An evaluation of land suitability for cocoa cultivation was carried out in Southeast Sulawesi, Indonesia, according to its climatic conditions, as well as physical, morphological, and chemical soil characteristics. Land suitability evaluation is essential since cocoa production correlates positively with land characteristics. Purposive sampling with a survey method was used in this study. There were 11 sampling locations, comprising eight and three villages in North Kolaka and East Kolaka, respectively. Results showed that land suitability class for cocoa cultivation in North Kolaka is S2 (suitable) at 1,721 hectares in Pumbolo village and S1 (very suitable) in the other seven sampling locations, covering an area of 7,018 hectares in Rante Baru, Lasusua, Koroha, Watunohu, Lelehao, Tambuha, and Puurau village. Land suitability for cocoa production in all sampling locations in East Kolaka is S2 (suitable), covering an area of 11,213 hectares in Poli-Polia, Palenga Jaya, and Toasu village. The limiting factors in all sampling locations include P2O5 availability, humidity, and effective soil depth. Therefore, the addition of phosphorus fertilizers becomes one of the priority strategies to increase cocoa productivity. From an economic feasibility point of view, the R/C ratio in North Kolaka and East Kolaka is 1.56 and 2.12, respectively, which means that cocoa farming has a great potential to be developed in the two locations.

Pepper (Piper nigrum L.) has a high selling value. The price of pepper in the domestic or international market that is always high can be a great opportunity to increase farmers’ income. Tirtomoyo District is dominated by hilly areas with common soil types of Litosol and Latosol. As one of the efforts to develop the regional economic rate, especially in hilly areas, pepper cultivation can be a solution offered by the agricultural sector. The study was conducted using an explorative descriptive survey method consisting of field observation and laboratory analysis. The analytical unit used was Land Map Unit (LMU) obtained from soil map. The sampling sites were selected using purposive sampling method according to the research objectives and representing the study area. The results show that the actual land suitability for pepper in Tirtomoyo District is marginally suitable (S3) for all LMU. The main limiting factors are water availability and nutrient availability, thus the Tirtomoyo district still have potency for pepper cultivation by applying some improvement measures such as fertilization, irrigation, organic material addition, and cover crop planting.

The aim of the study was to determine the level of suitability of wetland rice fields in the area before flash floods and post flash floods Lawe Tua Makmur Village, Lawe Alas Subdistrict, Southeast Aceh Regency and soil analysis at the Research and Development Laboratory of PT. Nusa Pusaka Kencana Analytical & Qc. Laboratory Bahilang Tebing Tinggi Medan in April 2016 and December 2017. It is carried out by a survey method that refers to the extent of the limiting factor of land characteristics. Data from observations in the field and data from laboratory analysis were matched to the criteria for the suitability of wetland rice classes. The results showed that the actual land suitability class for paddy rice in the area prior to banjir bandang was according to marginal / S3 (r, f) and the potential land suitability class was marginal / S3 (r). Actual land suitability class for wetland crops in the post-banjir bandang area according to marginal / S3 (r, f, n) and potential land suitability classes according to marginal / S3 (r). The limiting factor is the permanent texture of the soil so that it cannot be repaired and the limiting factors of CEC, organic C and N-total can still be improved by adding organic matter and fertilizing with nitrogen.

The need for bananas in Bali far exceeds the production. To obtain optimal production according to their genetic potential, the development of banana cultivation should be preceded by a land suitability evaluation study. This study aims to evaluate the land suitability based on agroecological parameters such as rainfall, altitude, dry moon, slope, and considering current land use.The results showed that 257.467 ha or 46.16% of the area of Bali Province has the potential to be planted with bananas.Buleleng Regency has the widest area for the development of banana plants, followed by Karangasem, Tabanan, Jembrana and Bangli. Denpasar town has the smallest suitable area.Based on the observed agroclimate parameters, slope is the most severe limiting factor in banana cultivation, while rainfall, altitude, and dry months are not significant limiting factors. Recommended land use for the development of banana plants is garden, grass, rain-fed rice field, scrub, bare land, and moor.

In the present study and research work, land suitability evaluation (qualitative classification) was made for the Bilverdy research station of the Islamic Azad University in East Azarbaijan for wheat, barley, alfalfa, maize and safflower. The Simple Limitation Method (SLM), the Limitation Method regarding Number and Intensity (LMNI) and the Parametric Methods (PM) such as the square-root and the Storie methods were used. The landscape, climate and soil and characteristics that influence suitability of the land for particular crops have been combined according to the adopted methodology. Economic factors were excluded and moderate level of management was assumed. The results of different methods show that the most important limiting factors are climate, pH, organic matter (OM), gravel, salinity and sodicity, taken either alone or in combination. For safflower, the cation exchange capacity (CEC) can be added to these factors. Evaluation by the SLM and LMNI methods result in similar suitability classes, which confirms previous findings by other researchers for the same crops. However, in many cases the use of parametric methods, especially the square-root method, turned to be more realistic in distinguishing separate suitability classes. This study not only compares different methods and their results but also evaluates the suitability of the study area for particular crops. According to the square-root method, the area can be recommended as marginally suitable for cultivation of wheat, barley, alfalfa and safflower and is expected to yield about 40–65% of optimal production.

Fruit plants in Kediri Regency are classified as having good economic potential, one of which is pineapple. Pineapple plants in Kediri Regency have differences in productivity in each sub-district. The results of interviews with local farmers indicated that the Supiturung Micro Watersheds in Plosoklaten District had low pineapple productivity and were not yet optimal. Therefore, this study aimed to determine the factors causing differences and less optimal productivity of pineapples in the Supiturung Micro Watersheds and analyze the land suitability assessment of pineapple plants in the region. This study used a survey method with a physiographic approach to 10 Land Map Units (LMU) and determined 20 observation points as representatives. Data analysis was performed through correlation and multiple regression tests with the stepwise method to determine the land characteristics that most significantly affected pineapple productivity. Modification of the suitability class and modification of the criteria was carried out utilizing boundary line analysis, with class boundaries according to FAO (1976), namely class S1 (80-100%), S2 (60-80%), S3 (40-60%), and N (<40%) of the potential productivity. The land suitability evaluation results of pineapple plants in the Supiturung Micro Watersheds were included in land suitability classes S2, S3, and N. Based on the stepwise method analysis, the texture is a significant characteristic affecting the productivity of pineapples (p <0.05) with a correlation coefficient value of 0.838. The modification of land suitability criteria with boundary line analysis resulted in changes in one land characteristic, namely soil texture S2, S3, and N. Initially, the rough class included in the N class was changed to S2 level along with the slightly rough level.
