CONCLUSIONS 149 Wahyunto et al. Land evaluation is essentially the matching between requirements for specific use, and the properties of the land. The result of land evaluation is a suitability assessment for specific agricultural landuse, which includes information on limiting factors as source input for improving management to get optimal production. In each of Physiographic Mapping Unit at scale 1:25,000 one or more limiting factors of the land may exist for agricultural development. It depends on the land and soil characteristics, environment, intensity and its effect to soil management. Some of those limiting factors such as drainage, tidal and flood inundation, depth of peat layer, slope steepness are relatively difficult to improve within a short period. Nutrient content availability (fertility) level is relatively easy to be improved by applying fertilizer and organic matter. The coastal zone and flat alluvial plain regions in Aceh Barat have sub-soils of generally sandy material with shallow ground water tables. The depth of sandy material is approximately 40 cm. Soil salinity does not seem to be the problem because it has been leached by the relatively high rainfall. However the reconstruction of the drainage system should be prioritized to avoid inundating agricultural land in the rainy season. Estimated potential suitable for high economic value for tree crops in the marine ecosystem are: (i) area close to the coastal line potential suitable crops are coconut, and cemara laut. (ii) in the ancient sandy beach suitable for banana, rambutan, mango and rubber. Limiting factors such as: rooting condition (sandy material of sub-soil), poor drainage and water inundation. (iii) in the swalle is potential for paddy field. Estimated potential suitable tree crops in the alluvial ecosystem are: coconut, cacao, banana, mango, sukun, cacao. In the valley floor and backswamp is suitable for paddy field and other food crops. The limiting factor is poorly drainage. In the region of peat soil ecosystem estimated potential suitable tree crops are: (1) shallow peat/ peat depth 3 meter is recommended for conservation due to unstable ecosystem. The limiting factor is poorly drainage. In the region of undulating to rolling tectonic plain estimated potential suitable tree crops are: rubber, oil palm, rambutan. The limiting factors are: erosion hazard, and low fertility.
