Winter Cover Crops Absorb Heat

Recent studies about climate change look at “reflectivity” as a factor of our warming atmosphere.For example, pavement is black and thus absorbs more sunlight than it reflects. Cities are thus warmer because of the amount of blacktop. Scientists recommend planting more trees to block sun and cool city heat.

In a similar fashion, a federally-funded study of cover crops has suggested that foliage has the same effect in winter, raising temperatures by as much as five degrees Farenheit over fields with exposed crops, versus those where white snow reflects most of the sun’s energy.

Here’s a link to the study. Their recommendation with winter cover crops is to cut them or graze them before snowfall, so the remaining foliage will not top out above the snow.

Cover crops left over winter in a field stick up above the snow.

Independence Day – for Cover Crops, it’s Inter-dependence Day…every day!

Remember the bumper sticker: “Every day is Earth Day for farmers?”

This Independence Day, think about that bumper sticker. Just because we farm, does it mean we’re in tune with everything Mother Nature brings forth? Does it mean that farming by the book, the way our fathers and grandfathers did, will make a difference for our sons and grandsons? Does Independence Day suggest we’re free, but only in the political sense?

America, Flag, Usa, United, States

When it comes to agriculture, paying attention to interdependence is what makes a good farm great. Cover crops and no-till is a good example.

  • Conventional tillage compacts soil and leaves topsoil free to erode or blow away. Cover crops breaks up compaction and prevents erosion and loss of a farm’s best resource.
  • Mono-cropping strips the soil of important nutrients. Cover crops, especially on no-till acres, builds organic matter that attracts healthy microorganisms, friendly bacteria and earthworms
  • Nitrogen-loving cash crops need added inputs to keep corn thriving. Cover crops sequester or add nitrogen which reduces the need for fertilizer
  • Conventional tillage allows for one harvest a year. With a forage cover crop, you can do all of the above PLUS get a cutting of hay or graze your livestock.

Interdependence means that we can improve our bottom line and increase our farm’s value by working with nature. Working hard comes with the territory. Working smart, in the framework of soil biology, will help everybody up and down the food chain.

Videos – Comparison of Cover Crops courtesy of Clemson, Ohio State

Check out these videos if you want to see a wide variety of cover crop types. Two well known universities – Clemson University and Ohio State did small plot demos on a lot of traditional as well as new entries in the cover crop family. The videos were shot in April and May of 2018.

Annual ryegrasses features prominently, with some new varieties, including “Frostproof”, “Kodiak” and “Winter Hawk”, as well as “LowBoy”. The value of the first of these new varieties might be winter hardiness. In the second instance, interestingly, LowBoy has less top growth but the root structure is similar in mass to taller varieties. this might be of value for farmers not interested in grazing the annual ryegrass,but wanting the cover crop’s deep rooting and other virtues (breaking compaction, nitrogen uptake, erosion and weed control).

Some other cover crops they examine include different varieties of vetch, clover, peas, triticale, and oats.

The value of university research in agriculture is inestimable, because their funding allows new developments for improving industry standards and growth. But aside from that, the students coming through those programs will be among the new leaders in finding ways to increase production while also conserving resources.

A New Kind of Weather, A New Kind of Pioneer

Two hundred tornadoes in two weeks? What next, will we have to have to protect ourselves from frogs falling from the sky?

It has always been a challenge to stay flexible to what Mother Nature throws: a deeper, longer, windier winter without enough snow, for example. Or a winter that starts and stops, with freezes and thaws changing places like partners at a high school prom.

Farmers have been a resilient lot since agriculture began in earnest, more than 10,000 years ago. And though not a new invention, cover crops are another indication that adapting to new challenges is part of the landscape.

Consider how cover cropping, combined with no-till, gives you the edge with a tempestuous season. With annual ryegrass on your fields in the spring, excess amounts of water keep the soil in place. Because the soil is more permeable, water can penetrate more quickly instead of running off and causing erosion.Annual ryegrass grows well in wet conditions, too, so a soggy spring may delay corn planting for a bit but the cover crop will protect what’s there.

Cover crops like annual  ryegrass also increase greatly the potential for corn to grow deeper into the soil. Annual ryegrass busts up compaction, down to six feet! That means in dry years, corn can send roots deeper for moisture and important nutrients, like P and K, withstanding drought conditions for much longer. Because annual ryegrass sequesters available N, you don’t have to side dress as much as you did in the old days.

Then, because cover crops improve organic matter and carbon in the soil, there is a healthier microorganism population, the soil is more crumbly and rich with life. The crops are healthier, and the harvest is more robust.

So, yes, we can still bemoan Mother Nature for throwing us curve after curve. We can complain that the co-op prices are too high, commodity prices too low, and the bank is tightening the screws. But with tenacity, and a friend like annual ryegrass, you may again be able to say you rode it out, weathered the storm, and came out on the right side of the ledger.

