CRopland Observatory NOdeS (CRONOS): portable, integrated soil-plant-atmosphere monitoring systems
(2022-07)
In croplands the conditions within the soil-plant-atmosphere continuum can differ substantially from those at the closest available weather station, thus there is a need for monitoring stations optimized for deployment in ...
Effects of phosphorous and potassium application timing on a wheat double-crop soybean system
(2022-05)
The wheat-double-crop soybean system is a popular choice for Oklahoma producers, as it allows for two crops in one year, and more revenue in less time. With favorable conditions and proper management, double-crop soybeans ...
Impact of delayed nitrogen application in grain sorghum
(2021-05)
A majority of grain sorghum production occurs in the central to north west portion of Oklahoma, where the average annual rainfall is at or below 900 mm and precipitation events become less frequent. The environment conditions ...
Adaptation of a dynamic crop model for estimating tall fescue forage availability in the southern Great Plains
(2022-05)
Due to interannual and cross-location variability of forage production, ranchers oftenencounter difficulties anticipating which management strategies should be used for optimum pastureland management. While models for ...
Fate of amended phosphorus and sorption of ciprofloxacin in soils
(2020-07)
Environmental contamination from natural and anthropological sources is receiving increased attention due to risks to human and ecological health. Manure from concentrated animal feeding operations is generally applied to ...
Introducing grazable cover crop to wheat systems in Oklahoma
(2019-12)
Winter wheat is a valuable crop in Southern Great Plains (SGP) of the U.S. that grows from fall to spring; then the cropland is kept fallow during summer. Introducing cover crops to this system may reduce soil erosion and ...
Influence of dual top-dress nitrogen applications on winter wheat (Triticum aestivum L.) grain yield
(2021-05)
Winter wheat (Triticum aestivum) is commonly grown throughout Oklahoma and is notably the state's top cash crop. Nitrogen (N) is one of the most heavily applied nutrients in wheat by producers across the state as it is ...
Modeling soil treatment area requirements for conventional septic systems across a climate gradient
(2019-12)
Roughly 19% of homes in the U.S. use onsite wastewater treatment systems (OWTS) for the treatment and dispersal of domestic wastewater. In Oklahoma, upwards of 40% of single-family homes rely on OWTS for effluent removal. ...
Indirect response to yield selection for end-use quality and wheat-sensitivity indicators in hard winter wheat (Triticum aestivum L.) across six breeding cycles and three lineages
(2019-12)
A rising global population necessitates continued genetic improvement of wheat (Triticum aestivum L.), but not without oversight of intended and untended consequences along the way. This oversight is partly to blame for ...
Winter wheat varietal tolerance to Metribuzin tank-mixed with pyroxasulfone
(2021-12)
Metribuzin is a herbicide that is widely used in cropping systems. However, its use in winter wheat in Oklahoma has declined due to varietal sensitivity or lack of information regarding the topic. To evaluate modern wheat ...
