Effect of Organic Matter on Boron Adsorption by Some Soils of Punjab

Abstract

Boron, one of the essential micronutrient elements, has a marked effect on plants, from the standpoint of both plant nutrition and toxicity. Organic matter is one of the main sources of boron in soils. Therefore, the present investigation was undertaken to study the effect of organic matter on boron adsorption by twelve soils of
Punjab. Results revealed that there was a decrease in the adsorption
of boron with the removal of organic matter content in majority of
the soils except in some soils of semi-arid and arid regions. In most
of these soils there was a negligible change in adsorption with the
removal of organic matter.
