Conservation agriculture is becoming a priority for Ukraine as well as for many countries of the world. It is a known fact that high content of heavy metals in the soil impairs fertility and carries the risk of crops translocation. An agroecological effect of obtaining and applying organic-mineral fertilizers has been insufficiently studied so far. The purpose of the work is to determine possibilities to produce new organic-mineral fertilizers based on sewage sludge with enhanced adsorbing properties, to establish their agroecological efficiency. Methods. Field, laboratory-analytical, statistical-mathematical. Results. From the agroecological point of view, the production process of organic-mineral fertilizers based on the sewage sludge of Kharkiv is justified. It allows us to expand functional capabilities of reagents, enhancing adsorbing properties of heavy metals. It is proved the advantage of organic-mineral fertilizers over the traditional ones on chernozem typical. After fertilization, the content of total carbon in the soil increased, the content of humic acids increased by 1,5 – 2,8 times, fulvic acids – by 1,1 – 1,7 times, the total sum of humic substances – by 1,3 – 2,1 times compared with no fertilizer option. It is established that application of organic-mineral fertilizers promotes blocking of heavy metals in soil and prevents translocation to plant. Maximum yields of corn were obtained after the local application of granular organic-mineral fertilizers – the yield increase was 41% compared to the control, after introduction of bulk fertilizers – 32% compared to the control. Profit was $ 23 -36 per hectare. Conclusions. The process of organic-mineral fertilizers production on the basis of sewage sludge in Kharkiv is substantiated from the agro-ecological point of view. Agroecological and agrochemical efficacy of sewage sludge use as compared to organic and mineral fertilizers applied in equivalent doses separately was established on the typical heavy loam chernozem. After introduction of organic-mineral fertilizers based on sewage sludge a significant increase in the concentration of trace elements and heavy metals was found in the black soil but these indicators did not exceed the established maximum permissible concentrations. The implementation of the proposed technology will reduce bioavailability of heavy metals and their mobility in the soil which, in turn, impedes their accumulation in products. It is expected to increase soil fertility, crop yields and obtain environmentally friendly and safe products due to the stable composition of innovative fertilizers.

Annotation Purpose. Summarize the regulatory and technological requirements for the production of organic (organo-mineral) fertilizers on the base of sewage sludge. Methods. Analysis and generalization of the requirements of regulatory documents on the management of organic waste and their use as raw materials for the production of organic fertilizers and soil improvers. Results. The current legislative, departmental and regulatory documentary base in Ukraine concerning the treatment of sediment resulting from biological sewage treatment at municipal wastewater treatment plants for its further use in agriculture as fertilizers is analysed. Indicators are identified and analysed to determine the possibility, feasibility, efficiency and scope of organic fertilizers produced using sewage sludge. The analysis of changes in the content of organic matter and total nitrogen in the sewage sludge during its storage at the sewage treatment plant sites is presented. The technological feasibility of using sludge of different shelf life in composting production has been determined. Conclusions 1. The regulatory framework of Ukraine contains a sufficiently complete list of indicators that should be met by organic raw materials (sewage sludge) for further use as organic fertilizers. Some of these indicators – bio security and heavy metals content – can be improved in the composting process of fertilizers. 2. Fresh sediment, as well as sediment accumulated in the last late autumn and winter periods, is of main value for use as a raw material in the production of organic fertilizers. 3. The use in the production of compost sludge stored on sludge sites for a period of half a year or more requires special control of the process of decontamination. In this case, it is advisable to use additional means of wastewater decontamination. Keywords: heavy metals, manure, humus, decontamination, composting, organic fertilizers, sewage sludge.

Composted Sewage Sludge

Naturally infertile soils require large amounts of mineral fertilizers to obtain the desired crop yield. In the Cerrado region of Brazil, there is a need to investigate the potential of organic fertilizers to sustainably increase crop productivity and food security. A field study was conducted over two experimental seasons to evaluate the agronomic effectiveness of composted sewage sludge (CSS) as a fertilizer for soybean cultivation in infertile tropical soils. A 4 × 2 + 2 factorial randomized complete block design was applied with the following treatments: (i) CSS: 5.0, 7.5, 10.0, and 12.5 Mg ha−1 on a wet basis applied according to two different methods: whole area (WA) or between rows (BR); (ii) comparison with two alternative treatments: a control with no CSS and mineral fertilizer application, and an area treated with conventional fertilizers only. All the treatments were compared in terms of micronutrient concentrations in surface soil and plant leaves, plant development, crop productivity, and yield. Bi- (ANOVA, correlation matrix, and polynomial regression analysis) and multivariate (PCA, principal factor analysis) statistics were applied to determine statistical differences and relationships/observed variability among the treatments. Results showed that at higher CSS-WA rates: (i) soil and leaf micronutrient concentrations increased; (ii) there was an increase in soybean yield by 12 and 20%, respectively, as compared to control and conventional fertilization; (iii) soybean yield was 67% higher than the mean soybean yields for Brazil. Research outcomes confirm the benefits of CSS application on infertile agricultural soils in the Cerrado region, representing a strong alternative source of micronutrients in the CSS with respect to conventional fertilizers.

