Abstract

We consider the manure removal system, which is used in most pig farms being built and reconstructed at present in Ukraine, and it has been discovered that there are major mistakes during the baths construction in the correct geometry and depth, and therefore discusses their rules of operation. If the baths geometry is wrongly executed, for instance, if the slope is made to slant toward the bottom of the tub filler drain pipe, which in itself is unacceptable, or not properly executed in the form of a special pit steps towards the neck drain, and etc., then a number of problems is inherent of its exploitation. The basic requirements for laying fused-pipe is compliance with its slope. The considered equipment must be equipped with pumping stations to pump manure. The pumps for pumping manure: submersible sewage pumps and dry-installed in the mine and long sewage pumps with electric or PTO shaft of a tractor were analyzed. Attention was paid to the designing of modern equipment for the distribution of manure waste into fractions. The classification of manure storage and the basic requirements for their placement and arrangement was carried out, and recommendations are made for the designing of pumping stations, to select pumps for the pumping stations and the design during the modern construction and reconstruction of old pig farms.

Abstract

Basal Stem Rot (BSR) disease caused by Ganoderma lucidum (Leys) Karst. is the most destructive disease and a major constraint in coconut production. Fifty five endophytic strains of bacteria were isolated from coconut roots of different regions. Among the isolates, EPC5 (Endophytes coconut), EPC8, EPC15, EPC29, EPC52 and Pf1 (Plant growth promoting rhizobacteria) promoted the rice seed ling growth in roll towel and pot culture method. EPC5 (Plant growth promoting endophytic bacteria), Pf1 and Trichoderma viride (Plant growth promoting fungus) effectively inhibited the G. lucidum growth in vitro. When bioagents along with farm yard manure (FYM) were heaped for different days interval the population was increased in twenty days both in sterilized and unsterilized conditions.

Abstract

Biogas production has a big potential to provide clean energy. To evaluate the future production and maturity of biogas technology the generalized Weng model was proved to be effective, due to it has the minimum error. The simple algorithms to determine its parameters have been proposed. The simulation results for China, USA, and EU have been presented. The quantity and quality analysis for biogas feedstock has been carried out. Energy Return on Energy Invested (EROEI) indicator for different biofuels was considered. According to analysis done biogas from maize residue and chicken manure has high EROEI. Shannon Index was suggested to evaluate the diversity of feedstock supply. Biomass energy cost indicator was grounded to be used for feedstock energy and cost assessment. Biogas utilization pathways have been shown. Biogas boilers and CHP have the highest thermal efficiency, but biogas (biomethane) has the highest potential to earn as a petrol substitute. Utilization of biogas upgrading by-product (carbon dioxide) enhances profitability of biogas projects. Methods to assess the optimal pathways have been described.

Abstract

Agricultural utilization of appropriately stabilized sewage sludge appears to be the most rational method of its utilization, even though there is no agreement among scientists as to the impact that these wastes can exert on the maintenance of the soil biological balance. That is why the objective of the performed field-laboratory experiments was to determine the developmental dynamics of selected groups of microorganisms in a grey-brown podzolic soil fertilized with acceptable and unacceptable doses of sewage sludge and farmyard manure. Numbers of six groups of microorganisms were determined at various dates associated with the development of spring barley (total bacterial number, number of actinomycetes, fungi, bacteria from the Azotobacter genus and Pseudomonas j/uorescens) as well as pathogenic bacteria from the Sa/111011ella genus. The selected groups of microorganisms were determined on selective media by the plate method. The obtained research results showed that, in the majority of cases, the applied levels of organic fertilization did not have a significant impact on the numbers of microorganisms in the soil. Therefore, it can be said that the application of both acceptable and unacceptable doses of sewage sludge in the form of fertilizers failed to disturb the biological balance of the examined soil. In addition, the results of the performed experiments indicated that the agricultural utilization of sewage sludge should be forestalled by a sanitation process (e.g. composting) in order to get rid of' pathogenic bacteria, especially bacteria from the Salmonella genus.

