“…However, biological methods for utilization or vegetative bioremediation of salt-affected soils are limited by the growth environment and salinity tolerance of plants, and are usually combined with chemical amendments and/or leaching methods in reclamation of highly saline-sodic soils. Most plants used for soil reclamation in the above studies were annual, shallow-rooted crops or herbaceous plants (Ahmad et al, 1986;Akhter et al, 2004;Ammari et al, 2013;Helalia et al, 1992;Mehanni, 1987). In order to create an attractive landscape, a variety of plant types should be used.…”

“…5), and nearly 30 species of landscape plants, including some salinity-sensitive species, were proposed with survival up to 90% after one or two years. Meanwhile, the approach is applicable to the field condition, which is very different from the traditional reclamation methods mainly used in soil columns, lysimeter experiments, laboratory experiments or greenhouse conditions (Ammari et al, 2013;Gharaibeh et al, 2011Gharaibeh et al, , 2009Hanay et al, 2004;Mahmoodabadi et al, 2013;Miranda et al, 2011;Nayak et al, 2008;Oster et al, 1999;Qadir et al, 1996;Sidhu et al, 2004;Siyal et al, 2010;Somani, 1981).…”

a b s t r a c tSoil salinity, sodicity and saline groundwater are major constraints to the cultivation of landscape plants along oceanic coasts. A sustainable approach for reclaiming saline-sodic soils in coastal environments is evaluated. Soil tillage, phased saline water management based on soil matric potential under dripirrigation, and the installation of a gravel-sand layer were used. Field trials using the method showed that the proposed approach had the advantages of considerable water conservation, more effective salt leaching and successful re-vegetation with desired species. Severely saline soils became non-saline within the 0-40 cm soil profile after one year and non-saline to moderately saline within the 0-120 cm depth after two years. The approach can rather quickly create an attractive landscape and maintain good plant growth. Plants representing nearly 30 landscape species, including some sensitive to salinity were proposed. Plantings showed survival up to 90% after one and two years. This approach demands less water, improves the ecological environments, and will inspire development of coastal areas.

“…However, saline water can be successfully used for irrigation (Malash et al, 2008;Meiri et al, 1992), especially in areas with shortages of fresh water. Many crops, such as cotton , cowpea (Neves et al, 2009), Bermuda grass and Duncan paspalum (Robinson et al, 2004), corn (Yazar et al, 2003), barley (Khoshgoftarmanesh et al, 2003), and beet (Ammari et al, 2013) have been irrigated with the saline water.…”

a b s t r a c tSoil salinity and saline groundwater are major constraints to the cultivation of landscape plants in coastal regions. Soil tillage, drip-irrigation and a gravel-sand layer were used for reclamation of high saline siltsoils in a coastal region of China. Chinese roses (Rosa chinensis), a salt-sensitive species, were planted in the reclaimed soil under field conditions to determine the effects of salinity on rose growth and ion uptake, using five salinity levels of 0.8, 3.1, 4.7, 6.3 and 7.8 dS/m of drip irrigation. Tensiometers were buried at a depth of 20 cm to control the soil matric potential (SMP), keeping the SMP over −5 kPa the first year, and over −10 kPa the second year. Chinese rose relative leaf water deficit, dry matter production, number of flowers, root development and distribution and other plant growth parameters were assessed. Sodium (Na), chloride (Cl), potassium (K), magnesium (Mg) and calcium (Ca) concentrations in roots, stems and leaves were determined. The increasing salinity of irrigation water had adverse effects on rose growth and ion balance, and salt stress had the greatest impact on relative leaf water deficit value. When irrigated with saline water, most roots penetrated beyond 16-19 cm depth into the high-salinity subsoil, which was disadvantageous to the absorption of water and nutrients. The SMP should be controlled at −5 to −10 kPa in the second year for irrigation with saline water of >3 dS/m, to promote a greater concentration of roots in the lower-salt top soil. Rose plants stored most absorbed Na and Cl ions in roots and stems, and Ca, Mg and K in leaves; however, leaf damage still occurred due to greater reductions in Ca/Na, Mg/Na and especially K/Na ratios. Increasing Na concentration and decreasing K/Na ratio had an adverse impact on dry matter production. Therefore, soluble potash should be applied for saline water irrigation to increase the selective absorption ratio of K, to better counteract the effect of the high Na concentrations in this soil.

“…Especially the entire plant biomass regularly incorporated into the soil at an early growth stage heightens the accumulation of SOC and promotes the restoration to crop favourable soil bulk density and hydraulic conductivity. Accumulation of SOC near the soil surface was shown to improve soil hydraulic properties (Benjamin et al 2007, Ammari et al 2013, thus promoting drainage and favouring the leaching of accumulated salts.…”

The decline of soil organic carbon (SOC) has aggravated salinity-related problems in semi-arid irrigation areas of the Awash river basin, Ethiopia. This study aimed at evaluating the performance of potential remediation crops on saline soil and their effectiveness for remediating soil salinity and improving pH, SOC, bulk density (BD) and hydraulic conductivity (HyCo). Rhodes grass (RHG), alfalfa (ALF), sudangrass (SUG) and blue panicgrass (Retz) (BPG) were grown in saline (3–13.9 dS/m) field plots. The crop biomass was incorporated into the soil immediately before flowering. The results show that at high soil salinity levels, BPG and SUG grew well, with the harvesting frequency of BPG being much higher than for SUG. Conversely, the growth of ALF and RHG was strongly inhibited by high soil salinity. Significant (P < 0.05) reduction of soil salinity levels (–3.2 dS/m) and related ionic concentrations, an increase of SOC (0.8% to 1.6%) and improvement of BD and HyCo were observed in BPG plots. The fast-growing nature of BPG in the hot climate of the experimental area resulted in harvests every three weeks and promoted the incorporation of high amounts of biomass to the soil and efficient soil salinity remediation. At moderately saline conditions, ALF also showed a great potential for salinity reclamation (–1.8 dS/m) and SOC accumulation. The cultivation of fast-growing annual crops proved an efficient and low-cost strategy for soil salinity mitigation and the reclamation of salinity-associated soil degradation in irrigation agriculture in Ethiopia.
