Maximize Your Fertilizer Dollars

Corry Israel — Tue, 14 Dec 2021 17:49:05 +0000

The availability and the price of fertilizer have been going in opposite directions – and not in the direction we would like to see. We are dealing with inflation and supply chain disruptions that are unprecedented – with no apparent plan to alleviate the problems. Producers have clamored to get fertilizer applied this past fall [...]

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

Tracy Smith — Fri, 01 Sep 2017 08:00:17 +0000

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 [...]

Split Nitrogen Applications Are Evolving

Tracy Smith — Mon, 15 May 2017 08:00:51 +0000

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 nitrogen 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 [...]

Fertility Requirements of Alfalfa Production

Tracy Smith — Wed, 01 Feb 2017 08:00:26 +0000

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

Tracy Smith — Sat, 01 Oct 2016 08:00:58 +0000

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?

Tracy Smith — Fri, 15 Jul 2016 08:00:33 +0000

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

Tracy Smith — Fri, 01 Jul 2016 08:00:58 +0000

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 [...]
