What is it about?
Recently, researchers have been concentrating alternative and environmentally friendly solutions in agricultural drainage. In this study, dry drainage was evaluated by means of both field experiments and a numeric approach based on the HYDRUS-2D. Results showed that soil salinity in the cropped area increased from the soil surface to the bottom, and soil salinity movement was from the cropped to uncropped area. Increasing the ratio of cropped to uncropped width led to an increase in soil salinity of the cropped root zone. Results of modelling showed that HYDRUS-2D simulated soil water content better than soil salinity.

Why is it important?
It could be assumed an alternative environmental friendly drainage method.
Perspectives
Sustainable agriculture can contribute to food security in arid and semi-arid regions if soil salinity in the root zone is kept under control. Environmental friendly drainage methods will reach more attention in future. Dry drainage could be a viable solution in regions with vast saline soils with low amount of water.
