“…Soil insects interact with microbial communities through their feeding activities, altering microbial communities and nutrient cycling processes. The activity of soil insects can influence the decomposition rates of organic matter and the release of nutrients through fragmentation and consumption, consequently affecting microbial communities and their functions [63]. Moreover, changes in microbialdriven processes, such as decomposition rates or nutrient turnover, can indirectly influence soil insect populations by altering the availability of food resources or habitat conditions.…”

Biochar, a carbonaceous material produced through pyrolysis of organic matter, has garnered attention for its potential to enhance soil fertility, structure, and overall health. However, its effects on soil-dwelling insects remain a subject of considerable interest and debate. This chapter critically examines the current state of knowledge regarding the interactions between biochar applications and soil-dwelling insects, encompassing diverse aspects such as alterations in insect community composition, population dynamics, behavioral changes, and potential mitigation of infestations. Through an exploration of empirical studies and theoretical frameworks, it aims to elucidate the intricate relationships between biochar amendments and soil insect ecology.

“…However, most of these studies focused on root exudates obtained from plants grown hydroponically or on gelose with a nutritive solution [14][15][16][17][18], meaning roots lacked living substrate as is the soil. On the other hand, several studies performed in microcosms tested how the presence of soil fauna may contribute to mineralization but mainly focused on analyzing C, N, or P content of the leachates [19][20][21][22]. For example, those studies showed that presence of soil detritivores increases the amount of nitrate in the soil and the metabolic activities of soil microbes.…”

Discrimination of compounds produced from plant roots is a challenging purpose, especially in presence of the soil matrix and the associated fauna. In this study, we aimed to test a collection method of chemical signals released by living plants and soil fauna in interaction in a soil matrix. Microcosms, with stopcock, were filled with soil, and four treatments were designed based on the presence/absence of an annual herbaceous plant, Poa annua and of a soil Collembola species, Folsomia candida. Soil leachates were collected with a percolated solution and analyzed by a fast analytical method combining analytical separation of compounds through ultra high performance liquid chromatography with high resolution mass spectrometry (UHPLC-HRMS). The experimental design appears to be suitable for leachates sampling. Detected chemicals clearly discriminated the treatments, demonstrating how biotic interactions belowground between a plant and a Collembola species may change soil chemical signals.

“…However, soil bacterial and fungal communities are highly affected by their consumers: especially the mesofauna and microfauna (Ingham et al, 1985; Seastedt, 1984). Mesofauna, mainly microarthropods have a significant indirect role in nitrogen cycling, but their effect on nitrogen‐related soil processes is still not well understood and has been inadequately studied (Filser, 2002; Lakshmi et al, 2020; Soong & Nielsen, 2016).…”

1. Soil microarthropods have a pivotal role in soil nitrogen cycling in that they affect microbial decomposers. A high abundance of microarthropods may increase the mobility of inorganic nitrogen ions in the soil, mainly in nitrogen-limited habitats. However, it is difficult to study ecological processes with small-sized, soil-4.06 ± 0.93 3.52 ± 0.34 2.70 ± 0.76 4.30 ± 0.59Abbreviation: SIR, substrate-induced respiration.
