The aim of conducted in years 2008-2012 studies was to assess the efficiency of application of increasing manganese levels on the nutritive value of tomato fruits (Lycopersicon esculentum Mill. cvs. ‘Alboney F1’ and ‘Emotion F1’), expressed in the contents of macro- and micronutrients. Plants were grown in rockwool with application of nutrient solution characterized the following chemical composition (in [mg dm–3]): N-NH4 2.2, N-NO3 - 230, P - 50, K - 430, Ca - 145, Mg - 65, Cl - 35, S-SO4 - 120, Fe - 2.48, Zn - 0.50, Cu - 0.07, pH -5.50, EC - 3.00 mS cm–1. The following manganese plant nutrition levels were examined (in mg Mn · dm–3): 0.06 (control), 0.3, 0.6, 1.2 (Experiment I), 2.4, 4.8, 9.6 and 19.2 (Experiment II); (denoted as Mn-0, Mn-0.3, Mn-0.6, Mn-1.2, Mn-2.4, Mn-4.8, Mn-9.6; Mn-19.2). The source of manganese was manganese sulfate (MnSO4 · H2O, 32.3% Mn). The nutritive value of tomato fruits changed significantly under the influence of the application of wide range of manganese concentrations. It was found a significant reduction of the content of phosphorus (Exp. I, II), potassium (Exp. II), calcium (Exp. I, II) and magnesium (Exp. I, II). Manganese influence on the decreasing content of other metallic micronutrients (Fe, Zn, Cu) in fruits. Cultivar had a significantly influence on the content of: nitrogen (except Mn-2.4, Mn-4.8, Mn-9.6), potassium (in Exp. II, except Mn-4.8), calcium (except for Mn-0.6, Mn-2.4), magnesium (except Mn-0.3 and Mn-2.4), iron (except Mn-1.2), manganese and zinc (except control combination) and copper (except Mn-0.6 and Mn-1.2). The highest contents of N, Ca and Mg in fruits were recorded for the application of Mn-0, while for P and K - at 0.3 mg Mn dm–3, whereas it was lowest for all these nutrients (except N) in the case of Mn-19.2 (Exp. II). The reduction of nutrient contents amounted to (% changes: from the lowest content to the highest content): N (11.3), P (48.1), K (24.8), Ca (75.4), Mg (57.5), Fe (59.2), Zn (65.4) and Cu (43.7).

The aim of this study was to evaluate the effect of the foliar fertilizer InCa on the chemical composition of fruits and leaves of sweet cherry cultivar ‘Burlat’. The study involved 14-year old sweet cherry trees of ‘Burlat’ cultivar, grafted onto ‘PHL-A’ rootstock and growing at 4×3 m spacing. The trees were sprayed with InCa calcium fertilizer based on CaT technology (manufacturer: Plant Impact). The fertilizer was applied three times, at a dose of 1.5 dm3ha. The first foliar fertilization was performed at the beginning of the flowering period, and the next two took place at fourteen-day intervals. The fruits were analysed for nitrate content, and both fruits and leaves were considered for dry weight and macro- and micronutrient analysis. The use of InCa fertilizer improved the dry matter and calcium content and reduced potassium, magnesium and cadmium level in the leaves and fruits of sweet cherry. The fertilizer facilitated narrowing K:Ca and K:(Ca + Mg) ratioes and extending of K:Mg, and especially Ca:Mg ratio in both leaves and fruits. Foliar supplementation with the investigated preparation resulted in an increase in nitrogen and manganese content, and a drop in phosphorus, copper, nickel and lead concentration in the leaves of the studied sweet cherry cultivar.

Reactive materials represent a promising agent for environmental co-remediation. The research was aimed to determine the influence of hexavalent chromium in doses of 0, 25, 50, and 150 mg Cr(VI).kg-1 of soil as well as zero valent-iron, and lignite additives on the content of macroelements in the Indian mustard (Brassica juncea L.). The average accumulation of the analysed elements in Indian mustard grown in Cr(VI) contaminated soil were found to follow the decreasing order Mg>Na>P>Ca>K. Soil contamination at 150 mg Cr(VI).kg-1 of soil led to the highest increase in magnesium, calcium, sodium, and potassium content in Indian mustard. The application of zero-valent iron had a positive influence on the average Na and K content of the tested plant. The application of lignite had a positive influence on the average magnesium, sodium and calcium content in the above-ground parts of the studied plant. In the non-amended treatments (without reactive materials), the increasing rates of chromium (VI) had an explicitly positive effect on the content of phosphorous and sodium in Indian mustard.

