Nanoparticles: The Plant Saviour under Abiotic Stresses

et al. 2022

Climate change significantly affects plant growth and productivity by causing different biotic and abiotic stresses to plants. Among the different abiotic stresses, at the top of the list are salinity, drought, temperature extremes, heavy metals and nutrient imbalances, which contribute to large yield losses of crops in various parts of the world, thereby leading to food insecurity issues. In the quest to improve plants’ abiotic stress tolerance, many promising techniques are being investigated. These include the use of nanoparticles, which have been shown to have a positive effect on plant performance under stress conditions. Nanoparticles can be used to deliver nutrients to plants, overcome plant diseases and pathogens, and sense and monitor trace elements that are present in soil by absorbing their signals. A better understanding of the mechanisms of nanoparticles that assist plants to cope with abiotic stresses will help towards the development of more long-term strategies against these stresses. However, the intensity of the challenge also warrants more immediate approaches to mitigate these stresses and enhance crop production in the short term. Therefore, this review provides an update of the responses (physiological, biochemical and molecular) of plants affected by nanoparticles under abiotic stress, and potentially effective strategies to enhance production. Taking into consideration all aspects, this review is intended to help researchers from different fields, such as plant science and nanoscience, to better understand possible innovative approaches to deal with abiotic stresses in agriculture.

Slurries are a problem for the food-producing industry. They are comprised of solid and liquid wastes which must be precipitated and packed in polymers, and then disposed of in special landfills. A package of chemical substances (TCAS-CATA) has been developed to control the smell of this type of material. However, questions arose as to whether it would have any effect on nutrient bioavailability after eliminating the odors. To this end, slurries from animal processing plants were treated with TCAS-CATA in different conditions, and the parameters of this resulting solution were measured. Our results indicate that the catalyst can increase 100% nitrogenated compound concentration (400 mg/L of nitrites and 250 mg/L of Nitrate). This nutrient liberation depends on the slurry source, i.e., slurries with shells generate fewer nitrogenated compounds, but deliver more calcium to the solution. The solution also generates germination in some seed types and can stimulate development in some types of plants. Finally, the catalyst reduces odor 100% without reducing the capacity of the slurry to deliver nutrients. Our data suggest that TCAS-CATA may be catalyzing the bioavailability of the compound from the slurry without requiring microbiological processes, which will reduce odor and permit the use of this slurry as a biological remediation, similar to what is achieved in composting systems, but without the associated thermophilic processes. Future studies will allow for more knowledge of the mechanism and handling industrial material for agricultural processes.

“…Controlled-release fertilizers (CRF), or smart fertilizers [1], are essential for future, environment-friendly agronomic activities [2][3][4][5][6][7][8][9]. The agricultural productivity needs to increase to match the growing demand for food, as food requirement is expected to increase by 50% by 2050 [4,10,11]. Eco-friendly agronomic activities and waste-free crop production are crucial to sustain the demand.…”

Mechanical Activation of Smectite-Based Nanocomposites for Creation of Smart Fertilizers

et al. 2022

This research presents the mechanical creation of smart fertilizers from a mixture of smectite and urea in a 3:2 ratio by using the planetary milling technique. The smectite–urea composites show intercalation between urea and mineral, which increases steadily with increasing activation time. A shift of X-Ray Diffraction basal reflections, intensities of Fourier transform infrared spectroscopy (FTIR) peaks, and weight losses in thermogravimetric analysis (TG) document the systematic crystallo-chemical changes of the composites related to nitrogen interaction with activation. Observations of the nanocomposites by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) corroborate the inference. Nitrogen intercalates with smectite in the interlayer space and remains absorbed either within micro-aggregates or on the surface of activated smectites. Soil leaching tests reveal a slower rate of nitrogen than that of traditional urea fertilizers. Different forms of nitrogen within the composites cause their differential release rates to the soil. The formulated nanocomposite fertilizer enhances the quality and quantity of oat yield.