Final Destination

The use of sewage sludge to produce biochar is one of the best alternatives for the final destination of this material, allowing for reuse of nutrients and reducing the dependence on mineral fertilizers. Sewage sludge biochar (SSB) stands out as an enhancer of the physical, chemical and biological properties of the soil. The use of beneficial microorganisms such as Trichoderma spp. in combination with biochar may have a synergistic effect on the development of different plants and needs to be better studied. The SSB was produced from sewage sludge biomass (SS) obtained from the sewage treatment plant (STP) of the Federal District Environmental Sanitation Company (CAESB), Brasilia, DF, Brazil. The SSB was produced in an electric tubular furnace at 500 °C and showed the following characteristics: carbon (19%), nitrogen (2.3%), hydrogen (1.7%), specific surface area (52.5 m2 g-1), pore volume (0.053 ml g-1). An experiment was carried out in a greenhouse to evaluate the synergistic effect of SSB application (0.5% w/w) in combination with T. harzianum (TH) on soybean development. The treatments adopted were: (1) control – autoclaved soil, (2) TH, (3) SSB and (4) SSB + TH. The SSB was applied 15 days before soybean planting and the TH was applied to the soil two times, once at eight days before planting and the other at the time of planting. The SSB resulted in a 200% increase in the number of pods when compared to the exclusive application of T. harzianum. Application of SSB with T. harzianum increased germination by 20%, as well as a 70% increase in fresh and dry soybean mass in relation to the control. The agronomic indices evaluated in this study demonstrated that the use of SSB in conjunction with T. harzianum presents a synergistic effect, allowing for better development of the soybean plants.

In long-term stationary experiments under different soil-climatic conditions, an influence of mineral and organic fertilization on yield of winter wheat, spring barley and potato tubers was evaluated. Statistically significantly lowest grain yields of winter wheat (4.00 t/ha) and spring barley (2.81 t/ha) were obtained in non-fertilized plots at all experimental sites. In the case of potatoes, the lowest yield of dry matter (5.71 t/ha) was recorded in the control plot, but the result was not statistically significant. The manure-fertilized plot gave the average yield of wheat higher by 30%, of barley by 22%. Application of sewage sludge resulted in wheat yield higher by 41% and barley yield higher by 26% over control. On average, application of sewage sludge and manure increased the yield of potatoes by 30% over control. The highest yield was obtained after application of mineral fertilizers; average yield increased by 59, 50 and 36% in winter wheat, spring barley and potatoes, respectively. No statistically significant differences among the plots with mineral fertilizers were observed. At different sites, the yield of studied crops varied; however, the effect of fertilization on yield increments was similar at all experimental sites except for Lukavec. It is the site with the lowest natural soil fertility, and it showed the highest effect of the applied fertilizers.

Abstract Sewage sludge management in Poland is a relatively new field of waste management called “in statu nascendi”, the standards of which have not been recognized yet. It also requires the implementation of new solutions in the field of sewage sludge. So far, the most popular method of sewage sludge utilization has been landfill disposal. In line with the restriction placed on landfill waste with a calorific value above 6 MJ/kg introduced on 1 January 2016, agricultural use and thermal methods are particularly applied. Municipal sewage sludge may be successfully used in the cultivation of energetic plant plantations. The aforementioned waste could be treated as an alternative to traditional mineral fertilizers, which in turn might successfully provide valuable nutrients for plants. This paper illustrates the SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) associated with the use of sewage sludge from Świlcza-Kamyszyn WTTP (Podkarpackie Province, Poland) for agricultural purposes. This analysis could be useful in evaluating the utility of sewage sludge in perennial plant plantations in order to determine the appropriate waste management strategies.

