1. Drought and Nitrogen Stress Effects on Maize Canopy TemperatureWater scarcity is a major threat to the sustainability of irrigated agriculture. Management practices, such as limited irrigation, that seek to maximize the productivity of a limited water supply are critical. Remote sensing of crop canopy temperature is a useful tool for assessing crop water status and for more precise irrigation management. However, there is potential that nutrient deficiencies could compound the interpretation of water status from leaf temperature by altering leaf color and... A. Carroll, C. Lindsey, J. Baker, B.

2. Soil Water and Plant Canopy Sensor Technologies to Optimize Water and Nutrient UseIn many respects, agricultural technology is doing things now that were only imagined 20 to 30 years ago. Yet, grower tools that provide information and actionable knowledge on water and nutrient availability still remain a challenge. Clearly, rapid development of data transfer and processing platforms to date has provided rich maps of grower fields with overlays of location-specific information but their utility is still limited by our ability to accurately measure the parameters that are the...

3. ManureDB: Creating a Nationwide Manure Test DatabaseManure nutrients serve an important role in crop production, however compared with commercial fertilizers there is a lack of standardized information. When exact manure values are not known, manure book values have been referenced. Recent data from midwestern United States (US) labs indicates manure nutrient levels have changed from book values published by Midwest Plan Service (2004) and American Society of Agricultural and Biological Engineers (2005). Manure laboratory analysis has improved... N.L. Bohl bormann, M.L. Wilson, E.L. Cortus, K. Janni, K. Silverstein, L. Gunderson |
