Cambodia has faced drastic agrarian changes over the last twenty years with a rapid and massive transformation of the uplands from forest into arable land. Soil quality depletion is one of the main drivers of the resulting decline in crop productivity and increasing production costs in the uplands of Battambang province. The objective of the study was to assess the early effects of conventional plough‐based (20 cm) management (CT) and two conservation agriculture‐based (CA) cropping systems (the use of a single—CAS vs. multiple cover crop species—CAM) on a maize monocropping system using three soil organic carbon (SOC) fractions on Mollisols in Battambang province. SOC content, permanganate oxidizable carbon (POXC) and soil CO2 basal respiration through SituResp® were recorded at a depth of 0–10 cm. Twelve sampling periods were used over the growth period of the cover crops and during the maize cycle. POXC and SituResp® were highly sensitive to management practices with, across the 12 sampling periods, higher values (p < .05) under CA than CT, with an average increase of 6% and from 20% to 23%, respectively. No difference was observed in SOC content between the practices in our sampling periods. Seasonal variations were observed in both POXC and SituResp®. POXC underwent larger fluctuations following critical weather events than SituResp®. This study showed that POXC and SituResp® were rapidly sensitive to changes in agricultural management practices. POXC and SituResp® are largely influenced by seasonality and could help clarify the impact of weather patterns on soil C dynamics.

“…In situ basal soil respiration was measured using the SituResp® method (Thoumazeau et al 2017). The SituResp® technique is based on the color change of a pH-sensitive gel in response to the change in CO2 concentration in the headspace of a soil sample during the 24-hour incubation period.…”

Aims Tree logging in tropical tree plantations results in significant soil disturbances that negatively impact soil biodiversity and soil functioning. Here, we aimed to assess the effects of adding organic matter (OM) to soil after rubber tree logging on soil functioning over time. Methods The experiment was conducted in two contrasting soil types in Ivory Coast. Four practices were replicated, including a control with no residues, the presence of legumes only, legumes and all tree parts excluding the trunk, and legumes and all the parts of the tree including the trunk. We monitored the response of soil nematode communities every six months for 24 months in each practice. Samples were collected from the topsoil layer (0–10 cm) in the interrow, and we also monitored soil carbon transformation by measuring in situ basal soil respiration, labile soil carbon and organic matter decay using the bait lamina method. Results The results showed a sharp decrease in nematode abundance after tree logging, but OM restoration increased nematode abundance, the relative abundance of bacterivores, and resource availability to the soil food web. The resilience of the nematode communities depended on soil conditions and the amount and quality of logging residues. Total nematode abundance was positively and significantly related to soil functioning, measured through basal soil respiration, labile soil carbon, and organic matter decay rate. Conclusion The results suggest that restoring logging residues can be an effective way to restore soil biodiversity and mitigate the negative impact of clear-cutting in tropical rubber plantations.
