“…In the case of constructed Technosols, earthworms and plants shape the hydrostructural properties that have been reported to be more important than the effect of parent materials (Deeb et al, 2016a). Fonte et al (2012) showed that the interaction between earthworms and plants increases aggregate stability, as well as OC concentration in the earthworm casts. It has also been shown that interaction between organic matter input and plant roots improves aggregate stability in degraded land (Caravaca et al, 2002).…”

“…For instance, LorangerMerciris et al (2012) showed that P. corethrurus enhanced dessert banana growth through increased P availability in its casts. In another study, the presence of P. corethrurus increased aboveground biomass of Brachiaria decumbens by 30%, via increased availability of soil nutrients (Fonte et al, 2012).…”

“…The activity of such endogeic geophagous earthworms is often considered to increase C mineralization in the short term and favour C storage through the stabilization of SOM in stable micro-aggregates in the long term Lavelle and Martin, 1992;Lavelle and Spain, 2001). The influence of earthworms on SOM and nutrient dynamics may depend on a number of factors including the time frame in question but also inherent soil properties, the form of management in place and the interaction with plants (Fonte et al, 2012). Using microcosm experiments, showed that, in the first 15 cm layer of the soil, P. corethrurus decreased the total soil C by 3% under the Quesungual slash-and-mulch agroforestry system of western Honduras (QSMAS).…”

A B S T R A C TExotic peregrine earthworms are often considered to cause environmental harm and to have a negative impact on native species, but, as ecosystem engineers, they enhance soil physical properties. Pontoscolex corethrurus is by far the most studied morphospecies and is also the most widespread in tropical areas. The term of morphospecies is used in this review because P. corethrurus may in fact constitute a complex of cryptic species. This earthworm is found in a wide range of habitats, from apparently pristine to any kind of human-disturbed environment. This review synthesizes 265 studies describing the distribution, morphology, biological and ecological traits of this morphospecies, as well as its impacts on soil conditions and communities. We then discuss the characteristics necessary for this specific morphospecies to become a successful colonizer throughout the world and the positive and negative effects it can have on the ecosystems that it has invaded. We emphasize the lack of knowledge of P. corethrurus reproductive mode and ploidy level, of its population genetics, and of the potential existence of cryptic species. To finish, we highlight the fact that data on P. corethrurus interactions with non-earthworm soil macrofauna are scarce.

“…5) overlying a compacted and thicker soil layer. The vigorous root systems of tropical grasses (e.g., the Brachiaria and Cynodon genera) can increase aggregate stability and improve soil structural quality (Vezzani and Mielniczuk, 2011;Fonte et al, 2012). Large root systems promote high C inputs and act on the formation and stabilization of soil structure.…”

Cherubin, Maurício R.; Franco, André L.C.; Guimarães, Rachel M.L.; Tormena, Cássio A.; Cerri, Carlos E. P.; Karlen, Douglas; and Cerri, Carlos C., "Assessing soil structural quality under Brazilian sugarcane expansion areas using Visual Evaluation of Soil Structure (VESS)" (2017 Increasing global demand for biofuel has accelerated land-use change (LUC) in Brazil, primarily through the planting of sugarcane (Saccharum officinarum) to replace degraded pastures. The intensive mechanization associated with this LUC has increased concerns regarding structural quality of Brazilian tropical soils. Through decades of research focusing on identifying sensitive indicators of soil degradation due to land use and management, the Visual Evaluation of Soil Structure (VESS) method has emerged as a simple, fast, reliable and accurate semi-quantitative approach for assessing soil structure changes. VESS integrates soil properties related to size, strength and porosity of aggregates, and root characteristics into a single score (Sq -structural quality) that ranges from 1 (good structural quality) to 5 (poor structural quality). Although the VESS method was developed for temperate soils, it has been used successfully as an indicator of soil and crop management practice effects on structural quality of tropical and subtropical soils. Our objectives were to evaluate soil structural quality changes associated with a LUC sequence (i.e., native vegetation to pasture to sugarcane) at three sites under Oxisols, Alfisols and Ultisols across centralsouthern Brazil using the VESS; and to correlate VESS scores with quantitative measurements of soil physical properties. Average VESS scores were 2.0, 2.7, and 3.1 for native vegetation, pasture, and sugarcane, respectively. Overall the VESS method was able to detect soil structural quality changes under LUC for sugarcane cultivation, indicating a decrease in soil quality from native vegetation through pasture to sugarcane. The VESS scores were significantly correlated with quantitative soil physical property measurements, suggesting VESS is a reliable indicator of soil structural quality in tropical soils. A VESS score Sq = 3.0 seems to be suitable as a guide for management decisions. We conclude that VESS scores provide an efficient method to identify impacts of sugarcane expansion on soil structural quality, and recommend that VESS assessment be incorporated into monitoring protocols for evaluating not only sugarcane expansion areas, but also overall soil quality/health in Brazil.
