“…The characteristic peaks of OCNF were observed at 22.73° (main peak) with two small peaks at 15.05 and 16.50° corresponding to (200), (11̅0), and (110) crystal planes, respectively. This XRD pattern is in complete accordance with the literature. , Furthermore, no significant changes in the structure of MH were observed after the incorporation of 5 wt % OCNF. The absence of distinguished diffraction peaks of OCNF indicates a good dispersion of the nanofibers in the matrix with the preservation of the amorphous nature of the MH material.…”

Even if substantial efforts have been made to produce coated fertilizers with more efficient nutrients release, the development of simple processes using greener materials is still challenging to date. Herein, designed biobased formulations, prepared using biochar materials and oxidized cellulose nanofibers filled into methyl hydroxyethyl cellulose, were developed and then used as coating agents of phosphate fertilizer (triple superphosphate). Biochars were elaborated via direct pyrolysis of lignocellulosic biomass. In the case of the so-called engineered biochar (i.e., montmorillonite modified), a co-pyrolysis process of montmorillonite (MT) and biomass was performed. Nanocomposite films were then prepared from the as-prepared coating formulations prior to examine their surface wetting, swelling capacity, and biodegradability in the soil medium. Collected results show that biochar materials significantly reduce the hydrophilicity of cellulosic materials. Furthermore, the addition of MT during the biomass pyrolysis impacts reaction yield (by 54.54%) and also tunes the porous structure of biochar. Moreover, this MT addition induces a decrease of the swelling capacity and degradation rate of cellulose/biochar films by a factor of 45.74 and 44.48%, respectively. Interestingly, the developed cellulose/ engineered biochar coating material induces an increase of the crushing strength of fertilizer granules by 30.29% in comparison with the uncoated fertilizer. Furthermore, the soil water holding capacity was also considerably improved by 7.78% with a water retention capacity of 3.00% after 25 days when cellulose/engineered biochar-coated fertilizer was added into the soil. In fact, this fertilizer impacts considerably on the release of phosphorus (P) in the soil with a reduction of 43.90% of P leaching within 80 days of soil incubation. These findings indicate that the biobased developed nanocomposite formulations of cellulosic biochars are suitable to produce slow-release phosphate fertilizers with reduced P leaching and water-saving properties.

“…Recently, the MIL-100(Fe)@CNF hydrogel (MC) based on TEMPO-oxidized cellulose nanofibers (CNFs) was used for the slow release of fertilizers. The hydrogels had a positive influence on wheat crop growth . MIL-125-NH 2 is a common MOF based on titanium metal ions, which has been used as a photocatalyst in the visible region due to its low band gap. − The present work focuses mainly on various postsynthetic routes of MOFs and their utility for plant growth and development, as well as the development of oil crop yield production under heat stress.…”

Climate change can affect the characteristics of various crops, such as biomass production, phenology, and physiology. Heat stress is one of the critical environmental factors for climate change; here, Sesamum indicum L. was planted in the field under heat stress of El-Wadi El-Gedeed conditions. To overcome the loss in seed yield and oil contents, the titanium–organic framework (MIL-125-NH2) can be modified with a free amino group in the network backbone using polyamines such as putrescine (Put), spermidine (Spd), and spermine (Spr) through a cross-linker with the phosphoryl group. The modified materials were sprayed on the vegetative part of S. indicum L., and the obtained results showed that the prepared materials have excellent performance toward growth parameters, added chemical components, and crop yield. The weight of sesame seeds obtained after treatment with Put@MIL-125-NH2, Spr@MIL-125-NH2, and Spd@MIL-125-NH2 showed an increase that is 1.39, 1.92, and 2.16 times that of the control experiment. The finding results support sustainable modern agriculture.
