Figure 5. Peat deposited by tsunami (near Meulaboh) IMPACTS ON SOILS AND CROPS 46 Slavich et al. The effects on soils and crops in affected areas were very site specific and highly variable over small scales of distance (eg. hundreds of meters). Soil salinity after the tsunami was particularly spatially variable with levels depending on time of inundation, depth of marine deposit and site drainage capacity. Agricultural production losses in the year following the tsunami were associated with a combination of social and biophysical constraints. These included lack of farmer capacity and confidence, high soil salinity, waterlogging and flooding due to inadequate drainage and poor local seed quality. Farmers were often not living close to their farms and could not perform timely management. Production losses from high soil salinity could not be ameliorated in the first growing season after the tsunami. Rapid field soil salinity assessments using electro-magnetic induction (EM-38) were used to provide advice to farmers so they could avoid growing crops on the most saline land. Salinity reduction in alluvial floodplain soils used for rice was dependent on flushing of salts from shallow depths in the soil into surface waters using irrigation water or wet season rainfall and subsequent removal in surface drainage. Salts were more readily vertically leached from the rootzone in peat and sandy coastal soils if International Workshop on Post Tsunami Soil Management, 1-2 July 2008 in Bogor, Indonesia
