Soil sequestration - another ideal that hasn't been grounded

 As a practical  soil scientist  who has worked across the arid and wettest areas of Australia, I specified to my old University ( Melbourne ) why soil sequestration would not work as a carbon sink in any areas of productive agricultural production in Australia ( it could be used in really moist ecosystems possibly )( over 10 years ago) 
An incentive for retaining organic matter in soils has appeal but not just for carbon compound storage . 
Without the people in the bush (that used to be there) to mediate,   the use of numbers and figures to offer incentives ( also questionable in cost benefit )  would be very wrong. 
The idea  does not recognize the complexity  of determining  sound organic matter levels in a great variety of soils and seasons and crops and the greater need and benefit  for sound ecological partnerships between farmers and scientists in the bush. . . 

The idea and the desperation for sequestration methods has been so great that other countries have fallen for this unsustainable ambition ,;
 so the pressure grows again back here , from people like former PM John Anderson and Professor Batterham   (Feature in The Australian July 2021)

Until i find my original post I will not explain why  the soil biome and the practical incentive expectation's are unsustainable as listed in those notes
