The impacts of 20-yr using amendments on the restoration of properties of an Alfisol was evaluated at the Waterman Farm, Agricultural and Natural Resources Laboratory, Columbus, Ohio. The objectives of the experiment were to assess: (1) the effects of organic and inorganic amendments on soil aggregates, and (2) carbon (C) and nitrogen (N) budgets of soil removed (20 cm deep) and undisturbed plots after 20-yr was used to conduct the experiment. Five treatmentents were used in the rendomized block design viz; (1) permanent grass field, (2) soil artificially removed-N fertilizer added, (3) soil artificially removed-compost added, (4) an undisturbed (surface soil not removed)-N fertilizer added, and (5) an undisturbed surface soil-compost added.
