“…In addition, soybean plays a critical role in the global nitrogen cycle through biological nitrogen-fixation. , Soybean roots form symbiotic bacteroids with nitrogen-fixing bacteria in the nodules that convert atmospheric nitrogen to ammonia via in situ nitrogenase activity. , Importantly, the growth, yield, and nutritional quality of soybean are highly sensitive to Fe deficiency as it restricted the photosynthesis and nitrogenase activity . Recently, some published reports have indicated that foliar application of Fe-based NMs can lead to greater growth than conventional Fe chelates. − For example, Rahemi et al (2020) reported that foliar application of Fe-based NMs on quince ( Cydonia oblonga Mill.) leaves was more effective (1.34-fold) at alleviating chlorotic symptoms from Fe deficiency than were equivalent Fe chelates .…”

Sustainable strategies for the management of iron deficiency in agriculture are warranted because of the low use efficiency of commercial iron fertilizer, which confounds global food security and induces negative environmental consequences. The impact of foliar application of differently sized γ-Fe2O3 nanomaterials (NMs, 4–15, 8–30, and 40–215 nm) on the growth and physiology of soybean seedlings was investigated at different concentrations (10–100 mg/L). Importantly, the beneficial effects on soybean were size- and concentration-dependent. Foliar application with the smallest size γ-Fe2O3 NMs (S-Fe2O3 NMs, 4–15 nm, 30 mg/L) yielded the greatest growth promotion, significantly increasing the shoot and nodule biomass by 55.4 and 99.0%, respectively, which is 2.0- and 2.6-fold greater than the commercially available iron fertilizer (EDTA-Fe) with equivalent molar Fe. In addition, S-Fe2O3 NMs significantly enhanced soybean nitrogen fixation by 13.2% beyond that of EDTA-Fe. Mechanistically, transcriptomic and metabolomic analyses revealed that (1) S-Fe2O3 NMs increased carbon assimilation in nodules to supply more energy for nitrogen fixation; (2) S-Fe2O3 NMs activated the antioxidative system in nodules, with subsequent elimination of excess reactive oxygen species; (3) S-Fe2O3 NMs up-regulated the synthesis of cytokinin and down-regulated ethylene and jasmonic acid content in nodules, promoting nodule development and delaying nodule senescence. S-Fe2O3 NMs also improved 13.7% of the soybean yield and promoted the nutritional quality (e.g., free amino acid content) of the seeds as compared with EDTA-Fe with an equivalent Fe dose. Our findings demonstrate the significant potential of γ-Fe2O3 NMs as a high-efficiency and sustainable crop fertilizer strategy.

Iron (Fe) is necessary for plant growth and development. Iron deficiency disrupts major metabolic and cellular activities such as respiration, DNA synthesis, and chlorophyll synthesis. Iron also activates various metabolic pathways and is vital to numerous enzymes. Iron is widely distributed in soil, but plants do not readily absorb it. In addition to neutral pH, Fe also forms insoluble Fe complexes under alkaline conditions. The fundamental cause of Fe chlorosis is an imbalance between the solubility of Fe in soil and the demand for Fe by plants. Various Fe fertilizers, including organic, chelated, and inorganic, are administered to the soil and leaves to treat Fe deficiency and chlorosis. Currently, used Fe fertilizers are expensive, easily adsorb on soil particles, and cause Fe to leach out of the soil with water, thereby diminishing their efficiency. They also need to be applied repeatedly, resulting in an excessive Fe fertilizer concentration in the soil that can cause harm to the plants. The usage of Fe nanofertilizers in agricultural production has expanded to address the disadvantages of existing Fe fertilizers. The advantages of nanosized Fe fertilizers include their physical and chemical characteristics, such as the high surface area to volume ratio that aids in easy absorption by plants’ roots and leaves. Controlled‐release iron oxide nanofertilizers supply the regulated release of nutrients in a way that is coordinated with the nutritional needs of the crops. This improves the accumulation of nutrients in the plant, filling in the gap of nutrient deficiency and lowering environmental risks due to leaching. The possibility of iron oxide nanoparticles as Fe micronutrient fertilizers, their uptake and mechanism of action, advantages, and limitations are critically highlighted in this review article.
