Meet Bluestem Farms.

Posted on April 30, 2015 by laurab08

While in past years the Amelia County operation has been home to a herd of Kiko goats and several outstanding performance-tested bucks, Robie and Angie Robinson and their children have spent the past twelve years shifting their focus towards growing and improving their sheep and cattle herds.

Like many farmers, the Robinsons raise a little bit of everything to sustain their family—chickens, meat from their livestock, and a large garden with everything from asparagus to onions. While they also finish, harvest, and sell some meat to a group of local customers, they market most of their animals including their weaned feeder calves conventionally on the livestock market as most local cattlemen do.

However, their cowherd is rather unique—it consists primarily of Devons, not to be confused with Milking Devons which are also rare in this area. Devons are a hardy, red-coated breed from England and they come in the relatively small to moderate frame size that Robie maintains as a goal for his breeding program. He pays particular attention to the genetics of his herd through bull selection and culling. Because he relies on a forage-based production system, he wants cows that are programmed to efficiently convert grass to milk for their calves and he wants beef calves that grow well on a grass-based diet. Like the many other cow-calf operations in the region, most of the calves will be weaned and sold as “feeder calves” to buyers who will take them elsewhere for more growth and “finishing” prior to harvest. However, since Robie finishes some of his own animals on grass and harvests them for customers, he pays particular attention to carcass quality traits when he selects bulls for his program.

While driving past Bluestem, it is hard to miss the Robinsons’ herd of sheep. After all, relatively few people in Southside Virginia still raise sizable herds of sheep. Robie made the transition after he noticed more desirable marketing opportunities for his sheep than for his goats, and today he raises them primarily for the Easter market, a prime window for selling lambs.

Like his beef herd, Robie’s sheep are also unique. His ewes are mostly Katahdins, a breed of hair sheep that requires no shearing because the animals shed their coats in the spring. Katahdins have been recognized for their success on grass, high fertility, and adaptability to a variety of conditions, making them an excellent fit for the Robinsons and their forage-based grazing management program. While some breeds traditionally lamb indoors and require special care to ensure good mothering and survival immediately after lambing, Katahdins are well-suited for “pasture lambing,” and Robie notes that he rarely has to provide any assistance to his ewes at lambing time.

As with his cattle, he uses careful culling as a tool to reach towards his goals for herd genetics. Ewes that fail to produce and raise twins are generally removed in favor of ewes who are predisposed to prolific lambing and good mothering traits. He also culls in favor of sound feet and easy shedding. The Robinsons have managed to import desirable genetics into the herd via purchasing performance-tested rams from University of Maryland and Virginia Tech.

Sheep are notorious for wearing out pastures and cattle can be equally hard on forages if producers do not manage their grazing systems carefully. Since the Robinsons rely on grass to do all the legwork for growth and milk production for both species, they have prioritized pasture care on the operation to meet their needs. Robie has a few goats in every field with the sheep because they tend to graze onions and some of the other hard-to-control broadleaf weeds that sheep may pass over.

While he used to apply conventional fertilizer regularly, Robie’s philosophy on fertility management has shifted over the years and today he prefers to rely mostly on chicken litter when it is needed. However, when using litter, he notes that he must take care not to overload the field with certain nutrients, especially phosphorous. Like all farmers, he occasionally needs to lime his fields to adjust the soil pH. He manages his grazing strategy according to conditions—in some cases, he chooses to “flash graze” his fields to manage bouts of rapid spring top growth.

A visit to the Robinson farm yields a blue-green view of plentiful orchardgrass throughout the sheep pastures. Orchardgrass is a high-quality, highly-palatable species that also makes excellent hay. However, if it is mowed or grazed repeatedly close to the ground, it does not tend to persist. Robie uses a haybine instead of a disc mower when he cuts his fields for hay, and over the years he has seen that his orchardgrass has thrived and persisted for much longer than expected.

Mixed with the orchardgrass is some hairy vetch and plentiful clover, much of which turned up in the pasture on its own. Robie planted some stands of hybrid Bermuda grass experimentally in past years and those stands remain productive each summer. He has also planted Red River and Quick and Big crabgrass, both of which make excellent forage and seem to reseed themselves readily.

