Description

Planting perennial forages into saline seep areas is one of several recommended practices for salinity control. Forages differ in their salinity and flood tolerance, with several appropriate species available depending on the specific farm situation. This fact sheet discusses how to choose which salt tolerant forage or forage mixes to grow in saline seeps, which will depend on the desired land use for the affected area.

Description

Ensuring that available precipitation is used for productive crop growth rather than contributing to runoff or groundwater buildup is one of the most practical and cost effective control strategies for contact or slope-change salinity. This approach involves rotations with deep-rooted perennials and annual crops that are more water-use-intensive than traditional cropping practices.

Soil salinity can restrict plant growth and reduce crop yields. The high salt concentration in a saline seep prevents the uptake of water and essential nutrients by plant roots. Various measures... More ≫

Description

Soil salinity can restrict plant growth and reduce crop yields. The high salt concentration in a saline seep prevents the uptake of water and essential nutrients by plant roots. Various measures are used to control and reduce the flow of groundwater that leads to dryland saline seep formation. This fact sheet provides an overview of saline seep formation and how to recognize it, discusses salinity classification, and briefly identifies the main methods of controlling soil salinity.

Description

Dryland saline seeps can be controlled using structural or biological controls. Structural controls for discharge areas include surface water management, subsurface water management and relief wells. Generally, structural controls lower water tables and improve accessibility in discharge areas faster than biological controls. However, structural controls are usually more expensive than biological controls and are not always totally effective.
