Evaluating land suitability of a given watershed is vital to predict potential and limitation of the land for surface irrigation. The present study was evaluated the suitability of Gudina Wacho watershed for surface irrigation development using parametric evaluation approach. The watershed was classified in to four lands mapping units, based on three soil profile pits were opened at each land mapping unit. Soil samples from each profile pit have been taken to analyze each selected soil physical and chemical properties. Slop analysis of the watershed was computed from the DEM using GIS technique. Results of the land suitability evaluation for surface irrigation showed that, a total area of 3064 ha (72.6%) was slightly suitable (S3) and area of 1154 ha (27.4%) was currently not suitable (N1). The limiting factors were slop, soil texture and drainage. For all land mapping units, chemical soil parameters such as CaCO3, ECe and pH, and the physical parameter (soil depth) were not limiting factors for surface irrigation in the study watershed. Therefore, the area is potential for irrigation production with some limitations and under proper management it can benefit the local community to meet the food demand. In order to sustainably develop the area for irrigation development; land leveling operation or soil conservation work has to be incorporated to break surface slope and to make it suitable for surface irrigation.

Cocoa Production

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.

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.

Square Root Method

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.

<p>The conventional Boolean logic models of land suitability assessment disregard the continuity concepts of the soil and landscape which might cause inaccurate evaluation and classification. To overcome this uncertainty and consequent constraints, the fuzzy set theories were introduced. Therefore, the current study was undertaken to estimate the optimum soil depth that is used in land suitability evaluation for irrigated rice through the fuzzy sets theory and analytic hierarchy process (fuzzy AHP) in Guilan Province, Iran. The square root and quantitative land suitability evaluation methods were employed to calculate traditional land suitability indices (for depths, 0-25, 0-50, 0-75, and 0-100 cm). Also, fuzzy and fuzzy AHP methods were used to explore new land indices. The Sarma similarity indices were used to compare the results of traditional and fuzzy methods for different soil depths. The results showed that the compatibility percentage between the representative pedons (0-100 cm) and the findings of this research (0-50 and 0-75 cm) were remarkable. Furthermore, the highest compatibility percentage of land suitability class was related to the comparison of these two former depths and 0 to 100 cm depths in each of the two used fuzzy methods. Besides, except for 0-25 cm depths, actual yield revealed a significant and positive correlation with the rest three soil pedon depths. These findings show that considering 0 to 50 cm soil depth might be a relevant alternative as the optimal depth to evaluate land suitability for rice in paddy fields in the Guilan rice-growing area. </p>
