“…The nitrogen accumulation for legumes green manure varies according with soil fertility, soil water availability and legumes species (Armstrong et al 2018, Wang et al 2018, Dayoub et al 2017, which may explain the low values of soil quality index for C. juncea. The low dry matter accumulation provided by P. glaucum re ected for low soil quality index for this species (Teó lo et al 2020).…”

Soil quality index shed light on soil health and its capacity to sustain high primary production. It also can assist decision-making in farming systems by integrating this valuable product into soil management planning. However, the currently existing models are based on rather local data, and thus, there is a lack of predictive tools to monitor soil quality on farming systems at tropical conditions. We characterized soil physico-chemical properties, plant biomass production under a 6-year experiment in a sandy soil from Tropical ecosystem, using ten treatments: Brachiaria decumbens, Canavalia ensiformis, Crotalaria juncea, Crotalaria ochroleuca, Crotalaria spectabilis, Lablab purpureus, Mucuna pruriens, Neonotonia wightii, Pennisetum glaucum, and Stilozobium aterrimum. We found that most of the soil physico-chemical properties were correlated with each other by Pearson’s correlation analysis. On the other hand, RDA illustrated that shoot dry biomass was related to soil C stock, K+, macro- and microporosity. Soil pH, Al3+, Ca2+, Mg2+, K+, Olsen’s P, Na+, soil C stock, bulk density, microporosity, macroporosity, and permanent wilting point were the main factors driving primary production in our long-term study. Our findings suggest that: 1) a consecutive green manure practice without any input of fertilizers after 6 years changed positively by increasing soil fertility (e.g., Ca2+, Mg2+, K+ and Olsen’s P), and improving plant growth and soil quality in tropical savanna climate conditions; and 2) the 33 multivariate predictive models may provide a deeper view about the benefits of using plant species as green manure by creating positive plant-soil feedback thus promoting soil quality.

“…The contamination of the environment by pesticides, including herbicides, is a major global concern and can be considered a major obstacle to the development of sustainable agriculture (Mendes et al, 2020). There is social and scientific appeal for the minimization of environmental impacts caused by the use of herbicides in the large areas cultivated with sugarcane and the increase of areas treated with long residual effect herbicides, such as tebuthiuron.…”

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.
