In dry regions where crops need irrigation, salt buildup in the soil is a big problem. Researchers studied ways to control salt and sodicity in fields in the Yellow River Valley. They found that leaching out salts by adding water is crucial for healthy soil. Some areas already have drainage systems, but many still need them. In one area in China, salt-affected land increased due to poor drainage maintenance. Removing salt through harvested crops can help, especially when water has low salt levels. This research aims to find solutions for managing salt in irrigated fields to ensure successful agriculture.
