Opis:: In this study three different types of manure (bird, cattle and sheep) with three doses (10, 20 and 30 g) were mixed with soil to investigate and compare the different performance of energy generation as well as provides the ways of increasing the efficiency for such an application. The mixed soil was incubated for ten days after wetting with tap water as needed, then the voltage and current readings were taken every twenty-four hours for ten days. Experiment results indicated that 30 g cattle manure was the best use for energy generating purposes, delivering a voltage peak of 7.4 mV and current of 0.48 mA compared to 7.4 mV; 0.34 mA for bird manure and 6.56 mV; 0.32 mA for sheep manure. Cattle manure produced the highest peak for voltage with all doses and was therefore the best to use. In general, all treatments provide enough voltage to power the LED bulb successfully.

Opis:: 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:: Celem badań była ocena zagrożeń mikrobiologicznych odorowych i pyłowych w pomieszczeniach inwentarskich na fermach drobiu. Ponadto określono skuteczność biopreparatu i ekstraktu roślinnego Yucca schidigera w obniżaniu stężenia wybranych związków odorowych generowanych przez pomiot drobiowy oraz w higienizacji pomiotu. W pomieszczeniach inwentarskich zapylenie powietrza było wysokie i kształtowało się na poziomie 1,44 mg/ m³; dominowała frakcja pyłu PM₁₀. Zarówno w pomiocie drobiowym oraz pyle osiadłym stwierdzono wysoką liczebność bakterii i grzybów na poziomie 10⁶–10¹⁰ jtk/g. Na fermie drobiu nie odnotowano przekroczenia limitu dotyczącego liczby bakterii i grzybów w powietrzu. Odnotowane stężenia frakcji PM_2,5 i PM₁₀ były 18–20 razy wyższe niż dopuszczalne dla 24-godzinnej ekspozycji określone przez Światową Organizację Zdrowia. Wśród odorowych związków lotnych na fermach drobiu dominowały: amoniak, akroleina, metyloamina, kwas octowy, aldehyd octowy i formaldehyd. Ich stężenia były zmienne w zależności od rodzaju fermy i etapu cyklu produkcyjnego. Dopuszczalne stężenie amoniaku w powietrzu zostało przekroczone na fermie kur niosek I i II, natomiast stężenie dwutlenku węgla przekroczyło dopuszczalną wartość w trzecim etapie cyklu produkcyjnego na fermie brojlerów III i było zbliżone do limitu na fermie niosek I. Cytotoksyczność mieszaniny związków odorowych wobec komórek kurzych LMH maksymalnie wynosiła 45,7%, potwierdzono ją zmianami morfologicznymi komórek po działaniu związków odorowych (amoniaku, di- i trimetyloaminy). Biopreparat mineralno-mikrobiologiczny wraz z ekstraktem Yucca schidigera zmniejszał ogólną liczbę drobnoustrojów o około 1 rząd wielkości w pomiocie drobiowym i obniżał stężenie związków odorowych o 37–70% w zależności od związku. Zastosowanie kolejno ekstraktu Y. schidigera, a następnie po 2 dniach biopreparatu może być skutecznym sposobem ograniczania zagrożeń mikrobiologicznych i odorowych na fermach drobiu.
The aim of the study was to evaluate the microbiological contamination, odour and dust concentration in poultry farms. In addition, the eﬀectiveness of biopreparation and Yucca schidigera plant extract in manure hygienisation and selected odorous compounds removal was determined. The airborne total dust concentration at poultry production premises averaged 1.44 mg/m³ with a high percentage of the PM₁₀ fraction. High number of bacteria and fungi at 10⁶–10¹⁰ CFU / g. was determined in both poultry manure and settled dust. Poultry farm’s air limits of the bacteria and fungi number have not been exceeded. Reported concentrations of PM_2,5 and PM₁₀ fractions were 18–20 times higher than acceptable for a 24-hour exposure determined by the World Health Organization. Volatile odorous compounds dominant in poultry farms were: ammonia, acrolein, methyl amine, acetic acid, acetaldehyde and formaldehyde. The concentrations are variable depending on the farm type and stage of the cycle production. The permissible concentration/ exposure limits of ammonia in the air has been exceeded in the laying hens farms I and II, while the concentration of carbon dioxide exceeded the limit value in the third stage of the cycle production on broiler farm III and was close to the limit for laying hens farm I. The maximum cytotoxicity of odorous compounds mixture tested on chick liver hepatocellular carcinoma cell line LMH was 45.7%. It was confirmed by cells morphologic changes after the odorous compounds treatment (ammonia, di-, and trimethylamine). Mineralmicrobial biopreparation with Yucca schidigera extract reduced the total number of microorganisms by 1 logarythmic unit in poultry manure and decreased concentration of odorous compounds by 37–70% depending on the compound. The use in sequence Y. schidigera extract, and then after 2 days biopreparation can be an eﬀective way to reduce microbiological and odorous hazards on poultry farms.

