The study looked at how water and salt move in the soil of jujube orchards in South Xinjiang with drip irrigation. They found that salt levels decreased in the topsoil but increased in deeper layers, while water content decreased smoothly with depth. After irrigation, water content increased in all soil layers, but salt levels decreased in the topsoil and increased in deeper layers. Salt was pushed to the outer edges of the wet area by water movement from the drip emitter, creating a low-salt zone in the topsoil.
