Opis:
The degree of complexation of microelement ions by the biodegradable chelating agent - IDHA was examined in the work. The tests were carried out in water and in a simulated fertilizer environment. In order to compare the obtained results, tests were also carried out for the commonly used EDTA. The performed analyzes allow to determine the influence of the presence of compounds containing macroelements on the degree of binding of microelement ions by the biodegradable IDHA and EDTA chelators. The obtained results make it possible to determine the optimal conditions for the chelation of cations by IDHA, which in the future may be used in the production of micronutrient fertilizers on a large scale.

Opis:
Ziarno pszenżyta charakteryzuje się wysoką wartością paszową, ale stwarza również możliwości wykorzystania go w celach konsumpcyjnych, gdzie może być wykorzystywane jako surowiec do produkcji chleba. Wartość wypiekowa związana jest z parametrami technologicznymi, które powinny cechować się optymalnymi wartościami. Są one determinowane, m. in., nawożeniem mineralnym, jak i naturalnym. W związku z powyższym przeprowadzono 2. czynnikowe badania, założone metodą losowanych podbloków. Materiał doświadczalny stanowiło ziarno pszenżyta ozimego. Czynnikami badawczymi były: nawożenie naturalne (obornik) i aplikacja mikroelementami (Cu, Zn, Mn, Cu+Zn+Mn). Celem było sprawdzenie wpływu wyżej wymienionych czynników oraz ich interakcji na wartość technologiczną ziarna. Najwyższą wartość liczby opadania, w stosunku do obiektu kontrolnego, stwierdzono po zastosowaniu 30 t⸱ha-1 obornika oraz na obiekcie, gdzie aplikowano dolistnie łącznie miedź, cynk i mangan. Stwierdzono również, że nawożenie obornikiem i dolistne nawożenie Cu, Zn, Mn oraz łączne ich zastosowanie powodowało średnio istotny wzrost wartości cech kompleksu białkowego ziarna pszenżyta (białko, gluten, sedymentacja) i objętości pieczywa, w stosunku do kontroli. Wskaźniki kompleksu enzymatycznego i białkowego były istotnie determinowane współdziałaniem nawożenia naturalnego i aplikacją mikroelementami. Najkorzystniejsze wartości tych cech stwierdzono po zastosowaniu obornika oraz dolistnie cynku.
Triticale grain has a high feed value, but it can also be used for consumption purposes, where it can be used as a raw material for the production of bread. The baking value is related to the technological parameters, which should be characterized by optimal values. They are determined, among other things, by both mineral and natural fertilisation. Therefore, two-factor research was carried out using the randomized subblock method. The experimental material consisted of winter triticale grain. The research factors were: natural fertilisation (manure) and foliar spraying with selected microelements (Cu, Zn, Mn, Cu+Zn+Mn). The aim was to check the influence of the abovementioned factors and their interactions on the technological value of grain. The highest values of the falling number, in relation to the control objects, were found after the application of manure and in the object where a total of copper, zinc and manganese were applied foliarly. It was found that manure fertilisation and foliar fertilisation with copper, zinc, manganese and their combined application resulted in an average in the value increase of features of the protein complex of triticale (protein, gluten, sedimentation) and bread volume, compared to the control. The indicators of the enzymatic and protein complex were significantly determined by the interaction of natural fertilisation and the application of microelements. The most favorable values of these features were found after the application of manure and foliar zinc.

Opis:
The research was carried out in the morainic areas and in river valleys in NE Poland, where seven sites located in the macroregion of Masurian Lakeland were selected. Thirteen soil profiles representing the following organic soils were studied: earth-covered murshic soils (OMnm), murshic peat soils (OTmu), hemic murshic soils (OMhe) and sapric murshic soils (OMsa). The aim of the research was to investigate the content of selected macro- and microelements in surface formations of organic soils and to determine the influence of sedimentation processes on their spatial distribution. In terms of quantity, the analyzed macro- and microelements can be arranged as follows: Ca > Al > Fe > K > Mg > Na > P > Mn > Zn > Pb > Cr > Ni > Cu > Co. Organic soils situated in the depressions had various degrees of silting with mineral sediments from the nearby areas. Along with erosive waters, deluvial material rich in minerals was flowing along the morainic slopes. Therefore, mineral-organic formations (AO) located in the ecotone zone between mineral and organic soils had the highest content of total Mg – 4.85 g kg-1, K – 5.94 g kg-1, Al – 24.87 g kg-1, Fe – 17.77 g kg-1, Zn – 0.066 g kg-1, Cr – 0.046 g kg-1, Ni – 0.025 g kg-1, Pb – 0.060 g kg-1. The highest content of total calcium, manganese, iron, copper and cobalt was found in mineral-organic formations (AO) and strongly silted murshes (Mtsz). The contents of calcium and sodium were significantly positively and the contents of other macro- and microelements were significantly negatively correlated with the amount of organic matter, organic carbon and total nitrogen.

