Impact of Organic Wastes on Physical and Chemical Properties of Sandy and Loamy Soils in Egypt

The aim of this study was to evaluate the effect of two organic wastes used as soil amendments i.e. filter mud cake (FMC) and vinasse (V) on some physical and chemical properties of sandy and loamy sandy soils. Applications of organic were incubated with the soils for a three periods of 15, 30 and 60 days at four application rates (0, 0.5, 1 and 2%). This study was carried out in a two way randomized completely block design with three replications. After incubation periods, bulk density, porosity, water retention, soil pH, electrical conductivity (EC) and organic matter were determined.

Results showed that the values of soil bulk density and soil pH were decreased with increasing the application rates of filter cake or vinasse compared with the control in two soils. In addition, application of different filter mud cake and vinasse rates to the study soils increased soil porosity, field capacity (FC), wilting point (WP), available water (AW), electrical conductivity (EC) and organic matter contents (OM) as compared to control at different period incubation time. The data of this study concluded that, organic wastes or byproducts of sugar industries could be applied to improve some soil properties.
