WATERLOGGED AND SALINE SOILS SUPPORT REDUCED CROP PRODUCTION
FIGURE 7.23 The filling of soil pores with water reduces root access to oxygen, and the buildup of salts in soils puts most crop plants under physiological stress. Both of these impacts are reflected in the dead trees and scrub vegetation in this once productive agricultural land in Australia.
