CHILLICOTHE – After eight years of research on no-till advantages and disadvantages with cotton crops, Dr. Paul DeLaune is convinced it’s not as much about the tillage as it is about the cover crop and/or rotation.

DeLaune, a Texas A&M AgriLife Research environmental soil scientist in Vernon, said he has compared no-till, strip till and conventional till, as well as cotton with a terminated wheat crop in the Rolling Plains.
“What we’ve seen over eight years is you are really not changing carbon levels,” he said. “But we shouldn’t be looking at one thing only. Even though carbon levels aren’t changing, we’ve dramatically changed some soil physical properties.”
With cotton, DeLaune said there’s not much residue, so there is little change in infiltration rates between no-till and conventional till cotton.
“But we have seen a greater infiltration rate where we have a terminated wheat crop – doubled or tripled our infiltration rates,” he said.
While the U.S. Department of Agriculture Natural Resources Conservation Service program sometimes requires a multispecies cover crop to qualify for cost share programs, depending on the county, DeLaune said he has been experimenting with both single and mixed cover crops since 2011.
The monocultures he has researched include Austrian winter field pea, hairy vetch, crimson clover and wheat, and the mixed species included rye, wheat, hairy vetch, turnips and radishes. Cover crops are planted at lower than full seeding rates, which may differ from information seen in other parts of the country, he said.
DeLaune said everyone knows cover crops aren’t free, as there is cost for the seed and use of soil moisture, but the benefits can potentially outweigh the costs over time.

“We have maintained our cotton yields. We have seen an increase in our soil nitrogen in the upper 6 inches, particularly following legume monospecies. We have seen a visible response to cotton behind those cover crops.”
He said his team measures neutron probes in all of the cover crop research plots every other week and he has compiled four years of moisture graphs.
“Yes cover crops use water,” DeLaune said. “But some people say cover crops make water. What they are talking about is increased infiltration. We pull soil moisture down by timing of cover crop termination in mid to late April, but if we get rains in May and plant in June, we get a much higher infiltration rate and by planting season, we are back to status quo.”
He said he likes to let the wheat form a head and stem before terminating it, adding that may use a little more water, but that’s what makes the residue, which is the key to protecting the soil surface, building root biomass and subsequently infiltration.
The ultimate goal with cover crops is to build soil structure and make it more functional, he said.
“With cotton on cotton, no-till alone is probably not going to cut it,” DeLaune said. “But we’ve done very well with just a wheat cover crop, that’s a $6 or $8 treatment per acre compared to the $20 to $25 per acre with a mix of some of these species.”
But cover crops alone are not the answer, he said.
“If you are doing continuous cotton, some type of cover crop would be good, but I would encourage a crop rotation,” DeLaune said. “I have data that shows a cotton-sorghum rotation can increase carbon more rapidly, increasing carbon levels in four years under the rotation, whereas we haven’t in eight years with cotton on cotton.”

Tumble Windmillgrass
By Tony Dean
Tumble windmillgrass is a short, compact perennial bunch grass that is adapted to almost every corner of Texas. It can grow on almost any soil, but prefers coarse textured soils.
The most obvious characteristic about Tumble windmill is its large seed head sporting 10 to 16 laterally spreading branches, each approximately two to six inches long, arranged in one to three whorls.
When mature, the seed head will break off and be caught up in the wind, making Tumble windmill one of the great wanderers of the plains. It can tumble great distances, spreading itself in the process. This wanderer seems to like parking in your garage on windy days, as well as dancing around windy corners of buildings and any other place the wind decides to carry it.
Tumble windmill can also spread by short stolons. The upper leaves are very short, while the lower leaves are often much longer. The leaves are light green with a purplish seed head that fades to pale reddish at maturity.
Tumble windmillgrass provides poor forage for livestock and wildlife, although most grazers will use the forage in early spring when tender.
Since Tumble windmill can grow in poor soil conditions, it is useful as a component for a prairie grass mix used on disturbed areas. This grass does not usually dominate a pasture but can often be found in smaller amounts. Proper grazing use along with rotational grazing can cause the plant to be replaced with higher successional plants.

