Special Issue Information
Dear Colleagues,
Soil is an essential resource and a vital part of the natural environment from which most global food is produced. At the same time, soil provides living space for humans, as well as essential ecosystem services which are important for water regulation and supply, climate regulation, biodiversity conservation, carbon sequestration, and cultural services.
There are naturally saline or sodic soils, which harbor valuable ecosystems and include a range of plants that are adapted to extreme conditions. However, secondary salinity and sodicity can develop or increase rapidly in response to unsustainable human activities, posing a threat to agricultural production, food security, the provision of essential ecosystem services, as well as the achievement of the Sustainable Development Goals (SDGs). Salinization and sodification of soils are among the most serious global threats to arid and semi-arid regions, but also for croplands in coastal regions and in cases of irrigation with wastewater in any climate.
Saline soils have excessive levels of soluble salts, which can negatively impact or inhibit plant growth and can be toxic to life. Sodic soils have a high amount of adsorbed sodium, which leads to degradation of soil structure and inhibits plant growth. There are few approaches which can help to prevent these: halting soil salinization and boosting soil productivity.
