The article presents the results of Efluent organic fertilizer research. We used pig manure to obtain biomass (residues); it also provided biogas production after digestion. We used a biogas system located in LLC Organic-D for fermentation of biomass, it is located in the village of Sutysky, Tyvriv district, Vinnytsia region, Ukraine. The prospects of using similar types of fertilizers have been analyzed. Agrochemical and microbiological analysis was carried out in specialized laboratories for organic fertilizers. It has been established that the peculiarities of animal maintenance and feeding have affected the chemical composition of manure, it is confirmed by the data of microbiological and agrochemical analysis, in particular the level of its invasive contamination. The total number of fungi in the samples ranged from 118.8 to 193.8 thousand / g. The species composition of pathogenic fungi in manure were pathogenic species of the genus Alternaria and Fusarium by 3.2%, and the number of pathogenic species of fungi not rejuvenated manure was 66.7% (from the genus Fusarium - 9.5%, from the genus Aspergillus - 57.2%). Among saprotrophic fungi there are species from the genus Penicillium (Penicillium janczewskii Zaleski, P. raciborskii Zaleski, P. simplicissimum (Oudem.) Thom, P. chryzogenum Thom) from the genus Acremonium (Acremonium Kiliense Grutz). In the first sample (fermented) the number of saprotrophic fungi from the genus Penicillium was 87.1%, from the genus Acremonium 6.5%. In the second sample (without fermentation), the number of saprotrophic fungi of the genus Penicillium decreased to 33.3%. Saprotrophic fungi of the genus Acremonium were not observed. Among toxin-forming species, Penicillium janczewskii Zaleski, Penicillium chryzogenum Thom, Aspergillus flavus, Alternaria alternata (Fr.) Keissl. and Fusarium oxysporum (Schlecht.) Snyd. et Hans) were observed. A high amount of toxin-forming fungi was found in undiluted manure - 85.7%. In the updated material, the percentage of toxin-forming fungi was lower by 16.1%. Organic fertilizer Efluent was characterized by an alkaline reaction (pH 8.5), high moisture content (98.4%), significant content of nitrate nitrogen (18.2 mg/kg), copper (4.6 mg/kg), zinc (32 mg/kg), manganese (20 mg/kg) and iron (120 mg/kg). Therefore, the use of this fertilizer will provide plants with both macro and microelements, and its application on acidic soils will also reduce the level of soil acidity. Prospects of its use in soils with the raised acidity of a soil solution are given.

The study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig manure, PiM) applied at 15 t ha-1 equivalent rate on the soil and growth performance of okra grown in a degraded ultisol. The treatments (CoM; CoM; PiM and Control unamended) were laid out in a completely randomized design and replicated three times. Animal manure application had significant effects on soil properties. Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil. It is recommended that farmers use ample (15 t ha-1) ) quantity of animal manures to increase their crop yields, which invariably will enhance their income.

The Impact

The focus of the present study is a small biogas power plant for anaerobic fermentation of several types of animal waste raw materials used for biogas production. The impact of some of the characteristics of substances such as composition, temperature, humidity, and pH of the mixture in the bioreactor has been considered. The above is vital for optimizing the fermentation process, and also to improve the biogas production process. The plant is located in Northeastern Bulgaria and the raw liquid manure is supplied by several neighboring small farms. The annual quantities of raw waste are as follows: cow manure - 1252 t / a; chicken manure - 427 t / a and pig manure - 639 t / a. The manure is collected in a preliminary tank and then pumped to the bioreactor. The fermenter itself is a hermetically sealed and thermally insulated tank where constant temperature is maintained. It is equipped with a stirring system, which helps the mixing and homogenization of the substrate. The tests were performed during three charges of the installation. The fermentation takes approximately 23 up to 25 days. The experiments were performed during the summer and autumn seasons when the ambient air temperature varies from 28 to 45 °C. The biogas can be used as an energy carried as the obtained organic fertilizer is suitable for agriculture purposes.

This article discusses a new method of utilizing carbon-containing waste into biogas with the addition of a biological active additive Mefosfon to the substrate in order to accelerate the process of obtaining biogas and preserve nutrients in the final product - organic fertilizer. The experiments were carried out in a small-volume biogas plant (MBU) without air access in a heat-insulated reactor filled to 2/3. The results of numerical studies of the conversion products of cattle manure are presented. The manure was kept in the reactor for 7 days. The use of the drug Mefosfon in ultra-low concentrations (10-4) made it possible to obtain a useful product in the form of high-quality organic biofertilizers and biogas. The conducted microbiological analysis of the experiments showed that in the experiment with the use of the drug Mefosfon, the content of enterococci and bacteria of the Escherichia coli group were lower than in the experiment without the drug Mefosfon. Bioconversion of the organic component of the substrate allows the use of waste in agriculture as organic fertilizers. Such processing can significantly reduce the dry weight of the treated organic waste and reduce the content of pathogenic microorganisms Salmonella spp. and Enterococcus spp., bacteriophage FX174, Ascarissuumova. Mefosfon reduces the time of maturation and neutralization of carbon-containing agricultural waste, which indicates the prospects of its use. After processing waste in a small-volume biogas plant, there are no pathogenic pathogenic microflora, helminth eggs, weed seeds, nitrites and nitrates. The final nitrogen content of the Mephosphon treated substrate is higher than that of the untreated substrate. The acidity values in the substrate pH 6.7 in the untreated and 7.5 in the treated substrate. Studies have shown that when the drug Mefosfon is added to the substrate, the release of biogas begins on 1-2 days and lasts up to 7 days. In this case, the biogas yield increases up to 25% compared to the use of the control substrate without the use of the Mefosfon preparation. The drug has found application in plant growing, animal husbandry, reclamation of contaminated soils

