We estimate that over a 60-year period of cereal cropping under continuous cultivation, soils of NNSW and SQld have lost over 40 t C/ha (146.7 t CO2-e) and 4 t N/ha, valued at $2933 CO2-e/ha ($20/t), and $3200 for N replaced at $800/t, that is, about $100/ha/y for C and N alone... On average 2.75 t CO2-e/ha/y or 750 kg C/ha/y was released into the atmosphere over the 60-year period... Ley pastures, especially grass-legume pasture increases soil C, around 0.5 t C/ha/year or higher, during the pasture phase, but during the cropping phase soil C decreases again...
