“…In addition, an increase in SOC pool is also important for improving the soil quality and increasing the agronomic productivity. The SOC pool can be enhanced through the use of appropriate crop rotations (Wright and Hons 2005), soil fertility management (Lal 2010a, Srinivasarao et al 2012, inorganic fertilizers, applying ISSN (Schuman et al 2002, Majumder et al 2008, Srinivasarao et al 2011) and appropriate tillage methods (Lal 2009, Dalal et al 2011. In rainfallscarce environments, such as those prevalent under arid and semi-arid regions of the tropics and sub-tropics, soils are also inherently low in SOC pools.…”
