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

Soil weed seed bank and factors influencing the number ofweeds at the end of conversion period to organic production
TL;DR: By the end of 2009 the content of organic carbon in the soil had increased significantly in both organic systems which results in higher activity of organisms that decrease the viability of weed seeds.

Weed management in conservation agriculture, its issues and adoption : a review
TL;DR: In this paper, the authors proposed an integrated weed management (IWM) approach to manage weeds effectively in an eco-friendly and cost-effective manner under conservation agriculture (CA) which is becoming popular as it brings sustainability of the production system without compromising crop and soil productivity.

Narrow rows and high maize plant population improve water use and grain yield under conservation agriculture
TL;DR: Haarhoff et al. as mentioned in this paper showed that narrow rows and a high maize plant population improve water use and grain yield under conservation agriculture, and proposed a maize-based maize-to-water transfer strategy.

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.
