“…Earthworms form a major part of the soil fauna. Their activity is mostly considered beneficial as they promote changes in the chemical and physical characteristics of soil through biogenic structures (Fusaro et al, 2018;Xiang et al, 2018;Mergen Junior et al, 2019a, 2019bMelo et al, 2020;Teshajonova;Valihanov, 2020). Among the different types of earthworms, geophagous earthworms often have the ability to move both horizontally and vertically; this activity contributes to changes in physical attributes of soil, such as an increase in porosity, aeration, aggregation, water retention capacity, and reduction of erosive processes (Jouquet;Blanchart;Capowiez, 2014;Hallam;Hodson, 2020).…”

Earthworms are known to improve soil fertility by altering the physicochemical properties of soil. However, the changes in properties of biogenic aggregates (produced by earthworms) in regions with different vegetation covers and soils of Inceptisol toposequence in the semi-arid region have not been studied. The objective of this work was to determine the variations of the physical, chemical, and mineralogical attributes and organic fractions of biogenic aggregates of earthworms under different vegetation covers and compare them to an Inceptisol toposequence in the semi-arid region of Pernambuco State, Brazil. For this study, four Inceptisol soil profiles were selected. The sampled points were P1-upper; P2-middle third; P3-middle third; and P4-lower slope, and the soils were collected at a depth of 0-0.20 m. The biogenic aggregates were found in the P3 samples collected from three areas with different vegetation covers: an area with mesquite tree vegetation (Prosopis juliflora [Sw] D.C.); an area with neem tree vegetation (Azadirachta indica A. Juss); and an area with forage palm and mesquite tree vegetation (Opuntia sp. and Nopalea sp.). Results indicate that the biogenic aggregates were in the form of irregular blocks with a size greater than 40 mm. As compared to Inceptisol samples, these aggregates tended to select particles of smaller diameter and exhibited higher concentrations of clay minerals. The chemical and organic fraction analysis revealed that the aggregates exhibited higher Ca2+, total organic carbon (TOC), labile and humic substances, regardless of the vegetation cover. The mineralogical analysis revealed that the action of earthworms did not change the quantity or type of clay minerals.

Moringa oleifera (moringa) stands out as a promising plant in several segments, being produced worldwide. However, its co-products, particularly valves and seed husks, which represent more than 70% of its fruit, remain underutilized. Therefore, this work aimed to assess the use of parts of the moringa fruit in conjunction with sediment from an artificial pond in a zoo enclosure inhabited by Tapirus terrestris (tapir), exploring the potential treatment of these wastes, using Eisenia foetidaearthworms. Five experimental conditions were analyzed, whose waste proportions were varied. The vermicomposts were not phytotoxic and differed regarding the C/N ratio; those that received parts of the moringa fruit had a higher C/N ratio. As commonly observed in stabilization processes, the contents of P, K, Ca, and electrical conductivity increased, while carbon and pH decreased during stabilization. Plant development of Catharanthus roseus was evaluated using, in addition to the vermicomposts, two commercial composts. The vermicomposts provided better development of C. roseus than the commercial composts, with T2 (65% sediment+35% fruit valves) and T3 (50% sediment+35% valves+15% seed husks) standing out as the best treatments. Vermicomposting associated with moringa co-products and zoo waste is a viable alternative via aerobic treatment, favoring waste management and the search for sustainability.
