Using informative Bayesian priors and on-farm experimentation to predict optimal site-specific nitrogen rates
(2023-05)
Precise site-specific nitrogen applications will reduce excess nitrogen fertilizer run-off and have corresponding environmental benefits. Adoption of site-specific nitrogen application technology has been slow, and many ...
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 ...
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 ...
Soil nitrogen storage and mineralization potential in a winter wheat system under long-term nitrogen fertilization
(2022-05)
In winter wheat systems, crop nitrogen(N) uptake is sourced primarily from inorganic N fertilization and N mineralization from soil organic matter(SOM). N mineralization is a dynamic N cycling process that relies on many ...
Effect of the method and rate of planter applied nitrogen on corn and grain sorghum production
(2023-05)
In Oklahoma corn (Zea mays) and grain sorghum (Sorghum bicolor L) account for nearly 20% of all the total value of farmed cropland in the state. Fertilizer, specifically nitrogen (N) is one of the greatest input cost and ...
