“…In the 21st century, agriculture has enormous challenges as the global population is rapidly expanding and is expected to reach over 9 billion people by 2050 [ 1 , 2 ]. Due to limited area, poor soil quality, and unavailability of water, the agricultural land area is not increasing proportionately with the increasing population but instead is diminishing.…”

“…However, plants can only utilize 30–35% of the total nitrogen available in the fertilizer due to their low nutrient uptake efficiency, and hence the substantial energy input is lost [ 3 , 5 , 6 ]. The major part of the unused nitrogen is swiftly digested by the microbes (bacteria, fungi, and protozoa) or lost to physical and chemical processes such as leaching and volatilization [ 1 ]. The loss of nitrogen through leaching causes the contamination of subsurface water bodies and poses a risk to aquatic life [ 5 ].…”

Recently, the development of sustainable and environmentally friendly biomaterials has gained the attention of researchers as potential alternatives to petroleum-based materials. Biomaterials are a promising candidate to mitigate sustainability issues due to their renewability, biodegradability, and cost-effectiveness. Thus, the purpose of this study is to explore a cost-effective biomaterial-based delivery system for delivering fertilizers to plants. To achieve this, rice straw (agro-waste) was selected as a raw material for the extraction of cellulose. The cellulose was extracted through alkali treatment (12% NaOH), followed by TEMPO-based oxidation. The cellulose nanofibers were characterized using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, and transmission electron microscopy. In scanning electron microscopy, a loosening of the fibrillar structure in cellulose nanofibers (CNFs) was observed with a diameter of 17 ± 4 nm. The CNFs were loaded with nitrogen-based fertilizer (ammonium chloride) in 1:1, 1:2, and 2:1 (w/w) proportions. The loading was estimated through surface charge variation; in the case of the 1:1 sample, maximum reductions in surface charge were seen from −42.0 mV to −12.8 mV due to the binding of positive ammonium ions. In the release kinetics study, a controlled release pattern was observed at 1:1, which showed a 58% cumulative release of ammonium ions within 8 days. Thus, the study paves the way for value-added uses of rice straw as an alternative to the current environmentally harmful practices.

In this work, a type of natural microspheric soil conditioner, PZ(Fe)/GL-SA-Urea, was prepared by emulsion cross-linking and sharp-hole coagulation bath methods. Gelatin (GL) and sodium alginate (SA) were selected as the outermost shell, and the prepared FeOOH was loaded on pickling zeolite (PZ) to improve the loading ratio of urea. The embedding performance and sustained release behavior of the microspheres showed that when the concentration of urea was 1.5%, the embedding rate reached 37.63%, and the cumulative release rate reached 68% within 100 h, indicating that the microsphere had good encapsulation and sustained release abilities. In addition, the water retention and swelling behaviors of the microspheres can be obtained by controlling the content of added GL. Furthermore, antibacterial and planting experiments revealed that the microspheres had excellent antibacterial effects and can effectively improve soil quality and promote crop growth. Therefore, the PZ(Fe)/GL-SA-Urea microsphere soil conditioners possess good application properties and provide fresh solutions to improve soil quality and raise crop yields.

“…However, several studies reported that a high content of urea fertilizers is lost due to leaching and ammonia volatilization upon application in soil, eventually generating severe environmental pollution, especially in soil and water sources. − Therefore, slow-release urea (SRU) development serves as a means to improve urea efficiency, enhance controllable usage, and minimize environmental pollution. Currently, SRU is commonly prepared by encapsulating or adsorbing a saturated urea solution to porous matrix media such as zeolites, − porous polymer composites, − or mesoporous materials − to control the urea release. Several polymers have been used as SRU matrix media, such as polyacrylonitrile, , polysulfone, poly(vinyl chloride), polyacrylic-rubber, poly(vinyl acetate), and polyurethane .…”

An effective method to prepare slow-release urea was developed with aminopropyl-functionalized mesoporous silica (MS) to achieve enhanced urea adsorption and slow-release properties. As a novel study, mesoporous silica was developed using treated geothermal silica as the silica source, cetyltrimethylammonium bromide (CTAB) as the surfactant, and 3-aminopropyl trimethoxy silane (APTMS) as the surface modification agent. Mesoporous silica with the most desirable properties of uniform micromorphology containing 38.55 wt % silica particles, 668.849 m 2 /g surface area, 149.33−353.28 mL/g adsorption−desorption range, and 0.26 mL/g adsorption pore volume was achieved using 0.05 mol of CTAB. The synthesized mesoporous silica showed type-IV hysteresis, which corresponds to mesoporous materials. Differential scanning calorimetry (DSC)−thermogravimetric analysis (TGA) thermograms showed that mesoporous silica is more reactive, with peaks at 82.3 and 159.5 °C, has good thermal stability, and undergoes only 17.61% weight loss until 124 °C. Scanning electron microscopy (SEM) showed that functionalization and urea adsorption to mesoporous silica resulted in no significant morphological changes. In the Fourier transform infrared (FTIR) spectra, MS/APTMS/U26.74 was observed to have higher intensities of CO, N−H, C−N, and C−H groups compared with other samples. The cumulative urea release during 7 days was 184.5 ppm (92.4%) for commercial urea and 124.6 ppm (64.4%) for MS/APTMS/U26.74. The Higuchi kinetic model yielded the best fit predicting MS/ APTMS/U26.74 release kinetics, with an R 2 of 0.9979 and a Higuchi constant of 24.4964%/day. Finally, MS/APTMS/U26.74 synthesized using geothermal silica, CTAB, and APTMS was noted to possess a potential composition for slow-release urea with enhanced efficiency.
