TL;DR: The Dexter "S -value" (S gi ) is a promising new indicator of soil physical quality (SPQ), but it is not well tested against established indicators, such as relative field capacity (RFC), plant-available water capacity (PAWC), air capacity (AC), macroporosity (P MAC), bulk density (BD), organic carbon content (OC), and structural stability index (SI) as discussed by the authors.

TL;DR: In this paper, the effects of different tillage systems on organic C and N storage were determined for a range of soils of eastern Canada mainly under continuous corn and small grain cereal production.

TL;DR: In this paper, the optimal values of soil physical quality (SPQ) parameters for enhancing field-crop productivity while maintaining or improving environmental health are still largely unknown, and progress toward identifying optimal values for some SPQ parameters might be made by comparing parameters obtained from longterm conventional tillage cropping (CT), long-term no-tillage Cropping (NT), and virgin woodlot (WL) treatments located on Fox sand (Psammentic Hapludalf), Guelph loam (Mollie Haplodalf), and Brookston clay

TL;DR: This paper found that residue quality plays a key role in increasing the retention of soil organic matter in agroecosystems and that soils under legume-based rotation tend to be more "preservative" of residue C inputs, particularly from root inputs, than soils under monoculture.

TL;DR: In this paper, the effects of fertilization on soil organic matter turnover and storage of residue C under continuous corn were evaluated using soils from a long-term field experiment in Ontario.
