The aim of the study was to determine the effect of soil contamination with arsenic on the concentration of iron in some plant species. In addition, the following arsenic neutralising substances were added to soil for tests: lime, dolomite, natural and synthetic zeolite, charcoal, loam and compost. Soil contamination with arsenic, application of neutralising substances to the soil as well as the crop species had significant influence on the content of iron in the tested plant organs. Soil contamination with arsenic had an antagonistic or synergistic effect on the content of iron in plants, which was closely related with the crop species. In a series without neutralising substances added to the soil, arsenic had a negative effect on the content of iron in the above-ground parts and roots of cocksfoot, roots of maize, grain, straw and roots of spring barley, but a positive influence on its accumulation in the above-ground parts of maize and roots of swede. The highest increase in the content of iron was found in the above-ground parts of maize. The application of inactivating substances to the soil significantly modified the content of iron in the tested plant organs. These substances caused a decrease in the concentration of iron in the above-ground parts of maize and cocksfoot, but led to an increase in the accumulation of this element in straw and roots of spring barley. The direction of change in the concentration of iron in plants, i.e. decrease or increase, following the application of arsenic neutralising substances depended on plant species and the tested organ as well as the type of substance added to the soil.

In the years 2005 and 2006, spring and autumn experiments were carried out with greenhouse lettuce ‘Michalina’ cultivar, which was fertilized with three iron chelates, i.e.: Fe-DTPA, Fe-EDTA+DTPA, Fe-AM-4 in the following doses (mg Fe·dm⁻³): 20 (control), 50, 75, 100 and 125. The objective of the work were the after effect of the mentioned chelates investigated in the autumnal experiments. Containers with peat that were used in spring experiments were stored in the greenhouse until autumn. In mid-September, lettuce seedlings were planted into the stored peat-filled containers after supplementation of the macro- and micro-elements with the exception of iron. No negative action of chelates was found. Plants yielded well without any symptoms of chelate excess which were observed in spring. After the application of the studied chelates, independent of the levels of Fe, the lettuce yields were similar. Increasing Fe levels, independent of chelates, were accompanied by a similar Fe content in leaves, by an increasing content of copper and decreasing contents of manganese and zinc.

Progressing urbanization results in the potential increase of pollution sources such as wastes, industrial or municipal sewage, which may contain hazardous inorganic pollutants such as e.g. metal ions and their compounds. Urbanization has a negative effect also on soil, as a consequence of an increasing share of impermeable surfaces such as pavements, parking lots, housing developments and public buildings. The area of a hardened (impermeable) surface is exposed to intensive surface runoff during rain and as a result pollutants are transported through the storm drainage system directly to surface waters. The aim of this study was to determine the effect of metals contained in rainwater discharged from subcatchments of various land use types on the quality of surface waters (the Cybina River and the Antoninek reservoir) in the city of Poznań, as well as investigate whether metal contents in rainwater effluents depend on the relief and character of the immediate catchment. Investigations were conducted in 2009 along the lower section of the Cybina River. Water samples from the river and reservoir were collected each time when collecting rain water samples. Water and sewage samples were collected 15 times within a year. Analyses were conducted on 5 selected catchments (with different land uses) drained by storm water drainage system discharged to the Cybina River and the Antoninek reservoir. Water was collected from 13 sampling points (5 of which were sewer outfalls and 8 were situated on the river or the reservoir above and below the sewage discharge). Higher concentrations of all tested elements were recorded in rainwater in comparison to the water samples coming from the river or the reservoir. Canonical Variate Analysis (CVA) model presenting differences between water concentrations of Cu, Zn, Cd, Pb and Fe and environmental variables (rainfall intensity measured in a four-point scale, location as divided into industrial areas multi- and single-family housing as well as location of sewage discharge to the river on the reservoir) showed elevated concentrations of these elements especially in water collected directly from the storm water sewer. Elevated metal concentrations in storm system effluents did not have a significant effect on the content of these pollutants in the river or the reservoir. It could have been caused by the intensive immobilization of elemental ions in bottom deposits followed by the metal uptake by aquatic organisms, mainly plants.

The impact of mineral fertilization with or without multi-component fertilizers on the content of microelements in soil and spring triticale grains was investigated in field trials, in 2009-2011. The experiment was carried out on 8 fertilizing treatments with three replications, which included two varieties of spring triticale: Andrus and Milewo. The content of available zinc and manganese was higher on plots cropped with the cultivar Andrus and nitrogen fertilization with urea or with urea and ammonium nitrate. It was also found out that the content of available manganese, zinc and iron in the analyzed soils was within the natural average range. A higher content of manganese and zinc in grains was detected after the application of multi-component fertilizers. Nitrogen fertilization at a dose of 120 kg.ha-1 together with Azofoska and Ekolist resulted in an increase in the iron content in cv. Andrus. The regression analysis between the content of the analyzed microelements in soil and in triticale grains revealed a significant increase in the iron, manganese and zinc content in grains together with an increase in the content of these elements in soil under cv. Milewo. With respect to the zinc content in soil and in grain from this variety, the coefficient of determination was the closest to the coefficient of a linear correlation (R2 = 0.9105). It was shown that an increase in the content of microelements in soil was not always accompanied by an increase in the content of these elements in spring triticale grains.

