Nitrous oxide emission from incorporated and surface-applied fertilizers (a) and manures (average of four plants in (b)) applied to an arable sandy soil. Results of an incubation experiment with samples from an arable sand soil. After 7 days, 7 mm water was added to simulate rainfall. See Table 2 for the total emissions of all treatments of this experiment.
