COLLEGE STATION – There have been considerably more reports of both leaf and stripe rust on wheat than is normal for this time of year, according to a Texas A&M AgriLife Extension Service agronomist.

“There’s been a number of reports out of the Blacklands and Central Texas in general,” said Dr. Clark Neely, AgriLife Extension small grains and oilseed specialist, College Station. “If conditions remain idea for rust, we could see a pretty heavy rust year.”

Wheat rusts are fungal diseases that affect wheat and other small grains, Neely said. Stripe rust prefers cool, moist weather, whereas leaf rust becomes more prevalent later in the spring when temperatures increase.

“Typically, we see leaf rust pressure increasing as stripe rust begins to fade in fields,” he said.

In recent years, fungicide trials in College Station showed leaf rust can reduce yields up to 50 percent on untreated check plots, and stripe rust can be just as devastating if not more so, Neely said.

There are a number of products that will effectively control rust on wheat, he said. Agronomists usually don’t recommend spraying this early because rust pressure is usually too low for there to be an economic advantage.

“But in a number of cases this year, the rust has begun to spread not only in the lower leafs, but onto newer leaves as well,” he said. “And we’ve seen some considerable yellowing of leaves, which means the plant is quite stressed. I think in these cases, spraying may be warranted.”

AgriLife Extension district reporters compiled the following summaries:

The 12 Texas A&M AgriLife Extension Districts

Central: Most counties reported overall conditions – soil moisture, rangeland and pastures, crops – as being good. Livestock were in fair condition with continued supplemental feeding. Farmers were making final preparations to start planting row crops. A few farmers were planting corn. Small grains continued to look good. At the end of the week, temperatures dropped and a cold front brought ice and sleet. On Feb. 19, freezi ng temperatures dinged some fruit trees that were blossoming and stung some winter vegetables. Some producers were making herbicide treatments on coastal Bermuda grass fields. Some brush control was being done.

Coastal Bend: Soil moisture was adequate. Warm, dry days were followed by cold weather again. Preparations for spring planting were slow-going as not all fields were dry enough to get equipment into. But most growers welcomed the wet conditions as it has been several years since a growing season started with a full moisture profile. Some corn was being planted, and fertilizers and other preparations were being made on fields going to grain sorghum and cotton. Growers were topdressing wheat. Some fungicides were also being applied to wheat. Ranchers were grazing cattle on winter pastures with warm-season weeds already emerging. Cattle remained in good condition.

East: The region had warm, mild weather before a cold front brought sleet and freezing rain on Feb. 23. While the weather was warm, winter pastures perked up, and the dryer weather allowed water-logged roots to breathe. In Anderson County, wet conditions prevented truck farmers and row-crop producers from working in the fields. In Henderson County, producers had better field conditions and were sprigging Bermuda grass. Cattle were mostly in good condition, with producers continuing to provide hay and supplemental feed. Cattle were still eating a lot of hay, but most producers still had plenty left. Cattle prices were firm with some classes higher, and demand was strong. Goat prices were good and demand also strong. Ponds and creeks were full. Feral hog reports continued, with damages worse in some counties than others. Fruit and bare-root trees were being planted and pruned. Some growers were planting potatoes and onions. Spr ing calving was in progress.

North: The weather was warmer, with daytime temperatures in the 70s until a cold front brought a wintery mix of ice and snow on Feb. 23. While the warm conditions lasted, farmers were able to get into fields to fertilize small grains and pastures. Livestock producers were able to slow down a little on feeding hay and turn cattle back on winter annual pastures. Hay supplies still looked good and ponds were in good shape. Field preparation for corn planting continued. Winter wheat looked good in many areas. Livestock were in good condition and spring-born calves were growing well. There were reports of heavy feral hog activity.

Panhandle: The region had another weather roller coaster ride with temperatures all over the place. Soil moisture continued to vary widely, with most counties reporting short to adequate. Some producers had a good week for fieldwork and preparing for spring plantings. Stocker cattle were becoming a more common sight on rangeland and wheat pastures. Winter wheat looked good, with dryland and irrigated fields showing sustained growth. Producers were still trying to decide what to plant this spring. Grain sorghum was getting a second look because of the projected low cotton prices. In Hutchinson County, the warm weather prompted weeds to emerge, which was a good thing as it allowed producers to treat early. Cattle on range were being supplemented and remained in fair condition. Lice were becoming a problem in some herds. Rangeland and pastures varied from poor to fair condition, with most counties reporting good to fair.

