“…The reduction in Mn content reported here is consistent with results of Reith e/ a/. (1964) and Mudd (1970), although Hemingway (1962) found Mn and Cu to be increased by fertilizer N. Reduction in Mo is in accord with results of Hemingway (1962) and Whitelaw (1984).…”

“…Since the early work of Stewart andHolmes (1953) andHemingway (1961;1962) on the effects offertilizers on herbage mineral composition, research has shown that reseeding and liming of upland pasture can result in mineral imbalance leading to potential Cu deficiency (Whitelaw et al, 1979), while increasing the nitrogen (N) supply on lowland Lolium perenne swards has been shown to result in changes in the ratios of N/S and of K; (Ca + Mg) (Whitehead et al, 1978). Mudd (1970) concluded that nitrogen fertilizer depressed herbage Mn and I, increased herbage Cu and Zn but had no effect on Co content. However, the consequences of intensification of the management of permanent grassland on herbage mineral status are less well understood, in particular the relative effects of reseeding and of increasing fertilizer N application on the concentration of various minerals.…”

The concentration of mineral elements in herbage from permanent swards of mixed species composition (predominantly Agrostis spp., Holcus lanatus. Festuca rubra, Lolium perenne, Poa spp., etc.) was compared with that from sown perennial ryegrass {Lolium perenne) at two fertilizer rates (0 and 300 kg N ha"' year"', both with P and K) and with L perennelTrifolium repens (at 0 N with P and K). The investigation was conducted over four years at sixteen contrasting sites in England and Wales. Herbage samples for mineral analysis were taken at first and fourth harvests (May and August) each year from plots under 4-weekly cutting. There was a wide degree of variation between sites, particularly for concentrations of Ca, Mg, Na and all trace elements analysed. Herbage from L. perenne reseeds had significantly higher concentrations of Ca, Mg, Na, Co and S, but K, Mo, Zn, Cu and P were generally lower than in the permanent swards. L. perennelT. repens swards had the highest concentration of major cations, but trace element levels were generally intermediate between those for 0 N permanent and L perenne swards. Fertilizer N reduced concentrations of Ca, Mn, Mo and S, and increased Mg, Na and Zn, with no consistent effects on K, Co and Cu. Herbage at harvest 4, compared with harvest 1, had higher Ca, Mg, Na, Mn, Zn and S. Permanent and L perenne swards responded similarly to fertilizer N and between harvest dates. Results are discussed in relation to previous reports of botanical and fertilizer effects on mineral concentrations, and the mineral requirements of livestock. Changes in mineral concentration resulting from reseeding permanent swards are considered unlikely to increase mineral-related livestock disorders, and in many cases could be beneficial, though problems might arise on sites where some elements, e.g. Cu and Mg, are low.

“…The variation in soil fertility is often related to below-ground species richness that may influence the function of ecosystems via nutrient supply (Naeem et al, 1995;Ekschmitt & Griffiths, 1998) which in turn influences the botanical composition (Høgh-Jensen & Schjoerring, 2010;Rasmussen et al, 2007). Increasing the supply of N to temporary grassland was shown by Mudd (1970) to decrease herbage Mn, which is confirmed in this study (data not shown). This is further underlined in the observed dilution of the Mn concentration in grasses coexisting with legumes.…”

“…Increasingly it is appreciated that additional species may profoundly affect ecosystem functions and provisional services (Naeem et al, 1995;Vitousek et al, 1997;Belesky et al, 2001;Høgh-Jensen et al, 2006;Gylfadó ttir et al, 2007). Management optimization of temporary grassland systems, which are only kept for a few years (Allen et al 2011) must take species traits and soil fertility into consideration (Whitehead et al, 1978;Hopkins et al, 1994).…”
