“…Many methods can be used for the delivery of nanofertilizers to plants, which include: in vitro methods, which include in vitro culture media [89]; aeroponics and hydroponics [90]; and in vivo methods, which include soil and foliar applications [19,61]. There is a promising race in the production of different nanofertilizers globally that includes many nutrients, such as phosphate [24], copper [91], magnesium [92], iron [26], zinc [23], silicon [23], selenium [14,93], and sulfur [94].…”

The global food production for the worldwide population mainly depends on the huge contributions of the agricultural sector. The cultivated crops of foods need various elements or nutrients to complete their growth, and these are indirectly consumed by humans. During this production, several environmental constraints or stresses may cause losses in the global agricultural production. These obstacles may include abiotic and biotic stresses, which have already been studied in both individual and combined cases. However, there are very few studies on multiple stresses. On the basis of the myriad benefits of nanotechnology in agriculture, nanofertilizers (or nanonutrients) have become promising tools for agricultural sustainability. Nanofertilizers are also the proper solution to overcoming the environmental and health problems that can result from conventional fertilizers. The role of nanofertilizers has increased, especially under different environmental stresses, which can include individual, combined, and multiple stresses. The stresses are most commonly the result of nature; however, studies are still needed on the different stress levels. Nanofertilizers can play a crucial role in supporting cultivated plants under stress and in improving the plant yield, both quantitatively and qualitatively. Similar to other biological issues, many open-ended questions still require further investigation: Is the right time and era for nanofertilizers in agriculture? Will the nanofertilizers be the dominant source of nutrients in modern agriculture? Are nanofertilizers, and particularly biological synthesized ones, the magic solution for sustainable agriculture? What are the expected damages of multiple stresses on plants?

Photocatalytic Performance Improvement by Doping Ag on ZnO/MWCNTs Nanocomposite Prepared with Pulsed Laser Ablation Method Based Photocatalysts Degrading Rhodamine B Organic Pollutant Dye

ZnO/MWCNTs nanocomposite has significant potential in photocatalytic and environmental treatment. Unfortunately, its photocatalytic efficacy is not high enough due to its poor light absorbance and quick recombination of photo-generated carriers, which might be improved by incorporation with noble metal nanoparticles. Herein, Ag-doped ZnO/MWCNTs nanocomposite was prepared using a pulsed laser ablation approach in the liquid media and examined as a degradable catalyst for Rhodamine B. (RhB). Different techniques were used to confirm the formation of the nanostructured materials (ZnO and Ag) and the complete interaction between them and MWCNTs. X-ray diffraction pattern revealed the hexagonal wurtzite crystal structure of ZnO and Ag. Additionally, UV-visible absorption spectrum was used to study the change throughout the shift in the transition energies, which affected the photocatalytic degradation. Furthermore, the morphological investigation by a scanning electron microscope showed the successful embedding and decoration of ZnO and Ag on the outer surface of CNTs. Moreover, the oxidation state of the formed final nanocomposite was investigated via an X-ray photoelectron spectrometer. After that, the photocatalytic degradations of RhB were tested using the prepared catalysts. The results showed that utilizing Ag significantly impacted the photo degradation of RhB by lowering the charge carrier recombination, leading to 95% photocatalytic degradation after 12 min. The enhanced photocatalytic performance of the produced nanocomposite was attributed to the role of the Ag dopant in generating more active oxygen species. Moreover, the impacts of the catalyst amount, pH level, and contact time were discussed.

Increasing global population and urbanization demands enhanced food and feed crop production, but due to several reasons, the areas of fertile agricultural lands are reducing worldwide. The market of growing substrates, soil amendments, and improvers still is based on peat extraction and processing. Due to peat's fossil origin, it can be considered environmentally unfriendly and unsustainable. Seeking peat-substituting materials is of crucial importance on a global scale and may become a vitally significant assignment for future generations. The necessity for peat-free soil amendments is also directed by the targets of circular economy and environmental sustainability goals, leading to reducing or abandoning the use of fossil resources and paying attention to waste utilization as secondary raw material. This paper aims to discuss general features of peat-free soil amendments as well as provide efforts into the use of secondary raw materials such as biomass ashes for the elaboration of peat-free soil-improving products. As a case example, may serve a description of the peat-free product made by rotary drum granulation from biomass fly ashes (energy production waste) and local freshwater sediments in a mass ratio mixture of 67:100, optimally applicable for soil improvement at a rate of 50 g L -1 . Besides, regional opportunities in Indonesia and Latvia are referred. It was concluded that peat-free soil amendment elaboration can be better implemented on a regional scale after assessing agricultural needs, soil specifics, and available raw material variety applicable as ingredients in soil-improving products.
