“…The reduction in soil pH (6.9, 6.3, 6.1, and 5.8 at N rates of 0, 28, 56, and 84 kg/ ha, respectively) would increase soil-Fe and Mn solubility and uptake by plants (Hodgson 1963 andHorvath 1972), thus explaining the increase in endogenous forage Fe and Mn values with increasing N fertilization rates ( Table I). The N fertilizer tended to retard morphological development and produced plants with large, thin leaves and larger leaf:stem ratio (Ryder and Sneva 1961).…”

Mineral analysis of forage from a nitrogen (N) fertilizer, field study produced unexpectedly high iron (Fe) concentrations which were correlated with the N fertilizer level (r2=.92) and the percentage N in the forage (r2 =.94). The high Fe values were presumed to be associated with dust on the leaves. The objective of this study was to determine the level of soil contamination on the forage sample and the contribution of mineral in the contaminant to that measured in the sample. Soil contamination of plant tissue samples was calculated from the dilution of soil titanium (Ti) assuming that the uncontaminated tissue contained 0 g Ti/g. Tissue harvested from the 0, 28, 56, or 84 kg N/ha treatments contained 23, 49, 48, and 60 mg soil/ g, respectively. Significant N fertilizer effects would have been accepted for each element tested if soil contamination had been ignored. Correcting for contamination resulted in significant N-fertilizer effects on the concentrations of sodium, potassium, manganese, iron, and zinc but not magnesium or calcium in the forage. Some of these effects may be explained by the acidifying effect of the N fertilizer source.

“…In addition, iron is also commonly used in various biochemical processes in microorganisms, animals and plants. For example, red blood in animals uses iron-containing hemoglobin for oxygen transport [3]. Iron has obvious isotopic differences before various reservoirs in nature, and can produce significant isotopic differences in celestial evolution, geochemistry, epigenetic environment, biochemistry and other processes.…”

Iron is an essential element for plant life activities, and is deeply involved in the material cycle of plant-water-soil. Therefore, it is necessary to understand the iron isotope behavior and fractionation law of iron in the cycle of plant-water-soil, to trace the migration and circulation of iron in the surface biosphere, and to trace the relationship between the biosphere where plants are located and the various plastids in nature. Issues such as interaction play an important role. This paper summarizes the representation methods and basic storage information of iron isotopes, and summarizes two different strategies for absorbing iron from soils and their characteristics of iron isotope fractionation. The results showed that when strategy I plants absorb iron, they will reduce ferric iron first, and absorb light iron isotopes preferentially; while strategy II plants absorb iron after chelating iron without obvious fractionation; some plants can have two iron isotopes at the same time. an absorption mechanism. Iron isotopes have great application potential in the research on the absorption mechanism of iron by plants, and may also have great prospects in future research scenarios such as iron transport in plants and iron distribution in tissues and organs.
