The four pillars of Saline agriculture
Because of the generally negative effects of salinity on crop yields, salinization threatens food production and food security in many areas in the world.
Saline agriculture is a possible solution: food is produced on salt-affected soils and/or using salt or brackish water for irrigation water.
The latter strategy also saves fresh water, which is a scarce resource on this planet, and even more so in those areas generally affected by salinization.
To make saline agriculture possible, conventional farming techniques would need to be adapted. We have identified four pillars of agriculture, all of which would need to be adapted to make saline agriculture possible:
- crop and cultivar choice
- soil management
