Opis:
The three-factorial vegetative-pot experiment was carried out in 2007-2008. The first factor consisted of the series with and without compost of municipal sewage sludge and the second factor involved doses of multi-component mineral fertilizers. Perennial ryegrass (Lolium perenne) of Stadion cv. was the test plant. The purpose of the work was to determine the effect of mineral multi-component fertilizers with combined organic fertilization on the content total and forms assimilable of macroelements in soil. Single doses of mineral fertilizers and urea increased the content of nitrogen, phosphorus and potassium in the soil compared to the control. Doubling the doses of fertilizers and urea raised the content of nitrogen, phosphorus and potassium in the soil as compared to single doses. Types of multicomponent mineral fertilizers with the addition of urea did not have a major impact on the diversity of studied elements content in the soil. After two years of experiment, the soil to which compost was introduced in spring contained more nitrogen and phosphorus compared to the control object by 21% and 8.96% respectively. The potassium content in the soil was the same as in the control object. Doubling the doses of mineral fertilizers and urea with the participation of compost resulted in an increase in the content of available forms of phosphorus, potassium, magnesium and sulfate in the soil by 2.52%, 9.12%, 2.25% and 0.80%, respectively, in comparison with single doses. The content of available forms of phosphorus and potassium in the soil after the end of the experiment was greater than of the available forms of magnesium and sulfur.

Opis:
The aim of this study was to determine the effect of various methods of introducing manure in to the soil on the chem- ical properties of the soil. The field experiment was carried out in the Podlasie voivodship on a sandy soil. Cattle manure was ap- plied in a dose of 30 Mg ha-1 and mixed with the soil using a disc harrow or plowed into the depth of 10 and 20 cm. In soil samples, the content of available forms of phosphorus, potassium, mag- nesium, copper, sulfur, boron, manganese, zinc, iron and the soil reaction was determined. The results confirmed the influence of depth of manure application on soil properties. As the cultivation depth increased, the content of phosphorus and organic carbon in soil increased, C/N ratio expanded, but the content of magnesium and potassium in soil decreased. No effect of the cultivation depth on the soil pH value and the content of nitrogen, boron, zinc and sulfur was found. The results of the study indicate a different rate of manure changes in soil and the related need to develop ferti- lizer equivalents depending on the manure application method.

Opis:
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.

Opis:
Fish meat is a valuable dietary component owing its exceptionally high nutritional value, as it contains high quality protein, fat (including n-3 acids) and a variety of vitamins and minerals. The aim of this study was to determine the content of ash and minerals (macro- and microelements) in three freshwater fish species, and quantitative changes in smoked and marinated products. The research material originated from three species, i.e. common carp (Cyprinus carpio), rainbow trout (Oncorhynchus mykkis) and northern pike (Esox lucius). The following parameters were determined in samples of raw as well as processed fish meat: ash (using the gravimetric method, according to PN-ISO 936:2000) and the minerals Na, K, Ca, Mg, P, Fe, Zn, Mn, Cu (using inductively coupled plasma optical emission spectrometry ICP-OES). The statistical analysis of the results did not show significant differences in the ash content in meat of the three fish species. The ash content in processed fish meat differed significantly from that in raw fish, thus indicating changes in concentrations of the minerals. The differences depended on the applied processing technology. As for the mineral content, the examined fish species achieved high nutritional quality, with the highest content of magnesium, iron and zinc in common carp, potassium and phosphorus in rainbow trout and calcium in pike. The levels of the minerals in processed fish meat differed significantly from those in the raw material, especially in carp products (higher amounts of almost all the determined elements). Smoking as well as marinating resulted in a considerable increase in the sodium contet, and the highest values were obtained for marinated rainbow trout. Monitoring the content of macro- and microelements in fish meat is important for the consumer.

Opis:
The total content and relationships between macroelements (Ca, Mg, K, Na, Mn, Fe and Al) and soil properties along the soil catena in the hilly valley of Lier River, S Norway, are discussed in the paper. The upper and middle part of the Lier River valley is covered with Stagnic Phaeozems formed from silt loam and sandy loam. In some parts of middle slope, Haplic Phaeozems (Anocolluvic) formed from silt loam and sandy loam occurred. The flat areas in the lower part of slope were covered with Mollic Gleysols formed from silt and silt loam. The average total amounts of macroelements were not high: Ca – 4.04g kg -1, Mg – 4.34g kg -1, K – 4.31 g kg -1, Na – 0.53 g kg -1, Fe – 19.05 g kg -1, Mn – 0.32 g kg -1 and Al – 20.22 g kg -1. These total amounts showed little vertical and horizontal variance in the soil profiles. The principal component analysis showed that the total amounts of elements in analysed soils was dependent mainly on sand and silt, and the similarity of soil horizons, in the cluster analysis, proves the translocation of macroelements was probable.

Opis:
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.

Opis:
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.

Opis:
This paper presents the results obtained during reclamation of hard coal ash. The model was developed by covering the layer of ash with layers containing ash, organic by-products and mineral fertilizers in 10 different combinations. The experiment on reclamation of hard coal ash was conducted in 2003 on the premises of Dolna Odra Power Station in Poland. The physicochemical parameters of top layers were well suited for cultivation on the reclaimed land. Particularly favourable was the introduction of fermented municipal sewage sludge to top layers. In this way, the appropriate structure of the analysed top layers was obtained, as manifested by good abundance of forms of magnesium, potassium and phosphorus available for vegetation. The obtained results demonstrate the process of accumulation of the available forms of magnesium, potassium and phosphorus in underlays when the fertile surface layer is supplemented with fermented municipal sewage sludge. The results obtained in the experiment indicate, that hard coal ashes can be managed in this way. Due to the long-term character of physicochemical and chemical properties of both top layers and underlays, the results presented here justify the continuation of the conducted reclamation experiment.

Opis:
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).

Opis:
Dry matter, crude protein, crude fat, crude ash, crude fibre and elements (phosphorus, potassium, sodium, calcium, magnesium, zinc, iron, manganese, lead, chromium, molybdenum, cadmium, cobalt, nickel and copper) were determined in extracted and unextracted Moringa oleifera leaves. The leaves were ground in a laboratory grinder (unextracted leaves) and a portion was subjected to continuous comprehensive water extraction at 95-100°C (extracted leaves). Next, densification was carried out in a rotary evaporator, where the material was dried natively in vacuum. The chemical content of the samples was analysed according to standard methods. The concentration of P was determined by the colorimetric method. An Atomic Absorption Spectrometer was used to determine K, Na and Ca by emission flame spectroscopy, and Mg, Zn, Fe, Mn, Pb, Cr, Mo, Cd, Co, Ni and Cu by absorption flame spectroscopy. The nutritional value of herbs depends on the chemical composition of dry mass, especially the content of crude protein, mineral components and fibre fractions. The crude protein content of the extracted and unextracted leaves was 13.6 and 31.6% dry matter (d. m.), respectively. No crude fibre was found in the moringa leaf extract. Dried leaves contained 8% d. m. of crude fibre. Concentrations of crude fat in unextracted leaves implicated that they had five-fold more lipids than extracted from leaves. Total carbohydrates appeared to be the main component of dry mass. More total carbohydrates were found in the extract than in dried leaves (71 and 50% d. m., respectively). The research showed significant differences in the content of macronutrients between extracted and unextracted leaves of moringa. The extracted leaves contained higher quantities of all the studied macroelements. Moringa oleifera leaves may be considered to be a good and safe source of Fe, Zn and Cu. No Ni or Cd was found in the leaves of moringa.
