Crop selection

From Salinity

The effect of soil salinity can be reduced by selection more salt-tolerant crops or crop varieties. Finding more salt-tolerant crops is an approach that does not reduce the salt accumulation in the soil, but that adjusts to the increase of salts (Adapting to salinity). Under some conditions, crop selection can also be used to improve the natural drainage of soils (Combating salinity). This effect is usually achieved with a deeper and more aggressive rooting system, thus creating more macro-pores and breaking up soil clods so that irrigation water is more effective in leaching of soil salts. Crops can also be selected to provide the maximum level of mulch at the end of the season, thus reducing soil evaporation during the fallow period.
