Nitrogen Applications Offer Growers Flexibility

As with any biological system, very few decisions about production inputs in your operation ever have a single solution. The advantages and disadvantages of the options need to be thoroughly analyzed. Agronomists often consider the four R’s when developing a fertilization scheme: The Right product, at the Right time, at the Right rate, at the Right place. Specifically considering nitrogen fertilization options, [...]

Soil Testing Methods

Tyler Gardner, American Agricultural Laboratory While soil testing is frequently overshadowed by newer and more exciting areas of crop production, it remains an integral component of maximum yield production. The particular methods used to obtain soil nutrient levels are often overlooked by producers when choosing a consulting service and agricultural laboratory, and the [...]

The Importance of Managing Potassium Deficiency in Cotton

Cotton can be a tricky plant to manage. Unlike most other row crops in the US, it is an indeterminate, perennial plant farmed like an annual through the use of plant growth regulator hormones (PGR). PGRs are used to attempt to shut down or slow the vegetative growth of the cotton and force it into [...]

Start Preparing For Your 2018 Wheat Crop – Now!

Wheat harvest will wrap up shortly across the High Plains.  It was an interesting year.  A dry fall and winter was followed by an unusually wet spring.  Late freeze and snow events added to the roller coaster that is growing wheat! As you prepare for sowing wheat again this fall, it is time to look [...]

How Split Applications Are Evolving

Recently I was asked to contribute to an article Precision Ag Professional was putting together.  The point of view from the corn belt on split applications was interesting.  I was a little surprised at the implied low number of split applications being made in the corn belt since this is a well-established practice under a [...]

Fertility Requirements of Alfalfa Production

Alfalfa production in Southwest Kansas is a profitable crop. Initial seed costs are comparable with corn, but when amortized out for a five to seven year stand, costs are around $20 per acre per year.  Furthermore, since alfalfa is a legume crop, nitrogen fertilizer is not required for production, assuming seed was inoculated and nodules [...]

Phosphate Fertilizers

Most farmers understand the importance of nitrogen fertilizers in relation to yield, but many do not fully realize the importance of phosphorus fertilizers in maximizing yields and improving fertilizer uptake efficiencies. Phosphorus fertilizers are the second most important fertilizers for many crops throughout the High Plains.  Unlike nitrogen which is a mobile nutrient, phosphate ions [...]

Why The Sudden Interest In Corn Nitrogen Models?

Risk management appears to top the list of reasons. Weather causes uncertainty, which leads to questions about nitrogen movement. Nitrogen (N) losses and nitrogen use vary with the weather. Many areas this spring were wetter than normal, so growers ask where did the nitrogen go? Do I have enough N remaining in that field to [...]

Potassium

One of the most challenging nutrients to manage for crop production in the Southern Plains is potassium. Many of our soils in this region are sandy and are derived from low potassium parent materials. It is not unusual for our staff to recommend fairly high application rates to these soils to push production. Several of [...]

Making Production Decisions In A Lower Commodity Price Environment

Over the past few years, we have gotten accustomed to selling corn in the $5.00 to $7.00 range. These higher prices allowed us to take a little higher risk approach to push yields goals higher than what we normally might. Through this process, we learn quicker whether there is an adequate return on investment for [...]

Profitability In 2016

As growers look at 2016, many are asking, “how do we make a profit?”.  There are many ways to look at the issue.  A former mentor of mine taught me that with any business; P= I-E.  That is; profit equals income minus expenses.  Many growers look to cutting expenses in challenging times, but that may [...]

CQIQ Part II: More of What We Learned in Oklahoma City

In the last post, CQIQ Part I, we highlighted a few of the topics covered at our annual conference CQIQ (Crop Quest Information Quest).  This post will wrap up the series on major topics discussed during CQIQ. Dr. Jessica Davis, Colorado State University, presented a good review of manure utilization and management during our Thursday [...]

Organic Matter, What Is It & What Does It Do?

I came across an article in the Noble Foundation’s Ag News & Views Newsletter, a number of years ago, that does a very good job of explaining what organic matter actually does in the soil.  Much of this article was taken from that particular article. Most of us have a general sense that organic matter [...]

Teff Grass Production

With the recent dry summers in the Southern Plains, interest in moisture conserving alternative crops has increased. One new forage that has shown great potential in North Central Oklahoma is teff grass. Teff is a summer annual forage native to Ethiopia that is very broadly adapted. It can tolerate a wide range of soil conditions, [...]

You Can’t Buy a Miracle in a Jug

One of the most common questions we hear is: “What do you think of this fertilizer? It is supposed to increase my yield by 20 bushel.” But at what cost? Looking at some of these specialty fertilizer analyses, household well water has more nutrient value.  Now, we are not saying these products do not have [...]
