“…Using Sentinel 2 images leads to increased clarification details of landscape where the high and low lands, basin and wadis boundaries were identified [30,62,63]. The soils that are located in southern parts of the study area were classified as Lithic Torripsamments, whereas the soil profiles' depth is very shallow and this is considered as a main obstacle to soil capability and crop suitability [64,65]. On the contrary, the soil types Typic Torripsaments, Typic Torrifluvents and Typic Haplocalcids were allocated in the wadi, decantation basins and sand plain geomorphic units with deep soil The geomorphic units such as the plateau, escarpment and ridge were not considered in the suitability evaluation, which represents 28% of the total study area.…”

The development of the agricultural sector is considered the backbone of sustainable development in Egypt. While the developing countries of the world face many challenges regarding food security due to rapid population growth and limited agricultural resources, this study aimed to assess the soils of Sidi Barrani and Salloum using multivariate analysis to determine the land capability and crop suitability for potential alternative crop uses, based on using principal component analysis (PCA), agglomerative hierarchical cluster analysis (AHC) and the Almagra model of MicroLEIS. In total, 24 soil profiles were dug, to represent the geomorphic units of the study area, and the soil physicochemical parameters were analyzed in laboratory. The land capability assessment was classified into five significant classes (C1 to C5) based on AHC and PCA analyses. The class C1 represents the highest capable class while C5 is assigned to lowest class. The results indicated that about 7% of the total area was classified as highly capable land (C1), which is area characterized by high concentrations of macronutrients (N, P, K) and low soil salinity value. However, about 52% of the total area was assigned to moderately high class (C2), and 29% was allocated in moderate class (C3), whilst the remaining area (12%) was classified as the low (C4) and not capable (C5) classes, due to soil limitations such as shallow soil depth, high salinity, and increased erosion susceptibility. Moreover, the results of the Almagra soil suitability model for ten crops were described into four suitability classes, while about 37% of the study area was allocated in the highly suitable class (S2) for wheat, olive, alfalfa, sugar beet and fig. Furthermore, 13% of the area was categorized as highly suitable soil (S2) for citrus and peach. On the other hand, about 50% of the total area was assigned to the marginal class (S4) for most of the selected crops. Hence, the use of multivariate analysis, mapping land capability and modeling the soil suitability for diverse crops help the decision makers with regard to potential agricultural development.

“…Additionally, they applied a qualitative model for evaluating soil suitability to assist decision makers for sustainable agriculture planning and economic productivity of soil resources in Iran. While, in the north-western region of Libya, Reference [86] reported that the main limiting factors of soil suitability for wheat, maize, alfalfa, sunflower, soybean, potato, citrus, and olives crops were soil salinity, soil texture, alkaline pH, calcium carbonate, and soil depth. Their findings are consistent with this research's observations.…”

Assessment of Soil Suitability for Improvement of Soil Factors and Agricultural Management

The dramatic growth of the world’s population is increasing the pressure on natural resources, particularly on soil systems. At the same time, inappropriate agricultural practices are causing widespread soil degradation. Improved management of soil resources and identification of the potential agricultural capability of soils is therefore needed to prevent further land degradation, particularly in dryland areas such as Egypt. Here, we present a case study in the El-Fayoum depression (Northern Egypt) to model and map soil suitability for 12 typical Mediterranean crops. Two management scenarios were analyzed: the current situation (CS) and an optimal scenario (OS) of soil variables. The Almagra model was applied to estimate soil suitability under CS and OS. Management options based on the CS assessment were proposed to reduce some limiting factors: a fixed value of 2 dSm−1 for soil salinity and 5% for sodium saturation; these defined the OS. Under optimal management, the OS scenario showed potential, where a notable increase of the area covered by a high suitability class (around 80%) for annual and semi-annual crops was observed. There was also a marked increase (about 70% for CS and 50% for OS) for perennial crops shifting from the marginal to moderate soil suitability class. The results reveal the importance of proper management to massively alter soil suitability into better states in order to achieve sustainable land use in this fertile agro-ecosystem.

“…The fitness of land for a defined use is termed as land suitability (Shyju1 and Kumaraswamy, 2019). Land suitability assessment is defined as the process of land performance assessment to predict the potential land for crop production (FAO, 1976;FAO, 1978;Pan and Pan, 2012;Darwish and Abdel Kawy, 2014;Ahmed, 2016;AbdelRahman et al, 2016 andAbd El-Aziz, 2018), and identifying the main limiting factors for the agricultural production and enables decision makers to increase the land productivity (AbdelRahman et al, 2016). Assessment of land suitability potentials is an important step to detect the environmental limit for sustainable land management (SLM) (Zolekar and Bhagat, 2018).…”

The current study was carried out on the soils of Halaib and Shalatien to estimate their capability and suitability for growing some crops (maize, wheat, alfalfa, potato, sugar beet, citrus, peach and olive). The studied area lies between latitudes 22 ˚ 20 `10`` and 22 ˚ 45 ` 11.5`` N, and longitudes 35 ˚ 55 ` 4.4`` to 36 ˚ 21 ` 4.6`` E. For this purpose, 17 soil profiles were dag and collect of soil samples. The soils were classified as Typic Torrifluvents, Typic Torripsamments, Typic Torriorthents and Lithic AquiSalids. The geomorphologic units of Halaib and Shalatien region are divided into three groups: (1) Bahada Plains (alluvial fans and deltas, alluvial plains, wadis, sand sheets, sand dunes and plains with rock outcrops), (2) Coastal Forms (alkali flats), and (3) Faulted Mountains and Hills (mountains, mountain foot slopes, hills and hill foot slopes). The Automated Land Evaluation System program (ALES program) and Geographic Information System (GIS) were used to evaluate the land suitability in the studied area. Rock land and sand dunes occupied 57.68% of the total area. According to ALES program, the capability of the lands in the study area are grouped into four classes; Class (3) occupied 8.46% of the study area and represented by alluvial fans and deltas mapping units, Class (4) occupied 24.72% of the study area and included alluvial plains, wadis and sand sheets mapping units, Class (5) occupied 7.82% of the study area and included plain with rock outcrops and sand dunes mapping units and Class (6) occupied 1.16% of the study area and represented by only one soil map unit (Alkali flats). According to ALES program, the suitability of the study area classified into four classes: high suitability class (S2) occupying 16.39% of the study area, moderate suitability class (S3) occupying 13.27% of the study area, marginal suitability class (S4) occupying 8.26% of the study area, no suitability class (S5) occupying 3.23% of the study area. The main limitation factors for crop production in the studied area were soil texture, depth and salinity. These limitations are none permanent and can be improved through applied appropriate management practices.