Opis:
The monitoring of metals and other chemical elements in the basic sources of diet, mainly for children, is very important for preventing health issues. The aim of this work was to determine the concentration of selected essential (Ca, K, Mg, Mo, Na, Zn) and non-mutagenic elements (Ag, Al, Ba, Li, Sb, Sr) in ewe milk from the Orava region in northern Slovakia. Twenty milk samples were analysed in June and August using an inductively-coupled plasma optical emission spectrometry. The differences in elements concentration between the seasonal periods were not significant (p < 0.05), except for lithium (p < 0.05). The essential elements concentration was within the recommended levels, while the non-mutagenic and potentially toxic metals consist was under the permissible limits. However, there were found very strong and significant relationships between the elements which may suggest the synergistic / additive or antagonistic effects of some elements.

Opis:
Celem trzyletniego doświadczenia polowego była ocena reakcji pszenicy ozimej, odmiany RGT Kilimanjaro na zróżnicowane nawożenie dolistne. Doświadczenie założono w układzie losowanych bloków na polach Podkarpackiego Ośrodka Doradztwa Rolniczego w Boguchwale. Badanym czynnikiem były zróżnicowane warianty nawożenia dolistnego: (B) – dwukrotny oprysk YaraVita Zboże oraz (C) – dwukrotny oprysk YaraVita Zboże, jednokrotny YaraVita Kombiphos i jednokrotny YaraVita Thiotrac, które porównano do kontroli (A). Wykazano, że zmienne warunki pogodowe w latach badań wpłynęły modyfikująco na uzyskane plony. W 2017 r. zebrano ponad 9 t⸱ha-1 ziarna, natomiast w latach 2018 i 2019 odpowiednio o 2,0 i 0,92 t⸱ha-1 mniej. Po zastosowaniu nawożenia dolistnego w wariancie C i B uzyskano istotnie wyższe plony w porównaniu do kontroli, odpowiednio o 0,72 t⸱ha-1 i 0,44 t⸱ha-1. Czterokrotne nawożenie dolistne (wariant C) wpłynęło na istotny wzrost MTZ oraz indeksów zieloności liści (SPAD) i powierzchni liści (LAI) w porównaniu do kontroli. W przypadku przewodności szparkowej liści (Gs) dowiedziono, że zastosowane nawożenie w wariancie C skutkowało zmniejszeniem odczytów w odniesieniu do kontroli. Użyte nawozy dolistne w wariancie C wpłynęły także na istotny wzrost zawartości w ziarnie białka ogólnego a spadek włókna w odniesieniu do kontroli. W przypadku wariantu B uzyskane różnice były nieistotne. W uprawie pszenicy ozimej należy zatem zalecać intensywniejszy wariant nawożenia dolistnego.
The aim of the three-year field experiment was to evaluate the reaction of winter wheat, RGT Kilimanjaro cultivar to different foliar fertilization. The experiment was set up in a randomized blocks in the fields of the Podkarpackie Agricultural Advisory Center in Boguchwała. The tested factor consisted of various variants of foliar fertilization: B – two-time spraying of YaraVita Grain and C – two-time spraying of YaraVita Grain, one-time YaraVita Kombiphos and one-time YaraVita Thiotrac, which were compared to the control (A). It was shown that the variable weather conditions in the years of the research had a modifying effect on the yields obtained. In 2017, more than 9 t⸱ha-1 grain was harvested, while in 2018 and 2019, by 2.0 and 0.92 t⸱ha-1 less, respectively. After applying foliar fertilization in variants C and B, the yields were significantly higher compared to the control, by 0.72 t⸱ha-1 and 0.44 t⸱ha-1, respectively. Four-fold foliar fertilization (variant C) significantly increased WTG and indices of Soil Plant Analysis System (SPAD) and leaf area index (LAI) compared to the control. In the case of the stomatal conductivity of leaves (Gs), it was proved that the applied fertilization in variant C resulted in a decrease in readings in relation to the control. The foliar fertilizers used in variant C significantly increased the content of total protein in the grain and the decrease in fiber compared to the control. In the case of variant B, the obtained differences were insignificant. Therefore, in the cultivation of winter wheat, a more intensive variant of foliar fertilization should be recommended.

