2. Waterlogging / Water
logged soil:
Soils saturated with water
for most months of the
year .
Waterlogging causes
oxygen deficiency for plant
roots, ultimately leading to
death of sensitive crops.

Sources of Water Logging
Interruption of surface runoff.
The main cause of waterlogging in Pakistan is seepage
of water from network of canal system.

5. Conti..
 Rainfall: After heavy rainfall rain water percolates
down the pores between soil particles under the action
of gravity.
 Floods: Flood water spreads on the surface of soil in
plains
 Poor water management: Sometimes farmers use
their land unscientifically
 Railway lines /Roads:The construction of railway lines
and roads in food plains interrupted the passage of
runoff water.

6. Effect of Water Logging on Plant Growth
 Stunting growth

7.  Twisting and Yellowing of leaves

8. Soft, spongy areas on
base of leaf
Roots turning dark

9. Lack of flowers/fruits

10. Control Measure of Water logged Soils in Pakistan:
Firstly, water logged condition appear in 1925 in Punjab, Sindh and some
areas of KPK. Different practices are applied and some are effective and
some are not effective.
 Seepage Interceptor Drains
 Tree Plantation along the Spoil Banks
 Surface Drains
 Lining of canals
 Pumping of ground water