The study was conducted in the buffer zone of the Kampinos National Park 30 km north from Warsaw in the growing seasons (April-October) of 1997-1999. In addition to element input into common rain collectors, their aerosol-gaseous input was determined, using collectors with artificial leaves of known surface areas - 2, 6 and 12 m^2 n^-2. It was found that the input of the majority of elements markedly increased with increasing artificial leaf area (Na'+, N-NH4'+, Mg'2+, Cl'-, N-NO3'-, S-SO4^2-, P-PO4^3-, and less intensively Cd'2+ and Cu'2+). This was not the case of H'+, Zn'2+, Pb'2+, and atmospheric input of water. Proportional increase in anions and cations neutralising them accompanied increasing artificial leaf area, so that water acidity was stable. As a result of parallel increases in the input of most elements with increasing leaf area proportions between elements were maintained at fairly the same level in leaf area gradient.

Aerosol samples were collected in May 1997 at a routine off-shore measurement station in the Gdansk Deep region and at Hel, the latter being a coastal station situated at the tip of the Hel Peninsula. Concentrations of NO3–, Cl–, Na+, Mg2+, K+ and Ca2+ were measured simultaneously at both stations. The sea influences the chemical composition of aerosols in the coastal zone of the Gulf of Gdansk regardless of season, time of day or direction of advection. Sodium chloride was always present in aerosols in the form of large particles originating from seawater. Besides the marine chloride and nitrate, additional amounts of these ions could have been of terrigenous origin. Sodium and chloride concentrations were dominant in the total mass of aerosols at both stations; however, these concentrations were three times higher at the marine station. Similarly, the concentrations of ions originating from seawater, like magnesium and calcium, were, on average, three times higher at the marine station. The chemical composition of aerosols and air over the Gulf of Gdansk was modified through the evaporation of chloride from the marine salt particles in reactions with gaseous nitric and sulphuric acids. A certain deficit of chloride versus sodium ions was noted. At the marine station the Cl–/Na+ ratio reached 0.89 š 0.2, on average, while over the land station it was 0.93 š 0.25, i.e. lower than the seawater standard.

The annual cycle of atmospheric nitrogen species and macroelements (Na+, K+, Ca2+, Mg2+ and Cl–) over the south-eastern Baltic region was investigated. A one-year record enabled the variability of nitrogen species and macroelements in the aerosol over the coastal station at Hel to be traced. The highest concentrations of sea salt components were recorded in summer, while anthropogenic nitrate concentrations were highest in winter. When the air masses were of mixed marine and continental origin, the nitric acid reacted with coarse sea salt particles to form stable, coarse sodium nitrate. This seems to be a permanent removal pathway for nitrate. Anthropogenic aerosol species like NH4+ or NO3– formed by gas-to-particle conversion were generally associated with fine particles (<1 žm). Coarse particles like sodium or chloride resulted from resuspension from seawater.

The objective of our study was to assess the residual effect of sewage sludge on the growth and yield of Prairie cordgrass and the content of crude ash, macroelements and heavy metals in the plant biomass. Field trials conducted in the years 2011 to 2013 focused on the assessment of the impact of municipal sewage sludge applied from 2008 to 2010on the growth and yield of Prairie cordgrass. The experiments followed the split-plot design with two variables: the rate of sewage sludge (DM-dry matter) at 0, 1.4, 2.8 and 4.2 t ha-1, corresponding to nitrogen fertilization with: 0, 50, 100, 150 kg ha-1, and the harvest time - fall and winter. The total dose of sewage sludge applied in 2008−2010 was 0, 4.2, 8.4 and 12.6 t DM ha-1, which corresponded to the total dose of nitrogen fertilization: 0, 150, 300 and 450 kg ha-1, respectively. The municipal sewage sludge at a rate of 8.4 t DM ha-1, compared to the Control, significantly increased the number of leaves per plant, the leaf and culm matter, the number of shoots per 1 m2, the dry matter yield, crude ash deposition and uptake of macroelements and heavy metals.

