The study effect of Turkey nest on soil characteristic in the arid regions (Case study southwest of Sistan)

The purpose of this research is to study the effect of the turkey nest on soil characteristics in arid regions. In order to carry out this work, the structural status of the turkey nests was studied. Four soil samples were taken from the control and four samples were selected from the inside of the turkey nests as well. Texture features, calcium, sodium, magnesium, soluble sodium percent, sodium absorption ratio, acidity, electrical conductivity were measured and the results were analyzed descriptively in order to investigate the performance of the structures regarding the soil improvement and soil regeneration and to determine its physical and chemical characteristics. The results of the analysis of the physical properties of soil samples show that the sand percentage of the turkey nest treatment decreased by 184% compared to the control, and clay and silt increased by 10% and 62.5%, respectively. Investigating the chemical properties of the soil also suggests that the acidity of the turkey nest soil samples has increased slightly and the electrical conductivity (EC) decreased by 239.3%. Also, the amount of calcium cations, magnesium cations and sodium decreased by 210, 102 and 131%, respectively, in the soil of the turkey nest samples compared to the control.
