  Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...

application of additives on soil surface has been considered to control runoff and soil erosion as well as the necessity of recycling. however, application of the environmentally-friendly techniques has been less taken into consideration. hence, the present study was planned to determine the effect of combination of vermicompost (24 g) with sugarcane vinasse (22 cm3) on runoff and soil loss at ...

In this research, the impact of a carbon sequestration project, in the Hossein Abad Plain in Southern Khorasan Province of Iran, on the status of water and wind erosion was evaluated. The study area has a harsh climatic condition with low annual precipitation and is prone to well-known 120-day winds in summer. Since 2005, various soil conservation treatments (plantations, over-sowing, plantatio...
