Soil samples were collected before and after burning the plant residues and the total number of bacteria and fungi and estimating the enzymatic activity of cellulase and phosphatase and some soil properties such as pH, Electrical conductivity, Water retention capacity, organic carbon and the total phosphorous, The results showed a decrease in the rate of the total number of aerobic bacteria (5.38 × 104) colony-forming unit(CFU) / g of soil, the average total number of fungi (4.31 × 106) CFU / g, the rate of enzymatic activity is(2.28) units / ml for cellulase and(11.67) units / ml for phosphatase after burning the plant residues compared to the non-burned soil samples, Where the rate of total number of aerobic bacteria (5.85 × 104) CFU / g and the rate of the total number of fungi (4.75 × 106) CFU / g of soil and the rate of enzymatic activity is(3.65) units / ml for cellulase and (16.22) units / ml for phosphatase, the results of the study also showed a change In some soil physiochemical properties as a result of burning plant residues, the average values of the pH, electrical conductivity, and the rate of total phosphorus concentration, soil water retention capacity increased, but the organic carbon concentrations decreased compared to the non-burned soil samples.