Worldwide breweries are known to use large volumes of water. Between 10 and 20m3 of water yields 1m3 of beer. This translates to over 90% of wastewater. The world produced 1.94x108m3 of beer in 2018. Of the total production 1.48x107m3 of beer were produced from Africa with Uganda contributing up to 4.1x105m3. Uganda’s major producing industries being Uganda Breweries Limited and Nile Breweries Limited. Uganda’s brewery sector generates between 3.69x106 to 7.79x106m3 of wastewater annually that could otherwise be of importance. This wastewater is characterized by high organic matter content with COD, BOD and TSS ranging between 2,000 to 10,000mg L-1, 1,200 to 7,000mg L-1 and 2,901 to 3,000mg L-1 respectively. Whereas little information has been published regarding the current use of wastewater in Uganda by the Key players, elsewhere in the world the wastewater has been treated for re-use using Anaerobic Sequencing Batch Reactor and membrane bioreactors, for electricity generation using microbial fuel cell and for biogas production using Veolia Bio Bed Technology. The generated sludge has successfully been used as an Organic Fertilizer and a raw material for Organic Fertilizers production in different parts of the world. The process by-products such as spent grain, spent hops and surplus yeast have been used majorly in fertilizers and animal feeds. The purpose of this review article was to explore potential uses of the wastewater in that could apply for Uganda.

Antibiotic Residues

Recycling of organic wastes in agricultural ecosystems to partially substitute chemical fertilizer is recommended to improve soil productivity and alleviate environmental degradation. However, livestock manure- and sewage sludge-derived amendments are widely known to potentially carry antibiotic residues. The aim of this study is to investigate how substituting organic fertilizer for chemical fertilizer affects soil quality and antibiotic residues in agricultural soil, as well as their tradeoffs. A field experiment was conducted with the different treatments of pig manure and sewage sludge as typical organic fertilizers at equal total nitrogen application rates. The analysis of variance showed that the increments on the levels of residual antibiotics in the agricultural soils due to organic substitution for chemical fertilizer by pig manure and sewage sludge were observed. The antibiotic residues ranged from 13.73 to 76.83 ng/g for all treatments. Partial organic substitution significantly increased the sequestration of antibiotics in agricultural soil by 138.1~332.5%. Organic substitution will also significantly improve soil quality, especially for nutrient availability. Based on principal component analysis, organic substitution will strongly affected soil quality and antibiotic contamination. Pearson’s correlation showed that soil physicochemical properties had significant correlations with concentrations of antibiotics in soil, indicating organic fertilizers can promote the persistence of antibiotics in soil by modifying soil quality. To balance the benefits and risks, appropriate management practices of organic fertilizers should be adopted.

AbstractNortheastern Thailand relies on agriculture as a major economic activity, and has used high levels of agrochemicals due to low facility, and salty sandy soil. To support soil recovery and sustainable agriculture, local farmers have used organic fertilizers from farmed animal feces. However, knowledge about these animal fecal manures remains minimal restricting their optimal use. Specifically, while bacteria are important for soil and plant growth, an abundance and a diversity of bacterial composition in these animal fecal manures have not been reported to allow selection and adjustment for a more effective organic fertilizer. This study thereby utilized metagenomics combined with 16S rRNA gene quantitative PCR (qPCR) and sequencing to analyze quantitative microbiota profiles in association with nutrients (N, P, K), organic matters, and the other physiochemical properties, of the commonly used earthworm manure and other manures from livestock animals (including breed and feeding diet variations) in the region. Unlike the other manures, the earthworm manure demonstrated more favorable nutrient profiles and physiochemical properties for forming fertile soil. Despite low total microbial biomass, the microbiota were enriched with maximal OTUs and Chao richness, and no plant pathogenic bacteria were found based on the VFDB database. The microbial metabolic potentials supported functions to promote crop growth, such as C, N and P cyclings, xenobiotic degradation, and synthesis of bioactive compounds. Pearson’s correlation analyses indicated that the quantitative microbiota of the earthworm manure were clustered in the same direction as N, and conductivity, salinity, and water content were essential to control the microbiota of animal manures.
