Effects of treated sewage sludge levels on temporal variations of some soil properties of a Typic Xerofluvent soil in Menemen Plain, Western Anatolia, Turkey

Abstract

The aim of this study is to determine effects of treated sewage sludge (TSS) levels as an organic matter (OM) resource on temporal variations of some soil properties of a Typic Xerofluvent soil. The experiment was conducted in Menemen Plain, in the Western Anatolia Region of Turkey (latitudes 38 degrees 34'48.22''-38 degrees 34'49.24'' N; longitudes 27 degrees 1'23.05-27 degrees 1'24.14'' E) in the years of 2003 and 2004. Moist TSS was added to the soil at the rates of 0, 30, 60 and 90 t ha(-1) on May 1, 2003. Peanut (Arachis hypogaea) was planted as first crop. On the other hand, mixture of green barley (Hordeum vulgare) and common vetch (Vicia sativa L.) was planted as second crop. During the experiment, soil samples were taken in five different periods (1st, June 18, 2003; 2nd, November 13, 2003; 3rd, April 30, 2004; 4th, October 10, 2004 and 5th, May 12, 2004). The results showed that increasing TSS application to Typic Xerofluvent soil was significantly increased total salt, OM, total porosity, micro porosity, macro porosity, field capacity, wilting point, available water content, structure stability index and aggregation percentage values of soil when compared with control. Meanwhile, particle density, dry bulk density and nonaggregated silt + clay values of soil decreased. On the other hand, soil reaction (pH), lime content and total silt + clay values of soil did not significantly change. In the course of time, depending on decomposing of TSS organic materials in soil, effect of TSS levels on soil properties decreased particularly in the last periods. For this reason, it can be recommended that 90 t ha(-1) moist TSS can be added once in 2 years for improving soil properties of Typic Xerofluvent soil, which are characterized by low OM content.

Influence of Treated Sewage Sludge Applications on Corn and Second Crop Wheat Yield and Some Properties of Sandy Clay Soil

“…Treatments of increasing TSS levels significantly increased OM content of soil samples in the average of 5 periods. Analogously to our study, Delibacak et al (2009b) found out an increase in the concentrations of OM in soil caused by increasing doses of sewage sludge introduced to soil.…”

Temporal variability in organic amendment impacts on hydro‐physical properties of sandy agricultural soils

“…However, seasonal improvements and differences between seasons generally correlate better with OA quantity indicators (i.e., application rates) than with OA quality indicators (i.e., compositional properties). Other OA studies without combined mineral fertilizer applications have similarly observed the importance of OA application quantity over differences in OA type (Barzegar et al., 2002; Castellini et al., 2022; Delibacak et al., 2009; Tejada & Gonzalez, 2008).…”

“…Yet little is known regarding the seasonal variability of OA impacts as most studies evaluate changes in soil properties at fixed yearly intervals (Cercioglu, 2017; Ferreras et al., 2006; Tejada & Gonzalez, 2008) or once at the end of an experiment (Li et al., 2018; Singh Brar et al., 2015; Yüksel & Kavdır, 2020; Zhao et al., 2009). Studies that do explore short‐term OA impacts observe strong seasonal fluctuations in the response of soil hydro‐physical properties to applications of OAs such as compost (Castellini et al., 2022; Felton, 1995), sewerage sludge (Delibacak et al., 2009), and biochar (Ouyang et al., 2013). These seasonal variations can furthermore differ strongly per soil hydro‐physical property (Zare et al., 2010).…”

“…The nutrient value of organic wastes is considered to be moderate (Petersen, 2001), although the variation in waste quality is large dependent on waste type and processing method (Smith et al 1998). Delibacak et al (2009), found that addition of increasing treated sewage sludge application to Typic Xerofluvent soil was significantly increased total salt, OM, total porosity, micro porosity, macro porosity, field capacity, wilting point, available water content, structure stability index and aggregation percentage values of soil when compared with control.…”
