This is the greenhouse data for Clark et al. "Environmental sustainability of future fertilizers: Tradeoffs between ammonia volatilization and nitrate leaching for 11 enhanced efficiency fertilizers." The data quantifies the environmental performance (NH3 volatilization, N leaching) and agronomic performance (yield) for 11 enhanced efficiency fertilizers on two soil types (Minnesota sandy loam, Iowa clay loam). Yield results are published separately (Dolda et al. in review) but are included here for completeness. See Table S1 in the publication to cross reference brand names with active ingredients.