Background. Fortified food products contain usually higher amounts of certain nutrients. However, the information about the nutritional quality of such products is limited. The objective of this study was to determine the content and the release of iron from fortified and non-fortified food products available on the Polish market. Material and methods. A group of 29 fortified with Fe and non-fortified food products, such as cereal products (16) and confectionaries (13), were purchased from local market between October and November 2009. The content of Fe in these products, as well as the amount of Fe released in enzymatic digestion in vitro was determined by the flame atomic absorption spectrometry method. Results. It was found that most of the fortified with Fe food products had significantly higher amount and the potential bioavailability of this element in comparison with the non-fortified analogues, however the content of Fe determined analytically not always matched the values declared on the label. Conclusions. Products fortified with Fe appear to be better sources of potentially bioavailable Fe in comparison with the non-fortified analogues.

A greenhouse experiment aimed at investigating the effect of four chelates, differing in percentage of Fe content and the kind of Fe bonding ligand: Fe 8 Forte (EDTA+ +HEEDTA), Fe 9 Premium (DTPA), Fe 13 Top (EDTA) and Librel Fe DP7 (DTPA), on the state of iron nutrition of Merkury F1 cultivar greenhouse tomato grown traditionally in peat substrate. The second factor was iron content in the growing medium, which was established to reach the following levels: 50, 75 and 100 mg Fe⋅dm-3, while in the control object Fe values ranged 17.9 Fe⋅dm-3 (after peat liming). The experiment was established in a two-factorial design with three replications including four plants cultivated on one plot. The iron content was assayed in plant index parts according to the ASA method. On the basis of the results, significant differences were found in the state of greenhouse tomato nutrition under the influence of the examined iron chelates. The highest content of iron in tomato leaves was determined when chelate Fe 9 Premium (DTPA) was used, which points to the fact that it was the best source of Fe. The lowest iron level was recorded after the application of Fe 13 Top (EDTA). The highest mean Fe content for the years and dates of analyses appeared in leaves of plants cultivated in the growing medium containing 75 mg Fe⋅dm-3. In June, after the plants began to yield, there was a considerable decrease in the Fe content in plant index parts in comparison to the stage of fruit maturation and the end of yielding. The study did not demonstrate any symptoms of phytotoxicity or visible disorders regarding tomato growth and development due to the examined Fe chelates introduced in the doses of 32.1, 57.1 and 82.1 mg Fe⋅dm-3 to the substrate, whose initial Fe concentration after peat liming was on average 17.9 mg Fe⋅dm-3.

Micronutrient deficiencies have increased over recent decades due to the general depreciation of the quality of poor people’s diet, both in developed and developing countries. The deficiencies of iron (Fe) and zinc (Zn) are a critical public health problem worldwide, with the negative impact on health, lifespan and productivity. Biofortification is an agricultural approach that can improve human nutrition on a global scale. Agronomic biofortification is considered a short-term and complementary strategy, but economic analyses suggest that genetic biofortification is the most effective strategy for increasing dietary Fe and Zn intakes of vulnerable populations. Enrichment of cereal grains by breeding is a high-priority area of research, and an effective strategy among other approaches, e.g, fortification, supplementation and food diversification. This review discusses the role of Fe and Zn in plant nutrition, the potential strategies for developing Fe and Zn biofortified crops and their importance in human nutrition.

Research on grasslands is conducted to assess the yielding potential and determine changes of sward quality depending on applied fertilization. Therefore, the present study was undertaken to assess the contents of manganese, nickel and iron in soil and meadow sward shaped under the influence of diversified mineral fertilization and liming. The experiment is established in the village Czarny Potok near Krynica, about 720 m above sea level., at the foot of Mount Jaworzyna Krynicka. The experiment was set up in 1968 on a natural mountain meadow of mat-grass (Nardus stricta L.) and red fescue (Festuca rubra L.) type with a large share of dicotyledonous plants. Total content of manganese, nickel and iron was determined in the plant and soil material after sample mineralization in a muffle furnace. The studied were extracted with 0.025 mol·dm-3 NH4EDTA solution and the content of Mn, Ni and Fe in the solutions was assessed with the ICP-AES method. The content of total forms of manganese was higher in the soil of the limed series. The soil reaction significantly affected amounts of this element extracted with NH4EDTA solution. Soil liming limited manganese bioavailability and improved the forage value of the analyzed biomass. Small quantities of nickel bound to the soil organic substance were found in the analyzed soil, which suggested considerable mobility of this elements and its translocation into deeper levels of the soil profile, beyond the reach of the plant root system. Liming increased the content of iron forms in combinations with the soil organic substance. Iron deficiency in the meadow sward may have a physiological basis such as difficult iron transport from the root system to aerial plant parts, but it was not caused by limited iron uptake from soil.

