Abstract:
Because boron, as an essential trace element for the growth of most plants, has a rather small range between deficiency and toxicity levels, its relation to clay minerals is important. Studies with montmorillonite of Upton, Wyoming, and illite of Fithian, Illinois, suggest that the negative electric field around clay particles is one of the main factors controlling B adsorption at alkaline pH. -D.F.B.
