The technology of accelerated processing of non-pigmented pig manure in organic fertilizer

Cattle and pig manure contain useful mineral nutrients (N, P, and K) and are therefore used as organic fertilizer. However, excessive applications of manure can cause environmental problems and threaten animal and human health because these materials also hold significant amounts of heavy metals, particularly Cu and Zn. To assess the potential risk due to the increased concentrations of heavy metals (Cu, Mn, Zn, and Cr) in a harvested crop, two maize hybrids were grown in pots on four different soils with three different fertilisers (urea, pig manure, and cattle manure). Both soil and manure characteristics influenced the heavy metal concentrations in the plant shoots. Organic fertilisation strongly interacted with the soils and, in general, reduced the shoot content of Cu, Mn, and Zn. A preliminary assessment of the heavy metal balance of the agricultural systems based on the intensive livestock production and maize cultivation showed that the potential soil enrichment of the long-term application of livestock manure arises mainly from the application of pig slurries that have a high content of Cu and Zn. The time required to apply an amount of metal that is equal to the initial soil content is 60–300 years for Zn and 240–450 years for Cu, depending on the soil type and the initial heavy metal content.

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.

Abstract The most effective doses of the modified organic-mineral fertilizer (MOF), produced from non-contact pig manure in the conditions of the Rostov region for the purpose of soil reclamation, were determined. Experimental studies were carried out to determine the most effective dose of MOF based on non-contact pig manure. The dependence of the spring wheat yield on the use of a modified organic-mineral fertilizer based on liquid waste from pig farms fermented bird droppings and mineral fertilizers is determined. The equivalence of the effect of a modified organic-mineral fertilizer based on liquid waste from pig farms and fermented bird droppings, introduced in an equivalent dose, on plant biomass was established. When comparing the effects of different types of fertilizers, their toxicity was not established. The introduction of a modified organic-mineral fertilizer based on liquid waste from pig farms at a dose of 2 t / ha provided the highest biomass yield of 34-day-old plants of spring wheat of the “Zlata” variety, which reached 0.9 g/vessel and was 28.5% higher than the control value. A new organic mineral fertilizer with a pH of 8-10, with an organic content of up to 73% per dry weight, can be used for supporting the quality of liming and improving soil.

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.

AbstractThis paper presents properties of filtrate obtained from pig manure using the AMAK treatment process, which includes the mineralization of macro- and microfertilizer components by the hydrolyzing of organic matter into forms that are bioavailable to plants. Filtration produced two products, sediment and filtrate. The quality of the filtrate allowed for its use as a substitute of water to irrigate crops. Concentrations of heavy metals are very low and therefore the quality of the filtrate fully complies with European standard concerning fertilizers. The used mineralization process practically eliminated odors from the filtrate. The reduction of specific odor emission by 99.1-99.5% in samples taken from above the filtrate, respectively compared to the odor concentration found in samples taken from above raw pig manure. Sediment could be used as raw material for production of mineral-organic fertilizer. Filtrate and filtration sediments analyses show that the majority of nitrogen and other fertilizing compounds included in raw pig manure remains in sediment.

Optimal Approach

A person’s desire to improve the quality of life makes the individual reconsider the attitude towards the quality of consumed food. Despite the fact that the prices of natural products are several times higher than of those grown with the use of herbicides and pesticides, organic food is getting more popular in all countries around the world. Such products can only be received when crops are grown using organic farming methods, one of the principles of which is to increase the amount humus in the soil. The preservation of soil fertility can be ensured using the methods of modern biotechnology, which are based on the vital activity of microorganisms capable of converting organic matter from animal waste into environmentally friendly fertilizers. In animal husbandry, the main portion of agricultural waste is cattle and pig manure. The most economical way to dispose it is to use methane digestion, when biogas and fertilizers are obtained. However, when processing manure bedding materials in biogas reactors, the straw fractions and lignin–containing components of the bedding are not decomposed by bacteria and pass into the solid fraction of the fermented biomass unchanged, which is a problem. The infiltration of such an unprocessed residue into the soil leads to deterioration of soil properties. Thereby, the solid fraction of the fermented biomass requires additional processing to improve its agrochemical properties. Most expedient is to use vermicomposting, that is, process organic waste with the help of earthworms. Biohumus, or vermicompost, is one of the end products of this method. In this work, we studied the procedure of processing the solid fraction of fermented pig manure by Eisenia foetida compost worms (red Californian worm). In order to determine the optimal approach of vermicomposting, the experiment was planned. As a result, a high–quality organic fertilizer was obtained – biohumus –and the optimal parameters of the environment were determined(pH and humidity), at which the worms have the highest biological activity.

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.
