N2O and N2 fluxes from cow urine patches with different loading rates of N in an Andisol in southern Chile

Summary
INTRODUCTION Grazed pasture soils are a potential source of nitrous oxide (N 2 O) due to elevated inorganic N pools. N 2 O is the dominant source of microbial denitrification, and under suitable conditions, N 2 O may be reduced in the soil to the environmentally harmless di-nitrogen gas (N 2 ). One of the key nitrogen (N) sources is urine deposited from grazing animals. The loading rate of N i...
