DPP01 Drought experiment nested within the phosphorus plots experiment at Konza Prairie

We explore how nutrient-altered tallgrass prairie responds to drought. Seven years of nutrient treatments (control, nitrogen (N), phosphorus (P), and N+P) resulted in significantly different plant communities. Within this experimental context we imposed a three-year drought followed by three years of recovery from drought. We hypothesized (1) the plant functional types would have different responses to drought; (2) the different community types would vary in their resistance to drought; and (3) the control and P treated plots, where N is limited, will have a greater increase in standing biomass production in the previously droughted plots compared to the non-droughted plots.
