BORON STATUS OF SOILS AS AFFECTED BY DIFFERENT SOIL CHARACTERISTICS-pH, CaCO 3 , ORGANIC MATTER AND CLAY CONTENTS

Abstract

to 9.72 % and about 92 % area surveyed had CaCO3 contents in the range of 3-10 %. The data regarding B concentration in soil reflected an atrocious depiction of B deficiency in the surveyed soils and exhibited that out of 81 samples, 66 sites (82 %) had B concentration in the range of 0.10 to 0.45 μg g-1 and were fall in the deficient range (i.e. <0.50 the critical level) while 12 sites (15 %) having B concentration in the range of 0.46 to 0.55 μg g -1 and only 3 samples had B range 0.56-0.91 μg g -1 . Correlation analysis exhibited that soil B is positively correlated with OM and clay content of soil while it had strong negative correlation with CaCO 3 content and pH.
