Normally such lands are reclaimed through chemical amendments like application of gypsum followed by leaching. Reclamation through biological means is another approach. The most promising group of microorganisms are blue-green algae, which are known to establish well in soils with high pH and salt content. The information available on the distribution of blue gree algae, their growth potential, uptake of salts like sodium and potassium and their influence on the yield and physico-chemical properties of such soils is meagre.
