lacefield introduce the basics of developing a successful forage program on your farm. In this segment, they talk about annual ryegrass, because of its ease of development and its superior nutrition. Dr. Ball is a professor emeritus from Auburn University; Dr. Lacefield is a professor emeritus from the University of Kentucky. The pair wrote a very popular book: Southern Forages, now in its 4th printing.

Cattle Ranchers Talk Cover Crops and Forage on Their Feedlots and Farms

Shane and Shawn Tiffany are young, energetic Kansas ranchers, who earned their stripes working for other ranchers before starting their own company in the early 2000s.

Cattle and cover crops

Tiffany Cattle Company is small by comparison, but the men have already begun to attract attention for their integrity, attention to detail and innovation.

Next month, Shawn will be a key presenter at the 2019 National Cover Crop Summit, March 20-21, 2019 — a free-to-attend online event featuring a series of seminars by experts across the cover crop spectrum.

It may come as a surprise to some, but the old fashioned feedlot has changed. Ranchers seek pasture grazing to bring healthier diets, as well as lowering their costs for supplemental feed. Shawn’s company raises 32,000 cattle at a time in two locations west of Topeka. They’ve found that cover crops are both sensible and profitable, they also help to rebuild prairie soil depleted from years of tillage and compaction.

In a search of the internet on the subject of cattle and cover crops, there is a surprising diversity in usage throughout the country. Here’s a story from a 1,100 acre ranch/farm in South Dakota, where Jared Namken raises Angus beef. He says rotational grazing allows him to use the entire acreage most of the year, even with heavy snow cover. He says the cattle will dig through the snow to get to the tasty vegetation.

Nancy Peterson and her husband graze cattle on about 4,000 acres of native grasslands in Nebraska, and  farm 2,300 acres. They use little to no irrigation and the area is dry; annual precipitation is less than 16 inches.

Nitrogen and Carbon – Two More Benefits of Annual Ryegrass

In the last blog post, we addressed the myth of annual ryegrass being hard to manage. Follow good control procedures and it is not an issue whatsoever.

Two other assets of annual ryegrass: it creates a savings in expenditures for nitrogen during the season, and it adds considerably to the organic matter in your soil, thus boosts your carbon uptake in the soil as well.

soil pit2

First thing: nitrogen is a key to production. In years past, when cultivation was more popular, nitrogen was increasingly important and expensive. Now, with annual ryegrass as a cover crop, you can actually plan on reducing your nitrogen input. Why? Because annual ryegrass sequesters available nitrogen in the soil during it’s growth. Then, when it’s terminated in the spring, the residue gives up the stored nitrogen, often just in time for the new crop of corn. In many cases, having annual ryegrass decaying in the field means reducing or eliminating the nitrogen boost in June.

Secondly, as the annual ryegrass roots decay (after the cover crop is terminated in early spring), the result is more organic matter, which means more carbon sequestered in the soil, plus more food for a health soil biology.

Finally, when the roots decay, it leaves the earth more pliable, easier for rain to infiltrate, and easier for corn roots to follow. Because annual ryegrass roots grow to depths of five feet and more, it allows corn roots to access that same depth, beyond compaction and into more nutrients like P and K.

It’s amazing that cover cropping, despite it’s proven benefits, is still practiced so infrequently. While it’s great to learn that in some states, 10 percent or more of farmers are using cover crops, it’s discouraging that upwards of 90 percent are still relying on older ways: deep ripping of depleted soils and adding more fertilizer than would be needed if cover crops were utilized.

The Myth of Annual Ryegrass as a Cover Crop

They say, “It’s hard to control annual ryegrass”. As myths go, it’s tame. They used to say that “stepping on a crack would break your grandma’s back.” They used to think that spiders were bad luck.

For 20 years now, farmers in the Midwest have been planting annual ryegrass every year and there hasn’t been one example of it “getting away.” There have even been cases where the management guidelines have been ignored, but a second application of herbicide took care of that mistake.

ARG burndown

Why do myths persist long after their cautionary value has been used up? Maybe two reasons. First, it takes a long time to turn customs around. Humans have a suspicious streak that dates back to when Saber Toothed Tigers were stalking us for food.

As far as annual ryegrass is concerned, you can believe your neighbor or the old fashioned academic…or you can try it yourself and find out that with modern science, you can dispel this old myth. Annual ryegrass is not hard to control. Click here for more info.  2016 ARG as a Cover Crop – 4 page.

Despite all the success of cover crops, despite endless good media and countless field days, the penetration of cover crops is still less than 10 percent of Midwest farm acreage. Why? Because, as hard as a myth is to dispel, it’s even harder to change  habits. And when it comes to tilling the soil, it’s a habit born of generational work in the field and the efforts of corporate chemical companies to continue selling fertilizer.
