“…Because different green manure species have different sensitivities to herbicides, they may lead to differences in herbicide transport and transformation processes. Mendes et al [87] used radio labelled herbicide technology to quantitatively analyze the ability of four green manure crops (Crotalaria spectabilis, Canavalia ensiformis, Stizolobium aterrimum, and Lupinus albus) to repair quinclorac-and tebuthiuron-contaminated soils, and the results showed that the four green manure crops have significant repairing effects on the two herbicides, and the repairing ability for tebuthiuron (4-22%) is higher than that for quinclorac (2-13%). Similarly, Taliane et al [88] used the same method to study the effects of six green manures (Canavalia ensiformes (L.) DC., Stilizobium aterrimum L., Raphanus sativus L., Crotalaria spectabilis RÖth, Lupinus albus L., and Pennisetum glaucum (L.) R.…”

Soil fertility management is one of the most important factors affecting crop production. The use of organic manures, including green manure, is an important strategy to maintain and/or improve soil fertility for sustainable crop production. Green manure generally refers to crops that can provide fertilizer sources for agricultural cash crops and improve soil productivity. The application of green manure is a traditional and valuable practice for agroecosystem management, particularly in paddy systems where green manure is rotated with rice. This paper systematically reviews the effects of green manure on soil microenvironments and greenhouse gas emissions, and the role of green manure in the phytoremediation of paddy fields. The paper concludes that green manure can not only affect soil nutrients and the microbial community, but also reduce greenhouse gas emissions and enhance soil remediation to some extent. Moreover, this review provides theoretical guidance on the selection of green manure germplasm and tillage methods for paddy fields of different climates and textures. However, this review only provides a macro-overview of the effects of green manure on soil nutrients, greenhouse gas emissions, and soil remediation in rice paddies based on a large number of previous studies, and does not provide a comprehensive quantitative assessment due to differences in green manure varieties and soil texture. The prospects for quantitative analysis of the ecological and economic effects of the sustainable development of green manure cultivation are discussed.

Background: Phytoremediation is a technique used in soils contaminated with residual herbicides, such as tebuthiuron. However, the herbicide presence in the soil and plant matrices are not generally quantified.Objective: This study aimed to select plant species to evaluate the phytoremediation of 14 C-tebuthiuron by showy rattlepod (Crotalaria spectabilis), sorghum (Sorghum bicolor), radish (Raphanus sativus), peanut (Arachis hypogaea), and alfalfa (Medicago sativa) in herbicide-contaminated soil. Methods: The selection of the five herbicide phytoremediation plants was with the application of five rates of tebuthiuron (300, 600, 1,200, 2,400, and 4,800 g a.i. ha -1 ) and compared to a control. Peanuts and sorghum (herbicide-tolerant plants) were sown in soil contaminated with tebuthiuron (600 g a.i. ha -1 ) applied through a working solution containing 17.47 kBq of 14 C-tebuthiuron. The total of herbicide was analyzed in the soil and plant at three phenological stages. Results: Showy rattlepod, radish, and alfalfa were sensitive to the herbicide even at the lowest application rate. Sorghum was tolerant to the herbicide up to 600 g ha -1 with the application of 1,200 g ha -1 , there was 80% injury; peanut was tolerant even at the highest rate (4,800 g ha -1 ) with only 40% injury. Peanut and sorghum were able to phytoremediate the soil, although, peanut was more efficient in decreasing tebuthiuron contamination by 76%, while sorghum reduced at by 45% at 3 rd phenological stage. Conclusions: Thus, both plants can be recommended in succession/ rotation with crops that had tebuthiuron applied from pre-emergence weed control.

“…Although tebuthiuron is not the focus of literature on pesticide depollution, we can find few contemporary examples of its successful bioremediation. Mendes et al 8 when studying the phytoremediation of pesticides by green manure, reported the ability for Crotalaria spectabilis , Canavalia ensiformis , Stizolobium aterrimum , and Lupinus albus to effectively remove C-tebuthiuron at 266.40 g ha −1 . Mucuna pruriens and Pennisetum glaucum were also able to dissipate C-tebuthiuron at 500 g ha −1 in soil with stillage as an organic matter to boost performance 9 .…”

“…Thus, phytoremediation proves useful to remediate tebuthiuron. However, it often requires a special management and makes it challenging for agricultural systems to produce food, energy and natural fiber in off-season 8 , 9 . Furthermore, it is not easy to simulate conditions on an industrial scale.…”

This study aimed to propose an eco-compatible strategy to mitigate the possible environmental contamination caused by tebuthiuron. Therefore, we screened potential tebuthiuron-degrading microorganisms from conventional (CS) and no-till (NTS) systems producing sugarcane. Then, they were bioprospected for their ability of decomposing the target-molecule at 2.48 mmol g−1 and 4.96 mmol g−1 into CO2 via respirometry. Integrating microbiota from CS and NTS into an advantageously synergistic bacterial pool produced the highest specific-growth rate of CO2 of 89.60 mg day−1, so outstripped the other inoculum. The bacterial CN-NTS framework notably stabilized the sigmoidal Gompertz curve on microbial degradation earliest and enabled the seeds of Lactucasativa to germinate healthiest throughout ecotoxicological bioassay for cross-validation. Our study is preliminary, but timely to provide knowledge of particular relevance to progress in the field's prominence in remediating terrestrial ecosystems where residual tebuthiuron can persist and contaminate. The analytical insights will act as an opening of solutions to develop high-throughput biotechnological strategies for environmental decontamination.
