Special Issue Information
Dear Colleagues,
Soil is an essential resource and a vital part of the natural environment from which most of the food in the world is produced. At the same time, soil provides living space for humans as well as essential ecosystem services that are important for water regulation and supply, climate regulation, biodiversity conservation, carbon sequestration, and cultural services.
Naturally saline or sodic soils harbor valuable ecosystems, including 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). The salinization and sodification of soils are among the most serious global threats not only for arid and semi-arid regions but also croplands in coastal regions and, in the case of irrigation with wastewater, in any climate.
Saline soils have excessive levels of soluble salts, which can negatively impact or inhibit plant growth and be toxic to life. Sodic soils have a high amount of adsorbed sodium, which leads to the degradation of soil structure and inhibits plant growth. The question then is what we can do to address this, and the prevention and mitigation of soil salinization in cropland is one such answer.
