Abstract
In pot trials with Trifolium pratense cv. Grasslands Huia and Lolium perenne cv. S23 using a range of soils from SE Scotland, plant Co concn were significantly correlated with the amounts of Co extracted from soil with 0.05 M calcium chloride. Plant Co concn were also correlated with soil pH, and decreased with increasing soil pH. There were no significant correlations between plant Co concn and 0.5 M acetic acid-extractable Co, 0.04 M EDTA-extractable Co, isotopically exchangeable Co or total soil Co. Uptake by L. perenne of Co added to the soil was inversely related to both the ability of the soil to sorb Co and to soil pH.
