Abstract:
At ADAS Pwllpeiran near Cwmystwyth, mid Wales (clay loam topsoil texture), direct N2O-N emissions were measured from replicated (x3) plots (5 x 15 m) arranged in a randomised block design. Dairy cattle slurry (c.30 m3/ha) and beef cattle FYM (25 t/ha) were applied to permanent grassland in autumn (late-September) and spring (early-May). The cattle slurry was applied using the ADAS small plot applicator set up for surface broadcast and trailing shoe application. The solid manure was spread by hand. In two separate treatments, the commercially available nitrification inhibitor - dicyandiamide (DCD) was applied by knapsack sprayer to the sward after slurry application by surface broadcast and trailing shoe to give a DCD application rate of 10 kg /ha (6.5 kg N/ha). An untreated control treatment was included where no manure was applied. This dataset is of soil mineral nitrogen (SMN) values measured to 0-90 cm depth before experimental treatments were applied. ND = not determined.