Looking for Low-Maintenance Poultry? Geese are Your Answer!
Unless you are a fan of Dickens and Doyle, geese probably aren’t the first thing that comes to mind when you think of poultry. But maybe they should be. And the aim of this article is to get you acquainted with the aristocrat of poultry.
Let’s start with the basics. Geese are domesticated waterfowl. Twelve breeds are recognized by the American Poultry Association, but dozens more are available. Much like ducks, all domestic geese breeds descend from two species. The overwhelming majority of breeds originate from Greylag geese (Anser anser). This species is native to Europe and Central Asia. These are the stockier, heavy geese that feature prominently in German fairy tales as a symbol of wealth and which Victorians loved to consume at Christmas. These geese come in various sizes, colors and dispositions. Here are a few examples: Cotton Patch geese are a small, variably-colored, extremely heat tolerant landrace native to the South. These were raised to consume weeds in cotton fields in the days before commercial herbicides. They are quite rare today and lay a variable number of eggs. American Buff geese are medium-sized, tan colored, very docile geese of uncertain origin. They are excellent meat birds. They are decent layers and wonderful mothers. Toulouse geese are the largest breed at up to thirty pounds. This ancient French breed is dark grey in color. They are bred to become very fat and so must be managed carefully to maintain fertility. They are very gentle, but require somewhat more shelter than other breeds.
A native of parts of China, Mongolia and Russia, the Swan Goose (Anser cygnoides) gave us both the Chinese goose and the African goose. Both have large bulbs on their heads and are similarly colored, but are otherwise very different. African geese are quite large, maturing at around twenty pounds and prized for their meat. These gentle giants are often recommended for beginners. Chinese geese are the egg champions of the goose family. They produce multiple clutches in a year, equaling up to a hundred eggs annually. They are small geese with males weighing about twelve pounds and females ten. They are nervous and the loudest breed, but this makes them suburb as “watch geese” and perhaps the best all-purpose breed.
Now that we are a bit acquainted with various breeds, we can find out just why someone may want to keep geese. Before we go over their benefits, you may be surprised to learn something surprising about geese. Geese are so rarely seen in the United States today that they can seem unusual, even exotic. As such, you may reasonably expect that geese are hard to manage, require expensive feeds and must be waited on hand and foot. The surprise is that geese are actually significantly easier to take care of than chickens. In fact, I would venture to day that geese are the lowest maintenance poultry there are.
Geese are unique among poultry in that the vast majority of their diet is made up of grass. Some meat birds are raised entirely on grass. It may be a good idea to supplement their grass with some chicken feed and scratch grains, but you will find that, when grass is plentiful, they will generally not bother with anything else. Geese are excellent pasture birds. A simple wire pen that can be moved every other day is enough to keep them happy. Unlike chickens, geese do not scratch up a yard and are not nearly as messy as ducks. If moved promptly, the area they occupied will swiftly grow back greener, thanks to all the free fertilizer, which they produce in abundance. Few geese can fly with any proficiency and even then, only when they are young. One wing’s feathers can be easily clipped, if their escape is a concern.
Geese are also almost absurdly hardy. They not only love rain, they seldom if ever go inside. Shade and perhaps a windbreak are their only real needs for shelter. In sub-freezing temperatures, they will scorn a shed and simply sit in the snow. There is a reason that goose down is so valued for comforters. It is extremely good at keeping them warm. The clever little birds know exactly when they need to bend down over their feet to keep them warm and hide their heads under their wings for the same purpose. In the summer, geese require shade and access to water at all times, but are otherwise unbothered. Geese keep their bodies very clean and are, owing to a small oil gland and their meticulous grooming, waterproof. They will soil water almost instantly, so do not worry about keeping it clean, just be sure they have enough. Without water, they may die in the heat and regardless (like ducks) cannot keep their bills and eyes clean, which could cause disease. Provide multiple water tubs to reduce fighting. Geese will dig up the mud around their waterers, so they should be moved each time they are filled. They will appear to be eating the mud, but are actually filtering it in the water through the serration in their bills. This is to find food, as well as small rocks for their gizzards. With a bit of caution, geese will weed a garden for you and clean it up at the end of the season.
Geese need little more from you than water, basic protection from predators and grass. In return, they offer a number of benefits.
In the first place, Geese offer a dark, rich, beef-like meat. Geese are often butchered between twelve and twenty weeks old. At this time, their weight will vary by breed, but as an example, the commonly raised meat breed Pilgrim geese will weigh around thirteen pounds. The carcass weight will be about sixty to seventy percent of the live weight. If one cares to process it, goose fat is highly valued in the culinary world and contains almost no saturated fat. It is comparable to olive oil and may be used in the same applications.
Especially if you have selected the Chinese goose, eggs are another offering of your new favorite poultry. These eggs are roughly the equivalent of three chicken eggs. A fried goose egg, sausage or bacon and a pancake makes a very nice dinner or hearty breakfast. Alternatively, you can incubate and hatch goose eggs quite easily. The goslings are so valuable that it’s a wiser financial move to only consume the first couple of eggs laid in the spring, which are usually infertile. Goose eggs are easily candled without any special equipment. Infertile eggs or those that die early on can be blown out and made into painted or dyed eggs.
If you hate waste, and wish to use all but the “honk,” so to speak, the feet are rich in collagen and highly prized in the rest of the world. The liver of a goose is extremely healthy and famous as foie gras. A more familiar byproduct of butchering is down, which can be made into extremely valuable bedding. Be sure to clean and dry feathers carefully first. If raised by hand and handled very often, geese will be quite friendly to their owners and make loyal pets. Some people will actually hold their geese in their laps and gently pluck the down from their flock.
Lastly, geese are often kept as watch animals. Geese are extremely observant night and day and will loudly complain when they see something unfamiliar anywhere in the vicinity. It takes a very short time to learn the difference between the normal sounds of geese and the sound of their panic. Please know that while they may scare away small predators and they are nearly always too big for hawks, a goose is largely defenseless against most predators. Keeping geese near a livestock guardian dog is a great idea. The extremely intelligent birds will rapidly learn the dogs are a source of safety and will alert the dogs to anything they see as a threat. Geese can usually be kept with other poultry without problems. They will not directly protect their avian brethren, but the others will learn to hide when the more observant geese voice a concern. In mixed flocks, the noble geese stride around the yard, aristocracy among poultry.
Geese are immensely versatile, the most low-maintenance poultry there is and should have a place on any property.

