144 Wahyunto et al. Soil, climate and other physical environment data (slope, topography, surface drainage etc) were used to assess a land suitability levels of various agricultural crop commodities as described in Guidelines for Land Evaluation (ISRI, 2003). Therefore, Physiographic unit as a mapping unit is established in order to present the information of soil characteristic and its environment distribution that have similar potential development of agriculture crops. This mapping unit is based on the similarity of terrain, slope, soil surface texture, drainage, organic layer thickness and tidal, flood inundation and erosion hazard. Land suitability evaluation for selected economic tree crops and other agricultural crops were conducted by using Automated Land Evaluation System (ALES) software package. The crop requirements were based on “Guidelines for Land Evaluation” by ISRI (2003) and related references. Adaptation to the guidelines was made as necessary based on field and laboratory findings. The process of this evaluation is the matching of crop requirements against land qualities or characteristics. The law of minimum constrain is applied to determine the limiting factors of land suitability classes. Selected land quality in this evaluation includes air temperature regimes, water availability, rooting condition, nutrient retention, availability of NPK nutrients, salinity and toxic elements. In this present study, three suitability classes are recognized in the Order S Suitability, and a class for order N Not suitable: Class S1 Highly Suitable: Land having no significant limitations to sustained application of the given land utilization type, or only minor limitations that will not significantly reduce productivity or benefits and will not raise inputs above acceptable level. Class S2 Moderately Suitable: Land having limitations which in aggregate are moderately severe for sustained application of the given land utilization type; the limitations will reduce productivity or benefits and increase required inputs to the extent that the overall advantage to be gained from the use, although still attractive, will be appreciable inferior to that expected on Class S1 land. Class S3 Marginally Suitable: Land having limitations which in aggregate are severe for sustained application of the given land utilization type and will so reduce productivity or benefits, or increase required inputs, that this expenditure will only be marginally justified. N Not Suitable order as the range of land utilization types considered allowed for recommendation of alternatives uses on land whose present use was found to be Not Suitable Based on the actual land suitability assessment, it could be grouped into 4 classes i.e.,: 1 (highly suitable), 2 (moderately suitable), 3 (marginally suitable) and 4 (unsuitable). The main restricting/ limiting factors can be added to the suitability class are: nr (nutrient retention/ International Workshop on Post Tsunami Soil Management, 1-2 July 2008 in Bogor, Indonesia
