Abstract:
On a commercial farm near Ross-on-Wye, west England (sandy clay loam topsoil texture), direct N2O-N emissions were measured from replicated (x3) plots (5 x 15 m) arranged in a randomised block design. Cattle slurry (c.40 m3/ha), broiler litter (6.5 t/ha) and layer manure (6.5 t/ha) were applied to cereal stubble in the autumn (early-September) and to winter wheat in the spring (late-February). Cattle FYM (30 t/ha) was also applied in the autumn. The cattle slurry was applied using the ADAS small plot applicator set up for surface broadcast and trailing hose application. 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. Following manure application, measurements of direct N2O-N were made over c.12 months, using 5 static chambers (0.8 m2 total surface area) per plot and analysed by gas chromatography. This dataset is of daily nitrous oxide flux (g N2O-N/ha/d) measurements. 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.