Brazil is the world's largest producer of sugarcane, the main raw material used for the production of alcohol and sugar. The crop to achieve good levels of productivity demands high amounts of nutrients, which are usually supplied by the use of mineral fertilizers. An alternative for efficient fertilization is through the use of organomineral fertilizers. Such fertilizers consist of the mixture of organic fertilizers of animal or vegetable origin, and mineral fertilizers that undergo industrial processing. The industrial advance associated with the population increase has generated a large amount of solid waste and wastewater. One way to reduce the effects of environmental pollution from the presence of these solid wastes is through their treatment, giving rise to a pasty material, known as sewage sludge. Sewage sludge presents the potential to be used in the mineral nutrition of plants, both as fertilizer and as a soil conditioner. Biostimulants are natural or synthetic substances that can be applied directly to plants to increase yield and quality of crops of economic interest. Thus, the present review aims to report the study on the use of organomineral fertilizers from sewage sludge and biostimulant in sugarcane cultivation.

The dependence of mineral fertilizers, increasingly, has brought concern facing the increased demand and because it is a non-renewable mineral resource. The organic fertilization, exclusively, it is impractical in large scale, however, the combination of organic and mineral sources have already proved to be feasible, both from the point of view of nutrition of plants as well as in the aspect of recycling of urban and industrial waste by agriculture. This research had as objective to determine the efficiency of aorganomineral fertilizer formulated on the basis of sewage sludge in substitution of mineral fertilizer in the cultivation of sugar cane in environments with different levels of soil fertility. An experiment was conducted in greater soil fertility, in the Institute Federal Goiano– Campus, Morrinhos-GO, Brazil. The other, less soil fertility, was implanted in the ethanol industry Tijuco Valley, located in Rio do Peixe, district of Prata-MG, Brazil. The experimental design was randomized blocks in a factorial 5 x 2 +1 being five doses, with and without a biostimulant plus an additional with mineral fertilization, in four replications. The doses were in function of fertilization recommendation of planting and coverage for each environment, consisting of: 100 % of the mineral source and percentage 0; 60; 80; 100 and 120 % of organomineral fertilizer. We evaluated the productivity, tillering, diameter and height of stem in Prata-MG the different percentages of the fertilization of planting favored and increased productivity, height and stem diameter of sugar cane; the use of biostimulants not contributed to increase crop yield. In Morrinhos-GO, the different percentage of planting fertilization did not increase the productivity, tillering, height and diameter of the sugarcane stem; the use of biostimulants increases the productivity yield of sugarcane. Organomineral fertilizer based on biosolids is similar to fertilization with mineral fertilizer in environments.

<abstract> <p>The decrease in soil productivity and quality caused by the continuous and abusive use of mineral fertilizers makes necessary to adopt more sustainable agricultural soil management strategies that help to maintain soil edaphic fertility. In light of these considerations, we have evaluated the effect of organic vs. inorganic fertilization on soil microbial communities, soil quality, and crop yield in a melon crop. The following treatments were tested: i) aerobic sewage sludge from a conventional wastewater treatment plant (WWTP) using aerobic bacteria (SS); ii) aerobic sewage sludge from a WWTP using a bacteria-microalgae consortium (B); iii) N-P-K mineral fertilizer (M); iv) a treatment in which 50% of the N was contributed by SS and 50% by mineral fertilizer (M + SS); v) a treatment in which 50% of the N was contributed by B and 50% by mineral fertilizer (M + B); and vi) a no-fertilized control soil. Melon yield and fruit quality were determined in addition to several soil physical, chemical, biochemical and microbiological parameters. Organic fertilizers (SS and B) increased the percentage of soil water-stable aggregates (52 and 60% respectively) as well as the content of organic C (18 and 31%), water soluble C (21 and 41%), N (15 and 41%) and available P content (41 and 82%) compared to inorganic fertilization. They also stimulated bacterial and fungal abundance to a greater extent than mineral fertilizers (189 and 242% vs 85%, and 57 and 122% vs 29%, respectively), as well as soil respiration, and dehydrogenase, β-glucosidase, phosphatase, urease, and glycine aminopectidase activities. The analysis of principal components with parameters linked to soil quality clearly showed that organic fertilizers cause a greater improvement in soil characteristics and microbial community than mineral fertilizers. Results demonstrate that organic and combined fertilization could be used as substitutes for nitrogen mineral fertilizers in melon crop, since these treatments led to similar melon production and quality while improving soil characteristics and microbial population size and activity.</p> </abstract>
