Title: Background soil mineral nitrogen: AC0213, Nottinghamshire, 2011

On a commercial dairy farm near Newark, central England (clay loam topsoil texture), direct nitrous oxide (N2O) and ammonia (NH3) emissions were measured from replicated (x3) plots (12 x 14 m) following spring applications of manufactured nitrogen (N) fertilisers to grassland. A control treatment was included where no N fertiliser was applied. Ammonium nitrate (AN) fertiliser (34.5% N) or urea fertiliser (46% N) was applied at a rate of 120 kg N/ha in two equal split applications (late-February and late-March), with or without the commercially available nitrification inhibitor - dicyandiamide (DCD). The DCD was applied in a solution (15 kg DCD/ha) and sprayed onto the plots immediately after N fertiliser application. The N supplied by the DCD was accounted for in the 120 kg N/ha. As separate treatments, AN and urea fertiliser were also applied in four equal splits in late-February, early-March, late-March and early-April i.e. 'little and often'. This dataset is of soil mineral nitrogen (SMN) values measured to 0-90 cm depth before experimental treatments were applied.
