Using gamma irradiation to investigate the influence of nematodes on nitrogen mineralisation in intact soil cores

Abstract
Nematodes are considered to significantly contribute to nitrogen mineralization in soils. Quantification thereof has mostly relied on food web analyses or experiments with artificial microcosms. Gamma irradiation offers the possibility of selectively removing nematodes while leaving soil pore structure intact. The contribution of nematodes to nitrogen mineralization in unamended soil was investigated in an incubation experiment. Intact and disturbed cores were irradiated and inoculated with nematodes extracted from bulk soil. The presence of nematodes increased nitrogen mineralization, although the effect was not always significant, being obscured by an irradiation-induced ammonium flush. The importance of physical disturbance was indicated by increased mineralization in disturbed cores.
