Problems in Production Fields—Saline and Sodic Soils
- Tom M. DeSutter
Soils high in soluble salts can be very difficult to manage and remediate. Salt-affected soils are grouped into four categories: 1) saline, 2) sodic, 3) saline–sodic, and 4) normal. This chapter describes these four classes of salt-affected soils and introduces methodologies that are used to identify and manage these problem soils. You will learn: 1) the definitions and criterion for salt-affected soils; 2) field and laboratory methods to diagnose salinity and sodicity of soil; 3) impacts of these soils on crop productivity; and 4) methods for managing these soils. Although total remediation of salinity and sodicity may not be possible,this chapter outlines some traditional and alternative approaches for diagnosing salt-affected soils and for increasing crop production on fields negatively affected by salts.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
