“…Similarly to what is reported in our results, Zn-OMFs also affected the availability of nutrients in the soil and increased grain production of common beans, as well as the accumulation of Zn compared with ZnSO 4 . In our study, OMF1 was fertilized more efficiently in improved biomass production of maize plants, while in the Yellow Oxisol, the OMF3 was more efficient compared with Zn sulfate (Figure ).…”

“…When Zn is applied together with organic sources, as in OMFs, there is greater Zn use efficiency by plants. 7,16 The beneficial effects of organic sources and Zn are closely related to the complexation of zinc by organic molecules, 2,3,7 like it happens in Zn-HA interaction 4,10 and as it was verified through changes in the infrared spectrum. The water solubility of Zn-HA complexes depends on the chemical stability and reactivity of the humic-metal complexes formed, which are regulated by the stoichiometry of the Zn-HA mixture, pH, and HA properties.…”

Zinc (Zn) fertilization efficiency is often low in Oxisols due to the interaction of Zn with soil constituents and phosphorus (P). When Zn is supplied in soil fertilization as a complex via slow-release organomineral fertilizers (OMFs), it is less prone to react with soil constituents and P, thus increasing the efficiency of Zn supply to crops. However, obtaining effective synthesis routes for the production of enhanced-efficiency Zn-OMFs for Oxisols is still a challenge. In this study, we synthesized Zn-OMFs based on humic acid (HA) components in order to assess features concerning Zn complexation and release kinetics, as well as the agronomic performance of such products on biomass production, and Zn and P nutrition of maize and Brachiaria grass successively grown in two Oxisols with contrasting texture and soil organic matter (OM) content. Infrared analyses indicated that Zn was complexed in OMFs by sulfur and carbon groups, with kinetics studies showing that Zn is gradually released to soil from Zn-OMFs. Consequently, Zn diffusion and initial content in soil solution were reduced in Oxisols. At least one of the OMFs overperformed ZnSO 4 in terms of maize biomass production and Zn shoot accumulation. Moreover, residual effects of OMFs were greater than those of ZnSO 4 in Oxisols for Brachiaria grass cultivated after maize, with increases in biomass production and shoot Zn content varying depending on OMFs and Oxisol properties. A secondary effect of OMFs increasing P availability in the soil and P uptake by maize and Brachiaria grass plants was also noteworthy. Our findings showed that the overall agronomic performance was greater for OMFs when compared with ZnSO 4 , which is likely related to the slow release of nutrients by the synthetized OMFs due to Zn complexation by HA.

“…However, our result seemed closer to the study of ( Xiao et al., 2022 ), which reported little effect of GO exposure at doses 10 and 100 mg.L -1 on plant growth. Increased nutrient availability to lettuce plants, derived by GO and its physicochemical properties as reported ( Lahiani et al., 2015 ; Kabiri et al., 2017 ; Juarez-Maldonado et al., 2019 ; Carneiro et al., 2022 ), could have been one of the possible reasons. Another mechanism of beneficial interaction of GO and elemental sulfur could have been a positive effect on soil water retention as referred to by ( Zhao et al., 2020 ; Zhao et al., 2022 ).…”

“…GO is quite mobile in soil ( Sangani et al., 2019 ; Xia et al., 2021 ); however, its leaching can be reduced by aggregation mediated by Ca 2+ in concentration ≥ 0.5 mM ( Qi et al., 2014 ). Amendment of GO to soil alters its hygroscopic and adsorptive capabilities and water content, and reduces the impact of drought stress ( Zhao et al., 2020 ; Zhao et al., 2022 ); as a carrier, it increases the uptake of mineral micronutrients to plants via controlled release ( Kabiri et al., 2017 ; Li et al., 2019 ; Carneiro et al., 2022 ; Mohammadi Alagoz et al., 2022 ). These effects on soil nutritional traits are positive for plant growth and physiology ( Lahiani et al., 2015 ; Juarez-Maldonado et al., 2019 ) and GO may also benefit by protecting against other plant-harming factors ( Arikan et al., 2022 ).…”

The impact of graphene oxide (GO) nanocarbon on soil properties is mixed, with both negative and positive effects. Although it decreases the viability of some microbes, there are few studies on how its single amendment to soil or in combination with nanosized sulfur benefits soil microorganisms and nutrient transformation. Therefore, an eight-week pot experiment was carried out under controlled conditions (growth chamber with artificial light) in soil seeded with lettuce (Lactuca sativa) and amended with GO or nano-sulfur on their own or their several combinations. The following variants were tested: (I) Control, (II) GO, (III) Low nano-S + GO, (IV) High nano-S + GO, (V) Low nano-S, (VI) High nano-S. Results revealed no significant differences in soil pH, dry plant aboveground, and root biomass among all five amended variants and the control group. The greatest positive effect on soil respiration was observed when GO was used alone, and this effect remained significant even when it was combined with high nano-S. Low nano-S plus a GO dose negatively affected some of the soil respiration types: NAG_SIR, Tre_SIR, Ala_SIR, and Arg_SIR. Single GO application was found to enhance arylsulfatase activity, while the combination of high nano-S and GO not only enhanced arylsulfatase but also urease and phosphatase activity in the soil. The elemental nano-S probably counteracted the GO-mediated effect on organic carbon oxidation. We partially proved the hypothesis that GO-enhanced nano-S oxidation increases phosphatase activity.

“…Concerning micronutrients, although plant requirements for growth are substantially smaller, they can impact important plant processes such as photosynthesis. The only identified micronutrient study, realized in a highly weathered soil, 143 demonstrated that the addition of a small amount (<0.5%) of graphene oxide (GO) to biochar resulted in enhanced adsorption and retention of micronutrients (e.g., Zn). Thus, GNMs appear to harbor the potential to adsorb essential micro and macronutrients, enhancing their retention, especially for NO 3 − , within the soil rootzone.…”
