TLDR
In this article, the authors identified appropriate soil quality indicators from factor analysis (FA) of five treatments: no-till corn (Zee mays) without manure (NT), NO-Till corn with manure (NM), NOTILL corn with NTR, conventional tillage corn (CT), and meadow (M) in Coshocton, Ohio.Abstract:
Soil quality indicators (SQIs) can be used to evaluate sustainability of land use and soil management practices in agroecosystems. The objective of this study was to identify appropriate SQI from factor analysis (FA) of five treatments: no-till corn (Zee mays) without manure (NT), no-till corn with manure (NTM), no-till corn‐soybean (Glycine max) rotation (NTR), conventional tillage corn (CT), and meadow (M) in Coshocton, Ohio. Soil properties were grouped into five factors (eigenvalues > 1) for the 0‐10 cm depth as: (Factor 1) water transmission, (Factor 2) soil aeration, (Factor 3) soil pore connection 1, (Factor 4) soil texture and (Factor 5) moisture status. Factor 2 was the most dominant, with soil organic carbon (SOC) the most dominant measured soil attribute contributing to this factor. For the 10‐20 cm depth, factors identified were: (Factor 6) soil aggregation, (Factor 7) soil pore connection 2, (Factor 8) soil macropore, and (Factor 9) plant production. At 10‐read more

TL;DR: It is shown that NCS can provide over one-third of the cost-effective climate mitigation needed between now and 2030 to stabilize warming to below 2 °C.

TL;DR: It is found that explicit evaluation of soil quality with respect to specific soil threats, soil functions and ecosystem services has rarely been implemented, and few approaches providing clear interpretation schemes of measured indicator values limits their adoption by land managers as well as policy.

Use of indicators and pore volume-function characteristics to quantify soil physical quality
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.

Evaluating soil quality indices in an agricultural region of Jiangsu Province, China.
TL;DR: Li et al. as discussed by the authors analyzed the soil quality of Zhangjiagang County, a rapidly developing region of China, using the integrated quality index (IQI) and Nemero Quality Index (NQI) in combination with three indicator selection methods: total data set (TDS), minimum data set(MDS), and Delphi Data Set (DDS).

Suitability of enzyme activities for the monitoring of soil quality improvement in organic agricultural systems
TL;DR: In this article, the authors compared 18 pairs of organic and neighbouring conventional olive orchards in southern Spain, and found that organic management resulted in significantly higher soil enzyme activities, while conventional management did not differ in their impact on basic soil physico-chemical properties, except for loss of on ignition and available inorganic N.
