The Nutrient Use Geographic Information System (NuGIS) integrates multiple tabular and spatial datasets to create county-level estimates of nutrients applied to the soil in fertilizer and livestock ma ...
Objectives: The primary goal of this project is to identify the environmental optimum rate of fertilizer N (i. e. , the rate that provides the greatest yield increase with the lowest FIE) for irrigate ...
Elevated atmospheric CO2 affects growth and yield which then affect processes controlling the supply and losses of N to sustain these increases. This research was undertaken to measure the effects of ...
The effect of elevated carbon dioxide concentration ( CO2 ) on greenhouse gas emissions from semi-arid cropping systems is poorly understood. Two studies were reported during 2010, one from the Austra ...
How will high carbon dioxide concentrations affect the cycling of nitrogen in crop production systems.
