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

Restoration of tropical peat soils: The application of soil microbiology for monitoring the success of the restoration process
TL;DR: In this article, soil sampling was carried from a tropical peat swamp forest and a burned oil palm plantation as comparisons, which revealed substantial differences after 3.5 years of restoration between the restored soil and both burned palm plantations and the natural forest soils.

Assessing the effectiveness of Sustainable Land Management for large-scale climate change adaptation
Jpc Eekhout,J. de Vente +1 more
TL;DR: It is shown that the on-site and off-site impacts of climate change are almost entirely reversed by the large-scale implementation of SLM under moderate climate change conditions, characterized by limited reductions in annual precipitation but significant increased precipitation intensity.

Nitrogen fertilizer placement and timing affects bread wheat ( Triticum aestivum) quality and yield in an irrigated bed planting system
Kathrin Grahmann,Kathrin Grahmann,Bram Govaerts,Simon Fonteyne,Carlos Guzmán,Ana Paullette Galaviz Soto,Andreas Buerkert,Nele Verhulst +7 more
TL;DR: In this paper, the effect of placement and timing of nitrogen fertilizer on performance and quality of the bread wheat cultivar Navojoa, was tested in two tillage systems under furrow irrigation: conventionally tilled beds (CTB) and permanent beds (PB).

TL;DR: In this article, the mid-term effects of permanent bed planting on soil compaction, root growth, crop yield and carbon sequestration compared with conventionally tilled bed planting (CB) and with a variant of PB that had partial subsoiling (DPB) in a Typic Xerofluvents soil in southern Spain.

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.
