The aim of study was to estimate survival, the rate and range of migration of fecal bacteria in soils fertilized with bovine slurry. The research showed that a great majority of fecal bacteria was retained in higher parts of soil profiles. The precipitation, physical and chemical properties of soil, the bacterial population density used in experiment were most important factors that influenced infiltration...
The research was carried out on farms of the Bory Tucholskie Landscape Park near Tuchola. The aim of the research was to define the quantitative content of bacteria of Pseudomonas (the fluorescent subgroup), Arthrobacter, Azotobacter and the coryneform group in the rhizosphere of potato in different stages of its development. The Aster potato was grown in two farming systems: ecological and conventional...
Slurry often contains many pathogenic microorganisms, which are dangerous to human and animal health. The aim of study was to estimate the elimination rate of indicators and pathogenic bacteria Escherichia coli, fecal streptococci D-group and Salmonella senftenberg W775 in peat soil according to soil storage temperature and slurry addition. The elimination rate of fecal bacteria was more effective...
The sewage treatment plant was monitored to determine the efficiency of technologies employed to reduce microbiological threats. Every four weeks, for a year, sewage was sampled to investigate the effects of post-mechanical and post-biological treatment. Changes in Escherichia coli, D-group streptococci and Salmonella spp. number were analyzed. The reduction of the bacteria in sewage treated mechanically...
Four pedons of Alfisols were selected from the Experimental Station Mochełek to study chemical composition of the soil material. The study area is located in the south-western border of the Krajeńska Upland, on the border of two geomorphological formations: erosion surface of floating waters (fluviglacial formation) and rolling ground moraine (glacial material). The investigated soils were classified...
