“…Excess Zn (Table 1) can cause the induced Fe loss. The presence of Zn inhibits the metabolism of Fe, causing the appearance of symptoms of induced Fe deficiency, which in severe cases is characterized by decreased chlorophyll levels, resulting in totally chlorotic leaves (Romheld, 2001;Izaguirre-Mayoral & Sinclair, 2005;Ghasemi-Fasaei & Ronaghi, 2008).…”

RESUMO Toxicidade por metais pesados em plantas de arroz e soja cultivados em solo contaminadoOs metais pesados podem-se acumular no solo, causando fitotoxicidade em plantas, apresentando alguns sintomas específicos. Por esta razão, este estudo avaliou os sintomas específicos, em plantas de arroz e de soja, causados por excesso de metais pesados no solo. As plantas de arroz e de soja foram cultivadas em vasos, contendo solos com diferentes quantidades de metais pesados. O delineamento experimental foi inteiramente casualizado, com quatro repetições, utilizando-se duas culturas e sete amostras de solos com diferentes níveis de contaminação. As plantas de arroz e de soja exibiram diferentes respostas às elevadas concentrações desses metais no solo. Por exemplo, altas concentrações de Zn disponível no solo causaram fitotoxicidade no arroz e na soja, principalmente cloroses e inibição do crescimento das plantas. As plantas de arroz acumularam maiores teores de Cu, Mn, Pb e Zn e foram mais sensíveis às concentrações elevadas desses elementos no solo, absorvendo-os mais facilmente do que as plantas de soja. Além disso, altas concentrações de Zn no solo reduziram a concentração de Fe na parte aérea das plantas de soja e de arroz para níveis considerados deficientes.Palavras-chave: contaminação, nutrição de plantas, sintomatologia, metal pesado, Oriza sativa L., Glycine max L.1 Engenheira-Agrônoma.

The present study evaluated the specific symptoms on rice and soybeans plants caused by excess of heavy metals in soil. Rice and soybean were grown in pots containing soil with different levels of heavy metals. A completely randomized design was used, with four replications, using two crop species and seven sample soils with different contamination levels. Rice and soybean exhibited different responses to the high concentrations of heavy metals in the soil. Rice plants accumulated higher Cu, Mn, Pb and Zn concentrations and were more sensitive to high concentrations of these elements in the soil, absorbing them more easily compared to the soybean plants. However, high available Zn concentrations in the soil caused phytotoxicity symptoms in rice and soybean, mainly chlorosis and inhibited plant growth. Further, high Zn concentrations in the soil reduced the Fe concentrat...

“…This process can involve competition among the micronutrient ions for entry into the plant, so that an otherwise beneficial process of nutrient accumulation becomes a limiting factor for efficient utilization of specific micronutrients (Cohen et al 1997;Alam et al 2001;Kim and Guerinot 2007;Ghasemi-Fasaei and Ronaghi 2008;Rietra et al 2015). Here, we will briefly highlight how micronutrients' uptake mechanisms can affect their accumulation in the plant. )…”

Micronutrients are essential mineral elements required for both plant and human development. However, micronutrients are often lacking in soils, crop, and food. Micronutrients are therefore used as fertilizer to increase crop productivity, especially when the application of conventional NPK fertilizers is not efficient. Here, we review the application of micronutrients in crop production. Reports show that micronutrients enhance crop nutritional quality, crop yield, biomass production, and resiliency to drought, pest, and diseases. These positive effects range from 10 to 70 %, dependent on the micronutrient, and occur with or without NPK fertilization. We discuss the uptake by plants of micronutrients as nanosize particulate materials, relative to conventional uptake of ionic nutrients. We also show that packaging of micronutrients as nanoparticles could have more profound effects on crop responses and fertilizer use efficiency, compared to conventional salts or bulk oxides.

“…Like to iron, zinc deficiencies are mainly found on sandy soils low in organic matter and on alkaline soils. Uptake of zinc also is adversely affected by high pH, high levels of available phosphorus and iron in soils (Ghasemi-Fasaei and Ronaghi, 2008).…”

Nano-fertilizers are new generation of the synthetic fertilizers which contain readily available nutrients in nano scale range. Nano fertilizers are preferred largely due to their efficiency and environment friendly nature compared to conventional chemical fertilizers. To evaluate the effects of foliar spray of micronutrient nano-fertilizer (iron and zinc) and nano-titanium dioxide (nTiO2) solution on grain yield and its components in barley under supplemental irrigation conditions, a field experiment was carried out in the semi-arid highland region of Maragheh, Iran. Barley plants were separately treated with of chelated nano-scale zinc oxide (ZnO) and ferric oxide (Fe2O3) suspensions during tillering stage, booting and milky stages. Results revealed that days to anthesis and maturity significantly increased after application of both nano-fertilizers. Furthermore, a considerable improvement was observed in grain mass, spike length, number of the grains per spike, chlorophyll content, grain yield and harvest index by application of nano-fertilizer. However the impact of nano zinc fertilizer was more prominent than iron. Foliar application of nTiO2 positively affected some morphophysiological characteristics like as days to anthesis, chlorophyll content and straw yield. The results suggest that the delivery of Zn into barley seedling through spray of nano-fertilizer can be an efficient nutrient management strategy in semi-arid regions. Overall, our result indicated that the integration of nanotechnology in fertilizer products can improve fertilizer use efficiency and significantly increase of barley yield. However, plant response to nanoparticles significantly depend on concentration and time of application as well as size, shape, and surface functionalization of the particles.
