Opis:
The effect of chemically (solid sodium humate) and mechanically (Lignofert) treated coal application as a soil remediate substance and NPK (artificial) fertilizers, on the content of heavy metals in root, straw and grain of spring barley and in the soil have been investigated on Haplic Luvisol in the pot trial realized in vegetative cage placed on the territory of Slovak Agricultural University in Nitra (48°18' N, 18°05' E). The achieved results did not confirm the proclaimed inhibitive effect of sodium humate (SH) and Lignofert (Lig) for entrance of heavy metals into the plants. Conversely, the content of three out of eleven metals (As, Cd, Ni) in the barley grain and one (Fe) in the straw increased after SH application in a statistically significant way in comparison with the control variant. A significant decrease was demonstrated only in the content of mercury in the grain. Lignofert statistically significantly increased the content of up to four metals (Cd, Hg, Cu and Co) in the grain and one of them (Hg) in the straw. Its application did not cause the significant decrease of any heavy metal contents in the grain. The content only of one metal (Zn) decreased in the straw significantly. The application of a rational dose of NPK fertilizers in a statistically significant way increased the content of eight out of eleven investigated heavy metals in the barley corn as a result of their moderate acidification effect on the soil. The use of SH and Lig was not more risky from the viewpoint of heavy metal cumulation in spring barley than the use of NPK. fertilizers. However, their application in order to inhibit the entrance of most heavy metals into the plants is not rational. At the same time both coal substances significantly simultaneously increased the content of carbon and pH value in the soil. The use of fertilizers caused a high decrease of carbon content in the soil but their effect on heavy metal level in the soil was positive, it was lower than the effect of coal substances. The overall quantities of metals in the soil of all variants were lower than allowable limit at the end of the trial.
Badano wpływ aplikacji chemicznie (humian sodu) i mechanicznie (Lignofert) modyfikowanego węgla wraz z nawozami sztucznymi na zawartość metali ciężkich w korzeniach, pędach oraz ziarnie jęczmienia. Badania prowadzono w glebie płowej z lessu w eksperymencie donicowym. Eksperyment przeprowadzono w Słowackim Uniwersytecie Rolniczym w Nitrze (48° 18' N, 18°06' E). Uzyskane wyniki nie potwierdziły zakładanego hamującego wpływu humianu sodu (SH) i Lignofert (Lig) na pobieranie metali ciężkich z gleby przez rośliny. Przeciwnie odnotowany został statystycznie istotny wzrost zawartości trzech (As, Cd, Ni) spośród 11 badanych metali w ziarnie jęczmienia oraz jednego (Fe) w pędach tej rośliny po dodaniu SH w porównaniu z kontrolą. Lignofert spowodował statystycznie istotny wzrost zawartości czterech metali (Cd, Hg, Cu i Co) w ziarnie oraz jednego (Hg) w pędach. Zawartość cynku w pędach zmniejszyła się w sposób statystycznie istotny. Zastosowanie nawozów sztucznych spowodowało wzrost zawartości 8 spośród 11 badanych metali w ziarnie jęczmienia. Było to związane z zakwaszeniem gleby przez stosowane nawozy. Użycie SH i Lig nie stanowiło większego zagrożenia w aspekcie kumulacji metali w młodych pędach roślin niż zastosowanie nawozów sztucznych. Jednakże stosowanie SH i Lig w celu ochrony roślin przed gromadzeniem metali ciężkich nie jest racjonalne. Obydwa stosowane związki węglowe powodowały wzrost pH i zawartości węgla w glebie. Aplikacja nawozów sztucznych była przyczyną silnego zmniejszenia zawartości węgla w glebie. Zawartość metali ciężkich w glebie we wszystkich przeprowadzonych próbach była mniejsza niż ustanowione limity.

Opis:
The influence of different tillage and fertilization practices on changes in soil pH and sorptive parameters of loamy haplic Luvisol was evaluated in a long-term field experiment (established in 1994, in the locality of Dolná Malanta, at the experimental station of the Slovak University of Agriculture in Nitra). The field experiment included two types of soil tillage (conventional tillage – CT and reduced tillage – RT) and also three treatments of fertilization (1. Co – control, 2. PR+NPK – crop residues together with added NPK fertilizers, and 3. NPK – with added NPK fertilizers). The soil was sampled from all treatment sites throughout 1994-2011. The results showed a statistically significant influence of tillage and fertilization on pH and sorptive complex of haplic Luvisol. The values of pH were higher (by 4%) in RT than in CT. The sum of basic cations (SBC), cation exchangeable capacity (CEC) and base saturation (BS) were all higher in RT, by 11%, 8% and 3% respectively, than in CT. In NPK (by 16%) and in PR+NPK (by 20%) the values of hydrolytic acidity (Ha) were decreased in comparison to the control. On the other hand, SBC was elevated. This led to the increase of CEC and BS. Conventional tillage and application of crop residues together with NPK fertilizers increased pH by 0.06 and 0.03 units per year, respectively, which means that the pH in the soil increased by14% and 8%, correspondingly, between 1994 and 2011. In CT and in PR+NPK, an increase of SBC occurred at an average rate of 3.17 and 1.93 mmol kg-1 year-1, respectively. A positive correlation between the content of soil organic carbon (TOC) and Ha (r = 0.334, P ≤ 0.01, n = 54), as well as a negative correlation between TOC and BS (r = -0.307, P ≤ 0.05, n = 54) were determined only in CT.

