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 [...]

Rotate Your Preplant – Preemerge Corn Herbicide Chemistry For Better Control

We all know the importance of mixing different modes of actions in post emerge herbicide programs. One area of corn herbicide management that is easy to neglect is to stay on a consistent rotation of early corn herbicides that are used preplant or preemerge. We are all creatures of habit and resist change. When we [...]

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 [...]

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 [...]

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 [...]

Starter Fertilizer Basics

Applying a starter or pop-up fertilizer at planting has become commonplace.  Here are just a few things to keep in mind as you prepare your planter this spring. By definition, pop-up refers to fertilizer put in direct contact with the seed, and a starter fertilizer is typically placed a couple inches away from the seed [...]
