“…One mechanism involves acidifying the rhizosphere to make these metals more soluble and available for plant uptake (Tinker and Nye, 2000). In the case of Fe and Cu, plants and soil microbes can also exude ligands (e.g., siderophores) that bind these metals and make them available to plants for active uptake (Tinker, 1986). Most of the studies that have examined metallic ENP effects on plants have not included natural soil or microbial communities, and therefore the effects on nutrient availability and uptake in natural soil is unknown.…”

Recent evidence for the effects of metallic engineered nanoparticles (ENPs) on plants and plant systems was examined together with its implications for other constituents of the Society-Environment-Economy (SEE) system. In this study, we were particularly interested to determine whether or not metallic ENPs have both stimulatory and inhibitory effects upon plant performance. An emphasis was made to analyze the scientific evidence on investigations examining both types of effects in the same studies. Analysis of evidence demonstrated that metallic ENPs have both stimulatory and inhibitory effects mostly in well-controlled environments and soilless media. Nano zero-valent iron (nZVI) and Cu ENPs have potential for use as micronutrients for plant systems, keeping in mind the proper formulation at the right dose for each type of ENP. The concentration levels for the stimulatory effects of Cu ENPs are lower than for those for nZVI. Newer findings showed that extremely smaller concentrations of Au ENPs (smaller than those for nZVI and Cu ENPs) induce positive effects for plant growth, which is attributed to effects on secondary metabolites. Ag ENPs have demonstrated their usage as antimicrobial/pesticidal agents for plant protection; however, precautions should be taken to avoid higher concentrations not only for plant systems, but also, other constituents in the SEE. Further research is warranted to investigate the stimulatory and inhibitory effects of metallic ENPs in soil media in order to broaden the horizon of sustainable agriculture production in terms of higher and safer yields so as to meet the food requirements of human population.

“…The transformation from insoluble Mn(III) or Mn(IV) oxides to soluble Mn 2 + is highly dependent on environmental factors such as soil pH, moisture, nutrients, chloride, nitrification inhibitors, organic matter, and microbial activity (58,156). Thus, many of the factors predisposing plants to disease influence the availability of Mn in soil and may influence disease severity through their regulation of Mn uptake by the plant (24).…”

“…It should thus be possible on non-calcareous soils to prevent manganese deficiency by avoiding over-liming. It has been estimated that in the mid-1980's an area in England and Wales of 257,000 hectares received remedial sprays of manganese each year (Tinker, 1986). No systematic data appears to be available for Scottish crops but incidence of manganese deficiency in cereal crops appears to be substantial and to have increased in recent years (Sinclair, 1982).…”

A pot experiment was carried out in order to test the hypothesis that manganese nutrition of wheat was dependent on the phosphorus status of soil as well as on its pH and manganese status. An arable mineral soil whose lime and phosphorus status had been massively adjusted more than 18 years previously was compared with identical soil not so adjusted. Wheat plants were grown to maturity in these soils. Analyses were carried out on both soil and plant samples at intervals. Data for soil pH, soil solution concentrations of manganese and phosphorus, plant dry weight and tissue concentrations of manganese and phosphorus are presented. Concentrations of manganese were depressed in leaf tissue of plants from limed soils and also in high phosphorus soils. The depressed values for limed treatments were explained in terms of depressed soil solution manganese concentrations resulting from elevated pH. The results for high phosphorus soils could not be related to soil solution composition. It was suggested that high soil phosphorus resulted in elevated plant phosphorus which interfered in the uptake and/or translocation of manganese.
