With aridity increasing, various plant species of forage crops become gradually less numerous to finally disappear. In Dry Steppe ecosystems xerophylic half-shrubs and salt-tolerant plants replace the grasses. However, the ash content is higher in these species. This is attributed not only to a higher concentration of major ash elements in the plant tissue, but also to the exposure to finely dispersed dust adhered to the plants exterior (Table 9).

However, efforts to improve crop performance under environmental stresses have not yet been very fruitful, mainly because the fundamental mechanisms of stress tolerance in plants remain to be completely understood. A genetic approach to the development of specific stress-tolerant crop varieties requires as a pre-requisite the identification of key genetic determinants of stress tolerance-related genes or quantitative trait loci (QTL). The existence of salt-tolerant plants (halophytes) and differences in salt tolerance between genotypes within salt-sensitive plant (gly-cophytes) species clearly indicates that there is a genetic basis to salt response.

Saltwater marsh soils under flooded conditions have neutral pH and support salt-tolerant plants. Many of these soils contain large amounts of FeSj. Pyrite formation occurs as a result of high sulfate concentrations of seawater associated with high concentrations of Fe + in the sediments and rapid accumulation of organic matter (see Chapter 11 for details). 

Salt-tolerant plants, known as halophytes, can be used to restore damt ed soils. Once toxic salt levels have been reduced, the plants die and other species of plants and grasses can be planted or restored to previously unusable lands. These technologies are particularly valuable in areas subject to urine accumulation.
