  1. OM% = %TN × 20`; OC = OM × 0.57 and/or %OC ×1.724 = %OM. SOC stock (C (t ha−1)) is calculated from SOC concentration (C (%)) by: C(tha−1) = C(%) × ρ × D where D is soil depth (cm) and ρ is soil bulk density (g cm3); similarly, using these parameters, it was calculated as mentioned (http://www.dpi.nsw.gov.au/agriculture)
