Opis:: Sewage sludge (SS) is a byproduct of wastewater treatment which is commonly used as fertilizer in the world. However, due to the possible contamination with heavy metals, xenobiotics and fecal pathogens, its application on fields is not so common in Poland. A safer alternative for agricultural use is the SS produced by food industry in small „inhouse” wastewater treatment plants, as substances that are used in its production are usually less harmful. As pretreatment of industrial wastewater is required before dumping the wastewater into common stream, the SS is an abundant byproduct that needs to be managed in an environmentally friendly and cost effective manner. Because the water content in SS is usually high, the dosage and logistics are problematic and thus we propose converting the sewage sludge into solid granular fertilizer in the vermicomposting process. Not only are the weight and volume of product decreased as a result, but also the nutrients such as N, P, and K become concentrated and made more accessible for plants. The SS is also further stabilized and less prone to produce odors and becoming putrid. The aim of this study was the in-depth analysis of the SS process vermicomposting with biochar. The SS was acquired from a local soft drink factory wastewater treatment plant. The batches of SS were inoculated with 20% mature vermicompost and E. fetida worms. Instead of typical bulking agents (like woodchips or straw) powdered biochar was used in the concentrations of 5, 10 and 15% as it exhibits beneficial influence on the process and increase the value of the final product.

Opis:: Polycyclic aromatic hydrocarbons (PAHs) are introduced to the environment from anthropogenic and natural sources. The most significant natural source of PAH are wildfires and volcanic eruptions. The PAHs occurring in the soil mostly bind to the root system of plants. Phytodegradation, specifically rhizospheric degradation, can reduce the PAH levels in soil with the help of plants roots. A pot experiment was conducted to study the effect of application of soil amendments on the PAHs level in the burnt soil (BS). The aim of this study was to assess the effect of application of soil amendments (compost, biochar, and bentonite) on the PAHs level after performing experiment with two grass species (Lolium perenne, Festuca rubra). Biochar and compost turned out to be the most effective amendments, regardless of the used grass species. Phytomanaged BS without added amendments also demonstrated the potential for PAH dissipation, but only in the case of Festuca rubra. It has been proven that the application of soil amendments together with the test grass species induced important changes in the BS properties (alteration of soil pH with related change of Kow of individual PAHs; root system on which soil microorganisms thrive) which evoked an increased bioavailability of PAHs.

Opis:: Food waste has recently received attention due to its environmental, economic and social impacts. Final processing of food waste encounters a number of technical challenges, arising from weak physical structure of food waste with weak porosity, high content of water, and low carbon-to-nitrogen relation. This study deals with the research of food waste processing in households by using an automatic device. The main objective of the study was to assess the toxicity of the end-product produced by an automatic device. The research included 10 experiments. The input foundation consisted of common food waste generated in household kitchens. Following its processing, the end-product was tested in a pot experiment for the germination capacity and biomass increase in different concentrations. The end-product was mixed with the reference soil in concentrations 5/95, 30/70, 50/50 (tested/reference substrate). The testing included three different plant species, i.e. Sinapis alba L., Hordeum vulgare L. and Cannabis sativa L. The germination capacity of plants and their increase in biomass were evaluated after 21 days. The increase in biomass was monitored by using the Before-After-Control-Impact method. The plants developed much better without the end-product additive to the soil substrate than with its small addition. The best germination capacity in the case of end-product addition was observed in the concentration ratio 30/70 in all plants. In spite of this, the highest increase in biomass was recorded in the concentration ratio 5/95. This might have caused the occurrence of mould in the pots. The test shows that the end-product made of food waste is toxic to plants; therefore, it is not recommended for direct application as a soil amendment.

Opis:: The aim of the study was to analyse the potential of production and utilization of biochar as a marketable product in agriculture for Turkey. Towards this aim, the distribution of ar- able land, crop residues and soil types of Turkey were identified. The biochar production potential was evaluated depending on prominent residual biomass streams in Turkey. In addition, how much biochar would be needed for arable soil types found in Tur- key was estimated according to previous studies which investi- gated the effect of biochar on similar soil taxonomy and/or plant grown. Total crop production is focused on southern, western and central Anatolia, although the arable lands of Turkey prevail in seven regions. The residues of wheat, barley, corn and cotton stalk, tea, banana, hazelnuts and forest were found to be higher than other residuals in different regions and they could be suitable for biochar production. Furthermore, it was highlighted that the low water holding capacity of soil, alkalinity, salinity and soil pollution impeded the crop productivity. Although, the biochar produced from prominent residues was one-fiftieth less than that of total estimated amount of biochar needed for arable soils, it ob- viously improves the plant growth and soil characteristics, when used together with fertilizer, especially for zonal and intrazonal soils. At this point, it could be focused on the long-term field ex- periments due to determine the special and productive addition rate of biochar for Turkey, and biochar addition to the soil could be channelled into threatened priority arable lands by the public authorities.

