Soil compaction by farm machinery may persist for decades, hampering soil productivity and functioning. Assessing costs guiding recovery strategies are hindered paucity of data on structure rates. A long-term Structure Observatory was established a loamy in Switzerland to monitor after prescribed compaction, better assess the roles natural processes (vegetation, macrofauna, shrink-swell cycles)...

Changes in surface soil C and N can resuh from forest management practices and may provide an index of impacts on long-term site productivity. Soil C and N were measured over time for five watersheds in the southern Appalachians: two aggrading hardwood forests, one southand one north-facing, undisturbed since the 1920s; a white pine (Pinus strobus L.) plantation planted in 1956; and two regener...
