Role of Dung Beetles in modifying soil physical and chemical properties in the semi steppe rangelands Shahrekord

The present study aimed to investigate the effect of functional groups dung beetles in modifying some features of soil physical and chemical Decomposition of cattle dung on pasture University Shahrekord in a randomized complete block design. In order to Grid with holes the size of large and small cattle manure in seven different modes, plus a control state with three replications each was selected as treatments. The results showed that soil physical properties Clay percentage control less than all states and greatest amount related to states 1 and 3 in the silt state 7 was lower than all states and greatest amount related to case 5 and in conjunction with sand state 3was lower than all states and most of related to controls Also the chemical properties of soil obtained different results in a manner that controls in relation to phosphorus and potassiumof all states were lower and greatest amount of the elements related to states 2 and 3 In the state of manganese, and iron results showed that most of the elements related to states 1 and 3 and the amount of each of the elements of the controls The results of elemental calcium showed the highest and lowest levels of the element related to states 4 and 3 in conjunction with magnesium highest and lowest rates of 6 states 2 and the sodium element greatest amount related to mode 2and the lowest element of the controls.