Opis:
The addition of organic material to the soil can be an effective alternative to the environmentally unsafe chemical treatments that are used to control plant parasitic nematodes. We evaluated the effects of vermicompost alone, and aqueous solutions of vermicompost (vermicompost tea) either alone or mixed with urea, on the development and survival of two potato-cyst nematodes: Globodera rostochiensis (pathotype Ro1) and G. pallida (pathotype Pa2) and on the growth parameters of the host potato plants. Soil amendments with these materials significantly decreased the number of cysts · 400 g–1 of both species in the soil, the number of eggs and juveniles · cyst–1 of both species, and the number of eggs and juveniles · g–1 of both species in the soil, relative to the untreated controls. The suppressive effect was significantly higher at the highest dose than the lowest treatment dose, for all tested materials. Globodera rostochiensis was more sensitive to all the tested materials than G. pallida. The aqueous solutions of vermicompost alone or in combination with urea were more effective than the solid vermicompost used alone, for controlling both species. Vermicompost and the vermicompost teas had positive effects on plant fresh stem weight and stem height. The application of vermicompost tea instead of the solid vermicompost, substantially decreased the amount of material needed. These amendments are thus promising for the control of potato-cyst nematodes in sustainable agricultural systems.

spring barley (Hordeum vulgare L.)
Opis:
The effect of two recycled waste rock wools (Nobasyp and Agrodrap) on the yield parameters of spring barley and some agrochemical soil parameters nas been studied in a pot trial conducted in a vegetation cage located at the SAU in Nitra (48°18' N, 18°05' E) on the Kaplic Luvisol (25 kg soil per pot). Achieved results have shown that the application of both kinds of rock wool had a positive but not statistically significant effect on the grain and straw yield of spring barley. The Nobasyp effect on the yield was more positive than the one of Agrodrap. Combined application of Nobasyp (20 Mg o ha^-1) and NPK fertilizers resulted in the highest grain and straw yields. On the other hand, combined application of Agrodrap and NPK fertilizers (under the use of both doses - 10 and 20 Mg o ha^-1) was not well-founded, because the yields achieved by interactive effect of NPK fertilizers and Agrodrap were lower than the ones achieved by solely use of NPK fertilizers. The rock wool + NPK fertilizers application inhibited the negative effect of nitrogen on increase of crude protein content and the decrease of starch in the barley grain. Both kinds of rock wool significantly increased the cation exchange capacity, madę the soil lighter, moderately increased pH of the soil and have had a positive effect on the total carbon content and the organie matter quality. The positive effect of Nobasyp on quantitative and qualitative parameters of spring barley and some soil parameters enables Nobasyp to be accepted not as a waste product but as a soil remediate substance, or an indirect fertilizer.
W doświadczeniu wazonowym, prowadzonym w hali wegetacyjnej Słowackiego Uniwersytetu Rolniczego w Nitrze (48° 18' N, 18°05' E), założonym na glebie płowej (25 kg gleby w wazonie) badano oddziaływanie dwóch odpadów wełny mineralnej (Nobasyp i Agrodrap) na parametry plonu jęczmienia jarego i niektóre agrochemiczne parametry gleby. Uzyskane wyniki wykazały, że stosowanie obydwóch rodzajów wełny mineralnej miało pozytywny, ale statycznie nieistotny wpływ na plon ziarna i słomy jęczmienia jarego. Wpływ Nobasypu na plon był bardziej widoczny niż ten wywołany przez Agrodrap. Łączne zastosowanie Nobasypu (20 Mg o ha^-1) oraz nawozów NPK skutkowało największymi plonami ziarna i sfomy. Z drugiej strony, łączne stosowanie Agdrapu oraz nawozów NPK (w obydwu zastosowanych dawkach - 10 i 20 Mg - ha^-1) nie było w pełni uzasadnione, ponieważ plony uzyskane w wyniku wzajemnego działania nawozów NPK i Agrodrapu były mniejsze niż te uzyskane po użyciu wyłącznie nawozów NPK. Stosowanie wełny mineralnej i nawozów NPK łagodziło ujemny wpływ azotu, który powodował wzrost zawartości białka surowego i obniżanie zawartość skrobi w ziarnie jęczmienia. Obydwa rodzaje wełny mineralnej znacząco zwiększały kationową pojemność wymienną, czyniły glebę bardziej pulchną, umiarkowanie podnosiły wartość pH gleby oraz miały pozytywny wpływ na ogólną zawartość węgla i jakość materii organicznej. Pozytywne oddziaływanie Nobasypu na ilościowe i jakościowe parametry jęczmienia jarego oraz niektóre parametry gleby umożliwia jego uznanie za substancję ulepszającą glebę lub nawóz pośredni, a nie jako produkt odpadowy.

