      abstract     = {oils in arid and semi-arid lands are vulnerable to climate
                      change, erosion, and mismanagement practices that contribute
                      to organic matter depletion and nutrients imbalances. Oasis
                      agrosystems are considered one of the major farming systems
                      in some parts of these lands in the Middle East and North
                      Africa region. However, oases soils are inherently low in
                      organic carbon due to their sandy texture which retains
                      little water and binds low organic matter contents, and the
                      accelerated decomposition rates of organic matter under high
                      temperature, which makes its accumulation difficult.
                      Traditional farming practices in oasis agrosystems have
                      always integrated organic matter derived from livestock to
                      enhance organic carbon (OC) and total nitrogen (TN) stocks
                      in the soil. This study is aimed to examine the potential
                      effects of a new mixture of organic amendments and bentonite
                      clay on organic carbon and total nitrogen stock accumulation
                      in the soil. Five amendments were applied including sand and
                      compost (SC), sand and manure (SM), sand, bentonite, and
                      compost (SBC), sand, bentonite, and manure (SBM), and sand
                      mixed with bentonite (SB). These treatments were compared to
                      untreated soil (U). The results showed that OC and TN stocks
                      increased significantly (p<0.05) in all three depths of the
                      five treatments compared to the untreated soil. Higher
                      organic carbon stocks (2862±3.4 g m−2) were detected in
                      SBM treatment. The combined organic and mineral amendment
                      retarded OC and TN decomposition. After two years of the
                      amendments’ application, $30\%$ of OC remained in the soil
                      for SBC treatment. In conclusion, the mixed mineral and
                      organic amendment is a better choice to preserve OC and,
                      thus, maintain oasis soil fertility.},