Rolling Plains: Temperatures were highly variable with limited moisture. Wheat remained in good condition, with most fields growing and greening. However, moisture will be needed soon to maintain good growth and color. Ryegrass was also showing good growth. Rangeland and pastures were in fair to good condition. Cattle remained in decent condition, and some hay was still available.

South: Temperatures were mild with some counties receiving light rain. In the northern part of the region, wheat and oats were in fair to good condition. Producers continued preparing for planting. Continued growth of winter annuals provided good grazing for livestock and wildlife. Rangeland and pastures remained in fair condition. Stock-tank water levels varied, with some tanks near capacity but many still low. Soil moisture was 100 percent adequate in Atascosa, Frio and McMullen counties, and 50 percent adequate in La Salle County. In the eastern part of the region, soil moisture was mostly adequate. Jim Wells County farmers were planting corn as field conditions allowed. Winter wheat was in good to excellent condition and promising good yields. Also in Jim Wells County, soil moisture was good, but rangeland and pastures were not showing much improvement due to persistently low soil temperatures. In Jim Hogg County, scat tered showers occurred throughout the week allowing pastures and rangeland to improve. Supplemental feeding of hay and protein continued. In the western part of the region, some counties received light rains, which helped oats and coastal Bermuda grass. Zapata County ranchers continued to provide supplemental feed, minerals and hay. Some early planted wheat approached boot stage and early seed development. Cabbage harvesting resumed late in the week, and spinach producers continued harvesting the second cuttings of both fresh and processing varieties. Farmers were preparing fields for planting grain sorghum and corn. Soil moisture was from 50 to 100 percent adequate. In the southern part of the region, soil moisture was 60 to 80 percent adequate in Starr County, 100 percent adequate in Hidalgo County and 65 to 75 percent adequate in Willacy County. Farmers were planting spring crops, and the harvesting of sugarcane, vegetables and citrus continued in Hidalgo County. In Starr County , spring planting was nearly completed.

South Plains: The region had mild, spring-like weather during the week, until another cold front arrived over the weekend. Garza County received 0.2 to 1 inch of moisture across the county at the end of the week. Subsoil and topsoil moisture remained short to adequate in most counties. Producers and landlords will have to finalize their farm bill base plantings and any yield reallocation by Feb. 27. Field preparations for the upcoming growing season continued. Pastures and rangeland were in fair to good condition, and cattle were mostly in fair to good condition, with some supplemental feeding during cold spells. For now, it seems the region will continue to experience the roller coaster cold-to-hot cycle for some time.

Southeast: Soil moisture was mostly in the adequate-to-surplus range. Chambers and Brazos counties reported 100 percent adequate moisture. Rangeland and pasture ratings varied widely too, but were mostly fair to good, with fair being the most common rating. Brazos County fields were dry enough for fieldwork, and corn planting began. Chambers County farmers were working fields as long as the weather remained favorable. Grain sorghum was expected to be planted soon. Fort Bend County farmers were waiting on drier weather to plant corn, but hoped to start the first week of March. Livestock were in fair condition. Waller County had spotty showers.

Southwest: Conditions were dry and windy throughout most of the region, but the warmer weather allowed winter forages to use available moisture. Some corn planting started but was limited due to a forecast of colder weather. Lambing and kidding were underway. Wildlife and livestock continued to require supplemental feeding.

West Central: The region had unseasonably warm, dry weather most of the week. The cotton harvest was completed. Gins were finishing up. Winter wheat was improving and in mostly good condition. Winter small grains looked the best they had in many years. Fieldwork was underway in preparation for spring planting. Stock-tank water levels continued to drop. Rangeland and pastures were holding up pretty well for late February. Warmer weather and recent moisture enhanced the growth of grasses, making for better grazing. Supplemental feeding of livestock continued. Cattle prices were still holding steady.

Tracks in the Sand

Published

By

This morning, I walked out into my arena and noticed something that gave me pause. The roping steers had been in there the day before, and even though the ground was wide and level, the sand carried their story. Hoofprints crossed every direction, but in several spots, the same trail was pressed deeper than the rest. Twelve steers had been turned out, yet more than a few chose the exact same path, wearing it down until it stood out from all the other tracks.

