Description A B S T R A C T
A pot culture study was carried out with Inceptisol and
Vertisol of Chhattisgarh plain. These soils have been
reported to jbe non-responsive to K application.

capacities and
The results indicated that the Vertisol had higher
amount of almost all the soil K fractions than Inceptisol.
This soil has shown higher capacity of K release and for
longer period of time than Inceptisol.
Vertisol also had higher K fixation capacity, specific
adsorption sites and labile K. The adsorption maxima and
binding energy coefficients were also higher. The buffering
capacity of Vertisol was quite higher than Inceptisol. These
results indicates the Vertisol seems to be able to provide
larger amounts of K for longer period of time as compared to
the Inceptisol. However, K ions are held with higher energy
in this soil.
The wheat crop did not responded to K application in
either of the soils. This indicates sufficient soil K
supplies. However, the K release pattern indicated that
these soils may respond to K application in near future. It
is more likely in less buffered Inceptisols.
