In this paper soil-climatical conditions in selected localities in Namysłów commune has been analyzed. The soil and climate conditions has been analyzed with regard to agricultural utilization of wastewater for energy plants irrigation. Using available literature the possibility of wastewater management coming from villages: Brzozowiec, Mikowice, Ligota Ksiażecą, Przeczów was indicated. In the paper there were presented the proposed solution benefits and attention was paid to the existing technical infrastructure and its possible expansion. ...
The paper presents the possibilities of growing energetistic plants and its ecological and economic effects anticipated. Emphasized is the potential contained in infrastructure of Polish countryside, i.e. unutilized farm buildings, areas out of agricul¬tural production, unma-naged side-crops and free manpower. Listed are plants to be designed for energetistic purpos-es and and ways of their utilization. Potential advantages of using liquid wastes for irrigation of the energetistic plants, as well as impediments involved, have been pointed to. The ways of the countryside deve¬lopment described call for engagement of local self-government communities and adequate financial means ...
The paper analyses results of measurements of precipitation amounts in the Widawa River basin in the multi-year period 1956-2012. Analysed were annual, monthly and daily precipitation totals and the numbers of days with precipitation in a year and in a month. Trends of changes were determined and extreme monthly and daily precipitation totals were analysed. Annual precipitation totals over the analysed multi-year period were very strongly diversified. Despite a considerable spread of results, the distribution in time did not reveal any clear tendency of changes, the trend line was almost horizontal. The number of days in a year with precipitation revealed an obvious decreasing trend, particularly within the fraction of days with precipitation <1mm. Average daily precipitation obtained from the ratio of annual precipitation total and the number of days with precipitation showed a growing tendency. December was the month in which the highest number of days with precipitation was noted during the multi-year period 1956-2012. Considering the fewest number of days with precipitation, similar results were obtained for three months. In May and September the least number of days with precipitation was registered eleven times. Only once a less often mentioned number of days occurred in October. A summary ...
Results of air temperature measurements in the 1957-2014 multi-annual period were analysed in the paper. The data originated from Jelcz-Laskowice locality situated in the south-western part of Poland, at the flat part of the Lower Silesia, on Silesian Lowlands. Average annual and monthly air temperatures and the number of days of thermal seasons duration were analysed. Trends of changes were set and extreme values of average monthly air temperatures were analysed. Mean annual air temperatures in the studied multi-annual period revealed a tendency to increase. Average monthly extreme values of the analysed factor revealed a similar direction of changes; however, more apparent changes occurred for the maximum values. Over the analysed period, average monthly air temperatures revealed a tendency to increase. The most serious changes occurred in July, slightly lesser in August, May and April. The number of days in the years 1957-2014 in the interval limited by the air temperature threshold values: 0oC, 5oC and 15oC was greatly diversified. Analysed results had a clear growing tendency for the summer, slightly lower for the spring, but evidently declining for the autumn. ...
