Abstract:

The effect of different origin organic fertilizers on agrochemical indicators of typical medium-humic chernozem in hazelnut plantings in the conditions of Ukrainian Southern Steppe was studied. There were used cattle manure, chicken droppings, Biofertilizer No. 1 (the combination of sewage sludge, winter wheat straw, phosphate-mobilizing bacteria Microbacterium barkeri), Biofertilizer No. 2 (the combination of sewage sludge, sunflower seed husks, phosphate-mobilizing bacteria Microbacterium barkeri), and native sewage sludge in the study. It was found that different origin organic fertilizers effected on the main agrochemical soil indicators increasing. The content of easy hydrolyzable nitrogen in soil increased from 84.0 mg kg-1 in control up to 98.0 mg kg-1 in the tests, mobile phosphorus – consequently from 138.75 mg kg-1 in control to 306.30 mg kg-1 in the tests, and potassium from 108.40 mg kg-1 in control to 166.90 mg kg-1. In addition, the organic matter content increasing from 3.76% (control) to 4.18% (tests) in the soil was detected. The express biosensor analysis of the fertilized soil showed a variation of the average ecotoxicity indicator from 0.92 to 1.41 which could be classified as a “low” common pollution level. It also detected an elevated zinc content in soil samples fertilized by Biofertilizer No. 1 and native sewage sludge. It proves that organic fertilizers based on sewage sludge applying can allow for overcoming the zinc deficit in Ukrainian soils. The advantages of Biofertilizers No. 1 and No. 2 were identified in respect to other studied organic fertilizers. New biofertilizers using allows soil nutrient content increasing, soil biological activity enhancement, which resulting in improvement in crop yield, and environmental enhancement.

Abstract:

According to the European Environment Agency, in 2021, 93 percent of ammonia was released into the environment due to agricultural activities. Almost half of the pollutants were released from cowsheds. The next significant source of pollution is liquid and/or solid manure storage facilities. Many dairy farms use liquid manure systems, but inevitably there is some solid manure produced in every cattle farm. Ammonia emissions increase when air penetrates the top layer of the manure pile. This is the reason why it is recommended to reduce the surface area of the manure piles that contact with open air. Straw, peat, sawdust, or other materials can be used as bio-covers. The purpose of this study is to determine the efficiency of bio-covers while covering solid manure. Experimental studies were carried out in field conditions, covering solid cattle manure with a > 10 cm thick layer of chopped straw. As the results show, chopped straw reduced ammonia emissions by up to 44.49 percent, but the emission declination rate is 1.85 times higher during the period when NH3 volatilization is the most intensive.

This study was designed to determine the effect of different doses of biochar (B) 5.10, 20 t ha-1 alone and mixed with manure (F) 10 t ha-1 on turnips. The results showed that the OM (organic matter) rate had a maximum of 93.7% for (B20*F) and a minimum of 14.5% for (F); the CEC (cation exchange capacity) showed a maximum of 32.2% for (B10*F) and a minimum of 0.2% with (B5*F) compared to the control (T) and finally the pH to be increased with a maximum value of 11.2% for (B20*F) and a minimum value of 1.7% for (F) compared to (T) (≤ 0.01).
For the chemical parameters of the turnip, the maximum nitrogen rate was 93.8% with (B10) and 2% for (B20). The highest value for phosphorus was recorded in (F) and a minimal value in (B5) (≤ 0.01). The potassium level was high 4.2% for the treatment (B20*F) with the lowest value of 4.4% for (B5) and (B10) compared to (T) (0.05).
For the yield components, the fresh weight of the most important bulb was obtained with (F) with the value of 116.8% and minimum weight of 0.4% in the treatment (B5). The highest bulb length value was 36.8% in (F) and the lowest was 0.5% obtained with (B20*F). The bulb diameter was the largest in the treatment (F) and the smallest was 4.8% in (B20). Finally, the fresh weight of the leaves showed a maximum of 106.9% in (F) and an increase of 6% in (B20) compared to (T) (≤ 0.01).

Abstract:

The present research is dedicated to the study of anaerobic co-digestion process of different biomass materials. Anaerobic co-digestion of digested sludge, grass silage, haylage and cattle manure was evaluated in mesophilic tank reactors in the lab-scale experiment. Twelve laboratory scale tank reactors (1.5 L) were used during the incubation period of 45 days. First triplet of reactors was fed with pure digested sludge and the other three with different mixtures having the volumetric ratios of 30/35/25/10, 40/30/20/10 and 50/25/15/10 for digested sludge/corn silage/grass haylage/cattle manure. Methane production was analyzed for all lab-scale reactors individually. The resulting specific methane production of above-mentioned batches was 336.34, 238.1 and 233.23 LSTP[CH4] kg-1[TVS], respectively. Other results such as cumulative biogas and methane yield, volumetric biogas and methane yield, volumetric biogas and methane yield per day were also assessed. These results had the highest meaning when complex substrate had no more than 30% of inoculum.

Abstract:

In the context of increased intensification of production and disruption of established ties between livestock and crop farms there is an urgent need to introduce novel, more efficient, economically viable and environmentally sound techniques of animal and poultry manure processing. As a part of the ongoing work on implementation of best available techniques (BAT) in various sectors of Russian economy, agriculture included, the bioconversion technology of organic waste in a drum-type bio-fermenter was considered as one of BAT candidates, which is most adapted to the natural and climatic conditions of North-West Russia and feature the minimal environmental impact. The main purpose was to investigate the influence of bioconversion of solid fraction of cattle manure on selected microbial parameters and parasitic purity in the raw material, semi-finished and final products. The study was conducted in the IEEP Organic Waste Bioconversion Laboratory on a patented drum-type bio-fermenter. After 18 hours the digested material self-heated to 55 °C, i.e. the lower limit of the range of thermophilic microbial activity. By the 30th hour after the experiment started the temperature had reached the maximum level of 71 °C, then it dropped to 62–66 °C and stabilized in this range. 48 hours after the temperature reached 55 °C, the content of coliform bacteria reduced to acceptable limits, and that of Enterococcus dropped more than 10 times. After 120 hours the digested product was completely disinfected.

Abstract:

The possible use of energy crops and aquaculture for bioenergy production has only recently become a research target, so there is little information on their properties and advantages. The aim of this study was to investigate the possible use of cup plant, as well as marine and freshwater algae (Scenedesmus sp. and Chlorella sp.) for biogas production. Research of a batch anaerobic digestion process at a mesophilic temperature were performed using wet wastewater sludge, cattle manure, fresh microalgae biomass and dry marine algae, cup plant biomass and mixtures of these materials. The highest biogas yield (541.28 ml g-1 VS) was obtained by using a new feedstock from the microalgae Scenedesmus sp. biomass. That yield was 1.4 times higher than the biogas yield from cattle manure and 15% lower than the biogas yield from wastewater sludge. It was found that adding microalgae biomass to a cattle manure substrate increases biogas production approx. 1.5 times. The highest methane concentration in biogas produced from microalgae ranges from 64.87% to 66.66% and exceeds the methane amount (64.26%) in biogas produced from wastewater sludge. The methane amount in biogas produced from cattle manure, cup plant and marine algae biomass is lower than 60%. In addition, it was found that it is possible to produce 5,092.3 m3 of biogas or 113 GJ of energy from 1 ha of harvested cup plant biomass.
