Abstract Background Assessment of suitable lands for irrigation is indispensable to plan and implement different programs in a cost-effective approach for sustainable land use planning and efficient utilization of the land. Hence selecting proper land use based on land suitability evaluation will enhance the productivity per unit area and ensures the sustainable use of land resources. Therefore, the research was designed to evaluate the suitability of the soil properties of Zamra irrigation scheme for irrigation purposes. Method For this study about 195.16 ha of land were evaluated for irrigation suitablity. Four soil profile pits were opened in the representative site of the scheme based on slope, texture, soil color and soil depth. Soil samples were collected from the soil mapping units for analysis of texture, electrical conductivity, and calcium carbonate content, whereas slope, drainage and soil depth were directly measured at the field. The evaluation was carried out using a parametric evaluation method. Results The results of the study revealed that four types of soils were identified namely, Rehodic Nitisol(eutric), Haplic Regosol (eutric) Eutric Regosol, Leptic Regosol (eutric, loamic), and Vertic Cambisol (Hypereutric). The soil texture consists of sandy loam and sandy clay loam at the surface and subsurface soil and the soil depth of study area varied from shallow to very deep. The soil of the scheme was free from salinity and the status of calcium carbonate was at a low level. The slope of the study area was ranged from flat (0–3%) to slopping (8–15%). Generally, 80.64 ha (41.32%) of the scheme was moderately suitable whereas 71.68 ha (36.73%) of the land was marginally suitable for irrigation. Due to major limiting factors of soil depth and slope about 42.84 ha of the land (21.95%) were not currently suitable for irrigation. Conclusion In the study area, the major limitations were slope and soil depth. Therefore, to increase production and productivity of the scheme, land improvement operations are suggested.

A reconnaissance soil survey was undertaken at 1:50, 000 scale to characterize and evaluate the land resources of Bhilwara district in Rajasthan for land use planning. Based on landforms seven typifying pedons along the toposequence were studied for their soil-site and physico-chemical characteristics in eastern plain. The study indicates that the soils of steeply sloping hilly terrain were very shallow, excessively drained, dark brown, sandy loam in texture with fine, weak sub-angular blocky structure. The soils of very gently sloping plain and nearly level plain are deep to very deep, imperfectly drained to well drained, olive brown to dark brown soils associated with higher water content at -33 and -1500 kPa and the organic carbon content was higher in the surface soils compared to subsurface and it decreased with depth. The calcium carbonate content ranged from 1.0 to 36.5 percent and the calcium carbonate content increased with depth. The soils of the hilly terrain (P1) and undulating pediment (P2) have been classified as Lithic Ustorthents and Lithic Haplustepts, respectively. Soils of the intervening valley (P3), undulating plain (P4) and gently sloping plain (P5) categorized as Typic Haplustepts, whereas the soils occurring on the very gently sloping plains (P6) were classified as Vertic Haplustepts. The soils formed on nearly level plain have been classified as Sodic Haplusterts (P7). The soils are grouped under IIes, IIIs, IVes and Ves land capability sub-classes and 2s, 3s, 3st, 3sd, 4st and 5st land irrigability sub-classes. The land suitability for major crops growing in the region indicated that the soils of the hilly terrain (P1) and undulating pediment (P2) are not suitable for most of the crops due to their very severe limitations of slope, erosion and soil depth. The soils of the intervening valley (P3) were moderately suitable for maize and sorghum and marginally suitable for wheat, cotton and mustard. Soils of undulating plain (P4) were highly suitable for maize, sorghum, wheat and moderately suitable for groundnut, cotton and gram. Soils of the gently sloping plains (P5) were highly suitable for sorghum; moderately suitable for maize, wheat, cotton and mustard; and marginally suitable for groundnut and gram. Soils of the very gently sloping plain (P6) were moderately suitable for sorghum and marginally suitable for maize, wheat, cotton and unsuitable for groundnut and gram. Soils of the nearly level plains were moderate to marginally suitable for other crops and unsuitable for groundnut and gram (P7).