Cattle are creatures of habit. Anyone who has spent time around them knows this. They like routine: the same feed, the same water trough, the same shade tree in the pasture. When they are turned loose, they rarely wander without purpose. More often than not, they move together, following the same course as the steer in front of them. There are reasons for this: efficiency, safety, instinct. Walking a beaten path conserves energy, and following the herd is their natural defense. Even in an arena with no real destination, those instincts come through. By the end of a short turnout, you will see the evidence, lines where they have chosen the easiest way to travel and stuck with it.

Out on the range, those lines last longer. Before fences and highways, cattle drives cut deep paths across the land. The Chisholm Trail, which carried herds north from Texas through Oklahoma into Kansas, was walked by millions of cattle in the late 1800s. More than a century later, faint traces of those trails remain, worn so deep by hooves and wagon wheels that the land still carries the mark. On ranches today, you can see the same effect in pastures where cattle walk the same lines between water and grazing. From the ground those trails might look like nothing more than dusty ruts, but from the air, they sometimes stand out as sharp lines winding through otherwise open fields. Cattle do not simply pass over the land; they shape it. Every step adds up.

That simple truth extends beyond livestock. We all make tracks. Our habits and routines are our trails, worn in by repetition, sometimes efficient, sometimes limiting. Like the cow paths, they can serve a purpose, keeping us steady and helping us move forward. But when repeated without thought, they risk becoming ruts, keeping us from stepping into new ground. History offers perspective here too. The old cattle trails built towns and economies, but once railroads and fences changed the landscape, those paths were no longer useful. Sticking to them would have meant going in circles. Progress required something new.


The Tracks We Leave

Standing in the arena, I thought about the kind of tracks I leave behind. Most of mine are not visible in the dirt. They are pressed into my daily life, how I work, the way I handle challenges, the example I set. Some are helpful and worth keeping. Others may have outlived their purpose. The difference comes in knowing when to stay in the track and when to step out of it.

Tomorrow I will drag the arena and smooth it all clean again. The next time the steers are turned in, they will make the same trails. That is their nature. But unlike them, I have a choice. I can decide which paths are worth walking, which ones to change, and what kind of tracks I want to leave for others who might follow.

Tracks tell a story. Sometimes they are only temporary, fading with the next rain. Other times they last for generations, reminders of where herds and people once walked. This morning, the cattle showed me again that even the smallest things on the ranch carry meaning. Their tracks in the arena were not just marks in the sand. They were a lesson: every step matters, and the paths we choose shape more than just the ground beneath our feet.

Grazing North Texas – American Lotus

Published

on

By

Farmers and ranchers are in a very close partnership with Mother Nature. If we really pay attention, she presents us some interesting scenarios.

For example, though they are totally different types of plants, water lilies and prickly pear have a lot in common. They both have strikingly beautiful flowers, both plants are edible, both of them are invaders into their respective habitats, and too much of either one can be an obstacle that we have to deal with.

Many north Texas ranches rely on excavated ponds for livestock water. Any time a pond contains a significant amount of shallow water so that sunlight reaches the bottom, some type of pond weed will develop. The plant family that includes water lilies and lotuses is a common invader in our livestock water.

Water lilies and lotuses are in the same plant family but they are two separate genera. There are easy ways to tell them apart:
• A primary difference is that water lily leaves commonly float on the surface, but lotus leaves can grow above the water line.
• Water lily leaves and flowers are thick and waxy, while lotus leaves and flowers are thin and papery.
• Water lily leaves have a distinct notch in the leaf, while lotus leaves are more rounded.
• Water lily flower petals are pointed, and lotus petals are more rounded.

The photos attached to this writing are from Clay County, and this plant is common across north Texas. American lotus is adapted to a wide area, from Honduras north through Mexico and across the eastern US and into Canada.

American lotus is a perennial, and it is cold tolerant and heat tolerant. It can grow in any pond or slow moving stream that contains shallow water areas. It prefers water with a depth of about 12 inches. Germination can occur from the large lotus seeds. Tubers, or roots, are established in the mud, and long slender stems extend upward. Leaves and flowers are both emergent in that they grow above the water line.

Lotus flowers are fragrant, and yellowish white with rich gold centers. They open in the morning and close by late afternoon, then open again the next day.

Lotus is an edible plant and has a history as a food source. The large tuberous roots, the size of a human arm, were baked like sweet potatoes. The leaves were eaten like spinach, and the large seeds were ground into flour. Stems taste somewhat like beets and were usually peeled before being eaten.

