Approximately 581 h after water application, emission fluxes from both moist treatments did not differ significantly from the control.
The control and moist treatments showed significant inverse correlation between manure NO3− and NH4+ content (Fig. 2).
Reduced conditions may dominate temporarily in a dry soil after watering [29]; furthermore, in the same manner as temporary anoxic conditions triggered denitrification, they also enhanced the activity of methanogenic bacteria, which resulted in large peaks of CH4 fluxes in both moist treatments after watering.
These results suggest that although the manure was dry, both NO3− and NH4+ were being accumulated because only a small amount of denitrification occurred, but as soon as water was added, both nitrifying and denitrifying microorganisms were activated, as also suggested by the sudden increase of more than 2 °C within just 10 min of watering in both moist treatments (Fig. 3b).

A previously published proof of principle phase IIa trial with 113 patients from Kabul showed that bipolar high-frequency (HF) electro-cauterization (EC) of cutaneous leishmaniasis (CL) ulcers and subsequent moist wound treatment (MWT) closed 85% of all Leishmania (L).
Figure 4 shows the temperature trends for the control (dry/loose) and for the moist manure treatments after water application (Experiment 2b).
As in Experiment 1, the CH4 emission peak of both moist manure treatments reached the background level (control) 1 h later.
Moreover, in both moist manure treatments, the pH decreased slightly with respect to the control as soon as water was mixed with the manure.
A second CH4 emission peak was observed for both moist manure treatments at 120 and 410 h after watering, respectively (Fig. 1e).
