“…[5,6] Controlled release formulation fertilizers compared to conventional fertilizers can overcome the loss of nutrients constraints, such as off stream losses, leaching, volatilization due to their more sustainable release characters and better uptake and stability. [7] A number of commercial coated fertilizer products with alkyd resin, polyurethane and polyolefin coating materials cannot degrade properly in soil solution phases, and thereby their accumulation in the soil destructs soil structure and consequently it fulminates the sustainable agricultures of arable lands. [8] Chitosan, the second great amount of natural polysaccharide on earth crust, as a compound of chitin deacetylation is a biodegradable and non-toxic material for environment.…”

The use of controlled release fertilizer (CRF) has become a new trend to minimize environmental pollution. In this study, urea-kaolinite containing 20 wt% urea after one hour dry grinding was mixed with different concentrations of chitosan as a binder to prepare nitrogen-based CRF. Fourier transform infrared spectroscopy confirmed the hydrogen bonding between urea and kaolinite. Covalent interaction between urea-kaolinite and chitosan make the granules stronger. The nitrogen release was measured in 5 days interval using a diacetylmonoxime calorimetric method at a wavelength of 527 nm. The results illustrated that by increasing the chitosan concentration from 3 to 7.5%, nitrogen release decreased from 41.23 to 25.25% after one day and from 77.31 to 59.27% after 30 days incubation in water. Compressive stress at break tests confirmed that granules with chitosan 6% had the highest resistance and were chosen for ammonia volatilization tests. Ammonia volatilization was carried out using the forced-draft technique for a period of 10 weeks. The results showed that the total amount of ammonia loss for conventional urea fertilizer and urea-kaolinite-chitosan granules was 68.63 and 56.75%, respectively. This controlled release product could be applied in agricultural crop production purpose due to its controlled solubility in the soil, high nutrient use efficiency and potential economic benefits.

“…Recently, not only nanosized gold particles, but also gold-coated mesoporous silica nanoparticles (Torney et al 2007) and gold-coated carbon nanoparticles (Vijayakumar et al 2010) have been developed and evaluated as carriers for delivering DNA, proteins, and chemical substances to plant target cells (Ghormade et al 2011;Moaveni et al 2011). Nanoparticles have also been assessed for delivering siRNA (Song et al 2010), vaccines, or chemical substances to mammalian cell (Rana et al 2011).…”

Plastid transformation methods have been developed for 20 plant species. However, only a few plant species, such as tobacco and lettuce, have been used in applied studies because transformation efficiencies are extremely low in other species. Plastid transformation has been mainly performed by particle bombardment using 0.6-µm gold particles as microcarriers of the transformation vector. Because the target materials in some plant species are undeveloped proplastids rather than fully developed chloroplasts, optimizing microcarrier size for the target size is a major consideration. In this study, we evaluated the availability of gold particles (0.07, 0.08, 0.1, 0.2, and 0.3 µm) that were smaller than those used for plastid transformation in previous studies. We obtained stable plastid transformants of tobacco with sufficient efficiency using all the tested small gold particles as the same level as 0.6-µm gold particles, even the smallest (0.07 µm). The average number of transformants obtained with 0.3-µm particles (9.3±4.6 per plate) was the highest among the tested gold particles. Because small gold particles were revealed to be sufficient for plastid transformation in a model tobacco plant, it is suggested that choosing appropriate small-sized gold particles which have never been used before will improve plastid transformation in many plant species.

“…Thus, using of these nanoparticles in cleaning the environment from pollutants is called nanoremediation. Many studies have been published concerning the benefits of nanoremediation or nanotechnology for environmental clean-up including heavy metals removing from soils (Ingle et al 2014;Araújo et al 2105;Jain et al 2015;Fajardo et al 2015;Jain et al 2016;Gillies et al 2016;Gil-Díaz et al 2016a;Martínez-Fernández et al 2017), using plants in clean up (Ghormade et al 2011;Capaldi Arruda et al 2015;Gil-Díaz et al 2016b;Martínez-Fernández et al 2017), remediation of waste water (Hamza et al 2016;Peeters et al 2016;De Luca and Ferrer 2017;Shekarriz et al 2017;Xue et al 2017) degradation of pesticides in soil and water (El-Temsah and Joner 2013;Gomes et al 2014;El-Temsah et al 2016;Kaushik and Djiwanti 2017). Nanoremediation of soils, as a promising strategy in minimizing the entry of pollutants in plant parts, can be performed using nanoparticles such as zero-valent iron nanoparticles (nZVI), ZnO, TiO 2 , carbon nanotubes, fullerenes and bimetallic nano-metals.…”

MANY global problems threaten our life on the Planet including climate changes, environmental pollution, food and soil security, energy crisis, etc. This environmental pollution has not only mainly serious risks and stress involving the human health and safety of the entire ecosystem but also the quantity and quality of crops productivity worldwide. Due to the great gap between the global food production and the global consumption, there is a crucial need to cultivate these contaminated lands sooner or later. Therefore, the removing of pollutants from soils and waters should be performed in frame of sustainable remediation and sustainable energy production accordingly. Depending on many factors (source and kind of pollutants, land use and the economics of water and soil resources, etc) many strategies should be addressed for the sustainable and integrated management of polluted lands. Nanoremediation is a promising strategy in controlling pollution and management. Three major applications of nanoremediation could be characterized including detection of pollution using nanosensors, prevention of pollution, purification and remediation of contamination. Further studies also concerning the impact of changing climate on the nanoremediation process in the agroecosystems should be considered. Thus, this review will focus on the evaluation of environmental nanoremediation and its strategy in polluted lands under climate changes. Using of nanotechnology in pollution control as well as the environmental pollution and its sustainable management also will be highlighted.Keywords: Environmental nanoremediation, Climate change, Pollution, Crop production, Environmental stress. IntroductionClimate changes are a great challenge facing the human kind as well as other living things. The production of crops and other agricultural features are extremely susceptible to changes in climate. So, these global changes will be caused major shifts in crop distribution due to climate changes in the future. Moreover, it has been estimated that climate changes are likely to reduce yields and/or damage crops in the 21 Removing of pollutants from soils and waters could be linked with both the sustainable remediation as well as sustainable energy production (Kovacs and Szemmelveisz 2017; Zheng and Shi 2017). Many strategies for the sustainable and integrated management of polluted lands should be addressed depending on several factors e.g., type of pollutants and their level, the purpose of land use after remediation, soil characterization and its topography, climate , cropping patterns and the availability of resources and their economics (El-Ramady et al. 2017;Saha et al. 2017a). Furthermore, a great debate concerning using of lands for crop food production (under growing global population) or energy crop production was and still for ages (Paschalidou et al. 2016). Therefore, a global and holistic strategy in facing the main three threats including hunger, lack of energy and pollution of environment as well as climate changes should be esta...