Bluestem has changed considerably over the past twelve years, as have Robie and Angie’s production strategies. Robie used to engage in row crop production before favoring livestock—the farm as it stands today was started with twelve registered angus cattle. Around the same time that Robie gained an interest in Devons and Katahdins, he also shifted his paradigm surrounding farm management in favor of grass ecology and robust soil microorganisms. “I was a cattleman, then I was a grass farmer, now I’m a mycologist,” he jokes. Nonetheless, his goals for building healthy land and soil are serious, and the proof is in the results—healthy lambs and calves, green pastures, and happy customers.

Meet Whit and Jennifer Morris.

Posted on March 20, 2015 by laurab08

Their farm business took shape in 2003 when they bought land in Blackstone to support their cowherd. Around this time, Jennifer was an Extension agent in Nottoway and Whit also had a career in agriculture. As the business grew, Jennifer made the transition to caring for the farm full-time, and Whit joins her to manage the farm outside of his job.

Today, the family runs a commercial herd comprised mostly of Angus and Gelbvieh crosses. The farm is primarily a cow-calf operation, meaning that Whit and Jennifer breed their cows and heifers each year, raise the nursing calves to weaning age, and sell the calves after weaning time. They choose some of their heifer calves to stay in their breeding herd. They also send some of their animals to annual Virginia Premium Assured Heifer sales and Virginia Quality Assured feeder calf sales in conjunction with the Amelia Area Cattlemen, a local producer group.

While the calves born on the Morris farm may eventually go on to a feedlot for the last few months before harvest, these calves and their dams spend a considerable portion of their lives out on grass. In fact, the many cattlemen who run cow-calf operations in Virginia know that the most efficient and economical way to manage cows and their offspring from calving time to weaning time is on pasture—pasture which, Whit and Jennifer have learned firsthand, requires strategic management if it is to meet the demands of lactating cows and large, growing calves.
Cattle producers can feed hay to meet the animals’ forage requirements when grass is not growing in the summer or when it goes dormant in the winter, but the cost of making or buying hay can far exceed the cost of maintaining a good stand of grass. To minimize the number of days that they must feed hay and to maximize the health, efficiency, and productivity of their pastures, Whit and Jennifer have spent the last several years building and improving a controlled grazing system to take full advantage of the tall fescue, clover, Bermuda grass, and other species growing on their land.

Their grazing plan changes throughout the year according to conditions and forage growth habits. In the summer, the cattle follow a “rotational grazing” system. In this system, the pastures are subdivided and animals are given access to one area at a time. Jennifer moves the cattle to a new area when the grass is grazed to a critical height. If cattle stay in one place too long and graze forages too closely, grasses lose nearly all of their leaf area. They then have to expend their root reserves to supply energy for sending out more leafy growth, and they tend to bounce back slowly even when given a rest period. If Jennifer pulls the cattle off of each paddock before the cattle overgraze it, the grasses have enough leaf area left behind to fuel fast regrowth through photosynthesis.

In the cold months, the farm switches to a “strip grazing” system to make use of the tall fescue which was grown in the fall months and saved or “stockpiled” for the winter. Strip grazing offers benefits similar to rotational grazing, but unlike a rotation in which animals are moved from fenced paddock to paddock, strip grazing entails setting up a temporary fenceline and moving the animals’ fenceline further and further down the paddock as the animals consume what is offered to them. Each time Whit and Jennifer move the fence and provide access to a fresh part of the pasture, the animals consume the available forage far more evenly and efficiently than they would if they had simply been turned out continuously on the entire area at once.

In a continuous grazing system, animals access the entire available pasture at all times, and, due to behavior and preferences, end up overgrazing some areas and underutilizing others, resulting in changes to both the health and the quality of the forages. Animals also tend to congregate and loaf in the same areas each day, concentrating nutrients from manure in these areas. To complicate matters, many parts of the pasture can never adequately rest from overgrazing and the stand of grass eventually becomes weak.

Both of the grazing strategies that Whit and Jennifer employ—rotation and strip grazing—have well-documented advantages over continuous grazing including more even nutrient distribution, higher pasture utilization, and more efficient use of available forages. Whit and Jennifer have also seen a significant downsize in hay feeding requirements because their management strategies create highly productive pastures and lengthen the number of days that forage remains available during the winter.

