Effect of grazing on carbon sequestration and tree growth that is developed in a silvopastoral system under wild cherry (Prunus avium L.)

Silvopastoral systems have been considered a good tool for carbon sequestration by taking up atmospheric carbon dioxide and storing it in the soil. The effect of animal presence on carbon sequestration in this type of agroforestry system has been studied recently. However, the soil carbon storage in...

Description
Summary:Silvopastoral systems have been considered a good tool for carbon sequestration by taking up atmospheric carbon dioxide and storing it in the soil. The effect of animal presence on carbon sequestration in this type of agroforestry system has been studied recently. However, the soil carbon storage in these systems is influenced by the stocking rate. In addition, soil fractions have been known to influence carbon storage. This study was undertaken in order to examine the effects of livestock grazing at two different stocking rates [Light Stocking Rate (LS; 4sheepha−1) and Heavy Stocking Rate (HS; 8sheepha−1)]. This was compared with the soil chemical and physical properties of No Grazing (NG) pastures, the amount of C stored in the whole soil, in three different soil fractions (250–2000, 53–250, and