Uganda Government embarked on promoting sedentary agriculture in Karamoja agro-pastoral semi-arid livelihood zone, which experience rapid environmental and high soil quality (SQ) decline. However, studies on sedentary agriculture’s impact on soil quality using farmer’s knowledge is limited. Consequently, a survey was carried out in Karamoja (Iriiri, Matany Sub-counties of Napak of districts and Rengen sub-county of Kotido) to determine the soil quality indicator parameters based on the farmers knowledge in order to build a local soil knowledge data base to better inform sustainable land use strategies. Using a semi-structured questionnaire, forty indigenous farmers per sub-county, were interviewed between August and September, 2015. The study took into account the social demographic characteristics of the people, farming enterprises, methods of crops production, crops yields trends, causes of the perceived yields trends and soil quality indicators. Prospects of developing Karamoja indigenous knowledge data base lies in visible feature that predict soil quality. Farmers used 36 parameters to determine SQ. The parameters were clustered into five categories; soil, crop, biological, environmental and management each category contributing to 42, 19,14,8 and 17% of the total indicators, respectively. The relationship between age group and the perceived indicators of soil fertility was statistically significant (p-value = 0.045) with the majority stating that they use either soil colour, soil depth or soil texture to express the fertility of soil. The farmer’s soil quality indicators assessed in this study, is important in establishing indigenous-scientific hybrid knowledge data base to enhance soil fertility maintenance and better inform policy makers and other stakeholders on development of sustainable land use strategies.

The objective of this research was to compare different irrigation methods based on a parametric evaluation system in an area of 16,350 ha in the Albaji Plain of the Khuzestan Province, in the southwest of Iran. The soil properties of the study area such as texture, depth, electrical conductivity, drainage, calcium carbonate content and slope were derived from a semi-detailed soil study carried out on the Albaji Plain on a scale of 1:20,000. After the soil properties were analyzed and evaluated, suitability maps were generated for surface, sprinkler and drip irrigation methods using a geographic information system (GIS). The results demonstrated that by applying sprinkler irrigation instead of surface and drip irrigation methods, the land suitability of 14,530 ha (88.87%) of the Albaji Plain could be improved substantially. However, the main limiting factors in using surface and sprinkler irrigation methods in this area were heavy soil texture, drainage and salinity, and the main limiting factors in using drip irrigation methods were heavy soil texture, calcium carbonate and salinity.

The soils and lands developed under sub-humid sub-tropical climate of Shiwalik foot hills of Himachal Pradesh were evaluated for their productivity and potentiality under different land uses viz. agriculture, pastures and forest/tree crops and suitability for sustained irrigation. The actual productivity of these soils for agriculture was rated extremely poor to nil, poor and average comprising 80.4, 11.3 and 4.4% of total geographical area (TGA) of the watershed, respectively. The corresponding productivity for pastures was 12.0, 51.2 and 33% of TGA. The actual productivity of all these lands for forest/tree land use was found to be extremely poor to nil. The potential productivity for agriculture was in poor, average, good and excellent classes comprising 64.4, 10.5, 12.7 and 8.6% of TGA, respectively. Whereas, it was found to be average, good and excellent for pastures in 39.4, 48.2 and 8.6% of TGA, respectively. For forest/tree land use, the potential productivity was found to be extremely poor to nil for majority of the soils comprising 74% of TGA. Other classesviz. poor and average covered only 14.7 and 7.5% of TGA, respectively. Thus, productivity of most of the soils could be increased to a greatextent by applying improvement measures to overcome the identified constraints as indicated by their potential productivity classes.Based on characteristics pertaining to soil, topography, drainage conditions and cost of land development these lands were classified into four irrigability sub-classes (3s, 4ts, 5ts and 6ts) according to the kind and degree of limitations for sustained use under irrigation. The respective classes covered 115.71, 105.2, 380.45 and 797.29 ha comprising 8.0, 7.2, 26.2 and 54.8% of TGA, there being no class 1 or 2 irrigable land. Topography, shallow soil depth, coarse soil texture, high permeability and low available water capacity are the main limiting factors identified those may be manipulated suitably to increase production potential of these lands.

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.

Although the criteria for defining erosion tolerance are well established, the limits generally used are not consistent with natural, economical and technological conditions. Rates greater than soil formation can be accepted only until a minimum of soil depth is reached, provided that they are not associated with environmental hazard or productivity losses. A sequence of equations is presented to calculate erosion tolerance rates through time. The selection of equation parameters permits the definition of erosion tolerance rates in agreement with environmental, social and technical needs. The soil depth change that is related to irreversible soil degradation can be calculated. The definition of soil erosion tolerance according to these equations can be used as a guideline for sustainable land use planning and is compatible with expert systems.

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.