Opis:: Animal biomass is an important substrate in the anaerobic digestion process. The implementation of a waste technology for energy production, such as the production of biogas from animal waste, has been recognized in many countries as one of the best ways to achieve the Sustainable Energy Development Goals. Without a systematic review of resources and accurate estimation of available sources in terms of the amount of potential electricity, it is impossible to manage biomass rationally. The main aim of the article was to present a new tool for assessing the biomass of animal origin and estimating its potential energy through a computer database, which will be widely available in the end of 2020 to show results from the calculation using the database. This tool is configured to enter the data on the developed and undeveloped biomass resources in production of farm animals in rural areas in Poland. Calculations from the database show the biogas potential of swine and cattle manure and slurry in Poland, which is approximately 5.04 billion m3, with a 60% share of methane in biogas. It is the value of approximately 3.03 billion m3 of methane. It is worth underlining that slurry and manure are not high-energy substrates; therefore, it is necessary to introduce more energetic substrate streams to improve the biogas plant efficiency.

Opis:: Organic plant cultivation, especially those intended for human consumption, poses new requirements for gardening. It is recommended to use organic slow-action fertilizers, which provide doses of nutrients essential for plants for a long time. Particularly valuable fertilizers are those that arise within the household, due to their high quality and the absence of costs associated with their purchase and transport. Organic matter contained in the food industry waste or arising in households, in the absence of contamination by other types of waste, can be used for self-production of organic fertilizer. The paper presents the results of testing organic fertilizers, which you can make yourself, destined for the cereal plants. The experimental fertilizers were made from coffee spent grounds (CSG) and ash from the thermal conversion of biomass (A), and the components limiting the amount of pests in the form of leaves and flowers of tansy (Tanacetum vulgare L.). The fertilizer can be used at the time of planting and sowing, because of the slow release of nutrients. Moreover, the addition of leaves and flowers of tansy helps to protect the seedling due to the content of essential oils. As a comparison, the horse manure and rabbit droppings fertilizers were used. Such fertilizers can be prepared independently, which leads not only to reducing the weight of biodegradable and mineral waste, but also provides the ability to generate financial savings of the household and promote organic gardening. Fertilizers made from a mixture of CSG and A support the implementation of good agricultural practice and sustainable development.

Opis:: The aim of the study was to determine the long-time effect of meliorating doses of hard coal ash (0, 100, 200, 400, 600 and 800 t ha-1) on the content of some elements in soil with the application of different organic substances: manure, straw and bark. Nineteen years after the application of ash there was still an increase in the total content of all elements in soil. Its magnitude depended on soil horizon and it was highest in the humus horizon. The increase in the content of nutrients was, in general, proportional to the applied doses of ash. In the surface layer of soil, the increase was particularly high for sodium and subsequently for calcium, magnesium, sulphur, potassium and phosphorus, arranged in the order of decreasing values. The content of elements in deeper soil layers was significantly lower than in the 0–25 cm zone. A gradual reduction in the content, together with the increase in depth, was recorded only for magnesium and sulphur. The lowest concentration of phosphorus and calcium was detected in the 51–75 cm layer, while in the case of potassium it was in the 26–50 cm zone. The substances introduced into the soil in order to reduce the impact of ash generated by hard coal combustion did not exert any significant impact on the content of elements 19 years following their application.

Opis:: The purpose of this research was to improve the diamond post-mining soil quality using a bioremediation composting method based on the cow manure and organic waste from a traditional market. This research was conducted for: 1) identifying the conditions for temperature, pH and moisture during the composting process; 2) analyzing the difference of variations in composition and the best composting durations. The bioremediation method used is open windrow composting, divided into four composition variations, namely variation A (100% soil); B (75% soil: 25% compost); C (50% soil: 50% compost); D (25% soil: 75% compost). The variations of composting duration are 15^th and 30^th days. From the result of two-way ANOVA test, it can be concluded that there is no significant difference in the decrease of Fe value due to the variations in composition ratio and duration of composting.

Opis:: Eggplant is a vegetable that is widely cultivated in Indonesia. Fertilization is one of the most influential factors to increase eggplant productivity. The research to improve the eggplant productivity through the application of various nitrogen nutrient sources in an integrated nutrient management system and an intercropping system with cabbage was carried out from June to December 2019 in Wonorejo, Poncokusumo-Malang. The study was conducted using a randomized block design (RBD) with 21 treatments and was repeated 3 times. The treatments were D0 = Control (180 kg N) and (D1–D20), which were various combinations of inorganic N fertilizers, manure, and microbes (EM and PGPR). Observations included the number of leaves and stem diameter of eggplant, number of cabbage leaves, number of fruit per plant, fruit weight (per plant, per hectare, and per fruit), and Land Equivalent Ratio (LER), soil analysis before and after the research. The results showed that the combination of 75% inorganic fertilizer + 20–30 t·ha-1 manure + 10–20 ml·l-1 microbe (EM / PGPR) in the eggplant – cabbage intercropping system increased the growth and yield of eggplant, with fruit weights ranging 1.86–2.35 kg·plant-1 or 40.88–53.17 t·ha-1, and LER value was 1.94–2.04.

