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 article, the carbon sequestration in CA is accomplished through the addition of carbon through residues, protection of soil organic carbon in soil aggregates under minimum soil disturbance and addition of soil Organic Carbon (SOC) to deeper soil layer due to the inclusion of legumes in the cropping system.
