EFFECTS OF GRAZING ON MICROBIAL FUNCTIONAL GROUPS INVOLVED IN SOIL N DYNAMICS (2005, methodology): “The usefulness and limitations of this technique are discussed by Vessey (1994) and Minchin et al. (1994).”
Nitrogen Transfer Within and Between Plants Through Common Mycorrhizal Networks (CMNs) (2003, methodology): “The acetylene reduction technique, developed in the mid 1960s, failed to predict accurately the total N contribution from N2 fixation (Hunt and Layzell, 1993; Minchin et al., 1994).”
Sodium chloride-ABA interaction in two common bean (Phaseolus vulgaris) cultivars differing in salinity tolerance (2007, background): “Although the use of such a “closed” system for measuring acetylene reduction does create problems related to an acetylene-induced decline in nitrogenase activity (Minchin et al., 1983), it is still useful for comparative purposes, especially when the assay time is short ( Vessey, 1994 ).”
