The mechanistic cropping systems model PERFECT was validated for six different soils and used as a tool to evalute land suitability of wheat cropping in the Maranoa, a marginal cropping area of Queensland. Using 100 years of historic climate data from the area, and crop, soil and management parameters, simulations provided an objective insight into the key interactions of the cropping system. Current methods of land suitability evaluation are qualitative and rely on the experience of the land resource surveyor and local precedent. Consequently, where local precedent is lacking, as in marginal areas, current methods are considered less reliable and quantiative data from simulation studies will be useful. Using this process, the significance of key components of the systems (climate, plant available water capacity, soil nitrate and soil loss hazard) were quantified. These quantitative data were used to establish critical values for diagnostic attributes for land suitability evaluation in the Maranoa. The role for this approach as a tool in quantitative land evaluation is discussed.

Significant Difference

Land evaluation for irrigation is the process of predicting land use potential on the basis of soil attributes. The Food and Agriculture Organization (FAO) framework for land suitability evaluation is the most commonly used and is based on the biophysical properties of lands. The FAO framework method for land suitability application Boolean approach that has been criticized by some researchers. Because the Boolean representations ignore the continuous nature of soil and uncertainties in measurement and also its inability for overcoming problems related to vagueness in definition and other uncertainties, fuzzy set methodologies have been proposed. In the present study, the qualitative land suitability evaluation for sprinkler irrigation using parametric-based FAO learning and fuzzy inference system was carried out in an area of 5175 ha in Northwest Iran. By overlaying the layers (soil texture, soil depth, lime, electric conductivity, drainage, and slope) and use of spatial data modeler in ArcGIS 9.3, land evaluation maps for sprinkler irrigation were provided for the area under study. Results showed that based on the parametric approach, 1598 ha of the study area were classified as highly suitable (S1 class) for sprinkler irrigation; the area of highly suitable lands in the parametric method was about five times the area of highly suitable lands obtained through the fuzzy method. In addition, the two methods were completely different in determining moderately suitable lands (S2). Accordingly, 787 ha in the area was moderately suitable using the parametric method, which was about two times that obtained through the fuzzy method. This showed the significant difference between two methods applied to evaluate the lands. Moreover, fuzzy approaches accommodate the continuous nature of some soil properties and produce more intuitive distributions of land suitability indexes.

Land Evaluation System using the modified Food and Agriculture Organization framework was carried out to assess the suitability of various important crops to Quingua soil series. Corresponding sound management interventions were then formulated over the identified production constraints. This was done to achieve a more productive and sustainable rice-based farming. The system generates a more specific land utilization type in which spatial and climatic variabilities are recognized.  The data used for land suitability evaluation was extracted from 2011-2012 cropping seasons. Analysis disclosed that Quingua series in Talavera and Sto. Domingo, Nueva Ecija, Philippines, representing irrigated and irrigation-supplemented lowlands, respectively, has high flexibility to growing various types of crops due to its favorable land attributes. Hence, crop intensification is highly recommended provided that minor limitations on soil organic matter, drainage, temperature, and seasonal flooding are offset. Multiple cropping system that involves off-season vegetable production and growing of cash or high-value crops in combination or rotation with rice dominates the farms’ landscape. This practice had generated varying levels of return on investment (ROI) from negative to more than 1000% as affected primarily by climate and farm management. Designing market-driven cropping systems under good management strategies can generate stable ROIs’ ten times higher than the production cost, hence, a more productive and profitable enterprise. Furthermore, soils of the same soil series exhibit similar characteristics or properties that require the same level of management in achieving the desired production output. Thus, information obtained from land suitability evaluation can serve as an effective tool for the government’s specific crop production program and agro-technology promotion.

AbstractLand suitability analysis is very important to assess and propose the most suitable land-use options. The reliability of land suitability evaluation is controlled by choosing the most limiting land characteristics and their ratings for the proposed land utilization types (LUTs). This study aims at examining the possibility of using current land use and farmers' knowledge as a starting point to suggest and/or modify land evaluation criteria, and to improve the land suitability evaluation process. The potential suitability of land for five LUTs (open range, improved range, rainfed barley, drip-irrigated vegetables and drip-irrigated trees) was evaluated near Al-Mafraq in Jordan using the maximum limitation method. The results indicated variable agreement levels between potential land suitability and current land use for different LUTs. Sixteen farms were selected to represent different cases of disagreement between potential suitability and current land use and were visited to explore the farmers' improved management practices adopted to overcome land-use limitations. Using proposed criteria, only 1% of the study area was highly suitable for drip irrigation, whereas most of the area was moderately or marginally suitable for other uses. This represents the conventional land evaluation procedures, which, in most cases, overlook the farmers' knowledge and practices that are adopted in a particular area to overcome biophysical limitations. The ratings for different land characteristics were modified based on comparisons with current land use, and by referring to farmers’ adopted management practices. Using modified criteria, the highly suitable area for drip-irrigated vegetables increased by 18% and the highly suitable area for drip-irrigated trees increased by 25%. The results emphasized that the consideration of the farmer's indigenous knowledge and current land use improve the land evaluation process, which leads to better utilization of limited land resources in fragile environments.

The Right

The suitability of the land resources in the watershed for various crops is necessary to choose the right crop and variety suitable for the area. In carrying out this assessment, the specific land requirements of a crop are compared with the characteristics of land resource mapped in the sub- watershed with this objective  investigation was carried to assess land suitability for growing horticultural crops in Kanamadi South sub-watershed of Vijayapura district of Karnataka. The soil survey was conducted using 1:7920 scale, LISS IV satellite imagery.  The soils were shallow to deep with clay loam to clay in texture. The soils were low in nitrogen and organic carbon, low to medium in phosphorus and sulphur, medium to high in potassium. Iron, copper, zinc and manganese were sufficient. Land suitability evaluation revealed that soils were moderately suitable for growing fruits such as guava (73.75% TGA), pomegranate (70.73% TGA), sapota (85.65% TGA). In case of flowers, major part of the study area was marginally suitable for crops such asrose (65.26% TGA) and jasmine (91.72% TGA). Around 11.55 per cent of the area was evaluated as unsuitable for growing fruit crops. The consideration of depth and nutrient status of soil in sub-watershed area is ideal to grow the horticultural crops like fruit crops with soil conservation measures to obtain food sustainability and nutrition level of people living the study area.

The Impact

Abstract This study investigated the impact of soil temperature and soil moisture on the virulence To protect soil resources and also to achieve optimal crop production, it is essential to dedicate the most suitable land to a specific land use. Achieving this goal is possible through land use planning in conjunction with land evaluation. In this study a land suitability evaluation was carried out for wheat (Triticum aestivum) cultivation, and was performed in the Bastam region located in the north east of Iran. 104 soil profiles were sampled and 11 land units were separated. In order to find out the most correct method of physical land suitability evaluation, three methods of combining soil criteria for soil index calculation for wheat production were tested. These methods are based on parametric and maximum limitation approaches, and the results of each method were compared with the observed yield. Ultimately, the maximum limitation method was found to be the best method and was used for classification of the suitability of the study area lands for wheat cultivation. The varying results of applying different ways of evaluation in this study indicate that the accuracy of the method of land evaluation adopted should be checked before using the results for any purposes.