The study shows the content of macro- and microelements in the leaves and rhizomes of Glyceria maxima of the Słupia River in Słupsk. The content of macro and micro-elements in G. maxima was analyzed for each component separately and in an integrated way, and comparing the demand for nutritions. The largest quantity of nitrogen, phosphorus, potassium, magnesium and calcium were found in the leaves, meanwhile zinc, iron, manganese, nickel and copper in the G. maxima rhizomes. The amount of Zn and Cu, in all of the tested positions, within the range of the limit for the plants, and the concentrations of Ni and Mn exceed physiological needs. The U Mann Whitney test showed a number of statistically significant differences in the concentration of the analyzed elements in leaves – rhizomes, leaves – bottom sediment and rhizome bottom sediment relation. The relations between designated heavy metals formed a following series: Mn>Fe>Zn>Ni>Cu in leaves and Fe>Mn>Zn>Ni>Cu in rhizomes. The G. maxima shoots accumulated 985.8 do 1441.4 mmolc∙kg-1 in all the analyzed components, and the lower value of the sum of the accumulated macro and microelements were found in rhizomes. The sum of ion comospition of the macronutrients in the leaves and rhizomes was similar. The content of nitrogen was 51.7–53.7% of this amount, 5.8–8.6% phosphorus, potassium 22.8 – 26.6%, 4.9-5.8% of magnesium, calcium, 8.2–11.9%, and trace elements were 0.58% in total, in the case of leaves and 8.70% in the rhizomes.

The agricultural landscape of Western Pomerania is characterised by frequent occurrence of small, post-glacial water ponds commonly called mid-field ponds. They serve numerous important functions, both with regard to agriculture and ecology. Due to their specific location in the agricultural landscape, they are exposed to permanent and strong anthropic pressure, which often translates into pollution of surface water and benthic sediments with macro-and microelements. This study attempts to assess and determine the level of macro – and microelements in benthic sediments, depending on the type of agricultural production, on the example of selected mid-field ponds. The assessed benthic sediments of both ponds were characterised by varied macro - and microelement levels, depending on the collection site and the depth of their deposition. Based on the performed chemical analyses it was found that both observation points in the pond Żelisławiec were characterised by the highest concentrations occurring in the top layer (0-5 cm), which is related to the fact that there are areas of agriculture in the pond basin with the use of mineral and organic fertilisation and occurrence of higher water erosion. And the other assessed mid-field pond (Stare Czarnowo) showed the highest concentration of microelements in the middle layer, 5-15 cm. Statistical analyses revealed that statistically significant differences were observed only for potassium levels, depending on the type of agricultural production in the basin of both assessed ponds. This may result from various types of agricultural crops (Brassica napus L. var. napus and ×Triticosecale Wittm. ex A.Camus) and intense fertilization of arable land in Stare Czarnowo. Statistically significant differences in particular layers of sediment confirm that depending on the type of agricultural activity, mid-field ponds are supplied with various mineral matter at different times, resulting in its accumulation in benthic sediments.

