The main subject of the paper is the spatial and temporal variability of biometeorological conditions in the north-western part of Poland during the period from 1951 to 2015. Bioclimate constitutes an important element of human life. Extreme phenomena are of importance. The occurrence of unfavourable biometeorological conditions according to Apparent Temperature (AT) was analysed. AT is expressed as the temperature which, under reference humidity conditions, determined by the dew point temperature equal to 14?, pr...

The Arctic coastal zone is very sensitive to environmental changes and anthropogenic impacts. The western part of the Russian Arctic is well studied because there is a lot of petroleum-gas deposit mines, especially on the Yamal peninsula, however data about the soil properties of the coastal zone does not appear much in the published literature. This is because people who investigated in the coastal dynamics do not study the soil properties, and vice versa, those working in the geoengineering survey do not publish...

For reasoned reconstruction of initial presence of various organic substrates in the soil-ground material of archaeological sites, a model experiment was performed, where the dynamics of decomposition of organic substrates of protein, lipid and polysaccharide composition by soil microbial communities was studied. The experiment was carried out on gray forest soil under optimal conditions (60% WHC, 25oC). Soil samples were enriched by one of the substrates of protein (gelatin, casein, and sheep wool), lipid (sheep ...

The researches have emphasized that on the improved sandy soils the maize yields (the average of fertilizer rates) is higher when the corn is cropped within a crop rotation than in monoculture (table 1, figure 1). The applying of nitrogen fertilizers on improved sandy soil, along with phosphorus ones is an endorsed measure for increasing maize yield (table 2, figure 2). The influence of crop rotation and fertilizer applying has recorded high yield outputs with all experimented crop rotations as compared with the m...

The article analyzes the thermal and humidity conditions of the ?arnowska Peatland, which is part of a larger complex of raised bogs located in the coastal zone of the Baltic Sea in Poland. The research was carried out on the basis of long-term changes in air temperature, atmospheric precipitation and field evaporation (1951-2015) from the synoptic station in ?eba. The mentioned indicators were used to determine their impact on the formation of seasonal variability of groundwater level on the peat bog. The climati...

A geographical location, an atmospheric circulation, a terrain sculpture and the presence of water reservoirs determine thermal conditions in Poland. The influence of these factors overlaps an impact of local factors as well as the effects of air transformation as a result of the process of an energy exchange at the interface between the atmosphere and its surface. The thermal conditions prevailing in a specific area can be determined on the basis of average values and extreme air temperatures. These characteristi...
