Other claims from this paper (19)
- Intervention effect Spring sowing improved Atriplex prostrata germination and survival.
- Intervention effect Spring sowing improved Spergularia marina germination and survival.
- Intervention effect Autumn sowing improved Hordeum jubatum germination and survival.
- Intervention effect Sowing season did not significantly affect Salicornia europaea germination or survival.
- Intervention effect Sowing season did not significantly affect Suaeda calceoliformis germination or survival.
- Observation Salicornia europaea germinated and survived poorly in both seasons.
- Observation Spring-sown A. prostrata and Suaeda and autumn-sown H. jubatum and Spergularia produced the highest yields.
- Association High soil conductivity reduced survival and yield of spring-sown A. prostrata, H. jubatum and Spergularia.
- Association High soil conductivity did not significantly affect autumn sowings.
- Observation Autumn sowing increased root biomass allocation in H. jubatum, Spergularia and Suaeda.
- Observation All tested species accumulated more sodium and chloride than other ions.
- Observation Autumn-sown Suaeda accumulated significantly more sodium than spring-sown plants.
- Observation Plant tissue ash content ranged from 15% to 35%.
- Observation Hordeum jubatum roots contained significantly more sodium than shoots.
- Intervention effect Halophytes other than Salicornia significantly reduced soil salinity by 4% to 17% versus controls.
- Observation Leaching reduced control-plot sodium by 44% over four years.
- Intervention effect Vegetated plots lost 59% sodium over four years.
- Recommendation Authors judged halophyte establishment capable of restoring salt-affected sites to agricultural or native-plant use.
- Recommendation Authors recommend matching plants to site conditions, fertilizer and water inputs, and regular harvest.