Abstract

The paper presents microbiological characteristics of sewage sludge derived from the mechanicalbiological sewage treatment plant and farmyard manure as well as composts manufactured from them. In the performed experiment, four types of composts were analyzed. The first of them comprised the sewage sludge alone, the second one - was made up only of farmyard manure, while the remaining composts were prepared by mixing the above-mentioned bio-wastcs in the following proportions: 75% sewage sludge+ 25% farmyard manure and 50% sewage sludge + 50% farmyard manure. The next stage of experiments involved analyses of the composts incubated with soil. The following assays were carried out in the experimental composts and mixtures of soil and composts: counts of Salmonella sp., E. coli, Clostridium perfringens, total counts of bacteria, fungi and actinomycetes on selective media employing the plate method. The performed investigations revealed that the composting process resulted in complete riddance of the Salmonella sp. and reduction in the numbers of the remaining groups of microorganisms. Therefore, it can be said that the composted sewage sludge was suitable for the utilization for agricultural purposes in accordance with the Directive of the Minister of Agriculture and Rural Development of October 2004. Moreover, it was found that, as early as 60 days after the introduction of composts into the soil, counts of the majority of the analyzed groups of microorganisms (with the exception of actinornycctcs and E. coli), including pathogenic bacteria from the C. perfringens genus, were found reduced. The obtained research results proved that the introduction of bi o-wastes into the soil may decrease survivability in the natural environment of certain pathogens; hence it is a good method of utilization of this organic material.

Abstract

This paper presents the results of fractionation of particulate and soluble organic matter in a mixture of maize silage and cattle manure (49:51% volatile solids) that was used as a feedstock for anaerobic digestion. The extended Weender’s analysis was adapted to measure raw protein, raw lipids, fraction of carbohydrates (including starch, cellulose, hemicelluloses) and lignin. The content of individual fractions in composite, Xc (as kg COD kg-1 COD) was: 0.111 proteins, 0.048 lipids, 0.500 carbohydrates and 0.341 inerts. The biodegradability of Xc was 68%. Based on material balance, the carbon concentration in Xc was 0.0326 kmol C kg-1 COD, whereas nitrogen concentration 0.0018 kmol N kg-1 COD. The estimated pH of the feedstock based on acid-base equilibrium corresponded to the actual value (pH 7.14).

Abstract

The aim of this study was to implement ADM1xp model to simulate behavior of anaerobic co-digestion of maize silage and cattle manure. The accuracy of ADM1xp has been assessed against experimental data of anaerobic digestion, performed at OLR = 2.1 gVS dm-3·d-1 and HRT = 45d. Due to the high number of parameters in ADM1xp, it was necessary to develop a customized procedure limiting the range of parameters to be estimated. The best fitting of experimental to simulated data was obtained after verification of 9 among 105 stoichiometric and kinetic parameters. The values of objective function (Jc) ranged between 0.003 (for valerate) and 211 (for biogas production).

Abstract

One of the methods of sewage sludge disposal, which is based on its fertilizing properties, is its use in nature, e.g. in farming (if all the permissible standards are met). However, the sludge used for soil fertilization might also contain heavy metals, pathogenic microorganisms, thus causing contamination in soil foundation and deterioration of the conditions for development of indigenous organisms. Particular threat is posed by the existence of drug-resistant microorganisms in sewage sludge. This problem has not been researched in detail yet.

The authors of the present study aimed to determine qualitative changes in drug-resistant microorganisms in sandy soil fertilized with selected sewage sludge. Sewage sludge after different types of drying process (natural and solar) was added to the degraded sandy soil. The effect of the methods of sewage sludge drying on concentration of drug-resistant microorganisms in soil fertilized with the sludge was analysed.

The study demonstrated that sewage sludge dried naturally in drying beds pose threat to soil environment and, potentially, to people and animals which have contact with fertilized soils. In sandy soils fertilized with these types of sewage sludge, pathogenic forms which exhibit resistance to first-line antibiotics can be found.

Abstract

The objective of this work was investigation of the growth dynamics of proteolytic bacteria and the enzymatic activity in soil for the cultivation of maize (Zea mays L.), as well as the maize yield under application of some selected organic fertilizers. Intensity and the direction of the developed changes in the soil depended on the type of applied organic fertilizer, the size of its dose introduced into the soil and on the developmental phase of the grown plant (maize). On the basis of obtained results it was found that all tested organic substances stimulated the activity of proteases. Yields ofmaize as raw material for silages obtained from soil fertilized with sewage sludge were similar to those obtained after the application of pig slurry and they exceeded maize yields harvested from other ferti I ization objects.

