  20. Dholera Soil Reclamation

  21. Dholera Soil Reclamation System 1: Big Beds & Channels (BBC) Ideal for areas close to sea, up to about 10 km from the sea and water table is in less than 2 m from the ground 1 m Cropping area Cropping area Slope < 0.8% towards a sub or main drain 10 m 10 m 10 m 50% area can come under cultivation with in 2 to 3 years & increase to 75% over years

  22. Dholera Soil Reclamation System 2: Broad Bed & Furrow (BBF) Ideal for areas beyond 10 km from the sea and water table is more than 2 m from the ground Cropping area Cropping area 1.5 m Cropping area Cropping area Slope < 0.8% towards a sub or main drain Almost 100% area can come under cultivation within 2 to 3 years
