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 [...]