Opis:: The experiment was carried out in 2016–2018 in Łańcut, in the Rzeszów Foothills. The effect of fertilization using the sheep manure vermicompost on sweet potato of early cultivar (Carmen Rubin) and selected soil characteristics was investigated. The experiment was based on the method of randomized sub-blocks performed in four replications. Two cultivation technologies were used, in which the differentiating factor was fertilization applied or the lack of it. In the first technology (I nf – without fertilization), no fertilization was used in the years of research; in the second technology (II fv – fertilization with vermicompost), the vermicompost made from the sheep manure was applied. The vermicompost increased the yield of sweet potatoes of Carmen Rubin cv. and the share of large tubers in the yield structure. It also influenced the increase of organic carbon and total nitrogen in the soil as well as the content of available forms of phosphorus, potassium and magnesium. Some of the studied soil properties were less favorable compared to their condition before the start of the experiment.

Opis:: Anaerobic digestion consists of the biological decomposition of organic waste under anaerobic conditions by various types of microorganisms. The purpose of this study was to evaluate the effect of the fermentation starter of methanogenic bacteria on the anaerobic digestion of cattle manure in a bioenergy plant. The effect of various methods (physical, microbiological and chemical) on the digestion of cattle manure was studied under mesophilic (35°C) and thermophilic (50°C) modes. The results of the study showed that the content of volatile fatty acids and the pH of the medium was in the optimal range, the yield of methane biogas (CH4) during anaerobic digestion at 35°C was 0.45 m3/kg and at 50°C was 0.58 m3/kg. The data obtained indicate that the thermophilic mode (50°C) of anaerobic digestion of manure effectively affects the yield of methane biogas. Based on anaerobic digestion in mesophilic mode, a fermentation starter of methanogenic cultures adapted to thermophilic conditions was obtained. According to cultural and morphological characteristics, the cultures were assigned to the genera Methanopyrus and Methanococcus. The results of a study on the effect of the fermentation starter of methanogenic bacteria in fermented manure at 50°C showed that with an increase in the dose of the fermentation starter, the methane-forming ability of anaerobic bacteria increased and the process of methane biogas release intensified (from 0.36 m3/kg to 0.79 m3/kg). Besides, the dose of methanogenic fermentation starter based on Methanopyrus and Methanococcus isolates (28 kg) was determined. When the bioenergy plant is launched in thermophilic mode, the release of biogas increases by 2.2 times, and the digestion period decreases to 10 days.

Opis:: Because of the potential threat for development of plants, resulting from the occurrence of too high cobalt contents in soil environment, a study was undertaken aiming to determine the effect of increasing soil contamination with cobalt (0, 20, 40, 80, 160, 320 mg·kg-¹ of soil), following the application of neutralising substances (farmyard manure, loam, charcoal, zeolite and calcium oxide), on the soil pH, hydrolytic acidity, total exchangeable bases, cation exchange capacity and the base saturation. In the series without neutralising substances added, soil contamination with the highest doses of cobalt resulted in a decrease in pH, in the total exchangeable bases, in the cation exchange capacity, and in the base saturation, and in an increase in the soil hydrolytic acidity. Of the applied neutralising substances, farmyard manure and particular calcium oxide had the greatest effect on the analysed soil properties. The application of the substances resulted in an increase in the soil pH, in the base exchange capacity, in the cation exchange capacity and in the base saturation and also in a decrease in the soil hydrolytic acidity. The other substances had no, or a small, effect on the studied soil properties.

