Abstract:
On a SRUC research farm near Penicuik, eastern Scotland (sandy loam topsoil texture), direct N2O-N emissions were measured from replicated (x3) plots (6 x 12 m) arranged in a randomised block design. Cattle slurry (c.40 m3/ha), broiler litter (5.7 t/ha in autumn, 8 t/ha in spring) and layer manure (14.5 t/ha in autumn and 16.4 t/ha in spring) were applied to cereal stubble in the autumn (early-October) and to winter wheat in the spring (early-April). Cattle FYM (c.30 t/ha) was also applied in the autumn. The cattle slurry was applied using watering cans simulating trailing hose and surface broadcast application and the solid manures were spread by hand. In the autumn the surface broadcast cattle slurry and the poultry manures were incorporated within 24 hours of application. An untreated control treatment was included where no manure was applied. This dataset contains topsoil mineral nitrogen values measured to a depth of 0-10 cm. Measurements were taken from all treatments, on selected days when nitrous oxide flux measurements were also made. In both the spring and autumn, the first measurement is a 'background' measurement i.e. before any treatments were applied. ND = not determined. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
