Both soils are alkaline soils [ 33 ], with mean pH values ranging from 8.21 to 8.29, and the pH level of arable soils is significantly higher than that of saline soils ( p < 0.01); the mean values of the TS content of the two types showed a highly significant difference ( p < 0.01), with the TS content of the OY group being (0.58 ± 0.04) g/kg, which is a mildly saline soil; from the nutrient results, it can be seen that AP, AK, TN, and SOM had the same trend, all of which showed that their contents were significantly higher in arable soils than in saline soils ( p < 0.01). 3.1.2.
