Effect of saline soils and drought on growth of salt tolerant species

To solve the above problems used of conventional techniques to control soil salinization process - use of salt tolerant species will be very useful. Hence, the only way to control the salinization process to maintain the sustainability of landscapes and agricultural fields is to combat the salinization problems with environmentally safe and clean techniques. One of these new techniques is the use of salt removing species. In order to study the potential capacity to remove soil salts, two agronomic species Portulaca oleracea and Tetragonia tetragonioides were evaluated for their efficiency to remove salts from sandy soil. Plants were analysed relatively to total growth and mineral composition of the leaves and soil. According to the results, it was seen that T. tetragonioides is better as a salt removing species and complementary, it has other benefits, which are as follows: high biomass; several harvests; high content of minerals; horticultural importance, leaf vegetable crop; easy multiplication; easy crop management; tolerance to drought. This new technique to control salinity is a powerful and environmental clean tool to maintain the sustainability of the landscape.
