A Re-look at the Diagnostic Criteria for Salt-affected Soils in India

摘要

Reclamation research and practices have a long history in India. However, a concern is posed right in the beginning that despite the excellent work and lead taken by the country for developing technologies for alkali land reclamation and their transformation at the farm level, with more than 1.3 million ha (Mha) of such lands rehabilitated, due credit is not being given in world literature. In fact a 'mini revolution' on alkali/sodic land reclamation in the north-western states of Punjab, Haryana andUP had its own contributions to Green Revolution of 70's. Much of the later efforts during 80's and 90's, though have concentrated on reclamation of waterlogged saline soils but little of the drainage work has so far been translated into successful practices at the farm level.