Opis:: The sugarcane stalk borers, Sesamia spp. (Lepidoptera: Noctuidae) are the most destructive sugarcane insect pests in Iran. The efficiency of Telenomus busseolae Gahan (Hymenoptera: Scelionidae) used alone or in combination with silicon fertilization was investigated for controlling the sugarcane stalk borers under field conditions. The treatments were: a combination of silicon plus multiple releases of 2,500 T. busseolae, and multiple releases of 5,000, 2,500 and 1,250 T. busseolae alone. Plots receiving no soil amendment or parasites were included as the controls. Three weeks after the first application of each treatment, 100 shoots were selected randomly from each plot and the percentage of dead heart was determined. Then, three months after the first application of parasites, the percentage of stalks damaged, the percentage of internodes bored, and the level of parasitism were determined. Finally, at harvest the percentage of stalks damaged, the percentage of internodes bored, and sugarcane quality characteristics were determined. Results indicated that the efficiency of parasitism increased when combined with an application of silicon fertilizer. The release of 2,500 T. busseolae followed by an application of silicon fertilizer decreased dead hearts to 4%, while 12% dead hearts was observed in the control plots. For the combination treatment, the percentages of stalk damage were 1.5% and 17.2%, at 3 weeks and 3 months after time release, respectively. However, the percentages of stalk damage were 35.2% and 51% when no treatment was applied. Cane quality was significantly higher with the application of silicon fertilizer plus the release of 2,500 T. busseolae, followed by releasing 5,000 Hymenoptera. The level of parasitism was also greater when parasites were released in combination with an application of silicon. We conclude that biological control by egg parasitoids can be enhanced with concurrent applications of silicon fertilizer as a soil amendment and thereby creating a more robust, Integrated Pest Management (IPM) program of stalk borers in Iranian sugarcane fields.

Opis:: Silicon plays an important role in providing tolerance to various abiotic stresses and augmenting plant resistance against diseases. However, there is a paucity of reports about the effect of silicon on bacterial and viral pathogens of plants. In general, the effect of silicon on plant resistance against bacterial diseases is considered to be due to either physical defense or increased biochemical defense. In this study, the interaction between silicon foliar or soil-treatments and reduced bacterial and viral severity was reviewed. The current review explains the agricultural importance of silicon in plants, refers to the control of bacterial pathogens in different crop plants by silicon application, and underlines the different mechanisms of silicon-enhanced resistance. A section about the effect of silicon in decreasing viral disease intensity was highlighted. By combining the data presented in this study, a better comprehension of the complex interaction between silicon foliar- or soil-applications and bacterial and viral plant diseases could be achieved.

Opis:: Biochar has been extensively studied as a soil amendment to reduce nutrients losses. However, the comparative effectiveness of biochar adsorption capacity for ammonium (NH4 -N), nitrate (NO3 -N), and phosphate (PO4-P) remains unknown. In the present study, the effects of feedstock (banana stem and coconut shell) and temperature (300, 500, and 700°C) on biochar adsorption ability for NH4-N, NO3-N, and PO4-P were investigated and fitted by three adsorption models, viz Freundlich, Langmuir, and linear. Freundlich (R2 = 0.95–0.99) and Langmuir (R2 = 0.91–0.95) models were found suitable for adsorption of NH4 -N. The maximum adsorption capacity (Qm) for coconut shell biochar increased with pyrolysis temperature (Qm = 12.8–15.5 mg g-1) and decreased for banana stem biochar (Qm = 12.9–9.7 mg g-1). In the case of NO3 -N adsorption, Freundlich (R2 = 0.82–0.99) and linear model (R2 = 1.00) were found suitable while Langmuir model showed much less contribution, similarly adsorption of PO4-P, was not supported by these three models. The minimum concentrations required for adsorption of phosphate were recorded as 36, 8, and 3 mg L-1 using pyrolyzed biochar at the temperatures of 300, 500, and 700°C, respectively. These results indicate that the feedstock and pyrolysis temperature, as well as aquatic nutrient concentration, were important factors for the adsorption of inorganic nitrogen and phosphorus.

Opis:: Root vegetables have greater risk of metal contamination from compost application to soil than other horticultural crops. Moreover, soil organic amendments pose potential environmental hazards. The objective of the present study was to examine the heavy metal uptake in different tissues (petiole, blade, skin, pulp) of Raphanus sativus exposed to organic amendments doses. The impact of the above materials on heavy metal concentration of the soil and plant development parameters were also evaluated. A pot experiment was established with eight treatments arranged in a randomized complete block design and four replicates. Co-compost of sewage sludge and olive wastes at 100, 200, 300 m3 ha–1, composted olive leaves, olive tree pruning wastes, olive mill pomace and poultry manure at 100, 200 m3 ha–1, commercial liquid organic fertilizer at 50 Kg ha–1 with or without inorganic NPK fertilization and a no fertilizing control, were applied to plants. The results showed that sewage sludge application strongly increased the yield and improved radish size cultivated in silt loam soil. The edible radish part had the lowest Fe, Mn, Cu, Zn, and Cr content, whereas the highest Mn, Cu, Zn, Cr was found in the blade and increased Fe, Ni, Pb were recorded in the skin. Organic treatments gave higher Fe, Mn, Cu, Zn amount in both aerial plant tissues compared to the control soil, while Ni, Pb, Cr of all the radish parts were not affected by treatments. This study suggested that organic amendments application gave low permissible levels of all metal content in radish tissues and increased radish productivity. Therefore, organic materials used herein can be applied for normal plant growth without metal contamination of the plant and the soil.

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.
