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

There is increasing pressure on global agricultural systems due to higher food demand, climate change, and environmental concerns. The design of nanostructures proposed as one the economically viable technological solutions that can make agrochemical use (fertilizers pesticides) more efficient through reduced runoff, increased foliar uptake bioavailability, decreased impacts. However, gaps in knowledge about transport nanoparticles across leaf surface their behavior planta limit rational for delivery with controlled fate limited risk. Here, current literature nano-objects deposited leaves reviewed. different possible routes (stomata, cuticle, trichomes, hydathodes, necrotic spots) are discussed, along paths translocation, via phloem, from end sinks (mature developing tissues, roots, rhizosphere). This review details interplays between morphological constraints, stimuli, physical-chemical properties influencing fate, transformation, after deposition. A metadata analysis existing highlighted plant used testing nanoparticle most often dicotyledon plants (75%), while monocotyledons (as cereals) less considered. Correlations parameters calculated indicated dose, size, zeta potential, affinity organic phases correlated leaf-to-sink demonstrating targeting specific compartments by should be achievable. also showed time growth seemed drivers mobility, largely overlooked literature. thus highlights material opportunities targeted, stimuli driven deliveries safe nanomaterials agriculture.

Facile Coating of Urea With Low-Dose ZnO Nanoparticles Promotes Wheat Performance and Enhances Zn Uptake Under Drought Stress

Frontiers in Plant Science, Год журнала: 2020, Номер 11

Опубликована: Фев. 26, 2020

Zinc oxide nanoparticles (ZnO-NPs) hold promise as novel fertilizer nutrients for crops. However, their ultra-small size could hinder large-scale field application due to potential drift, untimely dissolution or aggregation. In this study, urea was coated with ZnO-NPs (1%) bulk ZnO (2%) and evaluated in wheat (Triticum aestivum L.) a greenhouse, under drought (40% moisture capacity; FMC) non-drought (80% conditions, comparison not (control), separate ZnO-NP amendment. Plants were exposed ≤ 2.17 mg/kg 4.34 bulk-ZnO, indicating exposure higher rate of Zn from the ZnO. bulk-ZnO showed similar coating efficiencies 74-75%. Drought significantly (p 0.05) increased time panicle initiation, reduced grain yield, inhibited uptake Zn, nitrogen (N), phosphorus (P). Under drought, average initiation by 5 days, irrespective coating, relative control. contrast, did affect initiation. Compared control, yield significantly, 51 39%, ZnO-NP-coated uncoated urea. Yield increases bulk-ZnO-coated insignificant, compared both control treatments. Plant 24 8% ZnO-NPs; 78 10% bulk-ZnO. treatment reduce time, except Relative (irrespective coating) yield; enhanced significantly. fertilization N P uptake, regardless particle coating. Collectively, these findings demonstrate that enhances plant performance accumulation, thus potentiating field-scale deployment nano-scale micronutrients. Notably, lower inputs crop productivity, comparable This highlights key benefit nanofertilizers: reduction nutrient into agriculture without penalities.

Fertilizers for food and nutrition security in sub-Saharan Africa: An overview of soil health implications

Frontiers in Soil Science, Год журнала: 2023, Номер 3

Sub-Saharan Africa (SSA) faces chronic food insecurity associated with soil degradation and the peculiar aftermath of climate change exacerbated by rising population historically poor agricultural practices. Notably, use mineral fertilizers has potential to counteract in SSA; it drives an increased production required feed while sustaining quality health soils. However, limited financial resources deprive SSA promise fertilizers, wherein application rates are low, regimes characterized unbalanced nutrient composition fertilizer quality. Although current global is generally low efficiency, most affected due already usage available products. About 70% fertilizer-nitrogen lost through unregulated transformation ammonia, nitrous oxide, nitrate that either volatilized or emitted into atmosphere leached water bodies. Similarly, preponderance fertilizer-phosphorus via run-off leaching, unavailing plants overloading streams rivers and, together nitrate, causing eutrophication. These environmental problems accentuated where quantity issues a limiting factor. recent advances happening outside indicate nutrients, when strategically formulated, such as nano packaging, (bio)polymer encapsulation, tunable respond cues, can provide multiple outcomes, particularly, healthy soils higher productivity. Therefore, presumably, proper synthesis gamut properties influencing plant release availability, options for exposure uptake critical realizing these benefits SSA.

Опубликована: Июль 23, 2023

Nanotechnology-enabled fertilizers and pesticides, especially those capable of releasing plant nutrients or pesticide active ingredients (AIs) in a controlled manner, can effectively enhance crop nutrition protection while minimizing the environmental impacts agricultural activities. Herein, we review fundamentals recent advances nanofertilizers nanopesticides with controlled-release properties, enabled by nanocarriers responsive to biological stimuli, including pH change, temperature, light, redox conditions, presence enzymes. For pH-responsive nanocarriers, change induce structural changes degradation cleave bonding between nutrients/pesticide AIs nanocarriers. Similarly, temperature response typically involves higher temperatures accelerate release diffusion promoting bond breaking. Photothermal materials enable responses infrared photolabile moieties (e.g., o-nitrobenzyl azobenzene) are required for achieving ultraviolet light responses. Redox-responsive contain disulfide bonds ferric iron, whereas enzyme-responsive enzyme's substrate as building block. fabricating nanofertilizers, have been well explored, but only few studies reported temperature- In comparison, there more reports on nanopesticides, which range many dual- triple-responsiveness. Nano-enabled pesticides show tremendous potential enhancing utilization efficiency AIs. However, expand their practical applications, future research should focus optimizing performance under realistic lowering costs, addressing regulatory public concerns over safety risks.
