Abstract
Biological reclamation is considered one of the effective approaches in improving the chemical quality of soil, especially in arid and semi-arid regions. This study was conducted in 1403 with the aim of investigating the effect of biological reclamation operations on the concentration of nitrogen, phosphorus and potassium in the artificial afforestation soil of the Tal Siah area located in Jiroft County, Kerman Province. Soil sampling was carried out from the reclaimed and control areas at two depths and the data were analyzed using the ANOVA statistical test. The results showed that the phosphorus concentration in the reclaimed area at a depth of 0-15 cm was 8.3645 mg/kg and at a depth of 15-30 cm was 8.3434 mg/kg, while these values in the control area were 3.9080 and 2.46 mg/kg, respectively. The amount of nitrogen in the reclaimed area was estimated to be 0.0218 and 0.0148 percent for the two depths, respectively, while it decreased to 0.0055 and 0.0037 percent in the control area. Potassium at a depth of 0-15 cm in the reclaimed area was 3.0526 mg and 3.9826 mg in the control, while at a depth of 15-30 cm, its amount was recorded as 2.9653 mg in the reclaimed area and 4.0173 mg in the control. These findings indicate a positive effect of biological reclamation operations on soil phosphorus and nitrogen, although its effect on potassium was dependent on depth and location.
