TLDR
In this article, the physical properties of worm casts with the properties of the surface 0 to 5 and 5 to 10 centimeters of soil under different management systems for an Alfisol in southwestern Nigeria.Abstract:
We compared physical properties of worm casts with the properties of the surface 0 to 5 and 5 to 10 centimeters of soil under different management systems for an Alfisol in southwestern Nigeria. Soil management treatments consisted of comparison of notillage with conventional plowing and harread more

Soil carbon sequestration to mitigate climate change
TL;DR: In this article, the authors proposed a sustainable management of soil organic carbon (SOC) pool through conservation tillage with cover crops and crop residue mulch, nutrient cycling including the use of compost and manure, and other management practices.

The role of biology in the formation, stabilization and degradation of soil structure
TL;DR: In this paper, the formation of soil structure involves the physical forces of shrinking and swelling created by changes in water status of soils, freezing and thawing, tillage, or by movement of the larger biota in soils.

Earthworms and management affect organic matter incorporation and microaggregate formation in agricultural soils
TL;DR: In this article, the impact of earthworm activity on soil macro-and microaggregation and soil organic matter incorporation in different farming systems was studied. And the results showed that earthworms can directly initiate the formation of microaggregates, which in turn affects the physical protection of SOM against microbial decay.

Effects of macrofauna on soil properties in tropical ecosystems
TL;DR: In the tropics, termites and ants are more active in semi-arid and arid regions than in the United States as mentioned in this paper, and soil degradation in the Tropics is related to drastic reductions in activity and diversity of soil fauna.

Earthworm effects on selected physical and chemical properties of soil aggregates
H. Zhang,S. Schrader +1 more
TL;DR: In this article, physical and chemical properties of 1-to-2-mm aggregates obtained from casts and the burrow-wall material of the earthworm species Lumbricus terrestris, Aporrectodea longa, and Anodesa caliginosa were determined in order to show the effects of earthworms on the stabilization of soil aggregates.