Opis:
Mineral N fertilizer application may have an effect on soil organic matter and other soil parameters. Therefore, we studied the effects of different doses of N fertilization on soil organic matter and chemical properties of Haplic Luvisol in the locality of Dolná Malanta (Slovakia) during 2014–2016. Soil samples were collected from the plots exposed to the following treatments: 1. N0 – no N fertilization as control during 2014–2016, 2. N40 – N fertilizer at the rate of 40 kg N ha–1 in 2014 and 2016, 3. N80 – N fertilizer at the rate of 80 kg N ha–1 in 2014 and 2016, 4. N160 – N fertilizer at the rate of 160 kg N ha–1 in 2015, and 5. N240 – N fertilizer at the rate of 240 kg N ha–1 in 2015. The results showed that in N80 the soil organic carbon (SOC) content increased by 32% in comparison to N0. The addition of 80 kg ha-1 of N significantly decreased the humic substances (HS) content in the soil by 16% compared to N0. The higher doses of N fertilization 80 rather than 40 kg ha-1 as well as 240 rather than 160 kg ha-1 significantly decreased humus stability. The addition of N fertilization decreased the average values of soil pH. Values of hydrolytic acidity (Ha) increased by 41% and 46% in N40 and N80, respectively than N0, but on the other hand, this one decreased by 36% and 27% in N160 and N240, respectively in comparison to N0. Positive statistically significant correlations were determined between soil pH and SOC in N40 and N80 treatments. The increase of soil pH was connected with higher humus quality in N160 and N240. Negative correlations between humic acids (HA) and sum of basic cations (SBC) and cation exchange capacity (CEC) were observed in N80 < N160 < N240 treatments. Higher values of fulvic acids corresponded with lesser CEC in N80 and N160 treatments. In N160, with increased humus quality, CEC significantly decreased. The same effect was observed in N240. In addition, in N240, we also observed that with increased HA:FA ratio SBC and base saturation significantly decreased.

Opis:
The decrease in application of organic fertilizers into arable soils in Slovakia observed for the past twenty-five years has caused degradation of their physical, chemical and biological parameters. In order to solve this problem, Slovak farmers often add to soil such carbon-rich substances which either pose a risk of increasing the heavy metal content of soil, or whose purchase and use are economically demanding. Meanwhile, sawdust is a cheap and available carbon-rich material. Therefore, the objective of a two-year pot experiment was to determine the impact of sawdust used alone or with added inorganic nitrogen on the parameters of sugar beet yield as well as on some soil parameters. The results proved that the separate application of sawdust in autumn in doses of 3.4 t ha-1 and 6.8 t ha-1 caused the retardation of the growth of sugar beet and the decrease of the total chlorophyll content in leaves during the first 80 days of plant growth and development. This application did not have the significant impact on the root yield, but it increased the sugar content of sugar beet roots. The roots contained less a-amino nitrogen and more potassium. The number of nitrogen-fixing bacteria of genus Azotobacter chroococcum (AzCh) and the quantity of organic carbon in soil increased. The addition of mineral nitrogen fertilizer in a dose of 60 kg ha-1 into sawdust before sugar beet sowing in spring lowered or even eliminated the negative impact of sawdust itself on the beet growth and the content of total chlorophyll. It also increased the root yield. This addition had positive impact on the number of bacteria of the genus AzCh and the quantity of organic carbon in soil.