Changing the Way We Handle Hay
Few machines have reshaped livestock operations as much as the round baler. Before its arrival, haymaking was slow, labor-intensive, and limited by the storage and handling of small square bales. The round baler mechanized the process, producing large rolls that could be handled with tractors instead of back-breaking labor. Today, those big bales are a familiar sight across Oklahoma, Texas, and much of the world, stacked along fence lines or dotting pastures.
The modern round baler traces back to the mid-20th century. While early versions of hay-rolling machines appeared in Europe in the 1940s and 1950s, it was a man from Iowa who brought the design into practical use in America. In 1971, Vermeer Corporation, led by Gary Vermeer, introduced the first large round baler that could be mass-produced and widely adopted. His design gathered hay into a chamber, rolled it into a tight cylindrical package, and then wrapped it with twine before ejecting it onto the ground.
This solved a long-standing bottleneck. Small square bales required enormous labor — lifting, stacking, hauling, and feeding by hand. One person with a tractor and round baler could do in hours what once took a crew all day. The new bales were weather-resistant, stored easily outdoors, and reduced spoilage. They also fit well with the larger scale of modern cattle operations.
By the 1980s, other manufacturers such as John Deere, New Holland, and Case IH offered their own models. Improvements included variable chamber sizes, better pickup systems, and stronger tying methods. Round balers quickly became the standard for beef and dairy producers in Oklahoma, Texas, and beyond.
Though models vary, the principle remains the same. The baler picks up cut hay from the windrow and feeds it into a chamber with belts, rollers, or chains. As the hay circulates, it rolls into a tight cylinder. Once the bale reaches the set size — often 4×5 or 5×6 feet, weighing between 800 and 1,200 pounds — the machine stops feeding, and the bale is wrapped for storage.
The result is a dense, weather-resistant package that can be moved with a tractor spear or loader. Unlike small square bales that require dry storage, round bales can be stacked outdoors, especially when wrapped correctly.
The biggest evolution in round baling since its invention has been the way bales are bound. Early machines used only twine, usually sisal or synthetic. Twine is inexpensive and reliable, but it has drawbacks. Wrapping a bale with twine can take up to two minutes, slowing production. Twine also leaves more exposed surface area, allowing moisture to penetrate and spoil hay.
Net wrap was introduced in the 1990s as a solution. Made of high-strength polyethylene, it wraps the bale quickly — usually in 10 to 20 seconds — and covers more surface area. This tighter, more uniform wrap sheds water better and reduces spoilage, especially for bales stored outside. Net-wrapped bales also hold their shape better, making them easier to stack and transport.
Producers must weigh cost against efficiency. Net wrap is more expensive than twine, both in material and in required equipment, but many ranchers find the savings in time and hay quality worth the investment. Twine remains common for operations feeding hay quickly or storing it under cover, while net wrap dominates in large-scale or commercial setups.
In recent years, bale film wrap has also entered the market. Similar to plastic used in silage, film wrap can seal bales almost completely, reducing spoilage even further. While more expensive, it is gaining ground in wet climates and dairies where feed quality is critical.
The round baler is more than a machine — it changed the rhythm of haymaking. Producers can now harvest, bale, and store hundreds of tons of hay with a fraction of the labor once required. In regions like Oklahoma and North Texas, where cattle herds are large and hay is often stored outdoors, round balers became indispensable.
The machine also influenced land use. With the ability to bale quickly and efficiently, ranchers could harvest larger fields and manage forage with precision. It also reduced dependence on hired labor during peak hay season, a major benefit as rural populations declined.
While square balers still have their place — especially for horse hay and small-scale operations — round bales remain the workhorse of modern cattle ranching.
From its introduction in the 1970s to its widespread adoption today, the round baler has proven to be one of the most influential farm inventions of the last century. It solved the labor bottleneck of haymaking, improved storage and feed efficiency, and fit seamlessly into the mechanization of modern agriculture.
Whether wrapped in twine, net, or film, those big round bales are more than just scenery on a country road. They are symbols of an innovation that continues to save time, labor, and feed across ranch country. Like the steel plow, barbed wire, and windmill, the round baler is an invention that permanently changed the way we work the land.
