Soil salinity is a brutal environmental issue that limits crop productivity, because most crop plants are sensitive to salt. Salinisation can be caused by natural processes, such as mineral
weathering or the gradual withdrawal of an ocean. It can also come about through artificial processes, such as the use of irrigation and road salt. Poor irrigation techniques have
increased salinity in much of the world’s farmland. Soil salinisation threatens major economic losses for countries with large agricultural sectors, both by lowering the available
crop yield and the costly methods used in trying to solve the issue. So far attempts to deal with the problem have been largely unsuccessful, with the costs making the techniques
inaccessible for smallholder farmers.
