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...

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 to gravity and is then pumped out into surface drains. Reclamation of waterlogged saline soils can have significant benefits: Crop yields increase by more than 50% for paddy and more than 100% in wheat and cotton Cropping intensity improves by 40% Farmers' income increases by 2-3 times The water table depth decreases by 13.7% Drain water salinity is reduced by 98% The yield obtained with drainage is 10-20% more than the yield obtained without drainage Leaching in the presence of subsurface drainage can remove excess salts from the root zone. Leaching methods include flushing and leaching, which can be accomplished through continuous ponding or intermittent ponding. Show less