There is a large world-wide industry of cultivating lilies and lotuses in water gardens. According to Dr. Jerry Parsons, Professor and Extension Horticulturist with Texas A&M AgriLife Extension, cultivation of these plants dates back as early as ancient Egypt. Today, anyone with determination and a little money can have a water garden.

In 2011, the 82nd Texas Legislature designated the water lily “Texas Dawn” as the official Texas State Water Lily. Texas Dawn is a hybrid developed by Texas resident Kenneth Landon, a world-renowned expert in the field of water lilies and the director of the International Water Lily collection in San Angelo.

Ducks and other wildlife utilize the large acorn like seeds of American lotus, and submerged portions of all aquatic plants provide some form of wetland habitat. Many of us have tried to pull a bass out of a group of water lilies or lotuses, and I’m sure others have had better luck than I did. Although there can certainly be benefits to lilies, lotuses, and other aquatic plants, they can also infest ponds to the extent that the pond is not functioning correctly.

So, while the rest of the world works hard to grow these plants, ranchers sometimes need to control populations in their stock ponds. Once it gets a foot hold, American lotus can spread aggressively in wetland areas.

The primary issue that encourages American lotus, and most other water weeds, is shallow water. Look closely at a good livestock pond and you will find that the deeper water is basically free of infestation. Any pond will have a certain amount of shallow water that encourages water weed growth, depending upon the terrain at the pond site and how the pond was constructed. Some ranchers who enjoy and utilize wetland habitat may prefer to have ponds with significant shallow water area.

Almost all livestock ponds have a certain life expectancy. Siltation, or movement of soil into the pond bottom through rainfall runoff, is a natural occurrence. How fast siltation occurs into each pond, and how deep the pond was to start with, determines the length of time that the pond will contain adequate depth for dependable water for livestock.

Ponds that develop infestations of water weeds over a large percent of the surface may not have adequate depth to remain a viable water source for livestock during drought periods, especially in western north Texas where evaporation rates are higher.

Mud, or silt, from the pond bottom, can be removed to deepen the water, but this is a very expensive process. It is often more economical to construct a new pond rather than try to remove the silt from an old one. Most of us do not have the funds to continually construct deep water livestock ponds, so we must try to keep existing structures functioning and providing good drinking water for livestock, for as long as we can. Control of pond weeds like American lotus may be necessary, and it can be accomplished.

There is currently no feasible biological control. American lotus can be cut and removed, but this process us usually temporary because lotus can reestablish from seeds and roots.

American lotus can be safely controlled by chemicals. This must be done carefully. If a pond containing a large amount of any pond weeds is treated to remove all of the vegetation, a fish die-off could occur. When the dying weeds decompose, they use up the oxygen in the water and fish can suffocate. If possible, treat only a portion of the area, wait about two weeks, and treat another portion.

The Many Benefits of Rabbit Manure

Published

By

By Landon Moore

Rabbits offer a lot to the home gardener, and perhaps the most useful of all is their waste. Rabbit manure is likely the single most versatile and valuable fertilizer of any animal manure. It’s a “cold” manure, meaning it can be applied directly to plants in any form without the risk of burning them. In contrast, manure from sheep, horses, cows, and especially poultry must be aged before it’s applied, or it may damage plants. Because rabbit manure doesn’t need to be aged, it retains more of its nutrients and is therefore twice as rich as chicken manure and four times more potent than horse or cow manure. Rabbit manure is safe to apply to soil growing edible crops, has virtually no smell, and contains no harmful seeds. It can be used immediately, or be dried, powdered, made into tea, or turned into worm castings. A single trio of rabbits and their offspring can produce up to two cubic yards of fertilizer per year, along with 100 to 200 pounds of meat.

Rabbit manure is in such high demand as a fertilizer, particularly for roses, that it’s often sold online at a premium price. Some rabbitry owners even charge people to come scoop the manure themselves, paying by the bag. Larger rabbitries might sell by the truckload, but many owners keep it all for their own gardens. You may wonder what makes this little mammal’s excrement so uniquely useful. To understand, we first need to look at the qualities that make it special and then explore its various applications.