Is “Good Enough” Good Enough Anymore?

When has “good enough” been your measure for anything? Raising your kids? No! Nothing’s good enough for them, right?

Electing honest leaders? Imagine where America would be if we decided that mediocre was all we could expect from those we elected? The Founding Fathers would be turning in their graves!

And how about farming? Has “good enough” ever satisfied you as the decider-in-chief? How would those who buy your crops react if your corn, beans and livestock were marginal? You’d be outta business pretty quick.

Corn emerging through ARG residue

That’s why putting cover crops on yoyur acreage makes perfect sense. For years, those who believed in deep tillage thought they were doing the best they could…rip deeper, add more fertilizer. But now we understand the complex way in which soil health is maintained, so the old ways are not good enough anymore!

It turns out that taking care of your soil, like being a watchful and loving parent, yields amazing results. With no-till and cover crops like annual ryegrass, micro-nutrients, bacteria, and carbon quickly come back to your anemic soil, even after decades of mediocre care.

  • Annual ryegrass breaks up compaction, so your crops can reach more moisture and nutrients below.
  • Annual ryegrass sequesters nitrogen, so you can save on fertilizer while preventing spring erosion.
  • Deep rooting annual ryegrass allows corn roots to grow much deeper into the soil – up to 6 feet deep – which gives your cash crop resiliency against dry summers.
  • You can graze livestock on cover crops…maybe even twice in one year…which saves you money on feed, while below the surface, the cover crop is delivering organic matter in great quantities, food for earthworms and other micro-flora and fauna.

Finally, in one of the classic “win-win” scenarios, cover crops have proven to boost production. Given how much benefit the soil gets (not to mention the benefits to the watershed and the air!), it’s not hard to imagine that it would benefit the health of the crop too.

So if “good enough” is continuing to be your standard operating procedure, you’re missing out on an opportunity to succeed in a way that benefits your wallet while adding value to your property. And if you’re the one to lead the way in your community, how great is would it be to be acknowledged as a leader, a trend setter, while contributing to your community’s health.

When good enough isn’t good enough, you’ll be raising the bar for the whole darn town, setting a standard for health and prosperity. What a legacy, right? Being known for going the extra mile to benefit others as well as yourself?

 

Earth Day – A Tribute to No Till and Cover Crops

Perhaps the hoopla about climate change and global warming is yielding some new converts to no-till and cover cropping.

Not to say whether “man caused” or “cyclical trends” is the primary factor for the increased severe weather in the Midwest. Suffice it to say that, no-till and cover crops can help mitigate some of the weather-related damage.

Tillage is almost as old as human agriculture, a sure way to reduce weeds in cropland. No-till is also an ancient practice, but in the US, it wasn’t until the 1970s that it began to make headway in modern farming.

Cover crops are also historically significant. In ancient Rome and throughout Asia, farmers have long known the value of adding natural nutrients back into crop rotations to sustain soil fertility and health. Use of a type of Vetch, for example, rejuvenated rice paddies and, just before a new planting, the vetch was removed and composted. Leaving it for too long, they learned, could rob the soil of nitrogen.

In the US, George Washington was an advocate for cover crops and extended rotations. Just before he took office as our first president, he wrote a letter about his quest for barley seed, as well as clover to be used as a cover crop.

In more recent times, the Oregon Ryegrass Commission developed a partnership with university agronomists and farmers to launch what has become a very profitable addition to agriculture. Profitable, yes, for those growing and selling of seed. But even more profitable for those planting cover crops, because of its immense value at reducing costs while increasing soil health, diversity and productivity.

Whether it’s used primarily to reduce compacted soil, to reduce erosion, reduce weeds or reduce the amount of extra nitrogen in the field, cover crops like annual ryegrass are proving their value. Whether you’re looking to increase organic matter, deepen the soil profile accessed by corn plants, improve water infiltration into the soil or increase crop yields, cover crops deliver on those promises.

So as Earth Day rolls on by, give a shout out to those innovators who continue to advocate for farming practices that save the air, the water and the earth…while adding to your bottom line.

 

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.

Getting back to the 2019 National Cover Crop Summit, March 20-21, 2019 , here are some of the other notable presenters:

  • Steve Groff, Common mindsets for cover croppers, cover crop consultant, Pennsylvania
  • Tom Cotter, Interseeding cover crops for grazing benefits, f

  • Paul DeLaune, Extending cover crop benefits in continuous wheat and cotton rotations, Texas A&M Univ.
  • Rob Myers, How cover crops impact farm profits, SARE/USDA
  • Erin Silva, Rolling cover crops in no-till systems, Univ. of Wisconsin Organic Ag.
  • Damon Reabe, Seeding cover crops aerially, even in spring, Cover crop applicator
  • Chris Teachout, Alternative row spacing and biomass-building with cover crops, farmer, Iowa

Erosion Control – Listen to Cover Crop Innovator Steve Groff

It’s hard to believe that no-till and cover crops are still a strange concept to farmers, even after all the positive news there has been about it. Even after 30 years of increased popularity, less than 10 percent of Midwest farmers are active users of this revolutionary practice.