Opis:: Płytkie wody podziemne są szczególnie podatne na zanieczyszczenie azotanami pochodzenia rolniczego. W pracy podjęto próbę rozpoznania kierunku przestrzennych i czasowych zmian stężenia azotanów w płytkich wodach gruntowych, zalegających pod warstwą piaszczystej gleby, w miejscu okresowego składowiska obornika i w jego najbliższym otoczeniu. Badania przeprowadzono w latach 2009–2015 na terenie gospodarstwa rolnego ukierunkowanego na produkcję mleka, położonego w północno-zachodniej części środkowego basenu Biebrzy, w województwie podlaskim. Stanowisko badawcze zlokalizowano na skraju pola, na którym corocznie uprawiano kukurydzę i gdzie na przełomie lat 2010/2011 i 2014/2015 okresowo składowano obornik. Próbki wód gruntowych pobierano korzystając z 7 studzienek kontrolno-pomiarowych, w odstępach miesięcznych, 4-8 razy w roku. Uzyskane zbiory wyników zawartości azotanów poddano analizie statystycznej z wykorzystaniem analizy wariancji z testem Kruskala-Wallisa. Przeprowadzono również analizę korelacji stężenia azotu azotanowego w wodzie z różnych punktów badawczych oraz analizę jego regresji w kolejnych latach badań. Średnie, roczne stężenie azotu azotanowego w próbkach wód gruntowych pobieranych z poszczególnych studzienek kształtowało się szerokim zakresie wartości od 1,1 do 101,8 mg N-NO₃∙dm^–3. W zdecydowanej większości przypadków (86%) wielokrotnie przekraczało ono graniczną wartość dla III klasy jakości wód podziemnych czyli 11,3 mg N-NO₃∙dm^–3. Zatem badane wody należy zaliczyć do wód zanieczyszczonych bądź zagrożonych zanieczyszczeniem. Ponad to w ujęciu przestrzennym i czasowym, średnie, roczne zawartości azotanów w badanych próbach wód gruntowych, pobieranych ze studzienek zainstalowanych na terenie stanowiska badawczego charakteryzowały się znacznym zróżnicowanym przestrzennym, miały odmienne nasilenie jak też kierunki zmian w czasie, w niewielkim stopniu były ze sobą skorelowanie.
Shallow groundwater is particularly susceptible to contamination by nitrates from agricultural sources. The paper attempts to recognize the direction of spatial and temporal changes in the concentration of nitrates in shallow groundwater, lying under a layer of sandy soil, in the place of a temporary manure storage place and in its immediate vicinity. The study was conducted in the years 2009–2015 on farm focused on milk production, located in the north-western part of the central basin of Biebrza, in Podlaskie voivodeship . The research stand was located at the edge of the field where maize was grown every year and where manure was periodically stored at the turn of 2010/2011 and 2014/2015. Groundwater samples were collected using 7 control and measurement wells, on a monthly basis, 4-8 times a year. The obtained results of nitrates content were subjected to statistical analysis using the analysis of variance with the Kruskal-Wallis test. The analysis of correlation of nitrate nitrogen concentration in water from various research points and analysis of its regression in subsequent years of research was also performed. The average annual concentration of nitrate nitrogen in groundwater samples collected from individual wells was in the wide range from 1.1 to 101.8 mg NO₃∙dm^–3. In the vast majority of cases (86%) it repeatedly exceeded the limit value for the third class of groundwater quality, or 11.3 mg N-NO₃∙dm^–3. Thus, the tested water should be classified as polluted or at risk of contamination. In addition, in spatial and temporal terms, the average annual nitrates content in the tested groundwater samples collected from wells installed on the research site was characterized by a significant different spatial, has a different intensity as well as directions of changes in time, to a small extent correlated with each other.

Opis:: An impact of poultry farms on the environment caused by ammonia emission from chicken manure has been studied. A negative impact minimisation method by adding natural sorbents to the bedding composition has been proposed. The optimum natural adsorbents compositions (clinoptilolite and palygorskite) for adding to the bedding as well as the optimum mixture ratio of these adsorbents to chicken manure mass have been determined. The optimum conditions for obtaining granulated organic-mineral fertiliser of prolonged action based on this composition have been studied. In the result of the research data analysis a technological scheme for organic-mineral fertiliser production based on chicken manure and a mixture of natural adsorbents have been proposed.

Opis:: The results of research on the activation of the microflora by using post-harvest green manure crops were presented. As a result of the conducted studies, the positive effect of sidereal crops of Raphanus sativum and Phacelia tanacetifolia on activity increase of microflora in black soil with little humus was revealed. Application of post-harvest siderates increased the number of non-sporous species of bacteria and actinomycetales, contributed to improvement of soil environment under the influence of siderates, which had a positive effect on creating more comfortable conditions for growing potatoes. The usage of green fertilizers had a positive influence on microbiology activity of soil.

Opis:: The field experiment was carried out at The Experimental Station of Plant Varieties Protection in Szczecin Dąbie. The experiment aimed at evaluating the influence of slurry with and without increasing doses of PRP FIX preparation on some soil fertility indicators after test plants harvest. The contents of determined macronutrients in the soil were higher in objects where slurry was applied with addition of 8 kg or 12 kg of PRP FIX per 1 m³ as compared to those with exclusively mineral fertilization or slurry. The soil after test plants harvest contained more N, Corg., P, K, Mg, Ca, S, and available forms of P, K, Mg and SO₃, in relation to levels before experiment establishment. In general, more soil fertility indicators were recorded in objects treated with the slurry along with PRP FIX preparation and additional PK nutrition (series II) as compared to series I. Differences in macronutrients in the soil due to the fertilization system applied were diverse, however, they not always were significant.
