The document summarizes a field training at the Drainage Improvement and Research Directorate (DIRD) in Pune, India. It describes the week-long program, which included inauguration lectures on drainage systems and soil surveys, site visits to examine water logging and salinity issues, soil and water testing in the lab, and proposing remedial actions. The trainees observed water logging, salt deposits, and crop damage at sites, collected soil and water samples, and developed a contour map showing the affected saline areas based on test results. They recommended preventive measures like drip irrigation and curative actions such as installing cross drains and soil amendments to address the drainage and salinity problems.

12. Field Visit: Sample Collection
 24 samples of soil
were collected from 6
auger holes at
following depths-
1. 0-20 cm
2. 20-40cm
3. 40-80cm
4. 80-120cm

13. Tests on Soil and water Samples
 Tests on soil-
 EC: Electrical
Conductivity
 pH
 Hydraulic
Conductivity
 Saturation
 Mechanical Analysis
 Tests on water-
 EC
 pH
13
PPT Downloaded from http://www.pravinkolhe.com/

14. Test Results
 It is observed that all
the soil samples
were saline. i.e.
EC>3 and pH>8
 The well and drain
water is also saline
with EC>3.

15. Demarcation of affected area
 The points are
marked on the given
catchment map.
 Based on EC values,
contour lines were
marked
 The affected area is
shown on the map
 It is very difficult to
demarcate the area
with only 24 samples.
The accuracy depends
on the number of
samples.
 Remote sensing
technique can be used
to get more accurate
results

16. Remedial Actions proposed
 Preventive measures
 Sprinkler and Drip
Irrigation
 Crop Pattern and crop
rotation
 Leakage Prevention
from canal
 Proper land slope and
drainage arrangement
 Curative measures
 Cross drains
 Controlling Water
Table and Soil
moisture
 Soil Amendment
 Soil leaching
 Bio drainage

17. Remarks and future scope
 Proper drainage is
essential to avoid water
logging
 It is difficult to demarcate
the area on map
accurately.
 Cross drains may be
provided to reduce the
discharge.
 The adjoining land should
be protected from water
logging in future.
 New techniques, like
Remote sensing can be
used to speed up work
accurately.
 Maintenance of existing
drainage scheme is an
important factor.
 Cleaning of natural
nalla.
 Involvement of farmers.
