Opis:
Nowadays the increasing number of animal enterprising depending on the needs of human population growth and nutrition need that was occurred during the production of animal breeding have revealed the manure issue. Manure from animal barn, when not stored properly, causes environmental problems including odour and visual pollution, and could create environmental pollution problems. On the other hand, random storage of manure on the land outside animal barn as a result of climate parameters such as rainfall results in leakage of manure and can cause contamination of water resources. In Turkey, animal manure obtained from animal barns is almost not utilized and is accumulated outside. Manure which is produced in animal barn to be used for agricultural purposes must be stored in the areas which prevent the spread of in the environment . Thus, the loss of minerals in the soil plant available forms are contained in manure, will be prevented. In addition, due to the nutrients and microorganisms, surface and underground water resources can be a factor in polluting and may create a risk to animal health and environmental pollution. The study has been carried out by determining the 4950 cattle breeding enterprises around the Eğirdir, Beyşehir Burdur and Salda lakes in the Lakes Region. About 50000 cattle are bred in the 4950 cattle breeding enterprises in the study area. However, of these animals 43502 are bred for commercial purposes. When the values in literature are taken into account, the daily manure amount that would be put forth has been calculated as 1500 tons. It has been concluded that animal manure which is the output of animal breeding enterprises will result in environmental pollution, water resource pollution as well as posing a threat to life in general by mixing with water resources such as underground water, lakes etc. when deposited haphazardly in stacks that are not well managed. As a result, we believe that our producers should be well informed regarding manure management prior to experiencing such problems.

Opis:
Organic farming is a holistic production management system that promotes and enhances environmental quality including biodiversity, bio-geo-chemical cycles and soil floral and faunal activities. One of the energy resources developed during recent years are the application of organic sources such as biogas slurry, blue green algae, compost, green manure farmyard manure, vermicompost and seaweed liquid fertilizer. During decomposition, these organic manures yield many organic compounds and organic acids as well as antibiotic substances as an intermediate product. Mangrove/Halophytes forest has an important ecological and socio economic value to man. In India, Tamil Nadu has a coastline of 950 km. Extensive mangrove wetlands are located in Pichavaram of Cuddalore district and Muthupet of Thanjavur district. It is reported that the nutrient values of halophytes were higher when compared to green manures (glycophytes). The objective of the present study is to highlight the efficacy of halophytic compost which are normally available in coastal areas on growth and yield parameters in pulse varieties. Various combinations of halophytic composts used, Suaeda compost + farmyard manure + phosphate solubilising bacteria treatment showed an increased in biomass and yield, number of root nodules and microbial activities when compared other halophytic compost and control. This study shows the feasibility of using halophytic composts in the coastal area to improve soil fertility and productivity.

Opis:
Passive aeration co-composting using four mixtures of chicken manure and swine manure at 1:0, 1:1, 3:7 and 0:1 with sawdust and rice husk was carried out to study the effects of co-composting on the physicochemical properties of the organic materials. The experiment, which lasted 66 days, was carried out in bins equipped with inverted T aeration pipes. The results showed that nutrient losses decreased as the proportion of chicken manure in the mixtures decreased for saw dust and rice husk treatments. This indicates better nutrientst conservation during composting in swine than chicken manure. Manure mixtures with rice husk had higher pile temperatures total carbon and total nitrogen losses, while manure mixtures with saw dust had higher total phosphorus loss and carbon to nitrogen ratio. Composts with rice husk demonstrated the ability to reach maturity faster by the rate of drop of the carbon to nitrogen ratio.

Opis:
A study of new pig manure treatment and filtration process was carried out. The advantage of the worked out technology is the method of incorporation of crystalline phase into solid organic part of manure. The obtained new solid phase of manure contains about 50% of crystalline phase forming a filtration aid that enables high effectiveness of manure filtration. The filtration rate of manure separation into solid and liquid fractions with pressure filter may achieve 1300-3000 kg/m2/h. The method makes it possible to maintain an overall average pollutant removal performance 90% for the chemical oxygen demand COD, > 99% for the suspended solids SS, to 47% for the total nitrogen content. The obtained results showed that the proposed technology being efficient and simple offers a possible solution to pig manure problems.

Opis:
Heavy metals and antibiotics resistance are intense public interest owing to their pollution in the environment and potential deleterious effects on human health. A total of 15 isolates of Bacillus subtilis, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli (50 manure garden soils) were tested for their resistance against certain heavy metals and antibiotics. Minimum inhibitory concentrations of Pb²⁺, Co²⁺, Cu²⁺, and Zn²⁺ for each isolate were also determined. B. subtilis, B. cereus, P. aeruginosa and E. coli exhibited high tolerance to minimum inhibitory concentrations of 3,200 μg/ml for Pb²⁺, 400 μg/ml for Cu²⁺ and Co²⁺, and 100 μg/ml for Zn²⁺ in agar plates. All the isolates were highly resistant to lead and they showed 100% growth in 3,200 μg/ml concentration. It was observed that all isolates were resistant to a wide range of antibiotics namely clindamycin, ceftazidime, aztreonam and vancomycin.

