To improve saline and alkaline soils should be soluble pistachio shell salinity and alkalinity (sodium) of

The maximum range of root activity and the upper soil horizons are washed away. Use only

Fresh water is not recommended to improve alkaline saline soils. If used

Only fresh water leads to alkalinity of the soil, because by leaching ions

Calcium and magnesium are washed away and sodium ions remain. The severity of the problem is up

It is so much that the farmer after one to two washes with fresh water of the building

It destroys its soil so much that it destroys trees. To

For this reason, it is recommended to use calcium sulfate modifier when rinsing

Juicy or agricultural gypsum should be given to the soil. Use of concentrated sulfuric acid

It also has a role similar to agricultural gypsum, with the difference that it responds faster than gypsum

Gives. As a precaution, leaf acid is preferred. سدیم و

Exchangeable magnesium adhering to the surface of soil particles is not washed away by water alone. Calcium

Resulting from gypsum dissolution and acid substituted sodium and magnesium performance

Calcium sulphate in gypsum with sodium and magnesium released by calcium, salt

Produces sodium sulfate solution which is easily combined with additional solution salts

Washed salinity and saline and alkaline soils become a neutral and balanced soil in terms of

It becomes salt and alkalinity.