Municipal sewage sludge contains many valuable nutrients which can be used in the cultivation of energy crops. Application of large doses of sewage sludge can be a cause of environmental pollution, especially with nutrients. The multiflora rose and the Virginia fanpetals are plants with high nutritional requirements. The use of municipal sewage sludge in the cultivation of energy crops will allow recycling the nutrients from this organic waste. The aim of the study was to evaluate the use of macroelements from municipal sewage sludge by the multiflora rose var. "Jatar" (Rosa multiflora Thunb. ex Murray) and the Virginia fanpetals (Sida hermaphrodita Rusby). Four levels of sewage sludge fertilization were applied in the 6-year field experiment: 0, 10, 20, 40, 60 Mg DM sludge ∙ ha-1. Sewage sludge was applied once before planting energy crops. Due to the low potassium content in sewage sludge, a single supplementary fertilization with 100 kg K ∙ ha-1 in the form of 40% potassium salt (KCl) was applied on each plot. The study involved the evaluation of the yield, uptake and use by energy plants of N, P, K, Ca, Mg, and Na from sewage sludge. It was found that the increasing doses of sewage sludge significantly raised the multiflora rose and the Virginia fanpetals biomass yields. The yield of the Virginia fanpetals was one and a half times higher than that of the multiflora rose. The increasing doses of sewage sludge significantly raised the contents and uptake of N, P, K, Ca, Mg, and Na by these plants. The highest uptake of macronutrients by the multiflora rose and the Virginia fanpetals crops was determined for 60 Mg DM ∙ ha-1 fertilization dose. The results show that the Virginia fanpetals used N, P, K, Ca, Mg, and Na from the sewage sludge to a greater extent than the multiflora rose. The analyses indicate that due to the greater yields, bioaccumulation and uptake of macronutrients, Virginia fanpetals is more effective in the ‘purification’ of the substrate from excess nutrients that may pose a threat to the environment.

Trees shed leaf litters throughout the year with varying intensity. In urban areas, due to the regular pruning of tree branches, the leaves which are used as a compost component have dominant share in the litterfall. The amount of nutrients released during composting depends on the abundance of the shed leaves. The research aimed to analyse and determine which of the deciduous tree species provide the highest amount of macronutrients and whether or not the heavy metals contained in them exceed the toxic level. It was found that the leaves of Alnus glutinosa (C/N = 20.57), Tilia cordata (33.31) and Fraxinus excelsior (33.88), which are the source of the highest amounts of nitrogen among the examined deciduous tree species, decompose at the fastest pace in the composting process. The process of decomposition of Quercus rubra (C/N = 64.30), Aesculus hippocastanum (58.16) and Fagus sylvatica (58.06) leaves, which are poorer in nitrogen compounds, takes much longer and is more difficult. It has also been shown that the heavy metals (Zn, Cu, Pb) contained in leaf litters do not pose any threat to the environment, as they do not exceed the permissible level of contamination.

The paper presents findings showing the influence of amending soil with biochar and biomass ash on the germination rate of Virginia mallow. Comparative analyses examined the relationship between the applied dosage of the natural fertilizers and the effectiveness of seed germination as well as mass of the plants at the initial stage of growth. The obtained plant material was also examined for the contents of selected macro-elements (phosphorus, potassium and calcium). The study shows that biochar applied as a fertilizer, at specific dosage, may enhance germination rate of Virginia mallow seeds. Addition of biomass ash into the soil, at certain doses, significantly impacts the growth of mass in Virginia fanpetals at the initial stage of development. It has been determined that addition of biochar, or biomass ash or their mixtures into the soil alters the concentration of phosphorus, potassium and calcium in above-ground parts of the plants.

The study was conducted in the region of Pomerania in North Poland (Człuchów Forest) 85 km south-east from the coast of the Baltic Sea, in the growing season (April-October) 2001-2002. Using collectors with artificial leaves of known surface areas (2,4 and 6 m2 m-2) the aerosol-gaseous input into standard rain collectors. It was found that input of Ca2+ was the highest (mean 772 g ha-1 month-1), followed by N-NH4+, S-SO42-, Cl-, N-NO3-, Na+, K+, Mg2+ and P-PO43-, while the input of H+ was the lowest (mean 5g ha-1 month-1). The input of great majority of elements clearly increased with surface area of the artificial leaves (Na+, N-NH4+, K+, Mg2+, Cl-, N-NO3-, S-SO42). In genera, with the increase of artificial leaves area from 0 to 10 m2 m-2 (Q10 index), the rise of input varied from 1,72 (S-SO42-) to 2,26 (Cl-). The process did not take places only for Ca2+, P-PO43-,H+, atmospheric water, and dust. These tendencies occurred in both two years of studies, and the differences of the results were small. Atmospheric input of elements in the Człuchów Forest was relatively small comparing to other parts of Poland. As far as the aerosol-gaseous fraction of input was concerned, the greatest role had the elements related to aerosol of seawater origins, like chlorine, sodium and magnesium.

