USEFUL MICROORGANISMS SUPPRESS THE SALT-INJURY IN SOIL

摘要

In Pakistan and surroundings the ground in highly contaminated with salt. Looking white like a snow sheet. In the present experiment, by administration of EM compost to the ground together with EMI active solution, the soil composition of the ground was amended with increasing organic components and microorganisms. In addition, the chemical mechanism of the decreased contamination of the solution salts in the ground was investigated. After the administration of the EM compost and EMI active solution, varieties of the microorganisms in the amended soil were compared with those in the non-amended ground. From the results, we confirmed that amendment of the soil facilitated diversity of the microorganisms in the ground. The soil facilitated diversity of the microorganisms in the ground. The soil conditions observed by the analyses of the total carbon content, ICP, XPS (ESKA)and XRD indicated that the water-soluble salt in the ground were changed to the insoluble chelate forms in the amended soil. Furthermore, amended soil formed granular clod with increased activity of ion exchanged.
