AbstractThe solid fraction, according to many researches, is an effective organic fertilizer, the activity of which is at the level of mineral fertilizers and even exceeds their effectiveness, while the use of the liquid fraction does not always give positive results. In the article the optimal concentration of the liquid fraction in water solution for fertilization during cultivation of onion for chives in soil was determined. Sediment from biogas production was obtained at the thermophilic fermentation (50ºC) of cattle manure in the laboratory institution which operated at the periodical regime of loading. Fermentation lasted 25 days. Seven variants of plant feeding were assessed: clean water (control), mineral fertilizers (solution of ammonium nitrate in water in the concentration of 1:25), unsolved liquid biofuel fraction and mixture of liquid fraction from the postferment with water in concentrations of 1:10, 1:50, 1:100, 1:500. It was determined that the highest efficiency was observed in case of fertilization of plants with the mixture of liquid fraction from postferment with concentration of 1:500. Along with the increase of liquid fraction concentration and fertilization of plants with water solution of mineral fertilizers, onion productivity dropped slightly. Fertilization of plants with the liquid fraction from postferment resulted in fractional dying of plants and reduction of efficiency. The crop control of nitrogen content proved that in case of every day watering of onion with clean water and mixture of liquid fraction with water concentration of 1:100-1:500 did not exceed the maximum admissible concentration which is 800 mg·kg−1. Thus, in case of onion cultivation for chives, taking into consideration the crop growth and low nitrogen content, it is recommended to use the mixture of liquid fraction with water of 1:500 concentration.

Effects of fertilization with digestate from agricultural biogas plant and its influence on growth and selected physiological parameters of maize, triticale, and sorghum plants cultivated for biogas production were studied in this work. The digestate was used as an organic fertilizer, being a substitute or supplement to mineral fertilization. The fertilization with the digestate had a positive effect on the fresh matter yield (FMY) of sorghum (85.4 Mg ha-1), the dry matter content (DM) of maize (41.9%) and sorghum (23.6%), as well as on the dry matter yield (DMY) of triticale (12.2 Mg ha-1) and sorghum (19.8 Mg ha-1). Among the studied species, the maize fertilized with digestate (variants N2 and N3) showed better growth responses compared to the maize that was fertilized with mineral fertilizers (plant nutrition status – SPAD of 54.8). No significant influence of fertilization variant was observed on the photosynthetic active radiation (PAR) and the leaf area index (LAI) of the tested plant species. The digestate proved to be a good fertilizer, supporting high yields without adverse effects on the physiological parameters of the plants.

In order the intensive orchards bear fruit stably and give high yields every year, the mineral nutrition of fruit trees must be balanced with the help of fertilization. The soil fertilization plays an important role in this process, which provides the optimal content of essential mineral elements for fruit trees in optimal quantities. The soil nutritive regime and, accordingly, the yield of apple orchards in such conditions are significantly increased. The results of studies of soil nutritive regime and yield of apple trees of Calville snow variety on the seedling rootstock and Idared variety on the seedling and vegetative M4 rootstocks under re-cultivation on mineral nutrition backgrounds, created by long-term (over 86 years) application of different fertilizer systems on the dark-gray podzolized soil. Long-term systematic application of organic and mineral fertilizers and their combination provided the nitrate nitrogen content in the soil in the range of 26.2-28.6 mg/kg, mobile compounds and forms of phosphorus and potassium – 207-236 and 261-270 mg/kg of soil respectively, which exceeded the optimal levels of their quantity in the dark gray podzolized soil. Such changes in the apple trees supply with the main macronutrients, in particular against the background of systematic long-term application of organic and organic and mineral fertilizers, contributed to an increase in the total yield of experimental varieties by 17-35%. In the first period of growth and fruiting of young apple trees were mostly used for the formation of biomass of nitrogen vegetative organs for the plant fertilization, and in the period of full fruiting of potassium to create a fruit harvest. Increasing the Р2О5 content was ineffective. The higher efficiency of the organic fertilizer system was due to a greater increase in the mineral nitrogen content in the soil, and, especially, movable forms of potassium and a better improvement of physical and biological characteristics of soil fertility, as established by the studies of long-term use. It was found that under the organic fertilizer application the soil is enriched not only with N, P and K, but also with trace elements of mineral nutrition of plants

