Prussic Acid, Nitrate Poisoning and Grass Tetany in Beef Cattle

Eddie Funderburg, Ed.D., senior soils and crops consultant, offers a comprehensive summary of data on prussic acid, nitrate poisoning and grass tetany to aid beef cattle producers in health management and herd protection.

Bermudagrass as a Forage and Hay Crop in the Southern Great Plains

Eddie Funderburg, Ed.D., senior soils and crops consultant, presents a thorough overview of bermudagrass, a warm-season perennial grass, including recommendations for its establishment and management as a forage and hay crop.

Economics of Fertilizing Bermudagrass for Cow-Calf Production

Fertilizer prices have fallen in recent months. Unfortunately, so have cattle prices. Does it pay to fertilize bermudagrass pastures to increase carrying capacity in times like these? To answer this...

Consultant shares best times to apply phosphorus, potassium

Sometimes, a rancher takes a soil sample, sends it to a laboratory and the recommendation calls for phosphorus (P) and potassium (K). The rancher knows nitrogen should be applied near the time of...

When two or more products are physically incompatible, an emulsion may form.

Organic matter serves important role in soil health

The contributions of soil organic matter and how to maintain or increase it.

Soil test values can vary across years

Following these steps should help you develop a better nutrient management program through use of soil testing.

Proper management increases weed control success

A well-managed and properly stocked pasture should not need herbicides every year. A little time spent scouting may save you a lot of unnecessary time and money on spraying when your weed population is not high enough to justify it.

Herbicides control sandbur infestation

I've had more calls on sandbur control in 2014 than I can ever remember. While it is obviously too late to do anything about them this year, plans can be made for next year.

How to Take a Soil Sample

Why do you need to take a soil sample? How do you take a good soil sample? How often do you need to sample?

Using Aminopyralid Preemergent in Pastures for Western Ragweed Control

Western ragweed (Ambrosia psilostachya) is considered one of the most common weeds in pastures and rangeland in the Southern Great Plains. It is an aggressive competitor with grasses and is generally...

Herbicides control blackberries

June is usually the best month to control blackberries in pastures and rangeland in the Southern Great Plains.

Fertilizer rates affect bermudagrass varieties differently

There are many varieties of bermudagrass, and they respond to nitrogen fertilizer in different ways. A research study was conducted to see if fertilizer could be used more efficiently by fertilizing different varieties to their optimum response rate.

Proper liming, fertilizing increases winter pasture profit

Lime and fertilizer make up a substantial portion of the costs of producing winter pasture. Lime may or may not be needed - only a soil test can tell you for sure. If lime is recommended, its application can pay good dividends.

Research yields findings for greenbrier control

Most ranchers are aware that greenbrier can be a problem in pastures and rangeland, and is hard to control. There are various ideas on how to control greenbrier.

Inventory Weeds Now for Control Next Year

Summer is a good time to identify problem weeds and work out a weed-control plan for the following year.

Is Nitrogen Fertilizer Worth the Cost for Winter Pasture?

At the time of writing, urea costs about $750 per ton. This means that a pound of nitrogen from urea costs about 82 cents. This is a very high price and leads to the logical question, "Is it worth the cost to fertilize winter pasture for stockers?" I'll try to answer this question, but let's define the ground rules.

Hay Choices for Cattle Producers and Equine Enthusiasts

Cattle producers and equine enthusiasts in the Southern Great Plains rely heavily on introduced warm-season grasses for their winter hay needs. Primarily, these grasses are either bermudagrass or old world bluestem varieties.

Laboratory Analysis Changes

The Noble Research Institute has changed its contract laboratory for analytical services (soil, water, manure, lime and fertilizer) from Ward Laboratories, Inc., in Kearney, Neb., to Servi-Tech Laboratory Services in Amarillo, Texas.

Is Fertilizing Native Grass Profitable?

A high percentage of the grazing land in our area is native grass. Most ranchers do not fertilize native grass because it is widely thought that it is unprofitable to do so. In fact, one of the appealing characteristics of native grass systems is that they do relatively well with minimal inputs.

Effect of Fertilizer on Yield of Native Grass

Fertilization of native grass fields is generally not recommended in the Southern Great Plains region of the United States. The primary reason for not fertilizing native grass is the belief that the...

Effect of Nitrogen Rate on Yield of Nine Warm-season Introduced Perennial Forage Varieties

When ranchers think about planting an introduced summer perennial forage variety, there are usually two questions. One is, "Do hybrid varieties that do well in research tests with heavy fertilization...

Pasture and Hay Field Weed Control for Texas

Good weed control can be achieved in pastures and hay fields if attention to detail is followed. It is a matter of targeting the correct weed, at the proper growth stage, with a labeled herbicide,...

You May Not Need to Use Nitrogen on Wheat in 2011

As we approach the end of 2011, many soil sample results have considerably higher than average amounts of nitrates, especially in wheat and winter pasture fields.

Does Lime Pay on Winter Pasture?

Let's say you look at the results from your soil sample and see there is a recommendation for lime. You check around and discover this is going to cost $40-$50 per acre. A normal person would question whether the value received from liming is worth the cost.

Have You Seen the Price of Nitrogen Fertilizer?

In April 2001, I wrote an article on high nitrogen prices. Ten years later, the question persists, and, yes, nitrogen fertilizer prices are even higher.

Common Mistakes in Growing Alfalfa

With high protein prices, many people are thinking about growing alfalfa, some for the first time ever. While alfalfa can be very profitable, there are some common mistakes that can take you from profitability to loss quickly.

Nitrogen Losses From Urea

There are many thoughts regarding how much nitrogen is lost from applying urea on pastures and hay fields. If applied incorrectly, up to 40 percent of the nitrogen applied as urea can be vaporized and lost as a gas.

Poultry Litter for Fertilizer

There has been increased interest in using poultry litter as fertilizer since fertilizer prices have skyrocketed. Poultry litter has long been used near the point of production, but high transportation costs for its low analysis has limited its use to within about 50 miles of poultry houses.

Profit Potential in Wheat for Grain

Since it looks like wheat may be $8 per bushel at harvest in 2009, many producers are considering planting it strictly for grain. This can be profitable in some situations with good management, cost control and high yields. Unfortunately, costs have increased at a very fast pace and have diminished profit margins.

Brush Control without Spraying Leaves

Some people want to control brush, but don't have a sprayer, have too much brush to use a sprayer or just want to do selective brush control. There are several options, each with advantages and disadvantages.

December can be a fairly slow month regarding soil and crops issues, and it may be a good time to plan your strategy for the use of fertilizer and herbicides in 2006.

Consider These Items Before Spraying

Spring has arrived, and many ranchers' thoughts turn to killing weeds. Before you hook up the trusty (or in some cases, rusty) sprayer and give 'er a go, think about the these things.
