Boron Injury to Plants

Excerpts from the report: Boron has been found in toxic concentrations in the soils of many arid regions of the world.

The purposes of this bulletin are (1) to discuss the nature and source of boron, (2) to describe boron-toxicity symptoms, and (3) to suggest remedies for boron toxicity
