The demand for bioenergy resources continues to grow due to increased emerging economic value and emission trading systems. On top of that, energy crop (EC) resources are key to addressing the interconnected global challenges of sustainable development with the adoption of Renewable Portfolio Standard (RPS) and the post-Paris Agreement in Korea. Current research on interactions between EC and plant growth-promoting rhizobacteria (PGPR) emphasizes the energy potential regarding greatly enhanced ecological and economic effects that may increase in the future. However, less attention has been focused on soil fertility management after crop planting in reclaimed tidal land using bio-fertilizers such as rhizobacteria. This review paper documented and evaluated the potential of ECs by discussing the evidence for interactions between PGPR and crops where representative species have grown on Korean reclaimed land during the recent decade. The existing literature revealed several important generalizations that emerge from this synthesis of mechanisms and interaction. First, EC-PGPR interactions affect the increase of biomass yield on reclaimed land without a decrease in values of soil and crop quality. Second, PGPR Bacillus subtilis JS increased the T-N (total nitrogen), P (phosphorus), and chlorophyll contents owing to mineral nutrient solubilization and chlorophyll a/b binding protein, and B. licheniformis MH48 affected the increase of the T-N and P contents in soil because of N fixation. In this respect, this scoping review highlighted that short-rotation plantation management through PGPR in reclaimed tidal land may be more sustainable than chemical fertilizer treatment in the context of land-use change.
由于新兴经济价值的增加和排放交易系统，对生物能源资源的需求持续增长。除此之外，能源作物（EC）资源对于韩国通过采用可再生能源配额制度（RPS）和《巴黎协定》后应对可持续发展的相互关联的全球挑战至关重要。目前关于EC与植物促生根际细菌（PGPR）相互作用的研究强调了其在未来可能增强的生态和经济效应方面的能源潜力。然而，对于在开垦的潮滩土地上使用根际细菌等生物肥料进行作物种植后的土壤肥力管理关注较少。本文通过讨论近十年来在韩国开垦土地上代表性物种生长的PGPR与作物之间相互作用的证据，记录并评估了EC的潜力。现有文献揭示了从这种机制和相互作用的综合中得出的几个重要概括。首先，EC-PGPR相互作用影响开垦土地上生物量产量的增加，而不会降低土壤和作物质量的值。其次，PGPR枯草芽孢杆菌JS由于矿物养分溶解和叶绿素a/b结合蛋白而增加了总氮（T-N）、磷（P）和叶绿素含量，地衣芽孢杆菌MH48由于固氮作用影响了土壤中T-N和P含量的增加。在这方面，本综述强调，在土地利用变化的背景下，通过PGPR在开垦的潮滩土地上进行短轮伐期种植管理可能比化肥处理更具可持续性。
