In pot trials using a range of soils from South-East Scotland, plant cobalt concentrations were significantly correlated with the amounts of cobalt extracted from soil with 0-05 M calcium chloride. Plant cobalt concentrations were also correlated with soil pH, showing a decrease with increasing soil p H . There were no significant correlations between plant cobalt concentrations and 0.5 M acetic acid-extractable cobalt, 0.04 M EDTA-extractable cobalt, isotopically exchangeable cobalt or total soil cobalt.Uptake of cobalt by ryegrass from cobalt added to the soil was inversely related to both the ability of the soil to sorb cobalt and to soil p H .

“…Field experiments were carried out at four sites, three on mineral soils and one on a deep acid peat; details of sites and the experimental treatments were given in a previous paper. 12 At all four sites, the experimental treatments were applied to mixed grass and clover swards, which had been established the previous year under a cereal crop on the mineral soils and by direct reseeding on the peat.…”

The effects of the application of fertilisers, especially N, and trace elements on the contents of Cu and Mo in mixed grassland herbage and its main constituent species, have been studied. Results have been obtained from field experiments on three mineral soils and on a deep acid peat, the herbage having been cut at stages of growth considered suitable for conservation as silage three or four times per year for at least three successive years.Applying N without Cu reduced the Cu content in herbage in three experiments. At these three sites, applied Cu produced slightly higher yields and a small increase in the Cu content in herbage, which was greater with than without applied N. In the fourth experiment, on a soil containing adequate Cu, applying N increased the Cu content in mixed herbage, ryegrass and cocksfoot, except with 56 kg ha-' per cut, where the content in mixed herbage was reduced slightly by the elimination of clover. Where the soil was adequately supplied with Cu, either naturally or from additions of this element, ciovers contained more Cu than grasses. The Cu content was higher in herbage from the October than the June cuts, the mid-summer cuts having intermediate contents. Cu extracted by 0 . 0 5~ EDTA from the soils agreed with the effects on herbage contents, but a higher level of extractable Cu may be required for intensive grass than for optimum cereal production.Applying Mo had no effect on yield, but produced a large increase in the Mo content in herbage on a mineral soil; the increase was greater in clover than in ryegrass. On peat, applied Mo had much smaller effects on herbage contents, giving similar increases in both clover and ryegrass. Applying N reduced the Mo content in herbage, both in the absence and presence of added Mo. The effects of the latter decreased gradually in successive years. Applying P, especially at high rates, resulted in s!ightly lower Cu and Mo contents in herbage.
