    The circular bioeconomy, centred on the principles of “Reduce, Reuse, and Recycle”, is central to achieving the goals of the European Green Deal and the “Farm to Fork” strategy. The key approach, within this framework, is the valorisation of food processing side-streams through various processing technologies to produce fertilisers that, when applied to the soil, act as potential “soil improvers”. When applied to soil, these materials affect not only the physical, chemical, and biological properties of soil but also impact greenhouse gas emissions, nutrient leaching, and the levels of contaminants or pathogens. A systematic review of field studies conducted in European soils between 2014 and 2024 was performed with stringent inclusion and exclusion criteria, which allowed the identification of suitable articles in three independent steps. The main soil improvers derived from various agri-food side-streams were biochar, compost, and digestate. Their effects, along with the potential risks associated with their use in agricultural fields, were carefully evaluated and discussed. This review forms part of the DeliSoil project “Delivering safe, sustainable, tailored & societally accepted soil improvers from circular food production for boosting soil health” funded under the European Union “A Soil Deal for Europe”. This systematic review showed that soil improvers enhance soil health by improving microbial diversity, organic matter, and water retention, and by boosting plant growth. However, potential risks require careful management, and long-term studies are needed to fully assess their environmental and agronomic impacts.

    Plant- and microbial-derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth-dependent mechanisms governing their accumulation remain poorly characterized, particularly for water-limited grassland systems. Based on a 13-year field experiment in a semiarid grassland, we quantified the effects of long-term N addition on the accumulation of plant- (lignin phenols) and microbial-derived (amino sugars) residues. We found that N addition significantly increased lignin phenol content and its contribution to SOC in the topsoil, whereas lignin phenols exhibited a hump-shaped response peaking under moderate N levels in the subsoil. Amino sugar concentrations and their relative contribution to SOC increased in both soil layers under N addition but declined at the highest N input. The dominant factors regulating residue accumulation varied with soil depth: in the topsoil, microbial K−/r-traits and community composition primarily explained lignin phenol and amino sugar dynamics, while in the subsoil, mineral-associated protection and microbial composition were the key drivers. These findings underscore the depth-dependent nature of SOC formation pathways and highlight the importance of incorporating both plant- and microbial-derived residues into Earth System Models to improve projections of carbon-climate feedback under changing nitrogen regimes.

    Virtual nature exposure can support wellbeing and health, but outcomes may vary by delivery technology. This study investigates how the delivery technology affects psychological immersion, presence, and VR-sickness symptoms in virtual nature. Three different technologies for delivering virtual nature were compared: TV, VR-headset, and virtual nature room. In a three-condition randomized trial with a crossover design, 62 participants visited once in each condition for a 15-minute exposure. Generally, participants’ psychological immersion and presence outcomes were higher in the VR headset and virtual nature room conditions than in the TV condition. Psychological immersion and presence outcomes were higher in the VR headset condition than in the virtual nature room condition. In terms of VR sickness, there were some interesting findings depending on the measured subscale (oculomotor and disorientation). We also unpack and provide an exemplar on how to use the terms technological immersion, psychological immersion, and presence in virtual environment research.

    Mitigating climate change and halting biodiversity loss require sustainable after-use strategies for peat extraction sites. This study evaluates the climate regulation potential of post-extraction land use using two peat cutaway sites in South Ostrobothnia, Finland, as case examples. The land use portfolio examined includes afforestation (conventional and short-rotation), peatland restoration, creation of open-water wetlands, conventional agriculture, reed canary grass cultivation and paludiculture. First, we mapped all suitable areas for each land use at the two case study sites, based on detailed spatial data on surface elevation, peat thickness and subsoil characteristics. Second, we calculated the climate warming impact of each land use based on published greenhouse gas flux and biomass estimates using REFUGE4, a climate impact model. Third, we assessed the climate impact of land-use scenarios aligned with five different objectives: climate regulation, ecological restoration, food production, timber production, and peat-replacing biomass production. This allowed us to explore how landowners’ preferences or policy choices may influence climate outcomes. The results suggest that various climate-wise land use combinations are feasible after peat extraction, depending on site-specific conditions and landowner and policy preferences. We propose that tailoring land use to site characteristics and using strategic damming and ditching to create a multi-habitat landscape can provide both economic and ecological benefits. However, substantial knowledge gaps remain regarding greenhouse gas fluxes from post-extraction land uses.