The study of bottom sediments and organs of Sparganium erectum carried out in the summer of 2014 in the city of Lębork, located in Northern Poland. The aim of this study was to evaluate the content of macroelements and heavy metals in the leaves, rhizomes and roots S. erectum and in bottom sediments of the Łeba River as well as comparison of accumulation and translocation factors of N, P, K, Mg, Ca, Zn, Ni, Cu, Mn, Fe, Cd and Cr in researched organs of aquatic plant. The use of S. erectum for biomonitoring and phytoremediation has also been considered. The results of Mann Whitney U test showed a number of statistically significant differences in the content of chemical elements in the leaves, rhizomes, roots and in bottom sediments. The macroelements are mainly accumulated in leaves and heavy metals are accumulated in roots and rhizomes of S. erectum. Increased Mn and Fe content in roots and rhizomes of S. erectum, in relation this physiological needs, refers to the beneficial effects of this species in the water treatment and sludge from the bottom sediment of manganese and iron compounds. The obtained bioconcentration and translocation factors values allowed to state that S. erectum can be used for phytoremediation of contaminated bottom sediments because retains metals in their roots and limit Mn and Fe mobility from roots and rhizomes to leaves once absorbed by roots of plant.

The aim of the study was to determine the effect of soil contamination with cadmium on the content of selected elements (K, Ca, Mg, Na, Fe, Zn, Mo and Cu) and average ion equivalent proportions between K, Ca, Mg and Na in spring wheat. The application of a cadmium dose (2.8-560 mg Cd . kg-I of soil), resulted in a decrease in the amount of nearly all chemical elements. A slight increase in the content of calcium was noticed in wheat after the application of the lowest concentrations in the combination with and without NPK fertilization. A twofold decrease in the content of calcium was recorded only at the highest concentration of Cd as compared with the control. The addition of cadmium salt to the soil caused a broadening of the ratio K: (Ca + Mg), Ca : Mg, K : Mg and a narrowing of the ratio K : Na and K : Cs. The ion proportions did not exceed values regarded as appropriate for a good quality of fodder.

Zastosowane dawki kadmu (2:8-560 mg Cd . kg-1 gleby) spowodowały zmniejszenie ilości prawie wszystkich pierwiastków. Stwierdzono nieznaczny wzrost zawartości wapnia w pszenicy po zastosowaniu najmniejszych stężeń w kombinacji bez nawożenia i z nawożeniem NPK. 2-krotny spadek zawartości wapnia odnotowano dopiero przy najwyższym stężeniu Cd w porównaniu z kontrolą. Dodatek do gleby soli kadmu spowodował rozszerzenie stosunku K : (Ca + Mg), Ca: Mg i K : Mg oraz zawężenie stosunku K : Na i K : Ca. Proporcje jonowe nie przekraczały wartości uznanych za poprawne dla dobrej jakości paszy.

The main factor affecting the value and usefulness of soil is its richness in nutrients. Nutrient abundance is assessed from the content of available phosphorus, potassium and magnesium in the soil, taking into account the soil acidity. Chemical analyses of peat soils were carried out in 2012 in Lublin. Four soil samples were taken from each of the six soil excavations made in drained peatlands in the Tyśmienica River catchment area, Zaklęsłość Sosnowicka region. The analysed muck-peat soil samples had very acidic and acidic pH < 5.5. In majority of soil profiles the content of phosphorus, potassium and iron in the 5–10 cm soil layer was two times higher than in the deeper layers. Smallest amounts of these elements were found in the layer 35–40 cm. The analysed samples of organic soils had low or medium total nitrogen content ranging from 2 to 3%. Ash content was 15–17% in peat layer, above 25% in muck layer and over 40% in alluvial horizons.

