Water Logged Reclamation and Saline Soils for Agricultural Purposes topics include: Salinity, water logging and its causes, surface or open drainage, sub-surface or tile drainage, saline and alkaline lands reclamation. Waterlogging is a condition where an area becomes flooded with water, often due to heavy rainfall or poor drainage. This can have severe consequences for agriculture, transportation, and human settlements. Waterlogged and saline soils can be reclaimed through subsurface drainage (SSD). SSD involves using machines to lay PVC pipes at a certain depth. Saline water collects due... Show more
