This review focused on the behavior of ENPs and their transformations across various environmental compartments, including aggregation, oxidation, dissolution and vulcanization, which is essential for understanding their environmental fate, bioavailability and toxicity. The interactive mechanisms between both pristine and transformed ENPs and microorganisms or crop plants, as well as the negative and positive impacts of the transformed ENPs are discussed in details.

Soils were sampled from 20 farms under ORG and CON at 0–15 cm and 15–30 cm depths, with an uncultivated field as a reference. SOC pools and their derived indices were analyzed, with soil quality being evaluated using a minimum dataset and principal component analysis.

After one year of cultivating in the same field, replanting is unsuccessful for the next 8–10 years due to the accumulation of allelochemicals, deterioration of soil properties, and disruptions in soil microbial communities. These factors severely impact plant growth, quality, and overall soil health. This review examines the causes and adverse effects of CCO in <em>R. glutinosa</em> cultivation and evaluates various strategies to mitigate them. CCO arise from complex interactions between the plant root system, soil properties, and microbial communities. A key contributor is the accumulation of phenolic acids in the rhizosphere, which alters soil physicochemical properties and promotes the proliferation of root pathogens, including fungi and root-knot nematodes. This creates a self-reinforcing cycle of soil degradation and plant stress, exacerbating CCO. Approaches such as variety selection, optimized crop rotation patterns, and the application of plant growth-promoting rhizobacteria are discussed in the article. Additionally, soil disinfection techniques, including fumigation, organic amendments, flooding, and mulching, are reviewed for their potential to suppress pathogens and restore soil health. The role of biochar, compost, and beneficial microorganisms, applied individually or in combination, to alleviate CCO and improve soil conditions are also highlighted.