Opis:
A tillage system can affect significantly the concentration of some heavy metals and their availability to plants which grow on the tilled soil. The purpose of this study has been to determine the impact of different tillage systems on the chemical properties of arable sandy loam soils under the same crop rotation, organic residue management and mineral fertilization. A single-treatment field experiment in a randomised block design was performed on sandy loam soils. Four-year tillage study data were compiled and compared with respect to full-inversion tillage (FIT), strip-till (ST) and reduced tillage (RT) systems. Soil samples were mineralised in a mixture of HF and HClO4 acids to determine the total content of metals. Total organic carbon (TOC) and total nitrogen (Nt) were also assayed. The content of available metal forms was determined using diethylene triamine pentaacetic acid (DTPA). The soil maintained in the FIT system contained significantly more Zn and Fe available to plants than the soil cultivated according to the RT and ST systems. The FIT and ST systems decreased the total Zn, Cu, Mn and Fe content in soil significantly compared with the RT system. Relative accumulation of the heavy metals at the depth of 30-50 cm can be related to the distribution of the clay fraction in soil profiles. In the topsoil (0-30 cm), the average content of TOC was significantly higher under the RT than under FIT and ST systems. The results confirm that a tillage system is one of the factors affecting the content of heavy metals, TOC accumulation and heavy metal distribution in sandy loam soils, although the pedogenic processes determining the quality of arable soils quality must be considered as well.

Various apple rootstock genotypes may affect fruit tree nutrition. The plant nutritional status has a significant impact on the growth and yield of apple trees. The experiment was conducted in 2007-2015, at the Experimental Station in Samotwór near Wrocław, south-western Poland. During the nine-year study, the impact of different rootstocks (M.26, B.7-35, B.396, ARM 18, M.9, B.491, P 16, B.146 and PB-4) on the nutritional status, growth and yield of ‘Mutsu’ apple trees was investigated. Samples of leaves were collected for the analysis of macro– and microelements in the second half of July in 2009-2011. The study showed an ambiguous influence of rootstock on leaf macro-and microelement composition. This effect differed depending on a year. The results of the average content of the analysed components showed no effect of a rootstock on P, Mg, Mn and Zn concentrations in the leaves. M.26 rootstock resulted in the lower copper level (a significant difference when compared to B.7-35, M.9, B.146 and B.491). Trees on B.491, M.26 and B.7-35 rootstocks were worse stocked in boron than apple trees on ARM-18, M.9 and B.396. In comparison with stronger growing rootstocks, trees on PB-4 were characterised by the low content of calcium. Trees on B.7-35 rootstock grew the most, while the ones grafted on PB-4 showed the weakest growth and had the smallest fruits. The highest number of root suckers was observed for trees grafted on B.7-35 and ARM 18. Until the ninth year after planting, the largest yield was obtained from trees on B.396. In the present study, this rootstock proved to be the best for the ‘Mutsu’ cultivar

The experiment involved two foliar preparations of biostimulating properties containing silicon and amino acids. The aim of the study was to asses a synergistic effect of foliar application of amino acids and silicon on the content of micro- and macroelements in phytomass of grassland. It was conducted in the years 2017-2019, at an Experimental Station in Prusy near Kraków belonging to the Department of Agroecology and Crop Production, University of Agriculture in Kraków. The field experiment in a randomized block design was repeated four times and the area of the experimental plots was 10 m2. The plots were covered with loess-based degraded chernozem of class I in the Polish soil classification system. The experimental variants involved separate treatments with either silicon preparation at a dose of 0.8 dm3 ha-1 or amino acid preparation at a dose of 2.0 dm3 ha-1, and both preparations together at the mentioned doses. Foliar fertilization with the amino acid preparation and combined fertilization with silicon and amino acids significantly (p≤0.05) increased the content of the investigated macroelements. The difference was the greatest in the first year of the study. For potassium it reached 19.5% in the plants from the first cut treated with a combination of silicon and amino acids. The combination enhanced also the content of zinc, copper, manganese and iron. In summary, joint application of silicon and amino acids positively influenced the concentration of minerals in phytomass of grassland. In such cases fertilization is necessary to improve mineral levels in phytomass of grassland.

Opis:
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.

Opis:
Age-related macular degeneration (AMD), glaucoma and cataracts are the most common eye diseases. They are predominantly caused by insufficient amounts of antioxidants in the body, which include lutein, zeaxanthin, lycopene, omega-3 fatty acids, vitamins and micronutrients. The positive properties of these biologically active substances affect the neutralization of reactive oxygen species, slow absorption of UV radiation, and improve blood supply to the structural elements of the eye. Deficiency of these substances has a negative effect on the functioning of the eye, leading to degeneration of its structures. Presently, a fully effective method of treatment has not been discovered, therefore preventative measures, especially those including a healthy diet and lifestyle, are highly important as the human body cannot synthesize these beneficial substances. This requires increasing public awareness concerning products with high nutritional value, which should be included in people's daily diet.

