“…Unfortunately, this study did not compare the effect with water-soluble P or phosphate rock, nor was it conducted in actual soil. However, nano-hydroxyapatite increased P content of lettuce (13%), with a corresponding shoot biomass increase (11%), relative to H 3 PO 4 (Taşkın et al 2018). Foliar application of nano-hydroxyapatite on baobab (Adansonia digitata) seedlings increased leaf P content by 55 and 38%, compared with monoammonium phosphate or diammonium phosphate, leading to a leaf chlorophyll increase of 88 and 19%, and a dry biomass increase of 90 and 35%, respectively (Soliman et al 2016).…”

Mineral phosphorus (P) fertilizers support high crop yields and contribute to feeding the teeming global population. However, complex edaphic processes cause P to be immobilized in soil, hampering its timely and sufficient availability for uptake by plants. The resultant low use efficiency of current water-soluble P fertilizers creates significant environmental and human health problems. Current practices to increase P use efficiency have been inadequate to curtail these problems. We advocate for the understanding of plant physiological processes, such as physiological P requirement, storage of excess P as phytate, and plant uptake mechanisms, to identify novel ways of designing and delivering P fertilizers to plants for improved uptake. We note the importance and implications of the contrasting role of micronutrients such as zinc and iron in stimulating P availability under low soil P content, while inhibiting P uptake under high P fertilization; this could provide an avenue for managing P for plant use under different P fertilization regimes. We argue that the improvement of the nutritional value of crops, especially cereals, through reduced phytic acid and increased zinc and iron contents should be among the most important drivers toward the development of innovative fertilizer products and fertilization technologies. In this paper, we present various pathways in support of this argument. Retuning P fertilizer products and application strategies will contribute to fighting hunger and micronutrient deficiencies in humans. Moreover, direct soil P losses will be reduced as a result of improved P absorption by plants.

“…These evidences prompt the identification and preparation of new materials, where chemical doping, solubility and dissolution rates can be tuned to optimise (multi)nutrient release. 20,21 For this goal, biodegradable calcium phosphate nanoparticles have been proposed as promising phosphorus [22][23][24][25][26] 26 and N 7,20,27 fertilisers. These biodegradable nanoparticles can be also used as carriers for the controlled delivery of agrochemicals, such as humic substances 28 or urea.…”

Towards a more sustainable viticulture: foliar application of N‐doped calcium phosphate nanoparticles on Tempranillo grapes

et al. 2020

BACKGROUND The use of nanomaterials for the efficient delivery of active species in viticulture is still an unexplored opportunity. Nitrogen, an essential nutrient for grapevine development and wine quality, is commonly provided in the form of urea. However, the application of conventional fertilisers contributes to nitrate leaching and denitrification, thus polluting groundwater and causing a serious environmental impact. Nanotechnology is offering smart solutions towards more sustainable and efficient agriculture. In the present work, we assessed the efficiency of nontoxic amorphous calcium phosphate (ACP) nanoparticles as nanocarriers of urea (U‐ACP) through field experiments on Tempranillo grapevines. Four treatments were foliarly applied: U‐ACP nanofertiliser (0.4 kg N ha–1), commercial urea solutions at 3 and 6 kg N ha–1 (U3 and U6) and a control treatment (water). RESULTS The grapes harvested from plants treated with U‐ACP and U6 provided similar levels of yeast assimilable nitrogen, despite the very large reduction of nitrogen dosage. The concentration of amino acids was greater in U‐ACP‐treated plants than those of the control and U3 treatments and, barring a few exceptions, the values were comparable with those observed in grapes obtained following U6 treatment. Nanofertilisers provided a high arginine concentration in the musts but low proline concentrations in comparison to the U6 treatment. CONCLUSIONS The results of this work show the potential benefits of nanotechnology over conventional practices for nitrogen fertilisation. Significantly, the application of U‐ACP allowed a considerable reduction of nitrogen dosage to maintain the quality of the harvest, thereby mitigating the environmental impact. © 2020 Society of Chemical Industry

“…Investigations on the plant-soil system have generally highlighted a greater effectiveness of nano-scale P fertilizers with respect to conventional ones ( Bala et al, 2014 ; Liu and Lal, 2014 ; Sharonova et al, 2015 ; Soliman et al, 2016 ; Taşkın et al, 2018 ). On the other hand, hydroponically-grown tomatoes treated for 48 h with either nano-hydroxyapatite or its bulk counterpart revealed no significant difference in P content and other parameters linked to plant metabolism ( Marchiol et al, 2019 ).…”

FePO4 NPs Are an Efficient Nutritional Source for Plants: Combination of Nano-Material Properties and Metabolic Responses to Nutritional Deficiencies

et al. 2020

Phosphorous and iron are a macro- and micronutrient, respectively, whose low bioavailability can negatively affect crop productivity. There is ample evidence that the use of conventional P and Fe fertilizers has several environmental and economical disadvantages, but even though great expectations surround nanotechnology and its applications in the field of plant nutrition, little is known about the mechanisms underlying the uptake and use of these sub-micron particles (nanoparticles, NPs) by crop species. This work shows that cucumber and maize plants both use the nutrients borne by FePO 4 NPs more efficiently than those supplied as bulk. However, morpho-physiological parameters and nutrient content analyses reveal that while cucumber plants (a Strategy I species with regard to Fe acquisition) mainly use these NPs as a source of P, maize (a Strategy II species) uses them preferentially for Fe. TEM analyses of cucumber root specimens revealed no cell internalization of the NPs. On the other hand, electron-dense nanometric structures were evident in proximity of the root epidermal cell walls of the NP-treated plants, which after ESEM/EDAX analyses can be reasonably identified as iron-oxyhydroxide. It appears that the nutritional interaction between roots and NPs is strongly influenced by species-specific metabolic responses.
