Due to it, the amount of waste from the chicken industry is also increasing. Therefore, more efficient conversion of chicken manure to organic fertilizer is key problem all over the world. Therefore, the aims of present study are to investigate the changes in temperature and moisture content during composting of chicken manure in a tank fermentation system and create a model to describe the biodegradation processes. In this study, Hydrus software was used for modelling the moisture and temperature distribution in the oval tank during the decomposing processes. It was found that the studied oval tank fermenter can be divided into two main parts considering to the changing of temperature and moisture level. In the first phase after the intake – where the rate of biodegradation is high there is a heterogeneous temperature zone with decreasing moisture content. Moreover, in this stage a special temperature profile was found at the crosssectional view of the tank. The second phase was more homogenous both in temperature and moisture content. This stage is the weak fermentation part of the technology results an elongated post fermentation section. It was established, that the changes of temperature and moisture content along the tank fermenter are the same and there is a strong connection between them in the examined period. Our results pointed out that the initial turning and mixing results in a large temperature and moisture content drop and later there is sufficient time for composting to take place. The authors recommend that this system could be used as an efficient treatment for chicken manure materials to decompose and get a valuable base organic fertilizer.","PeriodicalId":33009,"journal":{"name":"Natural Resources and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69794862","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}

This study was conducted to assess vegetation dynamics in three CREMAs in the northern savanna zone of Ghana through the application of remote sensing techniques and field observation. The findings showed the vegetation cover of all the three study areas improved over the period between 1990 and 2010. There were indications of successions from lower tier vegetation classes to higher ones. The riparian vegetation of the study sites changed from open savanna woodland to closed savanna woodland mainly through the grazing activities of the hippopotamus (Hippopotamus amphibious) and management practices that restrict farming, livestock grazing, charcoal production and suppress wildfires. The suppression of wildfires has resulted in considerable amount of fuel load which must be managed to prevent severe-intensive-fires in the future. Notwithstanding the general improvement in vegetation cover, there were also considerable increased coverage of bare surface/built up areas indicating economic activities also moved up over the period.","PeriodicalId":33009,"journal":{"name":"Natural Resources and Sustainable Development","volume":"377 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69794038","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}

A forest site is characterized by forest biomass, which is determined by elevation characteristics, soil type and climate. Height of tree is widely used parameter for terroir typifying, but measuring of tree height is sometimes timeand labour-consuming and could affected by errors. Airborne LiDAR technology is an effective tool for determine fast and accurate the tree height on relative larger area. GIS software environment provides to prepare the high resolution digital elevation model (DEM) and digital surface model (DSM) for pixel-based canopy height. Traditionally, the operational tree height estimation can significant differ from the actual tree heights. In our investigation, between the LiDAR-based elevation parcel map and operational tree height estimation, a close correlation (r=0.7935) was detected. The aim of our research was creating a site qualification map, based on airborne LiDAR data. Tree height map was completed with soil type data. Trees are different age on the plot area, so age-based standardization was carried out by modified Chapman-Richards growth function to examine the increments of trees. In order to evaluate the forest site quality, created increment map was categorized. Based on the results, surface hydrology features are mainly influenced the tree increment, so the dendromass. Nevertheless, significant differences were observed between the tree increments in different soil types; higher salt content resulted smaller (62.49%) trees in Solonetz soil.","PeriodicalId":33009,"journal":{"name":"Natural Resources and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69793589","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}

Present study focuses on the thermal water utilisation possibilities i.e. energy content utilisation, balneological utilisation, irrigation, and the related environmental aspects in North East part of Hungary. Among the environmental effects the total dissolved solid concentration and the methane and carbon dioxide content are examined through the examples of 66 thermal water wells screened into pannonian sensu lato (s.l). succession. Thermal water utilisation may have many various environmental aspects: chemical impacts, gas emission, thermal effects, water quality effects noise effects, landscape change, from which methane and solids dissolved in thermal water emitted by its extraction are highlighted. Considering that the annual thermal water extraction from reservoirs located in the Northern part of the Great Hungarian Plain the annual Total dissolved solid concentration (TDS) and methane production can be estimated as 28,207 tones and 1,671,482 m 3 , respectively. It must be highlighted that by applying cascade systems, the efficiency of thermal water utilisation can be improved while environmental aspects do not increase considerably.","PeriodicalId":33009,"journal":{"name":"Natural Resources and Sustainable Development","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69793663","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}

Then based on the spectral data, principal component analysis was performed to select the appropriate wavelength ranges. In the case of maize, the Natur extra and Nitro-plusz poultry manure pellets produced outstanding results on sandy soil and we can raise. In the case of wheat, the P+K manure pellets produced outstanding results. The absorption of chlorophyll can be measured at 678 nm and chlorophyll b at 650 nm. When we carried out the principal componenet analysis, we could select the 520-650 nm wavelength range and 700 nm wavelength for maize. For wheat the wavelengths were 540-650 nm and 702 nm.

The most precision animal husbandry innovations are in the precision breeding and nutrition, but nowadays, different robots (e.g. robotic milking systems, robotic barn cleaners, etc.) can help for effective animal production, mainly in barn. The number of such innovative solutions in field is less. In order to collect spatial information about the ethology of animals, grazing dairy cattle are survey by LiDAR sensor. The focus area is a pasture near Nyírbátor (BÁTORTRADE Trade and Services Ltd., North Trans Tisza Region, Hungary). Application of LiDAR terrain characteristic, topography, vegetation status (e.g. the qualitative and quantitative characteristic of vegetation) and grazing cattle in the pasture can be detected. The main goal of our study was to detect grazing cattle on field by ALS system. LiDAR data was useful for animal detection, and based on the spatial data lying and standing animals were identified distinguishing from each other. In order to examine the statically position of cattle, digital elevation model was created based on the high precision spatial data. Based on the distribution and behaviour of the animals, different problems (e.g. environmental stress) in animal husbandry could be concluded. Multispectral image pattern and monitoring the spatial distribution of cattle’s movement, wet locations can be identified on the pasture. Using LiDAR data seems a promising opportunity to optimize land use and livestock size.","PeriodicalId":33009,"journal":{"name":"Natural Resources and Sustainable Development","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69793971","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}
