Salt-tolerant crops are plants that can grow in soils with high salt concentrations. These crops have developed special adaptations that allow them to survive and thrive in saline environments, which are often unsuitable for traditional agriculture. Examples of salt-tolerant crops include barley, sorghum, and quinoa. These crops are important for food security, especially in regions affected by soil salinization due to factors like irrigation practices and climate change. By cultivating salt-tolerant varieties, farmers can utilize marginal lands and improve agricultural productivity in challenging conditions.
