Arid and Semiarid Soils: Characteristics and Challenges for Revegetation, Reclamation, and Mitigation
Revegetation, reclamation, and mitigation become increasingly difficult as water becomes the most limiting factor for plant growth. These problems often are compounded in semiarid and arid regions by salinity, which further restricts plant growth, and sodicity, which destroys soil structure. The inability to establish surface vegetative cover exacerbates problems with both wind and water erosion. This presentation will address which soil and climate properties to evaluate to predict the success of revegetation efforts, and identify methods to address the specific management challenges encountered in working with arid and semiarid region soils.
Attendees of the webinar will come away with an improved understanding of the challenges of working in waterways as well as new tools and approaches to address these challenges.
Discuss primary limiting factors to revegetation in arid/semiarid regions.
Provide measures and characteristics of saline and sodic soils.
Identify plant salinit tolerance and potential mitigation strategies for revegetation and erosion control.
