TLDR
In this article, a comparative soil quality evaluation is performed in which the performance of the system is determined in relation to alternatives, and the results show that the effect of a reduction in tillage on the variation in total porosity with depth may be related to differences in traffic on different sites, or on soil quality at the time tillage was reduced or stopped.Abstract:
Conservation agriculture has been proposed as a widely adapted set of management principles that can assure more sustainable agricultural production. Conservation agriculture removes the emphasis from the tillage component alone and addresses a more enhanced concept of the complete agricultural system. Applying conservation agriculture essentially means altering literally generations of traditional farming practices and implement use. Within the framework of agricultural production, high soil quality equates to the ability of the soil to maintain a high productivity without significant soil or environmental degradation. A comparative soil quality evaluation is one in which the performance of the system is determined in relation to alternatives. Inconsistent effects of a reduction in tillage on the variation in total porosity with depth may be related to differences in traffic on different sites, or on soil quality at the time tillage was reduced or stopped.read more

TL;DR: In this paper, the conditions under which farmers have a private interest in preserving their soil quality were investigated and the existence of an equilibrium was shown to depend on the cooperation between soil quality and productive inputs.
Soil resource, at the core of competitiveness and sustainability issues in agriculture: An economic approach
TL;DR: In this article, a review of agronomic and economic articles shows the importance of considering soil quality in the productivity and sustainability of farms and proposes an optimal control model that illustrates the links between farming practices and soil quality when soil quality is considered as an endogenous production factor.

Stabilization mechanisms of soil organic matter: Implications for C-saturation of soils
TL;DR: The relationship between soil structure and the ability of soil to stabilize soil organic matter (SOM) is a key element in soil C dynamics that has either been overlooked or treated in a cursory fashion when developing SOM models as discussed by the authors.
