Agricultural land use planning should always be guided by a reliable tool to ensure effective decision making in the allocation of land use and activities. The primary aim of this study is to develop a user friendly system on a spatial basis for agricultural land suitability evaluation of four groups of agriculture commodities, including food crops, horticultural crops, perennial (plantation) crops, grazing, and tambak (fish ponds) to guide land use planning. The procedure used is as follows: (i) conducting soil survey based on generated land mapping units; (ii) developing soil database in GIS; and (iii) designing a user friendly system. The data bases of the study were derived from satellite imagery, digital topographic map, soil characteristics at reconnaissance scale, as well as climate data. Land suitability evaluation in this study uses the FAO method. The study produces a spatial based decision support tool called SUFIG-Wilkom that can give decision makers sets of information interactively for land use allocation purposes.This user friendly system is also amenable to various operations in a vector GIS, so that the system may accommodate possible additional assessment of other land use types.

K Factor

Soil erodibility K factor is an important parameter for evaluating soil erosion vulnerability and is required for soil erosion prediction models. It is also necessary for soil and water conservation management. In this study, we investigated the spatial variability characteristics of soil erodibility K factor in a watershed (Changyan watershed with an area of 8.59 km2) of Enshi, southwest of Hubei, China, and evaluated its influencing factors. The soil K values were determined by the EPIC model using the soil survey data across the watershed. Spatial K value prediction was conducted by regression-kriging using geographic data. We also assessed the effects of soil type, land use, and topography on the K value variations. The results showed that soil erodibility K values varied between 0.039–0.052 t·hm2·h/(hm2·MJ·mm) in the watershed with a block-like structure of spatial distribution. The soil erodibility, soil texture, and organic matter content all showed positive spatial autocorrelation. The spatial variability of the K value was related to soil type, land use, and topography. The calcareous soil had the greatest K value on average, followed by the paddy soil, the yellow-brown soil (an alfisol), the purple soil (an inceptisol), and the fluvo-aquic soil (an entisol). The soil K factor showed a negative correlation with the sand content but was positively related to soil silt and clay contents. Forest soils had a greater ability to resist to erosion compared to the cultivated soils. The soil K values increased with increasing slope and showed a decreasing trend with increasing altitude.

The soil family was used to describe soil map units in an intermediate level survey of British Columbia. The main obstacle to its application was determination of soil climate. Soil climate (soil temperature classes and soil moisture subclasses) was derived from atmospheric climate data. It was then related to climax forest vegetation which was used to locate map unit boundaries. By linking biological characteristics to the soil survey, interpretations for wildlife and forestry were enhanced. At the level in which the survey was conducted, the soil family usefully reflected the soil variation in the landscape while providing ample information for most land use interpretations.

AbstractThe ever increasing pressure for infra-structural development in the UK heightens the conflict between the different land use demands placed on an area. This is reflected in the need for planning authorities to assess the relative suitability of potential land uses. Such assessments are important in guiding urban development away from good quality agricultural land. It is manifest that such planning decisions should be made on the basis of a comprehensive review of all relevant factors, and in particular, this includes the pedological soil conditions with their controlling influence on the ability of the land to support different land uses.Past pedological studies have tended to concentrate on the evaluation of land suitability for agricultural uses. However, such studies are also of value when assessing the suitability of other potential uses including, forestry, recreational uses, natural resources or general infrastructure development.In site investigations for infrastructure or resource development pedological studies have a role to play both at the feasibility and detailed investigation stages. During a feasibility study, particularly when used in conjunction with a programme of geotechnical mapping, a pedological approach to the examination of point samples can be an important aid in the determination of the areal extent of engineering soil units. In detailed investigations pedological assessments during pitting operations can determine such items as the depth of topsoil to be removed and stored during stripping, if a profile has developed through in-situ weathering of bedrock or a derived superifical cover and will assist in the identification of poor drainage areasIn this paper examples are presented of soil surveys used to assess the suitability of areas for recreational use, urban development and forestry. Also, by comparing the approaches to soil description contained within BS 5930, Code of Practice for Site Investigations (British Standards Institution 1981), and the Soil Survey Field Handbook (Hodgson 1974), some recommendations are made for adopting pedological description techniques in geotechnical site investigations.

Abstract. Hydropedology is well positioned to address contemporary issues resulting from climate change. We propose a six-step process by which digital, field-scale maps will be produced to show where climate change impacts will be greatest for two land uses: a) home sites using septic systems, and b) wetlands. State and federal laws have defined critical water table levels that can be used to determine where septic systems will function well or fail, and where wetlands are likely to occur. Hydrologic models along with historic rainfall and temperature data can be used to compute long records of water table data. However, it is difficult to extrapolate such data across land regions, because too little work has been done to test different ways for doing this reliably. The modeled water table data can be used to define soil drainage classes for individual mapping units, and the drainage classes used to extrapolate the data regionally using existing digital soil survey maps. Estimates of changes in precipitation and temperature can also be input into the models to compute changes to water table levels and drainage classes. To do this effectively, more work needs to be done on developing daily climate files from the monthly climate change predictions. Technology currently exists to use the NRCS Soil Survey Geographic (SSURGO) Database with hydrologic model predictions to develop maps within a GIS that show climate change impacts on septic system performance and wetland boundaries. By using these maps, planners will have the option to scale back development in sensitive areas, or simply monitor the water quality of these areas for pathogenic organisms. The calibrated models and prediction maps should be useful throughout the Coastal Plain region. Similar work for other climate-change and land-use issues can be a valuable contribution from hydropedologists.

SummaryWe have analyzed the loss of agricultural land in a case study of the community Eggelsberg in the Innviertel in Upper Austria. The trigger for the project was the attribution of Austria as Europe’s leader in soil sealing. We compared the results of the Austrian agricultural soil survey of the 1970s with the actual land use and quantified the land use change. Within half a century, 15% of the agricultural area was converted to settlement area or to other forms of infrastructure. According to the original soil assessment, 96 ha of high-quality cropland, 1,220 ha of medium-quality cropland, 121 ha of low-quality cropland, and 409 ha of grassland were converted. The forest cover remained stable. The highest share of soil sealing was owed to the expansion of the settlement area and the construction of a successful enterprise. Minor contributions were expansions of farm buildings. The loss of agricultural land was reasonable and reflected the needs of the local population. A special protection status because of the future relevance of the agricultural land was not communicated to land managers and is not reflected in the market prices of agricultural products. The relevance of the agricultural land beyond the regional level is not fully recognized.
