The Process of Soil Salinization in Irrigated Arid Basins
Quick fact
Soil salinization is a major cause of land degradation, affecting more than 20% of the world's irrigated lands, and it can reduce crop yields by up to 50%.
Why this is interesting
You water your garden and the soil gets saltier instead of cleaner. How can that happen? In some places, irrigation is slowly poisoning the land with salt.
