We are interested in varying osmotic potentials because we want to know if crop death seen on saltwater intruded farm fields is due to the inability of plants to pull water out of the soil matrix or because of salt toxicity. This work will be complemented by another experiment of seed germination at varying sodium chloride (NaCl) concentrations in order to tease apart whether seeds are experiencing osmotic stress or ionic/salt stress.
This first year has been a year of logistics! Between field work on the lower eastern shore, to aggregate fractionation at the University of Maryland College Park, to seed germination experiments and George Washington University, I feel like the ring leader of a scientific circus. The second year can only be crazier and more exciting with all the data to analyze and a story to tell!
