Interpretive Summary:

Technical Abstract: Concerns regarding water shortages and environmental quality will continue to increase as human populations increase and demand for water rises. Increasing concerns regarding nutrient contamination of water bodies by agriculture and demands for better nutrient use efficiency are two examples of this awareness. Development of agronomic management practices that reduce soil water evaporation and increase the capacity a soil to store more water per unit volume is an important step that will result in more water being available to crops during the growing season. Development and evaluation of the new management practices, however, can not focus solely on water and crop yield relationships. They must also consider the interactions with N management and cultivar selection. Understanding these interactions will lead to agronomic systems that have enhanced yield stability and profitability over time. They will also increase water and nutrient use efficiencies and reduce negative environmental impacts throughout the world.
