Abstract:

Hot water soluble (hws) boron and ammonium oxalate-oxalic acid (Ao-oA) extractable molybdenum were determined in fifty soil samples collected from 25 sites representing important soil series of Kohat district. Their values were correlated with the physico-chemical characteristics of the soils studied. Boron and molybdenum contents in the topsoil ranged from 0.37 to 1.66 ppm and 0.14 to 1.41 ppm and in the sub-soil from 0.50 to 2.02 ppm and 0.12 to 1.64 ppm, respectively. Boron was found deficient in 92% soil samples, while 8% soil samples contained marginal content of this element. None of the soil series was found deficient in -available Mo. Boron gave significant positive correlation with electrical conductivity, pH and potassium of the soils. Available Mo gave significant positive correlation with clay content while significant negative correlation with sand content of the sub-soil.
