Saadi Shahadha, IPSS graduate student in soil physics, recently won first place in the ‘Examples of Model Application in Field Research’ community graduate student poster competition at the 2018 ASA/CSSA meeting. Saadi received a certificate and a cash award for his poster “Nitrogen Management Effects on Soil Water Dynamics and Wheat Evapotranspiration”.

Saadi is a native of Iraq where he earned his Master’s degree in Soil and Water Sciences from the College of Agriculture – University of Baghdad, Baghdad, Iraq. He is currently a Ph.D. candidate under the guidance of Dr. Ole Wendroth.

Nitrogen fertilization is critical for crop growth and production; however, its effect on the behavior of the crop evapotranspiration and soil water dynamics is not sufficiently understood. Our study reveals the interaction between nitrogen application rate and water dynamics in a field using a computer simulation model that integrates weather, soil, and management impacts on crop growth and evapotranspiration. Nitrogen application rates were appreciably manipulated the crop evapotranspiration and soil water dynamics under high rainfall amounts. However, under low rainfall amount, soil water dynamics and crop evapotranspiration were not affected by nitrogen application rate.