To begin with, let’s take a closer look at a rabbit’s biology. Contrary to popular belief, rabbits are not rodents but belong to the order Lagomorpha and family Leporidae, along with hares. All domestic rabbits are domesticated European rabbits (Oryctolagus cuniculus) and are unable to produce fertile offspring with American cottontails. Rabbits are considered “pseudo-ruminants” because they have a single-chambered stomach, but they also have an organ called the cecum, which functions similarly to a rumen and makes up about 40% of their digestive tract. They are crepuscular, meaning they are most active at dawn and dusk, typically feeding in the evening.

Rabbits actually produce two kinds of manure. The familiar dry pellets make up most of their waste, while the other type, known as “cecotropes,” is a moist and smelly substance resembling tiny bunches of grapes. Cecotropes are not fully digested, and because rabbits cannot chew their cud, they reingest the cecotropes as they are excreted. This fermented substance allows the rabbit to absorb more nutrients than it would through initial digestion. While cecotropes are occasionally found in cage trays, the feeding behavior that leads to them is usually only witnessed by the rabbit owner.

The dry pellets are the true manure that most people are familiar with. These small, round, dry pellets have almost no smell when kept dry. When crushed, they break down into a powder resembling tiny grass fragments because, in essence, that’s what they are. Some people crush the pellets before applying them to speed up their absorption into the soil, while others appreciate their “slow-release” feature. Additionally, the manure’s water solubility can be exploited in several ways. Soaking a wheelbarrow full of manure creates a potent sludge that can be easily applied to flat surfaces. If the odor is not an issue, the smell will dissipate once the manure is either dissolved by moisture or dried by the sun. Another method is to make manure tea: fill a cloth bag with manure, seal it, and submerge it in a barrel of water for a few weeks. A simpler method involves placing damp manure at the bottom of a barrel, filling it with water, and letting it sit in the sun for a couple of weeks. Stir occasionally, and you’ll have a powerful liquid fertilizer ready for use.

Domestic rabbits should be fed a modern, pelleted feed, which provides all the nutrients they require. This diet eliminates the risk of noxious seeds being present in the manure, making it safe to apply directly to the lawn, especially during winter. Winter and spring rains will break it down, and by late spring, you’ll have a healthy carpet of turf.

Rabbit manure’s nutrient content varies depending on factors like storage, age, and diet, but it generally contains around 2% nitrogen (N), 1.3% phosphorus (P), and 1.2% potassium (K). The Oregon Extension Service gives a range of 3-4.8% nitrogen, 1.5-2.8% phosphorus, and 1-1.3% potassium. Even at the lower end of the scale, rabbit manure has higher nitrogen content than poultry manure and twice the nitrogen content of cattle manure. One reason rabbit manure doesn’t burn plants is due to the biology of birds, which lack bladders and produce more ammonia in their waste. In contrast, rabbits release ammonia in their urine, which is why their manure may have a stronger odor.

Because of its balanced nitrogen-to-phosphorus ratio, rabbit manure promotes a wider variety of species in the same application area. Applying it directly to heavy clay soils will improve them quickly, especially when combined with other organic matter. It can also improve sandy soils by adding texture and helping them retain moisture. Anyone raising rabbits will have a steady supply of manure, as they are efficient producers. A small herd of 17 animals, including their litters, can produce about one ton of manure annually.

Beyond fertilizing, rabbit manure has several other uses. It is considered the best food for earthworms and can be combined with moisture-holding bedding like peat moss, shredded paper, or hay taken from used nestboxes. Many rabbitries (including my own) keep worm beds right under the cages. The resulting castings are rich in nutrients and can be used as-is or incorporated into soil amendments. A couple of feet of manure under a foot of soil in a hotbox can generate enough warmth to start and grow seeds, even in cold climates like Vermont.

In Europe and Asia, the rabbit meat industry is a billion-dollar market. While the Czech Republic leads in per capita consumption (over 8 pounds per person annually), China is the leading producer of rabbit meat. A recent study in China examined the effects of replacing peat moss in seed-starting soil with rabbit manure. The study found no significant difference in germination rates and noted that the manure provided increased nutrients for seedlings. The ideal ratios for seed-starting soil were found to be one-third manure, one-third perlite, and one-third vermiculite, or half manure and half perlite.

Rabbit manure is often overlooked as a nuisance, but as we can see, it’s an incredibly versatile soil conditioner, excellent fertilizer, ideal food for earthworms, and a superior seed-starting medium. Anyone raising rabbits should consider this another benefit, in addition to having a home meat supply, exhibition livestock, or pets.
