[QUOTE="Agrispeed, post: 6234722, member: 10619"] We've been increasing OM for about 10 years and have grassland fields at 18% now. I have been told the figure will plateau at some point (although no one can tell me when) The soil will still build carbon, but not as a %, but you will continue to build soil if that makes sense. We have entered into a load of extra testing as the results as measured (30m grids across a field and at 3 depths, sent to 2 labs and through 3 organisations) got results that are apparently impossible to achieve according to some, and has caused a lot of arguing between 2 factions of soil scientists. Soil biology is quite good at metabolising chemicals, so I think some of the chemical guys recommend keeping OM low to improve the effectiveness of chemical control. o_O:facepalm: [/QUOTE]
