Our new rolling survey which continues sampling in the same locations as before, but over 5 yearly cycles, is focussed on the following questions:
• Is soil carbon still being lost in arable soils at 0.4% a year (11% since 1978) as reported the 2007 survey?
• Are increases in soil carbon for improved grassland still being seen (2% increase since 1978) ?
• Are worrying trends for declining soil carbon in some upland soils now confirmed?
• Can we better track change in soil carbon using subcomponents of the soil carbon pool?
• Does a metagenomic approach provide better information on soil biodiversity change?
• Has recovery from acidification due to acid rain halted?
• Is the physical structure of soil declining as indicated by bulk density and aggregate stability?
• Are phosphorus levels continuing to decline?
• Can we detect a nitrogen deposition signal?
• Can we better represent ongoing trends in soil carbon using a new soil carbon model?
Our first report on findings from this new survey will be in 2022 for soil carbon and 2025 for the full survey.
