A review of saline-alkali soil improvements in China: Efforts and their impacts on soil properties

It is a great challenge to manage and sustain agricultural production in saline-alkali soils due to their high salt content, poor structure, and low fertility, posing global threats to soil health, land sustainability, and food security. China, accounting for 10.1 % of the world’s saline-alkali land, faces increased pressure as arable land decreases, population increases, and economic grows. Since the 1960s, region-specific reclamation techniques, such as flood irrigation, drip irrigation with mulching, and drainage systems have been employed in China, and have brought about obvious reductions in salinity by over 60 % and pH improvements, with values decreasing from above 9.5 to below 8.5 for saline-alkali…
