“…Thus, the results suggest the effectiveness of potassium (K) and phosphorus (P) in increasing the size of leaves, favored by their homogeneous dispersion and distribution along the tubes together with controlled release by wax emulsion coating (Figure 1), as observed for multilayer fertilizer-infused mulch papers 31 and shell structured fibers obtained by electrospinning. 39 Although the dry mass variable was not measured, the results also suggest an increase in dry mass according to the treatments (T03 and T04) that present greater leaf length and width measurements. The increase in leaf dimensions provides greater effective area for plant synthesis, thus aiding their development and robustness.…”

Agricultural products such as seedling tubes are often made of nondegradable petroleum-based polymers. Little progress has been made in developing sustainable and active supports for seedling cultivation that enable acclimatization time reduction of certain seedlings. Thus, the aim of this work was to manufacture multimodal sheet tubes functionalized with fertilizers and hydrophobized with carnauba emulsion for pineapple seedling cultivation. Energy dispersive spectroscopy and flame atomic absorption spectrometry demonstrated the fibers’ homogeneous distribution and efficient release of nutrients. As a proof-of-concept, these tubes provided better development of pineapple seedlings in comparison to the control, increasing the number, length, and width of the seedlings’ leaves by more than 15%, 40%, and 50%, respectively. The coating with carnauba emulsion guaranteed the physical integrity of sheet tubes in the greenhouse until their planting. These findings may pave the way for a new alternative of sustainable agricultural supports for seedling cultivation.

New advances in nanotechnology are driving a wave of technology revolution impacting a broad range of areas in agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported in the last several years, focusing on mechanisms revealed for preparation and functioning. It appears to us that with many fundamental concepts have been demonstrated over last two decades, new advances in this area continue to expand mainly in three directions, i.e., efficiency improvement, material sustainability and environment-specific stimulation functionalities. It is also evident that environmental and health concerns associated with nano agrochemicals are the primary motivation and focus for most recent work. Challenges and perspectives for future development of nano agrochemicals are also discussed.

“…Nanofibers can apply for plant protection (through applying pesticides for pest control), plant growth (through applying hormones and/or fertilizers), pollution and contamination controls, and irrigation systems (through water filtration), as reported in Table 3 by Meraz-Dávila et al [56], Raja et al [57], and [58]. The main applications of nanofibers in the agricultural field may include coating seeds [60][61][62], nanofibers-based filters for irrigation systems [65], nanofibers for plant protection [56] through encapsulation of fungicides [66,67], or detecting trace some pesticides in water [69], nano-silica grafted fiber [70], smart nanotextiles for sustainable agriculture [13], nanofibers for encapsulation of agrochemicals including fertilizer [75], and phytohormones [71,72]. Nanofibers can be used as a smart and sustained delivery of agricultural inputs through seed to improve germination and seedling growth in rice [59,76] and cowpea [60], groundnut [57], and sesame [62].…”

Sustainable Applications of Nanofibers in Agriculture and Water Treatment: A Review

Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.
