“…Nitrogen and iron (Fe) are essential to the proper functioning of the photosynthetic apparatus, and Fe is required for the uptake, transport, and assimilation participating in the N metabolism pathway [61,62]. The basil plants absorbed more Fe as the deprivation of N to cope with the disequilibrium of nutrition [63]. Similar results were obtained that the Cu contents were improved when N was omitted and P was omitted (Figure 5F).…”

Basil (Ocimum basilicum L.) contains abundant nutrients and is considered an economically important edible vegetable. The optimal nutrient levels will increase the productivity and basil quality. However, prominent research on basil regarding the diagnostic nutrient deficiency standard and the corresponding nutrient uptake is still scarce. To this end, the basil plants were hydroponically cultured and subjected to one of 14 nutrient solution treatments, corresponding to the omission of a single nutrient element (designated as -N, -P, -K, -Ca, -Mg, -NH4+, -NO3−, -S, -Fe, -Mn, -B, -Zn, -Mo, and -Cu) and a complete nutrient solution (CS) as the control. The most common nutrient deficiency symptoms were chlorosis, stunted roots and growth, and even leaf necrosis and abscission, in particular of -N, -P, -NO3−, and -Fe. We also found that basil is a NH4+-sensitive species. The photosynthetic capacity (photosynthesis pigments, Fv/Fm ratio, and greenness index) was disturbed to varying degrees when a single nutrient was omitted from the nutrient solution. Additionally, the omission of a specific single nutrient confers significant differences in the tissue nutrients, regardless of the macronutrients and micronutrients considered. Concomitantly, multivariate analysis suggested the correlations among certain important nutrients were distinctly different under different treatments (correlation analysis); the influences of different nutrient deficiencies on the tissue nutrient concentrations showed similarity (principal component analysis). Collectively, the growth, physiological, and biochemical changes studied in this trial not only improved our knowledge for diagnosing nutrient deficiency symptoms for practical cultivation but also provided a comprehensive understanding of the internal nutrient associations in basil.

“…For instance, Zn interaction with N is reported to be synergetic (positive) in various studies, so it has been observed in this case 40 , 41 . Considering the contrary reports by Ali et al 42 and Fageria 43 , the case of redox-active metal iron (Fe) the interaction appears to be complex. In addition, here in our experiment, neither the order of plant and grain iron (Fe) average concentration, i.e.…”

Nanotechnology appears to be a promising tool to redefine crop nutrition in the coming decades. However, the crucial interactions of nanomaterials with abiotic components of the environment like soil organic matter (SOM) and carbon‒sequestration may hold the key to sustainable crop nutrition, fortification, and climate change. Here, we investigated the use of sugar press mud (PM) mediated ZnO nanosynthesis for soil amendment and nutrient mobilisation under moderately alkaline conditions. The positively charged (+ 7.61 mv) ZnO sheet-like nanoparticles (~ 17 nm) from zinc sulphate at the optimum dose of (75 mg/kg blended with PM (1.4% w/w) were used in reinforcing the soil matrix for wheat growth. The results demonstrated improved agronomic parameters with (~ 24%) and (~ 19%) relative increases in yield and plant Zn content. Also, the soil solution phase interactions of the ZnO nanoparticles with the PM-induced soil colloidal carbon (− 27.9 mv and diameter 0.4864 μm) along with its other components have influenced the soil nutrient dynamics and mineral ecology at large. Interestingly, one such interaction seems to have reversed the known Zn-P interaction from negative to positive. Thus, the study offers a fresh insight into the possible correlations between nutrient interactions and soil carbon sequestration for climate-resilient crop productivity.

“…Fageria 51 , reported a decrease in Zn uptake in the wheat crops above 320 mM concentration of iron in a nutrient solution. Contrary to this, the study of Ali et al 54 , reported that the application of Fe (25 mg/kg) lead to a signi cant increase in Zn level in groundnut (Arachis hypogaea L.) crop. Nonetheless, detailed investigation still needs to be undertaken to unravel the interaction of Zn-Fe in a crop-speci c manner under given agronomic conditions.…”

Nanotechnology appears as a promising approach to revolutionize the fertilization industry in the coming decades. However, the crucial interactions of these nanomaterials with abiotic components of the environment like soil organic matter (SOM) and carbon- sequestration may hold the key to sustainable crop nutrition, fortification, and climate change. Here, we investigated the use of sugar press mud (PM) mediated ZnO nanosynthesis for soil amendment and nutrient mobilisation under moderately alkaline conditions. The positively charged (+ 7.61 mv) ZnO sheet-like nanoparticles (~ 17 nm) from zinc sulphate at the optimum dose of (75 mg/kg) blended with PM (1.4% w/w) were used in reinforcing the soil matrix for wheat growth. The results demonstrated improved agronomic parameters with (~ 47%) and (~ 30%) relative increase in yield and plant Zn content. Also, the soil solution phase interactions of the ZnO nanoparticles with the PM-induced soil colloidal carbon (-27.9 mv and diameter 0.4864 µm) along with its other components have influenced the soil nutrient dynamics and mineral ecology at large. Interestingly, one such interaction has reversed the known Zn-P interaction from negative to positive.
