Investigation of Soil Parameters Causing Boron Deficiency in Olive Trees and Methods of Correction under Greek Soil and Climatic Conditions

摘要

Boron (B) is one of the sixteen essential elements required for the normal growth of most higher plants. It has a considerable effect on plants in two ways: either by affecting plant nutrition, if it is deficient in the soil, or because of toxicity if it is present in excessive amounts. It is well known that there is a very narrow range between the concentration of boron in soil solution that causes B deficiency and the concentration that causes toxicity symptoms in plants (Keren and Bingham, 1985).
