To overcome this problem, a dual isotope method using both (15)N and (18)O was proposed. However, O exchange between nitrogen oxides and water has been found to disturb such a method. We here explain in detail a novel dual isotope method that allows to quantify O exchange in denitrification and to differentiate N(2)O production from NN, ND, NCD, and fertilizer denitrification (FD). The method has already been applied to a range of soils with good success.

In Europe extensive grazing by livestock is considered an appropriate management to conserve biodiversity value and to limit shrub encroachment. However, little is known about the influence of shrubs on agronomic values. A gradient analysis of shrub‐invaded temperate grasslands (from shrub‐free to pioneer forest) in Germany was carried out to test the hypothesis that herbage mass and variables describing nutritive value of herbage decrease with increasing shrub encroachment. The herbage mass of dry matter (DM), variables describing the nutritive value of herbage, composition of the vegetation and mean of Ellenberg’s indicator values were analysed with respect to the extent of shrubs. There was a reduction of herbage mass of DM from 3570 to 210 kg ha−1 with increasing shrub encroachment. Metabolizable energy concentration of herbage ranged from 8·9 to 10·2 MJ kg−1 DM and crude protein concentration from 72 to 171 g kg−1 DM, both measures being positively correlated with shrub occurrence. Increasing shrub occurrence was associated with a decrease in water‐soluble carbohydrates concentration (from 151 to 31 g kg−1) and a reduction in the indicator ‘forage value’.

We added a new treatment with (18)O-labelled water to quantify N(2)O from nitrifier denitrification. The theory behind this is that ammonia oxidisers use oxygen (O(2)) from soil air for the oxidation of ammonia (NH(3)) but use H(2)O for the oxidation of the resulting hydroxylamine (NH(2)OH) to nitrite (NO(2)(-)). Thus, N(2)O from nitrification would therefore be expected to reflect the (18)O signature of soil O(2), whereas the (18)O signature of N(2)O from nitrifier denitrification would reflect that of both soil O(2) and H(2)O. It was assumed that (a) there would be no preferential removal of (18)O or (16)O during nitrifier denitrification or denitrification, (b) the (18)O signature of the applied (18)O-labelled water would remain constant over the experimental period, and (c) any O exchange between H(2)(18)O and NO(3)(-) would be negligible under the chosen experimental conditions. These assumptions were tested and validated for a silt loam soil at 50% water-filled pore space (WFPS) following application of 400 mg N kg(-1) dry soil. We compared the results of our new method with those of a conventional inhibition method using 0.02% v/v acetylene (C(2)H(2)) and 80% v/v O(2) in helium. Both the (18)O-(15)N-enrichment and inhibitor methods identified nitrifter denitrification to be a major source of N(2)O, accounting for 44 and 40%, respectively, of N(2)O production over 24 h. However, compared to our (18)O-(15)N-method, the inhibitor method overestimated the contribution from nitrification at the expense of denitrification, probably due to incomplete inhibition of nitrifier denitrification and denitrification by large concentrations Of 02 and a negative effect of C(2)H(2) on denitrification. We consider our new (18)O-(15)N-enrichment method to be more reliable than the use of inhibitors; it enables the distinction between more soil sources of N(2)O than was previously possible and has provided the first direct evidence of the significance of nitrifier denitrification as a source of N(2)O in fertilised arable soil.
