Jeffrey Melkonian

The focus of my research is the application of simulation modeling, data analyses and field research to better understand crop production, nitrogen and water fluxes in agricultural and environmental systems, and the impact of the biophysical environment, including high temperature and soil water deficits, on crop production. Research includes examining strategies for nutrient and water management to reduce negative environmental impacts, increase crop production and provide insight into the soil/plant/atmosphere continuum to design more targeted and fruitful experimental and breeding strategies.

Outreach and Extension Focus

My main extension/outreach focus is on improving a well-tested/calibrated dynamic simulation model of water and nitrogen in a maize/soil system to develop improved sidedress nitrogen recommendations for maize production in the major maize production areas in the USA, including New York.
