“…Compared with the seed and leaf application methods, studies on soil Ni fertilization are more advanced, with a range of growing environments, soil classes and soybean genotypes having been evaluated previously (Table 3 ). It has been reported in the literature that this method improves N metabolism in soybean plants 18 , 19 , 32 , 37 , 53 , 54 , 57 , as found in this study (Figs. 1 b,d, 3 and 4 ).…”

“…1 a,c). This response can be explained by the dynamics of Ni in the soil; properties such as pH 37 , 53 , 55 , soil particle size 54 and organic matter 56 , 58 , which affect its availability to plants; and, consequently, the response to fertilization. The soil in edaphoclimatic environment 2, which was a sandier soil (Table 1 ), had a coarse grain size and was slightly reactive; therefore, it may have favored the mobility of Ni in the profile, possibly causing its loss by leaching 59 .…”

“…A benefit of this approach is that such doses may provide a residual effect for subsequent crops. Nevertheless, in the medium and long term, metals can accumulate in the trophic system 37 . Seed treatment with micronutrients is an option that would reduce the dose, which may reduce fertilizer costs and promote plant nutrition in the early growth phase when the poorly developed root system limits the absorption of nutrients from the soil.…”

Fertilization with nickel (Ni) can positively affect plant development due to the role of this micronutrient in nitrogen (N) metabolism, namely, through urease and NiFe-hydrogenase. Although the application of Ni is an emerging practice in modern agriculture, its effectiveness strongly depends on the chosen application method, making further research in this area essential. The individual and combined effects of different Ni application methods—seed treatment, leaf spraying and/or soil fertilization—were investigated in soybean plants under different edaphoclimatic conditions (field and greenhouse). Beneficial effects of the Soil, Soil + Leaf and Seed + Leaf treatments were observed, with gains of 7 to 20% in biological nitrogen fixation, 1.5-fold in ureides, 14% in shoot dry weight and yield increases of up to 1161 kg ha−1. All the Ni application methods resulted in a 1.1-fold increase in the SPAD index, a 1.2-fold increase in photosynthesis, a 1.4-fold increase in nitrogenase, and a 3.9-fold increase in urease activity. Edaphoclimatic conditions exerted a significant influence on the treatments. The integrated approaches, namely, leaf application in conjunction with soil or seed fertilization, were more effective for enhancing yield in soybean cultivation systems. The determination of the ideal method is crucial for ensuring optimal absorption and utilization of this micronutrient and thus a feasible and sustainable management technology. Further research is warranted to establish official guidelines for the application of Ni in agricultural practices.

Background and Aims In soybean production systems, increasing the efficiency of biological nitrogen fixation (BNF) is essential to ensure sustainability, which can be achieved through nutritional management. Fertilization with nickel (Ni) can positively affect BNF due to the role of this micronutrient in nitrogen (N) metabolism – urease and NiFe-hydrogenase. However, studies on Ni application methods are incipient. Our study aimed to investigate which Ni application method is most appropriate to promote soybean plant development, with an emphasis on BNF and N metabolism. Methods The isolated and combined effects of Ni application methods – seed treatment, leaf spraying and/or soil fertilization – were investigated in soybean plants grown under different edaphoclimatic conditions (field and greenhouse). Results Positive effects of the treatments Soil, Soil + Leaf and Seed + Leaf were observed, with gains of 7 to 20% in BNF, 1.5-fold in ureide, 14% in shoot dry weight and yield increases of up to 1,161 kg ha− 1. All Ni application methods increased the SPAD index, photosynthesis, nitrogenase and urease activity. The edaphoclimatic conditions, especially the soil classes, influenced the response of soybean to the Ni application methods. Conclusion The integrated Ni application methods, i.e., leaf spraying combined with soil or seed fertilization, as well as soil application alone, were more suitable to promote productivity in soybean cropping systems. The definition of the method is essential to ensure absorption and ideal use of this micronutrient, representing a viable and sustainable management technology. More studies are needed to elucidate an official recommendation for Ni in agriculture.

Background and aims Nickel (Ni) deficiency has been reported to occur in soybean (Glycine max) grown on leached tropical soils in Brazil. We aimed to determine whether an internal or external Ni supply can compensate for low Ni within the seed by assessing whether the amount of Ni in the seed whether the foliar-application of aqueous NiSO4 influenced the uptake of Ni by the leaf, the nutritional status of the plant, urease activity and growth. Methods We used Ni-depleted seeds (<0.35 μg Ni per g) and Ni-sufficient seeds (11.1 μg Ni g−1) for hydroponic experiments. Seedlings were grown either with or without an external Ni supply (0 or 0.85 μM Ni in nutrient solution) and either with or without an internal Ni supply (with or cotyledons removed). In addition, we used synchrotron-based micro-X-ray fluorescence analysis to examine the distribution of foliar-applied Ni (50 and 100 mg L-1). Key results Leaf Ni concentration and urease activity were both enhanced by increasing either the internal (cotyledon seed store) or external (solution) Ni supply. In addition, plants derived from Ni-depleted seed that received external Ni supply had 9.2% higher biomass relative to plants derived from Ni-sufficient seeds which received Ni. When foliar-applied, Ni accumulated in the pedicles of the trichomes within 15 minutes of application, and then moved to the vascular bundles before dispersing further into tissues within 3 hours. Conclusions Trichomes are an important pathway for foliar Ni absorption in soybean, but there are still major knowledge gaps our understanding of the physiological function of trichomes in the uptake of metal ions from foliar micro-nutrient treatments.
