Description

The goal of the Native Prairie Protocol is to avoid the disturbance of sensitive native grasslands associated with remediation of salt contamination when it can be shown that the contamination is not causing an adverse effect. Native grassland is very sensitive to disturbance. The Native Prairie Protocol provides an approach for identifying sites where adverse effects from elevated salinity are not occurring, and are not expected to occur in the future. Sites that meet the conditions specified in the Native Prairie Protocol are eligible for reclamation certification without further remediation even though salt concentrations may exceed Alberta Tier 1 guidelines.

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.

Salt tolerance of plants

Description

Plant species vary in how well they tolerate salt-affected soils. Some plants will tolerate high levels of salinity while others can tolerate little or no salinity. This brief fact sheet looks at... More ≫

Description

Plant species vary in how well they tolerate salt-affected soils. Some plants will tolerate high levels of salinity while others can tolerate little or no salinity. This brief fact sheet looks at how soil salinity is measured and categorized, and then presents a table delineating the salt tolerance of various types of plants, including field crops, forages, vegetables, and trees and shrubs.

Acceptable salinity, sodicity and pH values for boreal forest reclamation

This report examines plant species used in reclamation and their tolerances for soil salinity, sodicity and pH. The information for each species was obtained from a review of the literature and... More ≫

Description

This report examines plant species used in reclamation and their tolerances for soil salinity, sodicity and pH. The information for each species was obtained from a review of the literature and unpublished information conveyed through personal interviews with people conducting research in this area or working in reclamation. The objective of this report is to determine if the current values for soil salinity, sodicity and pH need to be revised to reflect plant species' tolerances for these soil parameters. The results indicate that the current values used for soil salinity, sodicity and pH should not be changed at this time.

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.
