Influence of lime on the Ni transfer into plants

In a two years pot experiment with a sod-podzolic, acid sandy loam, contaminated with nickel (Ni) and treated with increased lime doses, the Ni transfer from soil to plants was studied. It was shown that lime addition significantly decreased mobile Ni concentration in soil, Ni concentration in plants and consequently its transfer factor. The sigmoidal Bolzman equation estimates the range of changes in parameters of Ca and Ni interaction. It is suggested as an estimation function for the description of related processes in the soil-plant system.
