Special Issue Information

Dear Colleagues,

This Special Issue focuses on innovative agricultural inputs and their ecological roles in soil–plant–microbe interactions, aiming to improve resource utilization and environmental resilience in modern agronomy. Contributions will explore how biodegradable materials, beneficial microbes, organic amendments, and plant diversification strategies affect soil nutrient cycling, crop productivity, and ecological remediation. By integrating agronomic practices with emerging biotechnologies and sustainable materials, this Issue provides a platform for interdisciplinary insights into enhancing agricultural sustainability. We welcome original research, reviews, and case studies that investigate the mechanistic pathways, field performance, and ecological trade-offs of such interventions.

Modern agriculture faces the dual challenge of increasing productivity while minimizing environmental footprints. Recent advances have introduced a suite of sustainable inputs—from biodegradable mulches and engineered microbes to organic waste reuse—that can reshape nutrient dynamics and ecosystem functions. These tools reflect a growing shift from conventional practices to ecologically informed agronomy.
This Issue aims to compile cutting-edge research on how various agricultural inputs—biodegradable materials, rhizosphere signals, beneficial microbes, and recycled organics—interact with soil and crop systems. It emphasizes field relevance, ecological functions, and sustainability performance, especially in diversified and intensive systems.

We seek novel contributions that explore the following:

  • The functional role of root exudates in plant–plant and plant–microbe interactions;
  • Biodegradable plastics and their impacts on soil health and crop traits;
  • Microbial degradation of organic pollutants and its agronomic relevance;
  • Organic waste (e.g., composted sludge) reuse in soil improvement and ecological remediation;
  • Original research articles with experimental or modeling approaches;
  • Field or greenhouse trials testing innovative materials or microbial technologies;
  • Review papers on emerging sustainable inputs in agronomy;
  • Mechanistic studies linking soil–microbe–plant processes;
  • Case studies with practical insights for sustainable agriculture.

Mining activities often result in ecosystem degradation and landscape destruction. The restoration of abandoned mine lands is particularly challenging due to the poor physicochemical properties and low fertility of the soil, which necessitate the use of soil amendments. Sewage sludge, which contains abundant nutrients, has potential for use in mine soil restoration. Four separate piles of sewage sludge, each weighing 5 tons, were subjected to aerobic composting and then applied at different rates (0%, 2%, 5%, 10%, and 20%) to reclaim an abandoned mine land site (500 m2). During the composting process, the pH, moisture content, organic matter (OM), and dissolved organic matter (DOM) of the sewage sludge all decreased, while electrical conductivity (EC) and germination index (GI) increased. The sewage sludge compost reached maturity after 83 days. Soil pH and bulk density decreased with increasing application levels, whereas soil fertility, such as OM, alkali-hydrolyzable nitrogen, available phosphorus (AP), and available potassium (AK), significantly improved after application of sewage sludge compost. Vegetation coverage (ryegrass and alfalfa) reached 100% after 2 months at the 20% application level. Fresh biomass and plant height were significantly higher at all application levels compared to the control (p < 0.05). Results from Pearson’s correlation, redundancy analysis (RDA), and the random forest model indicated that soil fertility, particularly AP, OM, and alkali-hydrolyzable nitrogen, rather than soil physicochemical properties, was the key factor influencing the restoration success of the mine site. The use of sewage sludge compost as a soil amendment for reclaiming abandoned mine lands is feasible and can help reduce the ecological restoration costs of mining. Full article

While root exudates play a crucial role in maintaining ecosystem balance and promoting plant growth, existing research primarily focuses on single ecosystems (e.g., field crops), with systematic investigations of their ecological functions in compound cropping systems, particularly nitrogen (N) cycling mechanisms in orchard multi-cropping systems, remaining limited. This review focuses on the N impact mechanisms mediated by plant root exudates in orchard ecosystems, emphasizing how root exudates optimize soil N activation, absorption, and utilization efficiency by modulating rhizosphere processes (e.g., nitrogen mineralization, root architecture remodeling). Studies indicate that the changes in orchard ecosystem function mediated by organic acids and flavonoids root exudates can significantly reduce nitrogen loss risks and increase the soil nitrogen turnover rate by lowering pH-activated nutrients, balancing the C:N ratio, and immobilizing microbial communities. This process also involves the coordinated regulation of nitrification, denitrification, and microbial fixation. Future research should prioritize investigating the interaction networks and regulatory mechanisms between root exudates of associated orchard crops and N-fixing microorganisms. This research direction will provide a scientific basis for improving the N use efficiency in orchard crops, optimizing fertilizer reduction techniques, and reducing chemical fertilizer usage, providing significant implications for achieving sustainable agricultural development. The theoretical support offers important scientific and practical value for advancing green and sustainable agriculture. Full article
