Appropriate Land Preparation Methods and Sulphuric Acid Use for Amelioration of Salt Affected Soils

M. Sadiq, G. Hassan, G.A. Chaudhry, N. Hussain, S.M. Mehdi and M. Jamil    

Abstract: Amelioration of saline-sodic soil [EC=2.8 to 26.5 dSM-1, pH=9.10 to 9.73 and SAR=34.68 to 102.50 (m mol l-1)½] through land preparation methods (Cultivator, Rotavator and Disc plough) and subsequent application of Sulphuric acid (@ 20% of gypsum requirement) during crop growth was evaluated in a field study for two years at Jhottianwala site, Tehsil Pindi Bhattian, District, Hafizabad. It was observed that Disc plough was the most efficient field implement which not only ensured good yields but also enhanced soil improvement. Application of sulphuric acid also proved clearly useful by producing higher yields and promoting rapid soil improvement. The gradual enhancement of rice and wheat yields (grain and straw) and significant decrease in salinity parameters were recorded in this strategy within two years.
