Summary
The importance of the Zn buffer power and its influence on the Zn concentration in soil solution was investigated in a simulatory experiment where the soil in question, previously treated with Zn and compacted to known bulk density, was eluted with 0.01M CaCl2 under constant hydraulic head. The data so obtained were correlated with Zn, uptake by maize. The correlation coefficient for effluent Znvs total Zn uptake improved, remarkably when the corresponding Zn buffer power was also incorporated into the computations. It is concluded from this and the earlier investigation2 that the Zn buffer power is the most important parameter governing Zn uptake by maize.