Opis:
The main objective of this study is to carry out a complex economic analysis of organic manure application. Researches were carried for years 2010-2015. Organic manure, a by-product of animal husbandry, is one of the oldest and most valuable materials in agriculture. The primary purpose of using organic manure is to improve soil fertility. Since the 90s, Hungary has been facing changes in the ownership of agricultural ventures, the number of big farms decreased and the amount of livestock was reduced in the main sectors of animal husbandry. Hungary, as a member of the European Union, has to conform to the current environmental protection regulations which also refer to the disposal of organic manure that can only be performed if significant investments are made. It can be concluded that the economic efficiency of organic manure application is primarily determined by transport distance and the specific transport method. In addition, the establishment of manure containers can be considered to be unproductive investments which affect the economic efficiency of using organic manure negatively.
Głównym celem artykułu jest kompleksowa ocena ekonomiczna stosowania obornika na Węgrzech. Badania dotyczyły lat 2010-2015. Stwierdzono, że efektywność ekonomiczna stosowania nawozu organicznego zależy przede wszystkim od sposobu transportu i odległości na jaka jest transportowany. Ponadto wykazano, że tworzenie płyt obornikowych może być uznane za inwestycję nieopłacalną, która negatywnie wpływa na efektywność ekonomiczną użycia nawozów organicznych.

Opis:
Heavy metals determination in manures provides beneficial information to predict the availability and the potential contamination of environment. Therefore, a study was carried out to investigate heavy metals changes in livestock manure during a co-composting process. The metals were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate precipitated and residual forms by extracting with 0.5M KNO3, de-ionized water, 0.5M NaOH, 0.05M Na2EDTA and 4M HNO3, respectively. During the extraction process, the amount of metals remained highly dependent on an extraction method and stage of manure composting. Extractions released heavy metals contents in the final composted manure as Zn > Cu > Pb > Cr > Ni > Cd. Irrespective of the days of composting, extracting agents differed in the order HNO3 > Na2EDTA > NaOH > KNO3 > H2O for all heavy metals. Higher concentrations of heavy metals were observed during the early stages of composting. Conversely, there was a progressive increase in the concentrations of K, Ca and Mg during composting of manure. Total C in the manure reduced with composting days.

Overcoming of technological barriers in methane fermentation of substrates including poultry manure derived from poultry-breeding industry is regarded as one of strategic trends in biogas-technology development. The essential limitations and possibilities of such substrates for biogas production is presented here. It should be emphasized, that biogas production based on poultry manure from industrial-scale farms is effective solution of important ecological problem with simultaneous production of green energy and efficient solution of odours emission from the poultry breeding farm. Methane co-fermentation of post-processed bedding premixed with poultry manure solves, at least partly, problem of correct C/N ratio in the substrate mixture.

Long-term application of fertilizers can change the chemical composition of the soil environment. Our objective has been to determine total amounts of trace elements (Cu, Mn, Zn, Cd and Pb) in the top layer of soil after 34 years of annual applications of organic and mineral fertilizers. The first experiment was set up in 1972 on lessive soil, while the second one was started in 1973 on brown soil. The same crops were grown in both experiments. Bovine manure and slurry were applied in the first experiment, while the other one involved the application of swine manure and slurry. Slurry was applied at two different doses. One dose of slurry was applied together with manure and mineral fertilization in amounts balanced according to nitrogen. The other dose of slurry was determined so that it brought to soil the same amount of organic carbon as introduced with a manure dose. Manure and slurry were also applied in combination with phosphorus and potassium fertilizers in amounts equal half the content of these components used delivered through exclusive mineral fertilization. The total metal content was assessed using the atomic absorption spectrometry method, with prior mineralization in a 1:1 mixture of nitric and chloric acid. The application of fertilizers over many years increased the content of trace elements. The actual effect varied between the analyzed soil types, depending also on the type of fertilizer and the dose of slurry. The average content of Cu, Cd and Pb was 13.8% higher in lessive than in brown soil, while the amount Mn was lower by as much as 32.7%. Among the doses balanced with respect to nitrogen, the effect of manure caused an increase in the Mn, Zn and Ni content in lessive soil, as well as Cu and Pb in brown soil compared to the application of the slurry dose balanced with manure according toorganic carbon. Mineral fertilizers did not increase the content of the analyzed metals as much as manure, with the exception of Cu and Pb in lessive soil and Ni in brown soil.

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.
