47 Slavich et al. they were not affected by tidal estuarine water. Areas affected by tidal inundation have remained too saline for crop production and are more suited to aquaculture. Monitoring of rootzone salinity using ground based electromagnetic induction technology (EM38) in conjunction with soil and water analysis over time provided useful information on the impact, location and recovery of agricultural soils in NAD province following the tsunami. Provision of necessary technical equipment and training of key personnel immediately following the tsunami was successful in providing insights into salt levels and movement at various sites and in advising farmers when salt levels were satisfactory for cropping. Classic stress responses of rice to salinity were observed. These included lack of grain filling with more severe effects observed in areas of rice paddies where water circulation was poor (i.e. lowest parts of the field) (Figure 6). This is because salt tends to be transported to low areas of rice fields and then concentrate through evaporation. The lack of rice grain filling also declined in subsequent seasons which would be expected as the salinity also decreased. Figure 6. Rice is low part of field was affected by salinity more severely and did not produce grain Some of the mud deposits were higher in phosphorous, iron and zinc than the underlying soil. However, the levels of micronutrients (Cu, Fe, Mn, Ni, and Zn) in soils affected by the tsunami were not consistently International Workshop on Post Tsunami Soil Management, 1-2 July 2008 in Bogor, Indonesia
48 Slavich et al. higher than those which occurred in soils not affected. Some tsunami clay and organic deposits may have potential to provide additional nutrients suitable for crops. However, the potential benefits of these additional nutrients can not be realised until soil salinity declines and soil structure is adequate. Changes to drainage patterns at both field and landscape levels caused waterlogging and flooding losses to palawija crops in large areas (Figure 7). Production losses were also associated with lack of irrigation water in the dry season. Coastal peanut crops in very light sandy soils showed empty pods consistent with calcium deficiency and moisture stress during pod-fill. It is expected that the use of organic amendments in these soils will assist peanut production by improving soil water holding capacity and plant available calcium. Soybean variety evaluation conducted at Desa Baro successfully identified some new varieties with adaptation to production in NAD province and potentially higher yields than current local varieties. Figure 7. Water logged and salt affected peanuts in 2005 CONCLUSIONS Agricultural land rehabilitation approaches need to be site specific and tailored to local conditions. It was not possible to make generalised “one size fits all” agricultural recommendations in assisting farmers restore their production systems.
