Dear all
The water logging with salinity has lead for the ban on Paddy. Read more about it at: http://www.downtoearth.org.in/content/khap-panchayat-bans-paddy#comment-10872
The comments and suggestions made on this key issue were pasted below as:

In talking the issues related with water logging and salinity,Khap panchayat bans paddy may be the immediate remedy (DTE, 15th Nov. 2012). The problem raised due to when the groundwater level rose with the arrival of the Jawaharlal Nehru canal.
Now the question is how long the local farmers can stop the ban on paddy? It is true that the farmers should have the pattern of alternative crops for better utility of the land for better production.
As indicated earlier, the presence of water in the Jawaharlal Nehru Canal has resulted for the rise in the groundwater. At the same time the initiative taken for lowering the groundwater level have note resulted for sustainable solutions.
In addition to the initiates made already, the problem is some thing different than the expected. The water leakages from the Canal are resulting for the higher level of groundwater along the sides of the canal. So the focus should be towards the mapping of the water leakages along the Canal.
The techniques of Geological and Geophysical can be used for:$ mapping the leakages along the canal both laterally and vertically and
$ to map the groundwater levels.
Based on this data and knowing the dynamics of the groundwater and severity of water leakages from the canal, the action plans include:
* Measures for sealing the leakages
* points can be selected for drilling "Water Discharging Wells".
* Monitoring of these wells on regular basis helps to maintain the groundwater levels.
* Soil & water testing helps to know the salinity.
These measures will help to monitor the groundwater levels, salinity and extent of leakages. Proper study on these issues further helps to grow paddy and other crops with desired change in patterns.
