We sampled a total of four sites and four soil characteristics were selected to review some results and how to calculate the weight of these characteristics. This method of weighing soil characteristics can used in some soil surveys and classification studies, especially with regard to land evaluation and degradation studies, as well as characteristic variations, especially the delineation of soil horizons are affected by lateral and vertical variation in soil properties, which are texture, gypsum, lime, ECe, ESP, and CEC as their importance increases at the soil surface and decreases with depth as it is related to plant growth and nutrient processing, and thus it was given more weight in the upper horizons and less weight with depth, as well as studies that are concerned with finding a single value representing the pedon and not depending on the value of the characteristic in the surface horizon only. This suggested table helps in making the calculations easier and eliminates the use of the scientific calculator by converting the results of the equations in the form of a table that contains all the possibilities of variation in the thickness of the horizons. These values have been set to more than the effective depth of the soil, which is adopted within the first meter. The table has been designed for a depth of two meters in case the study requires more depths.