A cattle producer who does not have enough available pasture or who does not use a controlled grazing plan may end up feeding hay to pick up the slack during the summer, in the late fall, and all throughout the winter if the pastures become weak or overgrazed. This can quickly become expensive, and Whit and Jennifer have been grateful that their pasture management plan has brought relief from a portion of their hay costs. “We didn’t feed hay til the snow this year,” Jennifer notes. In a typical year, she also feeds some hay in the fall so that pastures can build some growth and later be used for winter grazing. “We might feed hay around the end of October or first of November while the stockpiled fescue is growing,” she says.

Enacting rotational grazing or strip grazing may sound like plenty of work on its own, but to Jennifer, it beats the labor and fuel associated with making hay. “We cut hay when absolutely necessary, and if we don’t need to cut it, we bush hog the extra to save the nutrients for later,” she says. In the business of raising cattle, “there’s enough work in it already with maintaining fences,” says Jennifer.

A good grazing plan may save on hay, but some people worry that adopting an intensive plan may rack up fencing costs in the short-term, trading away the economic benefits of reducing labor, fuel, and fertilizer for haymaking. However, Jennifer has advice for graziers who wish to adopt a sensible controlled grazing plan for the sake of reaping the long-term benefits. “Keep fencing simple,” she offers. “Use good outside perimeter fencing and cross-fence with a simple single wire—a few T-posts, a few wooden posts, and your wire. The worst that can happen is mostly some calves might get into the next paddock and graze more. It doesn’t have to be built to government specs.”

People who have limited time or who are not yet ready to jump on board with strip grazing can benefit even from simply dividing a pasture in half and rotating cows between halves—many who start this way later choose to subdivide pastures further, including the Morris family. “We went from one paddock to seven in Blackstone using the available water,” Jennifer says in reference to the developments she and Whit made on the farm soon after they purchased it.

What is next for the Morris farm? Whit and Jennifer hope to address some challenges plaguing herds in Southside Virginia including their troubles with fescue toxicosis, a problem caused by a symbiotic organism living in tall fescue grass which can cause physiological stress on cattle. For now, they provide as much shade as possible to relieve some of this stress in the summertime. In the future, Jennifer and Whit also would like to incorporate more clover into their pastures for both its nutritional benefits and its nitrogen-fixing abilities. Frost seeding may be on the agenda when winter comes back around.

For now, the farm is thriving and the care and attention spent on grazing management is paying off. The farm has even recently been used as an educational resource during grazing schools offered by the Virginia Forage and Grassland Council and Virginia Cooperative Extension. The grass may have just begun to green up thanks to a cold, sluggish March, but come spring and summer, the pasture rotation will be in full swing, and the Morris family eagerly awaits the chance to get their cattle back on some good grass. To the animals, who have learned that the grass really is greener on the far side of the polywire, the presence of Whit or Jennifer coming to open the gate to the next field elicits equal excitement.

Meet the Southern Piedmont Agricultural Research and Extension Center.

Posted on September 1, 2014 by laurab08

More commonly abbreviated as “SPAREC” by those familiar with it, this center is one of Virginia Tech’s eleven experiment stations, or “ARECs,” scattered across the state. The stations were each established to perform research and outreach matching the needs of local agricultural industries.

Sorghum and sorghum-sudangrass hybrids are grown at the station for the livestock forage research program.

For the Southern Piedmont region of Virginia, tobacco remains a key agricultural product with deep historical significance, and forage production is a critical factor keeping cattle, goat, sheep, and horse operations in the area profitable. To serve the farmers growing these products, SPAREC, located in Blackstone in Nottoway County, provides support and cutting-edge information to farm producers. The station has also performed work in small fruit, field crop, and specialty crop production.

While many people in the eastern, central, and northern part of Virginia have never seen tobacco and the number of tobacco farms in the state has dwindled, it remains the 10th ranking agricultural commodity produced in the state just behind wheat, generating $109,000,000 in receipts annually. Much of the tobacco research at SPAREC centers on improving crop management, testing new materials and practices in the greenhouse and the field, and evaluating new varieties. However, the tobacco projects honing in on plant pathology, nematode management, plant breeding, conservation tillage, energy efficiency, and precision application technology have broad implications for other agricultural industries.

