Salinity can be reduced by leaching ~ salts Erom the soil ue ing irrigation water that ie low ~ in content of salts. Tile drainage can be used to ~ lower the water table if a suitable outlet ie available. intensive management ie required to reduce the sal inky and ma incain soil productivity. ~ This unit cone iete of very deep, well drained soils on ~ old alluvial Eane and low terraces. These soils formed in alluvium derived dominantly from Mancoe shale. The ~ surface layer ie silty clay loam 12 inches thick. The upper 11 inches of the underlying material are silty ~ clay loam, and tae lower part to a depth of more than ~ 60 inches ie silty clay loam with few Eine gypsum ~ crystals. Permeability of Chia soil is slow. ~ Avaslable water capacity ie moderate. Effective rooting depth ie 60 inches or more. RunafF ie slow, ~ and [he hazard of water erosion ie slight.
