In order to study the effect of mineral and organic fertilizers and humic acid on the percentage of total and active carbonates in and outside the rhizosphere and planted with two plants (Maize and Mung bean) and for the flowering and full maturity stages. The experiment was carried out according to a randomized complete block design (R.C.B.D), where the number of experiment treatments was (4), including the comparison treatment, and with three replications for each treatment, and these treatments were randomly distributed to the experimental units, so the number of units became (12) experimental units for each plant (maize and Mung bean), meaning that the total units became (24) experimental units, the experiment’s treatments included the mineral fertilizer consisting of fertilizer (Urea+DAP) at one level and according to the fertilizer recommendation for each plant and symbolized by the symbol (M) and the organic fertilization was the addition of (poultry waste) at one level (10) tons ha-1 and symbolized by the symbol (O), and liquid humic acid was added at one level and according to the fertilizer recommendation and symbolized by the symbol (H) and the results of the study were as follows: The treatment of adding humic acid in soil planted with maize in the rhizosphere and outside the rhizosphere at the flowering stage recorded the lowest percentage of total carbonate in the soil amounted to (28.67 and 30.62%), respectively, compared to the comparison treatment, which recorded the highest percentage of total carbonate amounted to (32.17 and 33.62%) respectively, as for the stage of full maturity, the treatment of adding organic fertilizer was the one that recorded the lowest percentage of total carbons, which amounted to (29.61 and 32.00%) respectively, compared to the comparison treatment, which recorded (32.62 and 35.17%) respectively. The treatment of adding humic when added to soil planted with maize achieved a significant decrease in the percentage of active carbonates in and outside layers of the rhizosphere in the flowering stage, as it recorded (4.75 and 5.37%) respectively compared to the comparison treatment, which recorded the lowest value of (7.25 and 7.87%) respectively, while in the stage of full maturity, the treatment of adding humic acid achieved a significant decrease, as it recorded (2.08 and 2.67%) respectively, compared to the comparison treatment, which recorded (6.12 and 6.50%) respectively. The treatment of adding humic acid to a