<p>Reducing greenhouse gas emissions, and in particular fossil carbon dioxide, is essential to sustain future human life on Earth. In this perspective, residual biomass becomes a potentially valuable resource to substitute fossil carbon, in particular when considered under the angle of national strategic planning. Yet, diverting this flow from its current (or baseline) use implies ensuring a net societal benefit, i.e. an overall enhanced environmental and economic performance. Here, we present an assessment covering the whole of France. The purpose of our study is three-fold: (i) providing and demonstrating a methodology for high-resolution spatial quantification of key residual biomass streams including Primary Forestry Residues (PFR), Agricultural Residues (crop residues, manure, prunings), Sewage Sludge, Garden Waste, Food waste (household, industrial); (ii) identifying the current use of these streams and (iii) quantifying, by life cycle assessment, the environmental impacts related to this baseline management. The vision is to supply the quantified minimal environmental performance that future bioeconomy uses of the residual biomasses must have in order to generate an overall improvement compared to today’s baseline. The aim is additionally to develop methods that can be reproduced and used for strategic circular- and bioeconomy planning in other countries (or regions) worldwide.</p><p>According to our results, the total biophysical available potential (in PJ y<sup>-1</sup>) is: PFR: 158 PJ y<sup>-1</sup> [83-261]; Crop residues: 1178 PJ y<sup>-1</sup> [988-1369]; Manure: 433 PJ y<sup>-1</sup> [345-520];  pruning residues: 57 PJ y<sup>-1</sup> [30-85]; garden waste: 61 PJ y<sup>-1</sup> [49-73];  household biowaste currently separately collected: 103 PJ y<sup>-1</sup> [83-124]; household biowaste not collected today: 89 PJ y<sup>-1</sup> [81-97]; agri-industrial biowaste: 81.4 PJ y<sup>-1</sup> [65-98]; sewage sludge: 15.2 PJ y<sup>-1</sup> [12-18]. This totals ~2100 PJ y<sup>-1</sup>, the equivalent of 20% of the primary energy supply in France. The current uses vary among the streams, including on-land decay, open-air burning, domestic heat use, direct use as organic fertilizer, use as organic fertilizer after composting or use as bedding, production of heat and power following biogas production through anaerobic digestion, mulch production and incineration amongst the most common ones. When services are supplied (e.g. heat, electricity, fertilizers), the life cycle assessment considered the avoided impacts induced by the substituted products (e.g. natural gas, mineral fertilizers).</p><p>To our knowledge, such a wide platform covering as many residual streams at this level of spatial resolution (from 10-m to the European NUTS-3 level), incorporating uncertainties and life cycle inventories on the current uses of streams, has never been elaborated until now.</p>

Biomass Resources

Energy plays an essential role in the modern society and can serve as one of the vital parameters of socio-economic development. Despite developments in technology, over three billion persons living in rural parts of the low- and middle-income countries continue to cover their energy needs for cooking through traditional ways by burning biomass resources. This paper as a case study focuses on the Aral Sea region of Uzbekistan, possessing a well-developed agricultural production with high livestock numbers and intensive crop production. The manure of the livestock farms is not used efficiently and the energy supply of the farms depends primarily on centrally produced gas and electricity. Some areas are not yet connected to the gas grid. Agriculture causes huge environmental damages in its current form. The benefit of biogas production would therefore be fivefold: (1) local energy source, (2) mitigation of environmental impacts, (3) reducing CH4-emissions, (4) producing organic fertilizer as a side product and (5) additional earnings for farmers.

Digestate is an anaerobic digestion by-product rich in inorganic-nitrogen (N) that can be used as an organic fertilizer. Digestate agronomic efficiency and its impact on the environment have not yet been studied in detail, therefore this study tries to fill this gap. The agro-environmental sustainability of digestate fractions was evaluated in a holistic way by comparing the best management practices available in the Veneto Region agroecosystem. A farm experiment involving mineral fertilizer and both liquid and solid digestate fractions was established involving silage winter wheat and silage maize as main crops. Agro-environmental sustainability was investigated coupling crop performance analysis (e.g., yield, N uptake and N use efficiency (NUE)) with a novel proposed agro-environmental sustainability index (AESI) (i.e., product of the dry yield and NUE). The results showed that the liquid digestate fraction gave agronomic performances comparable to mineral fertilizers and a satisfying AESI while solid digestate showed lower performances. In conclusion, liquid digestate fractions might be an effective substitute for mineral fertilizers in the Veneto region agroecosystem reaching encouraging levels of agro-environmental sustainability. On the contrary, longer-term experiments are requested to evaluate solid digestate fraction sustainability.

