Al-Ahsa soils are underlain by an impermeable marl layer (mixtures of clay and calcium carbonate) at zero to 2 m depth below the ground surface. Excess irrigation water accumulates on top of this layer, forming a shallow water table beneath the soils of the Al-Ahsa Oasis. The water table depth is affected by varying depths to the marl layer, the soil texture, and depth and spacing between field drainage canals [23]. The irrigated arid zone of Al-Ahsa oasis faces twin problems of water scarcity and waterlogging accompanied by salinity. For more details about the studies related to the soil of Al Hassa, refer to [24; 25; 26]. [PERSON] [27] investigated the extent of soil salinity, irrigation water quality, and the relationship with the growth of vegetation, employing NDVI derived from Landsat satellite imagery. [PERSON] and [PERSON] [28] reported that salt-affected soils in Al-Ahsa region represent as much as 20 % of the total area. [PERSON] [21] studied the degraded agricultural soils at Al-Ahsa Oasis and reported that the decline in the soil productivity distinguished the soil degradation at Al-Ahsa oasis. He attributed that to human activities and the marginal climatic conditions, which are considered the most important sources of soil degradation. The soil chemical properties exhibited slightly alkaline pH values, extending between 7.33 and 7.86, while the soil salinity data, as EC (electrical conductivity) values, varied across the Al-Ahsa Oasis. He found several values that exceeded 400 mS/m (i.e., the minimum value of saline soils), reaching 7.80 dS m\({}^{-1}\), implying the persistence of soil salinity conditions (i.e., saline soil) in the Oasis's agricultural soils. It was also noticed that the soil EC values increased with increasing soil depths, signifying the inefficient drainage systems and, hence, salinization of the soil profile in the Oasis [21]. Inland Sabkhas in Al-Ahsa area are salt-affected intermediate to dark brown soils found in relatively low relief areas. Sabkha in Al Hassa exists in very low relief areas, which are saturated with water (where groundwater rose and pushed salt to the surface).and may even have surface water [27]. Al-Ahsa drainage water is collected by earthen lateral open canals having depths of about 1 m. The collected drainage water in the eastern part of Al-Ahsa oasis flows from the lateral's canals to three sub-main drainage canals, which are connected to the main drainage canal D2 as shown in Figure 2. The collected drainage water in this drainage flows towards an evaporation lake in Al Asfar 13 km to the east of the Oasis, while the drainage water in the northern sector flows from the lateral to the sub-main drainage canals that were connected to the main drainage canal D1. The drainage water in D1 flows towards an evaporation lake in Al Uyoun (see Figure 2). The collected water in both lakes remains in the winter season to be a source for cattle to drink, as well for shallow aquifer recharge. From December until April, the agricultural drainage water overflows from Al Uyoun lake through small waterways into the Arabian Gulf [23]. For more details about the hydrogeology and the hydrochemical characterization of the groundwater of the Al-Ahsa area, refer to [19; 27; 29; 30; 31; 32]. Soil surveys require quick and, when possible, nondisturbing estimations of numerous soil properties, such as salinity, texture, stone content, groundwater depth, and horizon sequence in soil profiles; however, conducting soil measurements with a high sampling density is costly and time-consuming. Conventional methods of soil analysis mostly require disturbing soil, removing soil samples, and analyzing them in a laboratory. So, the traditional methods used to acquire soil information involve intensive field surveys and laboratory analyses. As a consequence, only limited amounts of data are collected.
