Soil salinity is a term used to characterize the accumulated soluble salts in a soil.
In sufficient quantity it adversely affects plant growth and quality. The ability of a plant to withstand and flourish in saline soils is often referred to as its salinity tolerance. Unlike traditional salinity tolerance testing, which is usually conducted in greenhouses under controlled conditions, this project was long-term and took place under field conditions, where soil moisture fluctuations and other environmental conditions were factors. Soil salinity was measured with the EM38 salinity meter. It is a portable device that is set on or above the soil's surface and measures the soil's electrical conductivity.
