TL;DR: In this paper, an indicator of soil quality that evaluates soil ecosystem services through a set of five subindicators, and further combines them into a single general Indicator of Soil Quality (GISQ) is presented.

TL;DR: In this article, the authors evaluated soil macro invertebrate communities and soil-based ecosystem services (climate regulation, hydrologic functions, soil stability provided by macro aggregation and nutrient provision potential) in four major production systems: improved pastures, annual crops (rice, corn and soy bean), oil palm and rubber plantations, and compared them to the original savanna.

TL;DR: In this article, the authors propose a conceptual framework for sustainable use of the soil resource and present seven general research questions whose resolution will provide a firmer base for the proposed conceptual framework.

TL;DR: In this paper, the origin of aggregates separated according to visual criteria could be determined by comparing their specific organic matter signatures assessed by Near Infrared Spectrometry (NIRS) to signatures of biogenic structures produced by soil ecosystem engineers living in the same soil.

TL;DR: The results suggest that fauna density is affected by titter quality and that it is more affected by resource quantity than quality and the importance of nitrogen fixers to ecosystem function is confirmed.