Opis:
Do badań wytypowano położoną w zlewni typowo rolniczej, rzekę Gowienicę Miedwiańską. Badania prowadzono w latach 2014 – 2015. Próbki osadów dennych z badanej rzeki pobierano z warstwy 0-30 cm. W pobranych próbkach oznaczono zawartość całkowitą pierwiastków tj.: Ca, Cu, Fe, K, Mg, Mn, Na, Zn. Celem podjętych badań był wstępny monitoring rozprzestrzeniania się makro- i mikroskładników w osadach dennych rzeki Gowienicy wzdłuż jej biegu. Wykonane analizy w próbkach osadów dennych pozwoliły zaobserwować, że najwyższe stężenia analizowanych pierwiastków, zarówno w 2014 i 2015 roku wystąpiły w końcowym odcinku badanej rzeki (P-5 i 6) za wyjątkiem stężeń cynku, gdzie najwyższe stężenie wystąpiło w początkowym jej odcinku w punkcie nr 2. Podwyższone stężenia spowodowane mogą być spowolnieniem biegu rzeki. Najwyższe istotnie statystycznie dodatnią korelacje dla osadów rzeki Gowienicy wykazano pomiędzy magnezem i sodem w 2014 i 2015 roku. Również analiza wykazała istotnie statystyczną korelacje dla wapnia i miedzi (w 2014 i 2015 roku) oraz dla wapnia i manganu w 2014 i 2015 roku.
Gowienica Miedwiańska river, located in a typical agricultural catchment, was selected for the research. They were carried out in 2014-2015. Samples of bottom sediments from the river were collected from the 0-30 cm layer. In the samples taken, the total content of the elements was determined: Ca, Cu, Fe, K, Mg, Mn, Na, Zn. The aim of the research was to initially monitor the spread of macro- and microelements in bottom sediments of the Gowienica River along its course. The analyzes performed in the bottom sediment samples allowed to observe that the highest concentrations of the analyzed elements in both 2014 and 2015 occurred in the final section of the studied river (P-5 and 6) with the exception of zinc concentrations, where the highest concentration occurred in the initial section in point no. 2. Increased concentrations may be caused by a slowing down of the river water speed. The highest statistically significant positive correlations for the deposits of the Gowienica River appeared between magnesium and sodium in 2014 and 2015. The analysis also showed statistically significant correlations for calcium and copper (in 2014 and 2015) and for calcium and manganese in 2014 and 2015.

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.

Opis:
In the years 2008-2011, an environmental study was conducted for Polish soils, focusing on the south-eastern Poland soils, as they exhibit significant acidification. This study aimed at assessing the current pHKCl and the supply of basic macro- (P, K, Mg and S-SO4) and microelements (B, Cu, Fe, Mn and Zn) in the collected soil samples, and also at determining their relationship with the soil agronomic category, humus content and pH class. Soil reaction and humus and macronutrient content were positively correlated with the amount of colloidal clay and particles < 0.02 mm. In the majority of cases, the macro-element content in the soil was positively correlated with soil pH and humus content. As for microelements, a usually significant and positive correlation was found between the soil agronomic category and the content of manganese, iron and zinc, whereas for the content of boron and copper, no such relationship was observed. A significant and positive correlation between soil reaction and the content of manganese, iron and boron was also found. Such correlations were not observed in relation to copper and zinc content. Statistical analysis indicated that the content of boron and manganese depended to the greatest extent on the investigated physicochemical properties.

Opis:
Although beneficial properties of mineral waters are acknowledged by law in many countries, the use of water for medicinal purposes is not universally accepted. Notably numerous waters (especially mineral and curative ones) have high concentrations of mineral and trace elements. These mineral waters are common on the market and their availability is not regulated by law. Due to the hazard of overdosing, quantification of trace elements and minerals seems to be necessary. The World Health Organization, European Standards and Polish Standards recommend different methods for elemental determination, i.e. spectrometry, photometry for zinc determination, colorimetry or spectrometry for copper, and ionic chromatography for calcium, chloride and fluoride. In this paper, alternative, electrochemical methods have been applied to determine zinc, copper, calcium, chloride and fluoride in most popular natural and curative waters from southern Poland. The determined elemental content varied between 3.85-33.54 μg L-1 for zinc, 85-15.33 μg L-1 for copper, 2.8-2433.63 mg L-1 for chloride, 0.4-1.66 mg L-1 for fluoride and 11.05-478.48 mg L-1 for calcium. The voltammetric method was tested according to the validation procedures, taking into account the following parametes: linearity range, limit of detection and limit of quantification and precision. The results show that the applied electroanalytical methods are suitable for determination of the selected elements in waters of natural origin, ensuring low instrumental and analysis costs while providing results comparable with ones achieved with recommended methods.
