What are the best methods to treat high salinity of clay soil?

Dear All,

Here in Pakistan we are struggling these days with the salinity of soil problem. The soil types varies from clay to loamy clay and the primary crops grown are rice and sessional vegetable. The irrigation methods adopted are traditional and we know that the over irrigation has rested in this problem. You can see in the picture the severity of the problem.

We are planning to undertake some action research for developing appropriate and location specific soil reclamation technologies to solve this soil salinity problem. Please suggest what are the best methods to treat the saline soil without loosing any crop season.

Treatment of Saline Soils

Saline soils cannot be reclaimed by chemical amendments, conditioners or fertilizers. A field can only be reclaimed by removing salts from the plant root zone. In some cases, selecting salt-tolerant crops may be needed in addition to managing soils.

There are three ways to manage saline soils. First, salts can be moved below the root zone by applying more water than the plant needs. This method is called the leaching requirement method. The second method, where soil moisture conditions dictate, combines the leaching requirement method with artificial drainage. Third, salts can be moved away from the root zone to locations in the soil, other than below the root zone, where they are not harmful. This third method is called managed accumulation.

Dear Junejo Bashir

I am not an expert. I did find an FAO website that will have most of the information you need.
