Abstract:
A study was carried out in
field experimental area of directorate of land
reclamation Punjab, Lahore, to investigate
the effect of experimentally quantified
commercial sulphuric acid (76%) on
residual sodium carbonate (RSC) of water,
soil quality and crop yield. The findings
were clear indications of effectiveness of
acid injection approach to treat water. The
sulphuric acid application reduced the RSC
value of 6.1 to nil by making (T2) slight
change in EC of water. This treated water
not only improved the soil quality by
decreasing its calcareousness from 20 to
17.2 making soil soft while the same
increased to 23 in control (T1), where not
acid amendment was done. Similarly, SAR
of soil was also restricted from an increase
by acid treated water rather than the control
set of experiment. To make RSC nil, 5.19
liters of sulphuric acids were injected in
water for 3 acre inch irrigation. An increase
of 16.65% in grain yield of wheat crop was
observed upon harvesting in T2, in
comparison with control. Ascorbic acid and
total phenolic contents (TPC) were also high
in T2, followed by T3 and T1. All the
changes in soil parameters and crop yield
were found statistically significant.
