Gyttja as a Soil Conditioner: Changes in Some Properties of Agricultural Soils Formed on Different Parent Materials

The occurrence of heavy metals in agricultural areas, whether due to natural processes or human activities, poses significant risks to both the ecosystem and public health through their incorporation into the food chain via plants. This study aimed to evaluate the concentrations of metals and the pollution risk levels in ultramafic soils within Kahramanmaraş and its surrounding districts (Türkoğlu, Ekinözü, Afşin) in the Eastern Mediterranean region. A total of 56 samples, consisting of 28 surface soil samples (0-30 cm) and 28 parent material samples (90 cm+), were collected from these areas. Various pollution indices, including the enrichment factor (EF), geoaccumulation index (Igeo), pollution load index (PLI), and contamination factor (CF), were utilized to assess both natural and human-induced impacts on the ultramafic soils. The findings indicated that the concentrations of Ni, Cr, and Co in the topsoil layer (0-30 cm) exceeded the maximum limits established by the World Health Organization. Despite this, the pollution indices (EF, Igeo, PLI, and CF) for these elements were relatively low, suggesting a similar composition between the parent material and the soil. This points to the natural occurrence of these heavy metals in the soil. On the other hand, the pollution indices for Pb and Cu indicated human-related influences on these elements. Additionally, there was no significant enrichment of Mn or Cd from either natural or human sources. Environmental hazards such as erosion and dusting are common in areas affected by pollution, whether natural or anthropogenic. To address these issues, specific management practices are necessary, such as reducing soil disturbance in polluted agricultural zones or maintaining permanent vegetation cover to stabilize the soil.

In the study, the changes in the structural stability and erodibility properties of the organic regulators (TG, TAGG and SG) applications to serpentine soils were investigated. In line with the study's objective, organic amendments based on oven dry weight were applied to the soils in different dose combinations. The study, designed according to a completely randomized design (CRD) was conducted in plastic pots maintained under greenhouse conditions. Six months after the experiment was established, the pots deteriorate pots were and the necessary measurements were made. WAS, DO, EO, SSI, OM values were measured to evaluate the change in the erosive and structural stability of the soils. As a result of the study, the OM values of the soils increased with the organic regulator applications (TAGG, TG, SG). The highest increase was observed in pots where TG and TAGG were applied. The erodibility parameters of the soils, DO and EO, showed a decrease with increasing dosage applications. WAS and SSI parameters, which are soil erosive variables, increased with increasing application dose. These increases (WAS, OM, SSI) and decreases (DO and EO) depending on the applications were statistically significant (p
