Soil salinity refers to the concentration of soluble salts in the soil. High levels of salt can negatively affect plant growth by making it difficult for roots to absorb water. This condition often occurs in arid regions or areas with poor drainage, where evaporation leaves salts behind. Excessive soil salinity can lead to reduced crop yields and lower soil fertility. Farmers may use various methods, such as drainage systems or salt-tolerant crops, to manage salinity levels and improve agricultural productivity. Monitoring soil salinity is essential for sustainable land management and ensuring healthy ecosystems.
