“…Therefore, soils of Toshka were studied by different land evaluation systems such as Storie index, ASLE program, MicroLEIS (Abd El-Aziz, 2018 andSalah, 2018)). These studies were showed that most common limitation factors for crop production in Toshka area are the shallow soil depth, highcontent of gravel, soil texture, low soil fertility and soil pH (Abbas et al, 2010;Fayed et al, 2010;Sherif, 2016;Aldabaa et al, 2018;Salah, 2018 andMohamed et al, 2019). However, the conventional assessment of land suitability is based on evaluating the sampled sites without taking in consideration the unsampled ones.…”

D UE TO the rapid growth of population in Egypt and the scarcity of land and water resources, the effective management of these resourceshas become a very urgent necessity to achieve the sustainable agricultural development. Consequently, land suitability assessment is an important tool to manage these resources appropriately. The objective of this study was to use geostatistical approach and geographical information system (GIS) to evaluate the land suitability for some essential cropsin Toshka region, Egypt.Soil parameters such as gravel content, soil texture, pH, EC, CaCO 3 , ESP and CEC were determined, at 1.0 km grid soil sites. Afterward, the geostatistics approach using ordinary kriging interpolation and semivariogram were applied to produce a spatialized and detailed map for each soil parameter. Gaussian, Exponential and Spherical geostatistical models were used to define the spatial variability of soil properties based on RMS, MSE and RMSSE. Also, based on Storie equation the kriged interpolated maps were incorporated in the model builder within GIS environment to achieve the land suitability assessment. The results illustrated that, most of the investigated area are unsuitable (N) for vegetable crops. However, the study area is more promising for field crops where 42.71 % and 11.20 % of the total area are moderately suitable (S2) for barely and alfalfa crops respectively. Furthermore, the results confirmed that, some of orchids crops are very suitable for the study area whereas 6.80 % and 37.81 % of the studied area are highly suitable (S1) and moderately suitable (S2) for olives respectively. On the other hand, the results revealed that the results indicated that, the most limiting factor in the investigated area are EC, pH, calcium carbonate content, CEC and soil texture. Finally, it can be concluded that the geostatistical approach and GIS are powerful and effective tools for land suitability studies and consequently for sustainable planning of land use.

“…However, calcium carbonate presence vertically rarely affect the movement of water, but may prevent the roots movement and spread. According to FAO Calcium Carbonate Index (Sideruis, 1984 andFAO,1985) to give relative weights to each category; This factor's values were divided into five different categories and reclassified, as shown in the table (6) and figure (9). Gypsum is agricultural useful; It improves the state of soil construction, as a source of calcium, plant's nutrient and replaces mutual sodium in soils, so, it prevent soil degradation.…”

Soil capability always related to soil quality, which directly affect productivity, environmental factors, land use/land cover, and bio-activities. Monitoring of soil capability parameters will help to simplify and explain some impacts of climate effect on hyper arid condition and the responses required for such difficult agricultural adaptation. This paper presented using geographic information system, GNSS and remote sensing techniques "geomatics" to manage and update soil spatial datasets, furthermore, spatial-climate monitoring for soil characteristics and distribution. Assessing land types and identifying degraded spots with soil problems such as salty, alkaline or other productive capability. Adding an interpolation methods for generalizing samples results for study area. In the current research, a spatial-climate model for soil capability was built to evaluate soil capability based on; chemical, physical and biological soil characteristics. The results of the spatial model were correlated with both land capabilities and climate of the study area. Nonetheless, this model proposed for decision-makers tool for soil capability classification under similar conditions.
