Impact of engineered nanomaterials either alone or loaded with NPK on growth and productivity of French bean plants: Seed priming vs foliar application

Nanotechnology has become a solution to most of the problems facing humans nowadays. In agriculture, nanofertilizers play a pioneer role to enrich crop productivity and minimize environmental pollution problems. In this paper we investigate the possible effects of using two engineered nanomaterials nanochitosan (Cs) or carbon nanotubes (CNTs) either alone or loaded with NPK as fertilizers on French bean plants. The new approach used was to compare between two different methods of application: seed priming and foliar application. From the obtained results, it is apparent that foliar application is better than seed priming. This is evident from the improvement of growth, yield, and antioxidant system of plants and biochemical content of yielded seeds of foliar application than in seed priming as compared with control. In addition, foliar treatment shortened the days to harvest without reducing yield by 37.5% (80 days) as compared with control and seed priming treatment (110 days). Of interest, Cs nanoparticles appeared to improve growth and yield parameters more than CNTs in foliar application treatment. In conclusion, foliar application of nanofertilizers holds tremendous potential to improve crop productivity and we recommend the use of nanofertilizers as foliar application.

Influence of Hydroxyapatite Nanoparticles on Germination and Plant Metabolism of Tomato (Solanum lycopersicum L.): Preliminary Evidence

The Nutrient Use Efficiency in intensive agriculture is lower than 50% for macronutrients. This feature results in unsustainable financial and environmental costs. Nanofertilizers are a promising application of nanotechnology in agriculture. The use of nanofertilizers in an efficient and safe manner calls for knowledge about the actual effects of nanoproducts on the plant metabolism and eventually on the carrier release kinetics and nutrient accumulation. Hydroxyapatite (Ca10(PO4)6(OH)2) nanoparticles (nHA) have an interesting potential to be used as nanofertilizers. In this study, the effects of different nHA solutions stabilized with carboxymethylcellulose (CMC) were evaluated on germination, seedling growth, and metabolism of Solanum lycopersicum L., used as model species. Our observations showed that the percentage germination of S. lycopersicum is not influenced by increasing concentrations of nHa, while root elongation is strongly stimulated. Tomato plants grown in hydroponics in the presence of nHA have not suffered phytotoxic effects. We conclude that nHA had nontoxic effects on our model plant and therefore it could be used both as a P supplier and carrier of other elements and molecules.

Nanofertilizers vs. Biofertilizers: New Insights

Bio- and nano-fertilizers are one of the most important tools in modern agriculture and agri-food as well as a driving economic force in the near future. Also, bio- and nano-fertilizers also play an important role as promising methods for increasing use efficiency of different water and land resources, reducing environmental pollutions as well. So, environment friendly biotechnological approaches may offer alternatives to chemical fertilizers. Phosphurus, K and Zn solubilizer microbes are the most important microbial traits in soil biogeochemical cycles and plant growth promotion. The biosynthesis of nanomaterials using bacteria, algae, yeast, fungi, actinomycetes and plants has led to a new area of research for the formation of inorganic nanoparticles as eco-friendly fertilizers. Now, use of nanofertilizers in plant nutrition is one of the major roles of nanotechnology in agriculture and soil sciences. Thus, the application of biosynthesized nanoparticles in agricultural sector may lead to sustainable development. Hence, this leads to sustainable agriculture through putting less inputs and generating less wastes, minimizing nutrient losses, and release nutrients at a proper rate for plant demand comparing with conventional farming. There is very slight difference between bio- and nano-fertilizers depending on their mechanisms in the soil and plant, application methods, effective rates of addition as well as their impact on the environment. However, both nano-and bio-fertilizers and their interaction are needed further studies. Therefore, this review will focus on the new insights and a comparison between both nano- and bio-fertilizers.

Quantitative Understanding of Nanoparticle Uptake in Watermelon Plants.

The use of agrochemical-nutrient fertilizers has come under scrutiny in recent years due to concerns that they damage the ecosystem and endanger public health. Nanotechnology offers many possible interventions to mitigate these risks by use of nanofertilizers, nanopesticides, and nanosensors; and concurrently increases profitability, yields, and sustainability within the agricultural industry. Aerosol based foliar delivery of nanoparticles may help to enhance nanoparticle uptake and reduce environmental impacts of chemical fertilizers conventionally applied through a soil route. The purpose of this work was to study uptake, translocation, and accumulation of various gold nanostructures, 30–80 nm, delivered by aerosol application to a watermelon plant. Cellular uptake and accumulation of gold nanoparticles were quantified by Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS). Observations suggested that nanoparticles could be taken up by the plant through direct penetration and transport through the stomatal opening. Observed translocation of nanoparticles from leaf to root shows evidence that nanoparticles travel by the phloem transport mechanism. Accumulation and transport of nanoparticles depend on nanoparticle shape, application method, and nature of plant tissues.

Nanofertilizers – A Revolutionary Fertilizer for Sustainable Agriculture

Because of the inadequacy in arable lands and water resources, the improvement of agriculture segment is only promising by increasing of resources use efficiency with the least destruction to production bed through effective use of modern technologies. Among these, nanotechnology has the prospective to transform the agricultural structures, biomedicine, environmental engineering, safety and security, water resources, energy conversion, and various other areas. Nanostructured design through mechanisms such as targeted supply or slow/controlled release mechanisms and conditional release, could release their active constituents in reacting to environmental triggers and natural hassles more specifically. Studies indicates that the use of nanofertilizers causes an recovery in nutrients use efficiency, minimizes soil toxicity, curtails the forthcoming negative effects related with over dosage and reduces the frequency of the application. Hence, nanotechnology has a high potential for attaining sustainable agriculture, especially in emerging nations.