Digestate from biogas production can be recycled to the soil as conditioner/fertilizer improving the environmental sustainability of the energy supply chain. In a three-year maize-triticale rotation, we investigated the short-term effects of digestate on soil physical, chemical, and microbiological properties and evaluated its effectiveness in complementing the mineral fertilizers. Digestate soil treatments consisted of combined applications of the whole digestate and its mechanically separated solid fraction. Digestate increased soil total organic C, total N and K contents. Soil bulk density was not affected by treatments, while aggregate stability showed a transient improvement due to digestate treatments. A decrement of the transmission pores proportion and an increment of fissures was observed in digestate treated soils. Soil microbial community was only transiently affected by digestate treatments and no soil contamination from Clostridiaceae-related bacteria were observed. Digestate can significantly impair seed germination when applied at low dilution ratios. Crop yield under digestate treatment was similar to ordinary mineral-based fertilization. Overall, our experiment proved that the agronomic recycling of digestate from biogas production maintained a fair crop yield and soil quality. Digestate was confirmed as a valid resource for sustainable management of soil fertility under energy-crop farming, by combining a good attitude as a fertilizer with the ability to compensate for soil organic C loss.

Principal Possibility

An estimation of the possibility of dehydration of sludge-lignin of the Baikal Pulp and Paper Mill by the freeze-thaw method was carried out. Change of sludge-lignin structure, physicochemical properties and chemical composition after freeze-thaw are shown. Toxicity and chemical composition of the water solution separated from the sludge-lignin during its freeze-thaw is estimated. An increase in the rate of germination of seeds of the cress in the soil with the addition of the frozen-out sludge-lignin in the ratio "sludge-lignin-soil" 1:3-1:4 is shown. Possibility of application and recommendations for the use of freezed out sludge-lignin as an organic fertilizer is considered. Principal possibility of the worm transformation of sludge-lignin, previously dehydrated by the freeze-thaw method, by red Californian worms Eisenia foetida Andrei Bouche (1972) is shown. The issue of prospects for processing this waste in a fertile bio-soil is discussed. The latter can later be used for recultivation of the territory of the sludge accumulator plots of the Baikal Pulp and Paper Mill.

Abstract—Water is an important element that becomes the need of every human being, in the service provider company Clean water control of water usage is still a problem because there is no system that provides information on the use of water on the customer side, especially in the BLUD UPT SPAM Musi Rawas. Customers also find it difficult to see the amount of bills in realtime so that if the billing information has been presented then the customer can adjust the use of the water. This system will use a Waterflow Sensor to read the water flow which will then be converted to Digital data in the form of computer bits that will be processed by Arduino and then sent to the Server to be seen by the Clean Water Service Provider in this case the BLUD UPT SPAM Musi Rawas and customers. Intisari—Air merupakan unsur penting yang menjadi kebutuhan setiap manusia, pada perusahaan penyedia layanan Air bersih kontrol penggunaan air masih menjadi masalah karena belum ada sistem yang menyediakan informasi penggunaan Air pada sisi Pelanggan khususnya di BLUD UPT SPAM Kabupaten Musi Rawas. Pelanggan juga kesulitan untuk melihat jumlah tagihan secara realtime sehingga jika informasi tagihan tersebut sudah tersaji maka pelanggan dapat mengatur penggunaan Airnya. Sistem ini akan menggunakan Waterflow Sensor untuk membaca aliran air yang kemudian akan di konversikan ke data Digital  berupa bit komputer yang akan di proses oleh Arduino kemudian di kirimkan ke Server untuk dapat di lihat oleh Penyedia Jasa Air bersih dalam Hal ini BLUD UPT SPAM Kabupaten Musi Rawas dan Pelanggan.
