“…In our study, Fe 2 O 3 nanomaterials had no effect on fresh weight, and almost all concentration of these three Fe 2 O 3 NPs promoted the elongation of rice seedlings significantly,which coincided with previous report [12]. This positive effect could due to the the greater bioavailability of iron molecules to the seed radicals [13] and the the higher solubility of Fe 2 O 3 NPs in suspension [12]. Notebly, considering the different sizes, morphologies of NPs and differents plants species, the acquisition strategies of Fe elements as the nanoparticulates may not always effective [14].…”

“…No such differences were observed in the shoot levels of these nutrients, suggesting that the amount of Fe translocable from the root to shoot may be enough to match the Fe absorbed via leaves, without showing a suppression of the uptake and translocation of Cu, Mn, and Zn. In other studies, Alidoust and Isoda (2013) reported more positive responses (e.g., increased photosynthesis) to foliar, than to root-applied Fe in soybean. This contrasts with the study of Rodriguez-Lucena et al (2010) in a hydroponic system, where no foliar versus root differences were found in soybean, dependent on Fe chelate type.…”

Micronutrients are essential mineral elements required for both plant and human development. However, micronutrients are often lacking in soils, crop, and food. Micronutrients are therefore used as fertilizer to increase crop productivity, especially when the application of conventional NPK fertilizers is not efficient. Here, we review the application of micronutrients in crop production. Reports show that micronutrients enhance crop nutritional quality, crop yield, biomass production, and resiliency to drought, pest, and diseases. These positive effects range from 10 to 70 %, dependent on the micronutrient, and occur with or without NPK fertilization. We discuss the uptake by plants of micronutrients as nanosize particulate materials, relative to conventional uptake of ionic nutrients. We also show that packaging of micronutrients as nanoparticles could have more profound effects on crop responses and fertilizer use efficiency, compared to conventional salts or bulk oxides.

“…titanium, silicon, silver) and nanoforms of micronutrients such as Zn, Fe and Mn, have been demonstrated as being able to improve crop growth and/or content of these elements (Larue et al 2012;Wang et al 2013a, b, c;Siddique and Al-Whaibi 2014;Servin et al 2015). Often, the positive effects of nanoparticles (NPs) on crop growth occur to a greater extent than with the equivalent dose of the same mineral nutrient presented in ionic (salt) form (Alidoust and Isoda 2013;Pradhan et al 2013;Zhao et al 2013;Kim et al 2014), and when applied at the same concentration at relatively high doses, the concentration at which toxicity occurs is lower with ions than with NPs (Dimkpa et al 2012a;Pradhan et al 2013;Kim et al 2014). The enhanced beneficial effects of NPs are due likely to the fact that unlike ionic fertilisers where a significant portion of the nutrients could be lost due to the formation of phosphate and carbonate precipitates or other soil factors, exposure to NPs is potentially controlled by the sustained but low release of the functional ions from the particles which serve as reservoirs of ions (Dimkpa et al 2012b), with plant-adequate amounts then likely taken up to offset losses due to interaction of the released ions with soil factors.…”

Meeting human needs within the ecological limits of our planet calls for continuous reflection on, and redesigning of, agricultural technologies and practices. Such technologies include fertilisers, the discovery and use of which have been one of the key factors for increasing crop yield, agricultural productivity and food security. Fertiliser use comes, however, at an environmental cost, and fertilisers have also not been a very economically effective production factor to lift many poor farmers out of poverty, especially in African countries where application on poor soils of unbalanced compositions of nutrients in fertilisers has shown limited impact on yield increase. Agronomic practices to apply existing mineral fertilisers, primarily containing N, P and K, at the right time, the right place, in the right amount, and of the right composition can improve the use efficiency of fertilisers. However, the overall progress to reduce the negative side effects is inadequate for the desired transformation toward sustainable agriculture in poor countries. Globally, there have been no fundamental reflections about the role and functioning of mineral fertilisers over the past 5 decades or more, and compared to other sectors, dismal investments have been made in mineral fertiliser research and development (R&D).In this paper, we reflect on current fertilisers and propose a more deliberate adoption of knowledge of plant physiological processes-including the diversity of mineral nutrient uptake mechanisms, their translocation and metabolism-as an entry point in identifying the physicochemical "packaging" of nutrients, their composition, amount and timing of application to meet plant physiological needs for improved instantaneous uptake. In addition to delivery through the root, we suggest that efforts be redoubled with several other uptake avenues, which as of now are at best haphazard, for the delivery of nutrients to the plant, including above ground parts and seed coating. Furthermore, ecological processes, including nutrient-specific interactions in plant and soil, plantmicroorganism symbiosis, and nanotechnology, have to be exploited to enhance nutrient uptake. It is hoped that concerted R&D efforts will be pursued to achieve these strategies.
