“…While this was unexpected, it has been previously documented in the literature (Larson, 2013; van Kessel and Hartley, 2000). The presence of nodules in non‐inoculated soybean plots was likely due to movement of B. japonicum with soil from adjacent inoculated and/or well nodulated plots by wind and/or water, or from un‐cleaned tillage equipment used in adjacent plots during the long‐term study (Lowther and Patrick (1993).…”

“…This seemed to be solely through rhizome growth as no seedlings were found. The ability of Caucasian clover to spread on acid upland soils has been recorded before at pH values of 5.25 (Lucas et al 1981) and 4.9 (Strachan et al (Lowther & Patrick 1993). Most of the white clovers had spread from the original rows by stolon growth and seedling clovers were found occasionally.…”

Growth of 15 legumes was monitored for 3 years on 3 Otago upland soils with 11, 45, or 70 µg g -1 extractable soil aluminium (Al). Lotus pedunculatus and L. corniculatus produced the greatest dry matter over the 3 years, with L. pedunculatus producing superior yields at intermediate and high soil Al sites. Within white clover, types selected for Al tolerance produced similar yields to types selected for Al susceptibility, and four commercial white clover cultivars and an alsike clover (Trifolium hybidum). Caucasian clover (T. ambiguum) spread by rhizomes at the high Al site, but neither Lotus species spread from the planted row. Some white clovers showed limited spread. It is concluded that optimising performance of Lotus and Caucasian clover on these soils will be a more productive strategy than breeding for Al-tolerance in white clover. A00037

“…Trifolium arvense seed is spread in dung or by physical attachment to grazing animals. uneven plant distribution is likely to be exaggerated by lack of suitable germination conditions, failure of seedlings to nodulate in higher altitude tussock grasslands devoid of clover rhizobia (Gaur & lowther 1980;lowther & Patrick 1993), or absence of sites where vegetation is sufficiently depleted to allow colonisation by T. arvense (Palmer 1972;Knight et al 1994; McIntosh & Allen 1998). The annual rainfall in these semi-arid environments is variable.…”

We have measured symbiotic N fixation from the widespread annual Trifolium arvense (haresfoot clover) in two studies in the semi-arid zone of the Mackenzie Basin using a 15 N dilution technique over two growing seasons. Apart from one low value of 69%, the percentage of plant nitrogen derived from the atmosphere (%Ndfa) was consistently high in one study at Tomahawk Gully (82-91%). Calculated inputs of symbiotic N fixation from T. arvense was highly variable over the landscape, and between seasons. Calculated symbiotic N fixation inputs on different landscape units in Tomahawk Gully ranged from <0.1 to 3.4 kg N ha -1 in 2000-01, and from <0.1 to 11.4 kg N ha -1 in 2001-02 when there was more favourable summer rainfall. Weighted mean rates of N fixation over the whole Tomahawk Gully catchment were 0.5 and 1.6 kg N ha -1 , in the respective seasons. In a study at St Cuthbert, the results were variable in the absence of sulphur (S) fertiliser (56-76%). However, the application of 25 kg ha-1 of fertiliser S was associated with an increase in the %Ndfa to 89-92% and a 5½-fold increase in the symbiotically fixed N. Application of small amounts of S fertiliser to areas with naturalised legumes within semiarid grassland offers potential for improving the sustainability of grazed tussock grasslands.