Potato tubers obtained from a field experiment carried out in 2002-2004 were used for our analysis. The soil grain-size structure was that of light loamy sand. Two soil tillage systems were compared: conventional (ploughing + fall ploughing + harrowing + cultivating + harrowing) and simplified (reversing ploughing + cultivating). The second factor involved seven weeding methods such as application of the following herbicides: Plateen 41.5 WG, Plateen 41.5 WG + Fusilade Forte 150 EC, Plateen 41.5 WG + Fusilade Forte 150 EC + Atpolan 80 EC, Barox 460 SL, Barox 460 SL + Fusilade Forte 150 EC, Barox 460 SL + Fusilade Forte 150 EC + Atpolan 80 EC. Iron content and uptake with tuber yield significantly depended on the tillage practices and weeding methods as well as the weather conditions over the growing period. Conventionally tilled potato tubers had more iron, 65.80 g⋅kg-1 on average, than the tubers whose cultivation was based on simplified tillage, 64.82 g⋅kg-1 on average. The herbicides applied significantly increased the iron content and its uptake with tuber yield by an average 4.2 and 13.8%, respectively.

The aim of the study was to determine the effect of inoculation of Virginia mallow (Sida hermaphrodita [L.] Rusby) with fungus Sclerotinia sclerotiorum [Lib.] de Bary, which causes stem rot, on the contents and distribution of aluminium, manganese and iron in the shoots of this plant. Field study was carried out during three years (2011-2013) in the soil and weather conditions of central-west Poland. Inoculation was carried out with isolates obtained from rapeseed and mallow. It consisted in a slight damage of stem epidermis and inserting wheat grain overgrown with mycelium of a given isolate. During plant growth, strong infection of mallow shoots was observed, which caused inhibition in the growth and development of the plant. At the stage of technological maturity, shoots were harvested from both the control and inoculated plots for chemical analyses. Contents of the studied elements were determinated in analytical solutions obtained from biomass ash after its “dry combustion” method, using ICP-OES spectrometer. Contents and distribution of aluminium, manganese and iron in mallow shoots depended upon plant parts and placement of pathogens on the stem. The highest amount of aluminium was found in the inoculated part, and the lowest in the apices part, regardless of isolate origin. In the case of iron and manganese distribution, statistically significant effect of the applied pathogen was found. Isolate from the mallow caused greater manganese accumulation and lower iron accumulation. The conducted study demonstrates a significant effect of infection with fungus S. sclerotiorum on the physiological processes that occur in Virginia mallow plants.

W dwuletnich doświadczeniach wazonowych przeanalizowano zakres i kierunek zmian w zawartości i pobraniu żelaza przez rzepak i pszenicę w warunkach nawożenia roślin różnymi formami azotu i potasu. Do założenia eksperymentu wykorzystano materiał glebowy pobrany z warstwy ornej gleby bielicowej o składzie granulometrycznym piasku gliniastego lekkiego. Gleba ta charakteryzowała się niską zawartością przyswajalnego fosforu, potasu i siarki siarczanowej oraz bardzo niską magnezu przyswajalnego. Badania wykazały, że rzepak w porównaniu z pszenicą charakteryzował się wyższą zawartością oraz pobraniem żelaza. Większość tego mikroelementu kumulowała się w słomie roślin. Nawożenie roślin amonową formą azotu i chlorkową formą potasu wpływało na wzrost zawartości żelaza w roślinach. Najwięcej żelaza pobrał rzepak nawożony potasem w formie chlorkowej, a pszenica z serii nawożonej formą siarczanową tego składnika.

Intensively farmed rabbit does have higher nutritional requirements for minerals, especially Ca, P, Fe and Zn. Dietary trace element deficiency results in does mobilizing their body reserves to fulfil the demands for rapidly growing milk production and increasing bone mass of the developing foetuses. The aim of the study was to determine the effect of different trace element (Fe and Zn) supplements fed to intensively farmed rabbit does on the litter size, number of young rabbits reared to 35 days of age, and body weight on different days of rearing. Subjects were New Zealand White rabbit does assigned to two groups with 20 does per group and all of their offspring from 5 successive litters. Does from group I were fed a complete pelleted diet containing 1% premix (vitamin-mineral mixture), and those from group II received a mineral-vitamin premix with a 50% higher proportion of Fe and Zn. A higher Fe and Zn content of the diets for intensively farmed rabbit does increases the release of these trace elements into milk and has a significant effect on the litter size and litter weight on different days of rearing.