Abstract

The Directive on National Emission Ceilings specifies the reduction of ammonia (NH 3) emissions among other air pollutants, which is most significant for the agricultural sector. The ammonia emission limit set for Hungary was a 10% reduction by 2020, while the target of 32% should be reached by 2030 compared to the 2005 reference year. The paper presents the results of a survey on pig production technology in Hungary from 97 domestic farms. The study aims to know the level of implementation of reduction techniques in livestock production and manure management and highlights the need for further improvements in this production sector. The research found that the application of ammonia reduction techniques was not considered widespread, either in livestock buildings or in manure storage (treatment) and during field application. For almost all (more than 90%) pig production groups, the housing systems were the reference without additional emission reduction. For manure storage, farms have insulated storage under the current regulation, however, significantly more emission reduction technologies were in the variant without cover or crust. Slurry spreading was mainly used with manure application techniques, but more emission-friendly injection and band spreading were also emerging. Besides the expected immediate incorporation, a high proportion of manure was applied between 12 and 24 hours or even after 24 hours. In the studied elements of manure management, significant improvements are needed in applying techniques to reduce ammonia emissions. Effective results can be achieved even by shortening the time between manure application and incorporation with efficient work organization.

Abstract

In 2021, pak choi production in Indonesia was 727.47 Mg, marking an increase of 8.2% compared to the 2020 production, which was 667.47 Mg. Therefore, there is a clear need for cultivation improvement, particularly through the implementation of organic fertilisers. This study aimed to investigate the impact of liquid organic fertiliser (LOF) derived from fish waste and duck manure on the growth and yield of the pak choi plant ( Brassica rapa. L. var. Nauli F1). A randomised block design factorial was used with two factors and three replications. The first factor considered was LOF from fish waste, comprising three levels (LOF 0 = control, LOF 1 = 25 cm 3∙dm –3 of water, and LOF2 = 50 cm 3∙dm –3 of water). The second factor focused on duck manure fertiliser (DMF) and involved four levels (DMF 0 = control, DMF 1 = 3.7 kg∙plot –1, DMF 2 = 5.55 kg∙plot –1, and DMF 3 = 7.4 kg∙plot –1). The results showed that the application of LOF from fish waste positively influenced the growth and yield of pak choi, with the most effective treatment observed in LOF1 (25 cm 3∙dm –3 of water). However, the application of DMF did not yield a significant difference in its effect on the growth and yield of the pak choi plant. The control treatment (DMF 0) reported comparable results and the combination of LOF from fish waste and DMF did not show a significant effect, with the most favourable findings observed in the LOF 2DMF 0 treatment (50 cm 3∙dm –3 and control).

Abstract

In the present study, the removal capacity of Pb(II) ions was investigated using the biomass of dried cattle manure in an aqueous solution. The biomaterials were characterized using Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS) techniques. The results reveal that the adsorption mechanism may be associated with the interaction between Pb(II) ions and functional groups through aggregation, coordination, ion exchange, microprecipitation, oxidation, and hydrophobicity. The bio-adsorption of the metal was analysed in discontinuous tests; the effect of temperature, pH, agitation, and adsorbent dose was evaluated. The maximum adsorption capacity was determined at pH 7.5, 18°C and 200 rpm. The bio-adsorption of Pb(II) was best fitted to the pseudo-second order model. The experimental data of the isotherm were adjusted to the models of Langmuir, Freundlich and Dubinin–Radushkevich; while Langmuir’s model related better to the experimental data forming a single layer at saturation. The rate of adsorption was rapid, reaching equilibrium after 25 min and removal of 96.8%. Thermodynamic parameters determined that the process was viable, spontaneous, and exothermic. The present study contributes mainly to demonstrating that a biomaterial prepared from bovine manure is a promising adsorbent for heavy metals such as Pb(II). It also reduces the environmental impact of this waste through the generation of greenhouse gases in countries that maintain intensive livestock. Another important aspect is the reduction of the micro- and macronutrients accumulation in soil and contamination of surface waters and aquifers by runoff and seepage during rainy periods.
