Boron toxicity and deficiency: a review.

Abstract

The soil and environmental factors influencing B toxicity and deficiency in plants are discussed with emphasis given to B toxicity. Topics include sources of B, importance of B to plants, deficiency and toxicity criteria, factors affecting B sorption, quantification of B sorption, difficulties encountered in appraising B deficiency and toxicity limits and confusion in the specification of available B units, Eaton's sand culture work - its assets and weaknesses, B fertilization of crops, B toxicity due to irrigation, and B equilibrium in soils.-from Authors
