Influence of Organic Amendments Based on Garden Waste for Microbial Community Growth in Coastal Saline Soil

Garden waste compost (GWC) has been applied as an amendment to improve the desalination efficiency, nutrient availability and diversity of microbial community in coastal saline soil. Understanding response garden application is great significance ecological restoration. Four treatments were established: CK, nonamended control; T1, 68 kg·m−3 compost; T2, 15 bentonite; T3, a mixture bentonite. In addition, soil physicochemical properties, enzymes, biomass carbon measured. The results show that T3 had more significant effect on increasing well nitrogen, urease, sucrase dehydrogenase activities. Based relative abundance, linear discriminant size (LEfSe) analyses, amendments can be seen have increased abundance alpha bacterial structure also altered structure. RDA Pearson correlation analysis at phylum level indicated available total porosity, hydraulic conductivity, bulk density EC primary determinants communities associated with this amendment. conclusion, enables microorganisms participate material cycle, indicating composting beneficial restoration soils.
