| The impact of cyanobacterial species (Nostoc lichenoides, Nostoc indistinguendun, Nostoc favosum, and their mixtures) on soil characteristics such as water holding capacity (WHC), aggregate size distribution (%) to calculate the mean weight diameter (MWD), organic carbon (OC), total nitrogen content, and total counts of cyanobacteria in sandy and clay loam soils. The results showed that, compared to the un-inoculated soil, inoculation of the soil with cyanobacteria and their mixtures enhanced the soil WHC, MWD, OC, and total nitrogen in both soil types. After 60 days of incubation, the cyanobacterial mixtures produced the best WHC% results. In the case of MWD, the results were more pronounced with cyanobacterial mixtures at 60 days compared with the control in both sandy and clay loam soils, respectively. The organic carbon content of soils increased with increasing incubation period, reaching the highest value in the two soil types at 60 days incubation period. Also, the inoculation with different cyanobacteria species significantly increased the total nitrogen contents of the two tested soils when the incubation period was increased, especially with a mixture of cyanobacteria. At the same time, the results of the total counts of cyanobacteria showed that the highest concentration of the mixture of cyanobacteria was offered 60 days from incubation in clay loam soil (12.00 ×104 cfu g-1 dry soil). Since there has been a significant development, the implanted cyanobacterial species were shown to cover the soil surface, mainly when a mixture of cyanobacterial species was used to inoculate soils. | ||
