Overview
We grew corn (zea mays, Reid’s Yellow Dent Open Pollinated Corn Seed, Bradley Seed Brand) in a Yale Science Building research greenhouse (affiliated with Yale University’s Marsh Botanical Garden’s plant growth facility) controlled by an Argus Prime automation system with and without basalt amendments under average growing season conditions. We measured the ammonia (NH3) fluxes, and soil pH, and temperature. System settings and measurements taken are listed in Table 1.