The aim of the present study was to determine: the impact of electric current density on the quantity and quality of sewage sludge produced in anaerobic sequencing bio-electrochemical reactor (AnSBBER) with an iron electrode during the treatment of drainage from soilless cultivation of tomatoes. Direct electric current (DC) effect was determined at its following densities (J): 0.63 A/m2 (R1), 1.25 A/m2 (R2), 2.5 A/m2 (R3), and 5 A/m2 (R4). Sodium acetate in (C:N) ratio of 1.0 was supplied to the reactors to ensure the proper biofilm development. Contents of elements (K, P, S, Na, Al, Cu, Fe, Mn, Mo, Zn, Mg, C, N and Ca) in the biofilm were determined. Additionally, the content of total suspended solids and the percentage share of volatile suspensions (VSS) in the sludge were determined. The study showed that the organic matter content in the sludge corresponded to the values typical of the stabilized sludge (up to 28.8% d.m. in R2).The increase in electric current density caused an increase in the concentration of phosphorus in the formed sludge (from 6.34 to 8.00% d.m. in 0.63 and 5.00 A/m2, respectively). The analyzed sludge, compared to municipal sludge from wastewater treatment plants with biological reactors and activated sludge chambers, is richer in such elements as phosphorus, nitrogen, calcium, magnesium, potassium, sodium, and iron.

The objective of this research was to examine the concentrations of crude protein, P, K, Mg, Fe, Mn and Zn of 5 triticale genotypes and 2 barley cultivars (two-row) at different growth stages. The experiments were carried out at Süleyman Demirel University farm in Isparta during the growing season of 2012-2013. Three hexaploid triticale lines (SDÜ- 21, SDÜ-27, SDÜ-43) and 2 cultivars (Karma-2000 and Tatlıcak-97), and two-row barley cultivars (Hamidiye and Cumhuriyet) were used in the experiment. The experimental design was a randomized split block design with three replication. The genotypes were used as main plots and growth stage were used as sub-plots. The basic pre-sowing fertilization rates for all plots were 30 kg N·ha-1 and 50 kg P·ha-1, the rest of 30 kg N·ha-1 was applied at the early spring (stem-elongation stage). Plants were harvested at four stages, stem elongation, milk development, dough development and mature stage. Samples taken from each plot were dried to constant weight at 65°C in oven. After cooling, the samples were milled for crude protein and mineral element analyses. According to the results of variance analysis, the nutrient concentrations of triticale and barley genotypes showed variations depending on the genotypes and different growth stages. The crude protein content of barley cultivars were higher than triticale genotypes. The concentration of K, Fe, Mn and Zn in whole plants decreased from stem elongation to maturity, while Mg and P contents increased. Crude protein rate (18.59%) at dough development stage was higher than other growth stages. The nitrogen use efficiency of SDÜ-27 line, which can be used for cultivar registration, was higher than control cultivar (Karma - 2000; Tatlıcak-1997).

Podłoże po uprawie pieczarek (świeże, ang. spent mushroom substrate – SMS; kompostowane, ang. spent mushroom compost – SMC) stanowi odpadowy materiał organiczny z pieczarkarni. Zaliczono je do grupy odpadów z rolnictwa i innych jako „inny niewymieniony odpad”. Przy produkcji podłoża do uprawy tego grzyba wykorzystuje się, a jednocześnie utylizuje, odpady organiczne pochodzące z produkcji rolnej (dobrej jakości, o dużej zawartości węgla twardą słomę żytnią, pszenną, pszenżytnią, pomiot drobiowy – od brojlerów, kur niosek i indyków) oraz odpady mineralne z przemysłu (gips odpadowy z elektrofiltrów, fosfogips, CaCO3).

The chemical composition of spent mushroom substrate after cultivation of Agaricus bisporus from a modern, high performance mushroom hall in Siedlce region were determined. The substrate for cultivated mushrooms (ground + cover) came from different manufacturers. The dry matter content of the analysed spent mushroom substrate was average 36,5%, the reaction was mostly slightly acid or neutral (pH ranged 6,13-6,70), and content of the mineral nitrogen forms (N-NH4 i N-NOx) accounted for 1,24% of the total nitrogen, but it was several times more the ammonium nitrogen form. The total content of macroelements (N, Ca, P, Mg, Na) and same microelements (Co, B, Cu, Zn) was more then in the manure, with the most varied of the calcium content. The values of C:N ratio (average 12,3) was similar to the optimum levels in humus horizons of arable soils. The values of N:P:K ratio (2,6:1:1,8) indicated on deficiency of phosphorus and potassium. The content of heavy metals included in range allowing this waste material to fertilizer.
