In view of earlier reports on the occurrence of saltaffected
shrink-swell soils in the Purna valley areas in
Amravati district of Maharashtra, the present study
was carried out to assess the current nature and
extent of soil degradation due to use of irrigation
water. Results indicate that the irrigation water used to
raise agricultural crops in Amravati, Bhatkuli, Warud
and Daryapur tehsils contains enough soluble Na-ions
and residual sodium carbonate as the water belongs to
C4S2 and C4S1 class of the United States Salinity
Laboratory. The anthropogenic activities by introducing
irrigation have caused severe drainage problem in
the shrink-swell soils of the district, which are highly
clayey and smectitic that have inherent low permeability.
Only exception is the better drained soils of
Warud tehsil, which are endowed with Ca-zeolite that
help to ward off the ill effects of irrigation. The study
thus suggests that continuing the present anthropogenic
activities might render the soils unsuitable for
agricultural production in the future. In contrast, the
soils which are not irrigated do not suffer from any
serious degradation in terms of high exchangeable Na
(ESP) and low saturated hydraulic conductivity
(sHC), suggesting that it would be prudent to encourage
rainfed agriculture in the district under improved
management practices.
