In order to investigate changes of potassium (K) status in western plain of Rajasthan, two
hundred nine surface (0-15cm depth) soil samples were collected from seventeen tehsils of
three districts (Bikaner, Churu and Jaisalmer). Soils were in general light in texture and
neutral to slightly alkaline in reaction. The OC content of the soils varied from 0.1 to 2.5 g
kg-1. H2O-K and NH4OAc-K ranged from 2.9 to 47.1 (mean value 18.3) mg kg-1 and 13.8
to 202.7 (mean value 91.2) mg kg-1, respectively. The HNO3-K and HCl-K varied from
154.4 to 635.5 (mean value 318.7) mg kg-1 and 8.1 to 99.3 (mean value 40.8) mg kg-1,
respectively. Highly significant positive relationships amongst various fractions of soil K
indicated existence of a dynamic equilibrium between different forms of K. The studied
soils had major portion of their K fraction content in lattice-K it contributed about 87.0 to
90.3 % of total-K because of rich K bearing minerals of soils followed by 6.7 to 9.9 % of
Non-exch-K and 2.3 to 3.3 % of Exch-K towards total-K. On the basis of nutrient index
mostly soils were found medium (68.4 %) in available K.
