Pot experiments were conducted in a glasshouse to determine the growth pattern of lettuce, true potato seedlings (TPS) and single node cuttings of TPS in response to biochar. The treatments were arranged in a randomized complete block design with 5 t

The dissociation reactions of copper(II)-humic acid complexes were investigated using a competing ligand spectrophotometric technique. The effects of pH, initial Cu:HA ratio, electrolyte concentration, and predissociation equilibration time on the ra

Availability of soil Cu to plants is dependent on the desorption into the soil solution of Cu from the surfaces of soil colloidal materials. Although there have been many studies of Cu sorption by soils, however, few have examined the process of Cu d

The pseudo-first-order dissociation of copper(II)-humic acid complexes was studied and found to be very heterogeneous with respect to first-order rate constants. A model for heterogeneous kinetics, based on a log-normal distribution of first-order ra

Oxides of Fe and Mn in soils are capable of sorbing large amounts of trace metal ions and can therefore be important in controlling trace metal concentrations in soil solution, and hence trace metal bioavailability in soils. There is, however, relati

Soil solution metal concentrations and hence metal bioavailability are controlled by sorption-desorption reactions at the surfaces of soil colloids. Compared with the numerous studies on sorption of metals by soils, there are relatively few that exam

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 wit
