Abstract

Agricultural land suitability evaluation is a good way to distinguish soil suitability in order to improve the soils by addressing major limitations. This study investigated the influence of soil factors variability on the suitability of 12 Mediterranean crops in southern Spain. To represent the variability in elevation, lithology, and soil, two latitudinal and longitudinal soil transects (TA and TB) were considered and sampled in 63 representative points at regular 4. km intervals. This research also aimed to determine how to maximize soil potential by improving limiting factors as drainage, carbonate content, salinity, and sodium saturation. Soil suitability evaluation ranged between optimum and not suitable classes along TA and TB. The decrease in the severity of soil limiting factors in the improved scenario leads to an increase in soil suitability for the 12 crops along TA and TB transects, except in segments with shallow soils and very coarse texture. Soil evaluation and spatial analyses of soil suitability for the 12 crops under current situation and improved scenario, including optimum and not suitable soils, are helpful to achieve a sustainable land management in the studied area. The improvement of soil limitation it could be as adaptation strategies for the long term of environmental changes as climate changes, this work has a real impact, which means the results valuable and easy to grasp for the decision makers.
