They can play a significant role in fixing atmospheric nitrogen and production of plant growth promoting substances. Therefore, in the development and implementation of sustainable agriculture techniques, biofertilization has great importance in alleviating environmental pollution and deterioration of nature. In order to study the effects of mineral nitrogen fertilization and biofertilizer inoculation on grain yield and its components of rapeseed ( Brassica napus L.) under different levels of sulfur fertilizer, a field experiment in Factorial scheme based on Randomized Complete Block design was conducted in three replications. Experimental factors were as follows: (i) Four levels of chemical nitrogen fertilizer (0, 100, 150 and 200 kg N ha –1 ), (ii) Two levels of biofertilizer (with and without inoculation) containing Azotobacter sp. and Azospirillum sp. and (iii) Two levels of sulfur application (0 and 50 kg S ha –1 ). Rapeseed yield and yield components had a strong association with the N fertilization, biofertilizer inoculation and S application. Higher rates of N fertilization, biofertilizer inoculation and S application increased plant height, pods number plant –1 , grains number pod –1 , 1000-grains weight, grain yield and biological yield. It seems that moderate N rate (about 150 kg N ha –1 ) and S application (about 50 kg S ha –1 ) can be beneficial to improve growth, development and total yield of inoculated rapeseed plants. So, it is suggested to use a combination of organic and inorganic fertilizer to achieve the highest yield without a negative effect on grain quality that will lead to sustainable environment.","PeriodicalId":35175,"journal":{"name":"Socijalna Ekologija","volume":"236 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79703885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biogas from anaerobic digestion process is one of the most perspective alternative energy sources.\u0000 Directive EU for renewable energy targets has been determined to 25% in 2020 for Estonia. Presently (2010) in Estonia the share of renewable energy rose to approximately 21%.\u0000 The annual of municipal solids waste (MSW) generated in Estonia accounts for 0.5 million tons or, taking into account the urban population (1.344 million inhabitants), 372 kg per capita. Up to 56% of total municipal solids waste generated in Estonia is easily biodegradable and can be used for biogas production.\u0000 The volumes and qualities of different types of biodegradable fraction of municipal waste, industrial waste and waste of landscaping, agricultural waste and sewage sludge generated in Estonia during the period from 2002 to 2011 were analysed and their energy potential was estimated.\u0000 The obtained data demonstrates that the main sources for biogas production are sewage sludge and animal manure. Also wastes of food industry, biodegradable municipal waste, and herbaceous biomass and agriculture products may be used. Special attention is paid to agricultural products and waste.\u0000 The minimum energy potential from waste in Estonia may be estimated as 306.69 GWh per year, but this is only 3% from total energy production in Estonia. For the achievement of the recommended level of using renewable energy in Estonia in 2020, other natural sources of energy such as solar, wind, rain, etc. will be used.","PeriodicalId":35175,"journal":{"name":"Socijalna Ekologija","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76445117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic process was investigated using filters packed with these materials. The third material analysed, synthetic sorbent Fibroil, was chosen for comparing the results. The laboratory experiments were performed in two stages, with the following being filtrated: tap water with a diesel admixture, road runoff contaminated with PP, and also suspended solids. The significance of this work is due to high runoff filtering rate (~10 m/h) and high PP concentrations in the runoff (>50 mg/L) used in the experiment. In these cases the use of sorbents is limited. Schoenoplectus lacustris and Typha angustifolia fillers are quite efficient (92–98%) in PP removal from runoff at a 10 m/h filtering rate. Use of them for filtration was possible longer than Fibroil, it clogs up quickly. Schoenoplectus lacustris and Typha angustifolia are a natural source for the production of PP sorbents. The results obtained in this experimental work can be used in the design of equipment for the treatment of PP contaminated runoff.","PeriodicalId":35175,"journal":{"name":"Socijalna Ekologija","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88203705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the pristine river roach fed on various taxa of macroinvertebrates and plant material with similar frequency, none of food categories clearly dominated in the guts of fish. The overall diversity of food items in the diet as well as abundance and diversity of macroinvertebrates in the benthic assemblages were the greatest in the moderately polluted river, but plant material formed the major part of food and was consumed most frequently, presumably as a result of inter-specific competition for the food resources. Percentage of the plant material in the diet was the smallest in the heavily polluted river, where roach predominated over the rest of fish. The growth rates of roach did not differ among reference and heavily polluted river, but in the moderately polluted river fish grew much slower. It is likely that habitat degradation to an extent when majority of less tolerant fish and macroinvertebrate species do not survive seems to be favorable for roach, if the degradation reduces inter-specific competition for food resources.","PeriodicalId":35175,"journal":{"name":"Socijalna Ekologija","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86365617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
