Cover crops provide an effective practice to enhance SOC [10-13] in addition to their role in improving soil and water conservation [14]. Cover crops can also enhance soil fertility and productivity for a sustainable agricultural production [15,16]. A linear relationship has been reported between the amount of Carbon sequestered in the soil and Carbon input as plant biomass or residues by a number of researchers [17-19]. Removal of cover crop tops from the soil greatly decreased soil Carbon [20]. The growth rates and amounts of cover crop biomass as well sequestered CO2 Carbon differed among different cover crop species and environmental factors [3].
