Arid conditions favor salt accumulation.
It is important in passive subirrigation to wash out the system from time to time to remove salt accumulation.
Many of the islands in the delta have a garland of riparian trees along their borders, but in the middle they are bare: symptoms of salt accumulation (see photo of the delta).
Arid conditions favour salt accumulation.
Proper irrigation management can prevent salt accumulation by providing adequate drainage water to leach added salts from the soil.
Disrupting drainage patterns that provide leaching can also result in salt accumulations.
Porous fabric containers have been tried but have high water loss and salt accumulation.
However, even after the water intrusion has been treated, these salt accumulations still persist.
The remaining soil problem in Montana, besides nitrogen exhaustion and erosion, is salinization, a process involving salt accumulation in soil and groundwater.
This salt accumulation can lead chotts to have particularly high albedo, albeit with comparable variability as well.