Steve Groff, a Pennsylvania farmer since the 1970s, said he first looked into no-till in the early 1980s, trying to slow down the erosion on his acreage. He said in a recent interview  that the practice did slow down erosion, especially after he began using cover crops.After three years,  he also noticed that the soil began to “mellow out,” meaning the infiltration of rain water increased, the organic matter was more evident and the microbiology in the soil improved.

In 1995, when cover crops first began to emerge, thanks in part to the Oregon ryegrass seed growers (and Mike Plumer at the Univ. of Illinois Extension), Groff began working with Dr. Ray Weil, a Univ. of Maryland professor of agriculture and natural resources. Groff and Weil partnered on research on cover crops. In the fourth year, Pennsylvania experienced a drought and Groff noticed that corn yield on acres planted in cover crops got 28 bushels more than adjacent fields with no cover crops. That was what convinced him…the boost in yield because of healthier soil.

“You couldn’t pay me to NOT plant cover crops,” Groff said.

But, to go back to erosion for a moment. In the Regenerative Agriculture Podcast, with John Kempf,  the host described just how devastating erosion is for healthy crops. NRCS calculated that, on average, farmland in Iowa loses two pounds of topsoil every year for every pound of grain harvested!

Put another way, Groff said, every 1/4 pound hamburger represents four pounds of of topsoil lost to erosion!

Dust storms in Midwest, in addition to stripping topsoil from productive agricultural acreage, also causes fatalities due to poor visibility on roads.

Later in the podcast, Groff said that when he thinks about soil health, it’s not so much about a problem with erosion but a problem with infiltration. In other words, cover crops dramatically increase the soil’s ability to absorb water instead of it washing off the surface and removing topsoil with it.

He also said that soil health is not so much an issue with fertility as with microbial health. He said that if you have something growing in the field all year, with cover crops in the wintertime, the bacterial and microorganisms that rely on stable soil (untilled) with lots of organic matter. So, if the microbial health is there, the soil quality will be there as well.

Ryegrass, Good for a Climate Goin’ Through Some Changes

Science tends to win out over guesswork. Few would disavow centuries of medical experience in favor of hocus-pocus and suspicions. Similarly, those with decades of working the soil tend to heed the sciences pertinent to agriculture, rather than winging it based on something you heard from your brother-in-law.

So, whether the science of climate change is spot on, there’s little question that weather continues to be a major factor in growing healthy crops. Storms may be getting stronger, so it’s crucial to protect your most valued asset: the soil.

Corn Plant on Field

Annual ryegrass protects the soil from erosion throughout the year, because the soil is never fully exposed to the wind and heavy rain. Infiltration of water into the soil is improved, thus increasing the reservoir of moisture for later months. And when flooding does occur, cover crops like annual ryegrass will slow it down, and keep the event from washing out field tiles. Cover crops keep the moisture in the watershed, instead of it washing downstream, carrying  precious nutrients.

No-till and cover crops also provide soil integrity, allowing the roots and other organic matter to create an environment of stable health. As a living entity, the soil environment stays in place better when bad weather occurs if you’ve got it covered with a cover  crop..

When it turns dry, cover crops tend to reduce oxidation of the soil, and to provide a longer period before the soil dries out. Annual ryegrass roots being far deeper than other cover crops, it’s a safe bet that corn will flourish if annual ryegrass has been in the field for even five years as a cover crop.

Genetic engineering has played a significant role in crop durability and production. Coupled with no-till and cover cropping, agriculture in the Midwest is better equipped to withstand the changes brought on by climate variations, whether for the short term or permanently.

National Effort to Expand Use of Cover Crops

The Foundation for Food and Agriculture Research launched a national effort to expand use of cover crops. Called the Healthy Soils, Thriving Farms initiative, the group includes the USDA as well. It is a collaborative, multi-partner research effort to improve soil health in the United States. It continues the effort to encourage adoption of cover crops as well as develop new cover crop varieties with enhanced soil health-promoting traits.

The research expands into states not commonly practicing cover cropping methods, like

  • Maryland,
  • North Carolina,
  • Oklahoma,
  • Nebraska and M
  • issouri. Ideally, the research will begin with

cover crops with the greatest potential to improve soil health in a broad geographic context.  Annual ryegrass, small grains, annual legumes and brassicas will be used to start.

As has been demonstrated throughout the Midwest, northeastern US and southern provinces in Canada, cover crops are valuable for these reasons:

  • Improve soil health.
  • Mitigate erosion.
  • Increase crop yields.
  • Enhance water use efficiency.
