Abstract

The article presents a study which examines biotic and abiotic controls over soil nitric oxide (NO) and nitrous oxide (N2O) emissions across a gradient of aboveground Prosopis biomass growing on two soil types. The correlation of NO emissions and nitrification potential with temperature is stated. It is inferred that mesquite encroachment in grasslands increases NO emissions in a spatially explicit manner influenced by soil type and aboveground biomass.
