Abstract

We have conducted a multi-factorial greenhouse experiment, aimed to improve the understanding of resource uptake mechanisms in terrestrial biosphere models. By measuring the biomass, nitrogen concentration, transpiration, and phosphorus concentration of Kentucky Bluegrass (POA pratensis), we analyzed the effects of full-factorial nitrogen, phosphorus, and water limitations. Our experiment took place from August to December 2019 in the IES Greenhouse. To analyze our data, our team is using R to run analysis and visualize our experimental findings. We hope that our data findings and subsequent research paper will be utilized by earth system modelers to better understand the ways in which plants receive and use nutrients.