Opis:
The research aimed at an assessment of health quality of radish originating from Krakow open air markets. The health quality was estimated on the basis of an analysis of the content and distribution of heavy metals in radish as well as its sanitary state. Heavy metal contents (Zn, Cu, Cd, Pb, Cr and Ni) were assessed in radish flesh, skin and leaves after dry mineralization and the ash dissolving in HNO3 using ICP-EAS method. Microbiological analyses comprised determining Coli and Salmonella bacteria count as well as the number of anaerobic and spore forming bacteria (Clostridium perfringens). Heavy metal contents in the studied radish fluctuated widely depending on the analyzed part. The highest contents of zinc, copper, chromium, lead and cadmium were assessed in leaves, lower in the skin and the lowest in radish flesh. Tested radish did not meet the consumer standards for zinc and cadmium. Presence of Coli bacteria was noted in 36 % of samples, Salmonella bacteria in 10 % and Clostridium perfringens only in 2 %.
Celem badań była ocena jakości zdrowotnej rzodkiewki pochodzącej z placów targowych Krakowa. Jakość zdrowotną oceniono na podstawie analizy zawartości i rozmieszczenia metali ciężkich w rzodkiewce, jak i jej stanu sanitarnego. Zawartość metali ciężkich (Zn, Cu, Cd, Pb, Cr, Ni) w miąższu, skórce i liściach rzodkiewki oznaczono metodą ICP-EAS po suchej mineralizacji i roztworzeniu popiołu w HNO3. Analizy mikrobiologiczne obejmowały oznaczenie liczebność: bakterii z grupy coli, bakterii z rodzaju Salmonella oraz beztlenowych bakterii przetrwalnikujących Clostridium perfringens. Zawartość metali ciężkich w badanej rzodkiewce wahała się w szerokim zakresie w zależności od analizowanej części. Największą zawartość cynku, miedzi, chromu, ołowiu i kadmu stwierdzono w liściach, mniejszą w skórce, a najmniejszą w miąższu rzodkiewki. Badana rzodkiewka nie spełniała norm konsumpcyjnych pod względem zawartości cynku i kadmu. Obecności bakterii grupy coli stwierdzono w 36 % próbkach, bakterii rodzaju Salmonella w 10 %, a Clostridium perfringens tylko w 2 %.

The objective of the pot trial carried out at the area of the Slovak University of Agriculture in Nitra was to determine the impact of dry pig manure produced on the sawdust bedding and sawdust litter on the level of nutrients’ mobility in the soil and sugar beet yield. The achieved results showed that one month after the sawdust and manure application to the soil, the contents of mobile nutrients (Nan, P, K, Ca, Mg) in soil were lower than in the control unfertilized treatment. The sawdust litter immobilized nutrients more considerably than manure. Four months after the manure application into soil, its immobilization effect was not evident. On the contrary, the manure increased the mobile nutrients content in soil. In the second year of experiment the immobilization effect of sawdust litter was proved even four months after its application into soil. The application of manure increased considerably the beet root yield. The maximum root yield was determined in the treatment where the highest dose of manure was applied. The minimum root yield was detected in the treatment where the highest dose of sawdust litter was applied.

Opis:
The objective of the following three-year small-plot experiments was to determine the impact of a dose and application date of the biostimulator Mg-Tytanit (MgTi) on the formation of winter oilseed rape phytomass and its titanium cont ent. In the trial the biostimulant Mg-Tytanit containing 8.5 g of titanium in 1 liter was used. The experiment consisted of 5 treatments: 0 – control treatment without MgTi; 2xTi0.2 – two applications of MgTi in the dose of 0.2 dm3 ha-1; 3xTi0.2 – three applications of MgTi in the dose of 0.2 dm3 ha-1; 2xTi0.4 – two applications of MgTi in the dose of 0.4 dm3 ha-1; 3xTi0.4 – three applications of MgTi in the dose of 0.4 dm3 ha-1. The BS was applied in spring during two or three different growth stages: BBCH 50, BBCH 59, BBCH 66. The first plant sampling was carried out shortly before the first application of BS (BBCH 50). The second, third and fourth sampling were taken 2 – 3 weeks after the application of Mg-Tytanit (BBCH 59, BBCH 66, BBCH 71). The results showed that the biostimulator MgTi, regardless of its dose and application date, resulted in a higher weight of the aerial and underground phytomass. All the MgTi applications had impact on the winter oilseed rape yield increase. The seed yield was increased by 0.3 to 0.63 t ha-1. Higher yields were achieved in the treatments where MgTi was applied three times in comparison with the treatments, where it was used twice. The oil content in rape seeds was increased significantly only if MgTi was used in the total doses 0.8 and 1.2 dm3 ha-1 in the single application dose 0.4 dm3 ha-1. The oil content value was increased by 0.94 % and by 0.82 %. The oil production per hectare was increased after each use of MgTi, i.e. regardeless of the dose and date of its application. The highest Ti content in the aerial phytomass was 68.5 mg kg-1 and in the underground phytomass it was 247.1 mg kg-1.
