Managing salt affected lands through local short/long term field experiments - Lessons learnt

In India, chemical degradation of lands is taking place at an annual rate of 0.15-Mha. This is about 10 per cent of the annual global rate of about 1.5-Mha. Due to this, about 3.22 per cent of land area in the country has already become salt affected. Literature search reveals that a myriad of experiments for assessing impacts of varied land/water management strategies on the root zone soil salinization and crop yield reductions have been conducted for managing salt affected lands of India.