Dr. Charles Johnson, Dr. David Reed, and Dr. Carol Wilkinson each work in one of the unique tobacco research areas at SPAREC. For most of the trials performed at the station, tobacco plants are started in float trays in greenhouses and transplanted to test plots in the spring. The stage after transplanting is called “lay-by,” followed later by flowering when the plants grow tall. Tobacco plants produce pink flowers, but these are “topped,” or removed, so that the plant utilizes its resources on vegetative production. During ripening later in the summer, lower leaves of “flue-cured” tobacco varieties are harvested first, followed later by upper leaves. The leaves are packed in a curing barn and dried by circulating air. “Burley” and “dark-fired” tobacco varieties are harvested all at once; the stalk is cut at ground level, speared on a stick, and hung in a barn. Most Virginia tobacco grows in the counties along the south of the state, where soil characteristics, industry infrastructure, and growing conditions favor production.

Tobacco grows pink flowers, which are “topped” to promote vegetative growth.

Tobacco remains a primary crop at SPAREC, but forage research is an equally critical program at the station thanks to increased interest from farmers who want to mitigate high livestock production costs by improving forage quality and grazing efficiency. Dr. Chis Teutsch has spent years running trials, compiling variety data, creating forage publications, and speaking at Extension and industry events throughout his years working with legumes, Bermuda grass, crab grass, cool-season grasses, and warm-season annuals like brown mid-rid forage sorghums and sorghum-sudangrass hybrids.

Dr. Chris Teutsch manages a Bermuda grass research trial at the station.

To enhance the depth and breadth of the forage program, SPAREC saw the recent addition of a cattle-handling facility and installation of fencing and water troughs on new pasture ground. With the addition of Ruminant Livestock Specialist Dr. Brian Campbell in 2012, the station brought cattle onto the premises for forage utilization studies, grazing schools, demonstrations, cattle management workshops, and research. In fact, since outreach is an important part of the Extension forage work done at SPAREC, producers have numerous opportunities to come visit the station’s cattle facilities and forage plots including a field day each year in July and the many workshops held at the station throughout the year.

Outreach does not stop with forages. The tobacco specialists also organize a widely-attended annual field day in July and several production meetings for farmers in the winter. Thanks to its central location providing easy access for farmers in several surrounding counties, the station frequently hosts workshops put on by nearby county Extension agents covering topics from beef production to greenhouse management to grain crops.

The station is equipped with wagons to transport visitors during field days.

Farm staff have prepared a corn maze for the 2014 Family and Farm Day on September 13th.

Youth agricultural education has become a priority in recent years. Visitors to the annual SPAREC Family and Farm Day witness the station’s commitment to this task and long-standing partnerships with community organizations and agencies. The end result is dozens of hands-on activity stations for the hundreds of children and adults who attend the event to learn about agriculture. This year’s Family and Farm Day, set for September 13 from 9-2, will teach visiting children about soil health, conservation, farm life, livestock, vegetables, crops, insects, wildlife, safety, and farm equipment. SPAREC also hosts Ag Days for 3rd and 5th grade classes for two weeks each April. The Ag Day programs draw buses of students from public and private schools in each county surrounding the station. They continue to grow in attendance each year thanks to the real-life application and reinforcement of classroom lessons and standards of learning they offer.

Since its formal establishment in 1972, the Southern Piedmont Agricultural Research and Extension Center has been a force for changing, improving, and modernizing agriculture. The end result is a stronger local agricultural economy built by individuals empowered by the knowledge they have gained from the station’s research and outreach.

Meet Mike Henry, pasture manager.

Posted on January 9, 2014 by laurab08

He has worn many hats over the years—Extension agent for Chesterfield County and then Amelia before he retired, cattle producer, and founding member of the regional Amelia Area Cattlemen. He is also one very excellent pasture manager. He spent the last several years improving the pasture on his Amelia farm, adding fencing and water sources as he went. When he first set out, his goal was to sustain enough forage to successfully support a beef cattle herd on a year-round strip-grazing management system.

Pasture land in central Virginia is abundant, hence the number of cows in the region, but not all producers are able to sustain animals year-round on pasture alone. Why? The availability of pasture forage depends on the seasonal growth of the species in the pasture. Because this region is set between the cold northern climate and the warmer South, cool-season and warm-season grasses can both be grown here and many pastures contain a mixture of both.

