Copper sulphate, sodium molybdate, magnesium sulphate, cobalt sulphate and basic slag were applied to the seedbed of a reseeded Welsh upland pasture in conjunction with lime at 1 ton and 4 tons per acre. The higher rate of liming produced a lower uptake of applied Co and a slightly higher uptake of applied Mo. The Cu and Mg contents of the herbage were similar at both rates of liming. Copper sulphate at 20 lb per acre increased the Cu content of the herbage by a factor of about 1·5 during the first growing season, but this effect was not significant during the subsequent seasons. Sodium molydbate at 4 oz per acre increased the Mo content of the herbage by a factor of about 2·0 in the first season after application, but this effect declined and was not observed after 4 years. Cobalt sulphate at 2 ib per acre increased the Co content of the herbage by a factor of about 4·0 in the first season after application, but this effect had declined to a factor of about 1·5 four years later. Basic slag at 6·75 cwt per acre each spring slightly increased the Mo and Mg contents of the herbage, but had no effect on its Co or Cu contents. Magnesium sulphate at 5 cwt per acre produced no significant effects on the Mg content of the herbage.
