“…In the study by Soichiro and Koichi [26], climate change may alter the balance between litter and aboveground biomass by changing aboveground net primary production and decomposition rates along elevation gradients in central Japan. With the deepening of research on litter ecology, an increasing number of experts and scholars in the fields of ecology, forestry, and environmental science have focused on litter function [8,[27][28][29].…”

Litter is an important component of forest ecosystems and plays an important eco-hydrological function. Many studies have been carried out on litter at present, but less research has been carried out on the eco-hydrological service functions of litter in different plant communities in Karst, especially in the area of Karst peak-cluster depressions in southwest China. To reveal the characteristics of the hydrological function of the litter layer of the plant community in the area of Karst peak-cluster depressions around FAST (Five-hundred-meter Aperture Spherical Radio Telescope), three typical plant community litter layers of the broad-leaved forest, coniferous forest, and shrub were selected as research objects, and the hydrological function of the litter layer of different plant community types was studied using the immersion method. The results indicated: 1) The litter layer of the broad-leaved forest plant community has the strongest function of intercepting and regulating precipitation (Mlmax = 24.17±0.33 t/ha, Msv = 19.93±0.21 t/ha), and its hydrological service function is the best. 2) The higher the decomposition degree of litter, the stronger the interception function. 3) The fitted equations for both the litter water-absorption capacity (Qct) and time (t) for plant communities were Qct = b + alnt, and the fitted equations for both the litter water-release capacity (Qst) and time (t) were Qst = a t b. 4) The fitted equations for both the water absorption and release rates (vc and vs) and time (t) of the litter were v = a t -b. The water absorption rates of litter were the fastest within 5 min (15529.01~22634.43 g/kg·h), with the greatest interception and storage function for short-term rainfall.

“…(3) N-rich maize litter caused a smaller true priming effect than N-poor Rhodes grass litter. Schroeder et al (2020) also did not find any effect of incubation time, although the metabolization of added complex substrates is usually incomplete to different extents at specific sampling dates (Faust et al 2019). However, incubation times of 7 and 42 days used by Schroeder et al (2020) may still not be the optimum for estimating CUE values of plant residues, which requires additional experimental efforts.…”

“…Less information is available on the CUE of complex plant residues (Muhammad et al 2006;Rottmann et al 2010;Sauvadet et al 2018), which can be determined by the recovery of added substrate as particulate organic matter (Magid and Kjaergaard 2001). This approach is often combined with the difference in δ 13 C of C4 plants and SOC mainly originating from C3 plants (Ryan and Aravena 1994;Balesdent and Mariotti 1996;Faust et al 2019).…”

An incubation study was carried out to investigate the effects of litter quality, i.e. 15 N-labelled maize (C/N of 25.5) and Rhodes grass (C/N of 57.8) leaf litter on microbial carbon use efficiency (CUE) and priming effects in a moderate alkaline soil at two different temperatures (15 and 25 °C). CUE values were calculated from the isotopic composition of the particulate organic matter (POM) recovered as an index for the amount of non-decomposed litter. This approach allows the inclusion of microbial necromass growth components in the calculation of CUE values. Additionally, the soil was incubated for 10, 20, and 30 days to determine the optimum incubation period. Soil microbial CUE values of maize and Rhodes grass leaf litter, including microbial necromass C in the calculation of CUE, varied around 0.61, regardless of litter type, temperature, and incubation period. However, the optimum incubation time is between 20 and 30 days, depending on temperature. The strong priming effect on autochthonous soil organic carbon (SOC) mineralization was apparently not caused by N mining, as it was similar for both litter qualities. It most likely resulted from SOC being used by microbial co-metabolism. The litter-induced true priming effect was accompanied by a significant increase in autochthonous POM. The current approach, including microbial necromass as growth component, has been shown to be a strong tool for investigating CUE values and priming effects after application of litter and harvest residues to soil, probably under all environmental conditions.

“…Contact of crop residues to the surrounding soil enhances their accessibility to microorganisms and soil fauna (Faust et al, 2019;Potthoff et al, 2008). However, soft-bodied soil detritivore animals incapable of burrowing such as Collembola may be unable to access the incorporated litter material representing an important food resource (Dittmer & Schrader, 2000;Stinner et al 1988).…”

Background The role of soil mesofauna in decomposition processes still is debated and this applies in particular to arable systems. Aim This study investigates the role of Collembola in decomposition processes of crop residues in two different tillage systems. Methods We conducted a litterbag experiment in a long‐term field site in Germany managed by conventional tillage (CT; mouldboard ploughing) and minimum tillage (MT). Litterbags filled with maize leaf litter of two mesh sizes (2 mm and 48 μm) were used. Litterbags were buried at 23 cm (CT) and 5–8 cm (MT), and retrieved after 2, 5 and 7 months. Litter mass, concentrations of carbon and nitrogen, litter C/N ratio as well as the abundance and community structure of Collembola and the incorporation of maize‐derived carbon into Collembola were investigated. Results Mesofauna enhanced the loss of litter carbon, while litter mass loss was reduced. Litter C/N ratio in MT was generally lower than that in CT and decreased faster in litterbags with coarse mesh size. Abundance of Collembola in litterbags in CT exceeded that in MT, but species composition remained unaffected by tillage. Overall, Collembola effectively colonised the litter irrespective of tillage system, but benefited in particular from translocation deeper into the soil by conventional tillage. Conclusions Mesofauna accelerates litter carbon loss and increases litter nitrogen accumulation irrespective of tillage system. This may reduce nitrogen losses due to leaching in winter and facilitate nitrogen capture from decomposing litter material by crops in the following season, thereby contributing to the sustainable management of arable systems.
