BORON DESORPTION IN SOME CALCAREOUS SOILS OF NINEVEH GOVERNORATE / NORTH OF IRAQ

BORON DESORPTION IN SOME CALCAREOUS SOILS OF NINEVEH GOVERNORATE / NORTH OF IRAQ

The investigation was conducted to study the behavior of boron desorption in three calcareous soils, classified as calciorthid. The experiment of boron sorption was conducted by using a different concentrations (0,0.5,1,2,4,6,8,10,20) mg B.L-1 (as boric acid) at 298ْ k while desorption experiment wa...
