Globally, poorly managed pasture can contribute to increasing greenhouse gas (GHG) emissions. In Brazil, sustainable management systems are being proposed to reduce carbon dioxide (CO2) emissions and increase the soil C stock under degraded pasture. However, despite the potential benefits in the adoption of sustainable management systems, few studies have been carried out seeking to analyze their long-term

Anecic earthworms generate more topsoil than they contribute to erosion – Evidence at catchment scale in northern Vietnam Catena (IF 4.333) Pub Date : 2021-02-16 N. Bottinelli; J.L. Maeght; R.D. Pham; C. Valentin; C. Rumpel; Q.V. Pham; T.T. Nguyen; D.H. Lam; A.D. Nguyen; T.M. Tran; R. Zaiss; P. Jouquet
Soil is considered as a non-renewable resource, which may be lost in sloping land more rapidly than it is formed thus leading to loss of fertility and ecosystem deterioration. We hypothesized that earthworms could counteract this process due to their cast forming activity. To test this hypothesis, we quantified the production of casts in small plots of 0.25 m2 established in three vegetation units
