The Effects of Organic Wastes Applied to Alkaline Soils on Some Physical and Chemical Properties of the Soil

In this study, by applying sewage sludge (SS), farmyard manure (FYM), and municipal solid waste compost (MSWC) to alkaline soils is aimed at improving the physical and chemical properties of the soils. The research was carried out for 2 years in 48 plots, 3 organic wastes, 5 doses, 3 control and 3 replications, according to a completely random trial design in field conditions. Wastes were applied in the first year of the study, and silage corn plants were grown for two years. Some physical and chemical properties of the soils were determined in the soil samples taken at the end of the vegetation period, and according to these results, the soil bulk density (BD), pH, and exchangeable sodium percent (ESP) values decreased, soil organic matter content (SOM), aggregate stability (AS), hydraulic conductivity (HC), and air permeability (AP) increased depending on the waste types and doses. According to the initial soil analysis results of the experimental area, while the ESP was determined as 18.44%, the lowest ESP was determined as 6.59% in a 125 t/ha SS application in the second year of the experiment, and the alkalinity problems of the soils were resolved according to the soil salinity classification. It was concluded that the application of organic wastes with high organic matter content to alkaline soils can be used to reclamation alkalinity by improving the physical and chemical properties of soils.
