| Flood spreading is one of the most important soil protection and improvement measures, which both prevent flood waste and help fight desertification. This research aimed to investigate the effect of flood spreading and plant type on the activity of some physicochemical and biological properties of the soil in pasture fields with and without flood spreading in the Garbayegan, Fasa in 2019-2020. Soil sampling was carried out in spring and autumn to a depth of 20 cm in three repetitions around the rhizosphere of plants and modified according to the materials and methods section. The averages were compared with Duncan's test at the level of 1.5% and using R software. The results showed that the amount of usable phosphorus and potassium in the flood spreading conditions and the control area was without significant difference, but the amount of carbon and nitrogen in all the studied species in the flood spreading area was significantly different. It was more significant than the witness was. However, the amount of respiration in the flood spreading area was the highest, while the respiration and microbial biomass in the control area showed the highest amount. However, the amount of basal heat and microbial biomass in flood spreading areas showed a lower amount, which can be the result of the low amount of organic matter in the soil as a result of excessive livestock grazing in these areas. Finally, it is recommended to implement flood-spreading projects in arid and semi-arid areas to increase the productivity of soil characteristics. |
