Figure 6

Graphs of paired NO-N fluxes (ug g−1 dry soil d−1) from soil amended with non-freeze-dried (N; dark grey diamonds) or freeze-dried and rehydrated (F; light grey crosses) sheep urine samples in FD-2: (a) LM1, (b) LM2, (c) LM3, (d) HM4, (e) HM5, (f) HM6. Gaps in data points (particularly between 2 and 6 days) result from instrument issues (i.e. no data was recorded during this time) in addition, a system error in the automated DENIS resulted in no data being recorded for LM1-N and only data for LM1-F is shown.