Mike Henry’s pastures contain a mixture of tall fescue, orchardgrass, clover, and even some ryegrass that emerged in early winter.

Cool-season forages grow most actively in spring and fall when the weather is cool, but go dormant in the summer when little moisture is available. Many producers must resort to feeding hay during this season while they wait for fall pasture regrowth. Tall fescue is the most common cool-season forage in most pastures, but other plants like Kentucky bluegrass, orchardgrass, timothy, and clover are also in this group. Cool-season grasses stop growing during the winter, but can be preserved or “stockpiled” during the cold. Tall fescue is the hands-down best choice for stockpiling, retaining its nutritional value for several months after the growing season even under snow and ice. In order to stockpile a tall-fescue pasture, the manager must remove the animals from the area in the late summer, giving the pasture a chance to recover and initiate heavy fall growth. The animals can return to the well-grown pasture in December or January, resulting in an extended grazing season that heavily cuts the costs associated with feeding hay. Mike Henry practices stockpiling on his pastures, as do many of his peers in this region.

Warm-season forages like Bermuda grass or crabgrass have the opposite growth pattern. Their growth is dominant during the hottest part of the year, but they go dormant at the end of the summer and do not take off again until the spring. As a result, producers with pastures full of warm-season plants must either feed hay during the cool seasons or establish a cool-season pasture in a new area to keep cows fed during the fall, winter, and spring.

Mike Henry’s pastures contain mostly tall fescue, but other elements including crabgrass, orchardgrass, clover, and ryegrass are present and contribute to the diversity of the available forage. The clover mixed with the cool-season grasses is a legume plant, meaning that it contains a high level of protein and supports the needs of young, growing cattle and lactating brood cows. To establish and maintain dense stands of these forages and choke out competing weeds, Mike has stayed on top of mowing, seeding, reseeding, and nutrient management, but the economic benefits have outweighed the costs.

In a “continuous grazing” system, cattle are given access to the entire pasture acreage at once, so they have the option to overgraze forages that are highly palatable, stressing the plants’ root systems. They under-utilize other areas, and they tend to create muddy spots near central hay feeders and water troughs. Finally, they may not distribute their manure very evenly, resulting in both mucky areas with a glut of nutrients and neglected areas that receive very little natural fertilizer. The alternative? Many producers have adopted “rotational grazing,” whereby a pasture is split into a few sections and animals are moved from one section to another every few days or weeks. As a result, each pasture section has an opportunity to rest and build strong roots, resulting in a longer-lasting, more robust stand of forage. Furthermore, the animals consume the existing grasses more evenly and efficiently. Manure is distributed far more uniformly in a rotational system, which aids in desirable nutrient cycling and reduces fertilizer expenses.

Mike Henry practices the more intensive cousin of rotational grazing, known as “strip grazing.” In this management system, cows are given a small strip of pasture at a time and are moved from one strip to the next as frequently as once a day or sometimes even every few hours. The pasture utilization rate increases dramatically when animals are tasked with eating one small area at a time. Mike knows that the key is making sure that the cows always have something to eat, so he will be the first to tell you that strip grazing brings an economic advantage but also a new requirement for labor. Nonetheless, since most cattlemen check their herds frequently, the time it takes to open or close a temporary fence to a pasture strip is negligible and affords an opportunity for the producer to get a close-up look at the cows.

Mike’s pasture setup is conservation-minded. He has excluded his cattle from the dam and waterways on his farm, and on the occasions when he has had to supplement his pasture with an occasional bale of hay, he unrolls and spreads the hay in a new area each time so that the cows do not heavily disturb the soil in one particular location.

As a former Extension agent, Mike understands the value of helping other farmers, so he has had the opportunity to show his system to several beginning cattle producers and even a few experienced ones who wanted to see strip grazing in action. He has also noted one unexpected benefit from all his time spent moving fences and walking the pasture to check on his forages—the heifers he manages have become more docile from close daily exposure to his presence and follow him wherever he goes, making it easy for him to take them wherever he needs them. Add up quiet cattle, a thriving pasture, and annual hay savings to get one content cattleman.
