“…Previous studies with this soil excluded a role for excessive Ca uptake [Ca is a potent antitranspirant ( De Silva et al , 1985 )] in limiting leaf gas exchange and biomass accumulation of legume crops ( Rothwell and Dodd, 2014 ). However, tissue or xylem sap P concentrations of limed plants were consistently decreased ( Table 2 ), as in previous observations where liming decreased yield ( Haynes, 1982 ; Maxwell et al , 2012 ). While further investigations of soil P dynamics seem advisable, adding CaCO 3 could precipitate large quantities of CaHPO 4 , thereby making P unavailable to the plant ( Delgado and Torrent, 2000 ).…”

“…However, liming responses are not always positive, and yield reductions can occur even at recommended application rates. This has been attributed to changes in tissue Ca:Mg ratios ( Carran, 1991 ), Mg fixation within the soil ( Sumner et al , 1978 ), or reduced P availability ( Haynes, 1982 ; Maxwell et al , 2012 ). More recent work tested the hypothesis that unregulated Ca uptake by the plant increased root xylem sap calcium ion (Ca 2+ ) concentration or delivery rate, causing a stomatal limitation of photosynthesis that may limit growth of limed legumes.…”

“…The application of lime is used to increase soil pH in agricultural systems. However this practice is often uneconomic on extensive farms due to high aerial application costs (Maxwell et al 2014). Legumes which are able to persist and thrive in low pH soils, or with low inputs of lime and P, would be well suited to this environment and could be of major benefit to dryland farming systems.…”

Pasture legumes provide critical nitrogen inputs but fail to persist in typical acidic low P fertility upland soils. Alternative legume species for these environments are urgently sought. Twelve novel legume species were grown for 42 weeks under glasshouse conditions in an acidic upland New Zealand soil. Phosphorus (P) was applied at eight rates (0, 10, 30, 60, 100, 250, 500, 1500 mg kg -1 soil) or lime (100% CaCO 3 ) at five rates (0, 2, 5, 8, 15 t ha -1 equivalent). Annual species grew on average for 25 weeks, while perennial species grew for 42 weeks. Yield was measured and herbage was analysed for macro and micro elements and soils analysed for pH, exchangeable Al and Olsen P. P responses differed substantially between legume species which were likely driven by genetic adaptations to low phosphorus environments. Critical shoot P concentrations for optimum yield were identified and ranged from 0.23 (tagasaste) to 0.39 % P (falcata lucerne). Arrow leaf, subterranean and balansa clovers had the greatest yield increase at low P inputs (100 mg P kg -1 ) and show promise as alternatives to white clover. Lime treatments increased the yield of all species to a point beyond which yield decreased with further additions. Increased yield was primarily driven by decreased soil exchangeable aluminium (Al) concentrations and to a lesser extent by increased soil P and molybdenum (Mo) availability, while decreases were driven by lower soil P and boron (B) availability at high pH. Thresholds for soil exchangeable Al differed between legume species. Species with higher Al thresholds (7 -8 mg Al kg -1 ) were tagasaste, lotus, persian and gland clovers and falcata lucerne. These species show promise for acid soil environments with soil Al issues and should now be investigated further in field experiments. For many of these legume species this represents new and critical information.

“…Considerable research has also been conducted in Australia investigating subterranean clover (T. subterraneum) responses to added P (Paynter 1993;Bolland & Paynter 1994;Bolland 1995;Cayley & Hannah 1995;Cayley et al 1998). The literature addressing P responses of T. subterraneum and naturalized adventive annual legumes under New Zealand conditions is limited (Beale et al 1993;Dodd & Orr 1995;Maxwell et al 2010Maxwell et al , 2012. In a pot trial using two P rates, Caradus (1980) reported a P response by striated, haresfoot and suckling clovers.…”

Maintaining and increasing legume abundance is a critical component of pastoral intensification, increasing nitrogen inputs to nitrogen deficient New Zealand high and hill country pastures and improving feed quality. Establishment and persistence of traditionally sown legume species white clover (Trifolium repens) and subterranean clover (T. subterraneum) is often limited in summer-dry high country. In contrast, naturalized, adventive annual pasture legume species such as cluster clover (T. glomeratum), haresfoot clover (T. arvense), striated clover (T. striatum) and suckling clover (T. dubium) persist on low fertility, summer-dry high and hill country slopes, although little is known about the edaphic requirements of these species. A glasshouse study was conducted to determine the response and efficiency of these four pasture legume species to increasing levels of available phosphorus (P) in a typical, low fertility, acidic New Zealand high country soil, comparing against white clover and subterranean clover as 'reference' species. Trifolium subterraneum was the most productive species (4.4 g dry matter [DM]/pot) and T. striatum yielded the least (0.8 g DM/pot). The order of greatest yield DM response was T. subterraneum T. arvense T. repens T. dubium ] T. glomeratum T. striatum, while the P application rates at which maximum yield occurred varied between species. Mean shoot P uptake was highest for T. subterraneum and lowest for T. striatum (24.1 and 3.8 mg P/pot, respectively). P-response efficiency by species was in the order of T. subterraneum T. arvense T. glomeratum T. repens T. dubium T. striatum. Implications for low input, extensive grazing systems in high and hill country are discussed. Trifolium arvense and T. glomeratum show potential for further P response investigation under field conditions.
