Our paper presents results of nutrient removal from household wastewater in the bioreactors with nonwoven filters. The experimental system was constructed from two groups of bioreactors in laboratory scale with gravity-fed wastewater supply. The variable differentiating the work of both tested systems was the method of sewage dosing. In both experimental groups, there was a statistically significant...
The study aimed to evaluate the yield and economic effectiveness of spring barley grown in crop rotation and cereal monoculture under three tillage systems. The experimental factors were crop sequence systems: 1) crop rotation (peas – spring barley – winter wheat) and 2) cereal monoculture (spring barley – winter wheat – winter wheat) and tillage systems: a) conventional tillage (CT), b) reduced tillage...
The aim of this study was risk assessment regarding the local scours below sills that stabilize the Warta riverbed below Jeziorsko Reservoir. The studied river sills were constructed due to the reduction of riverbed erosion that took place downstream behind the dam reservoir. The research area embraced two reaches: in the vicinity, sills No. 3 (km 480+902) and No. 4 (km 479+225) were built in order...
The aim of the present study was to evaluate yield, grain quality characteristics, and cost-effectiveness of different crop protection methods in the cultivation of spring wheat using two levels of mineral fertilization of crops. The study shows that the combined application of the herbicide Lintur 70 WG (dicamba and triasulfuron) with ethephon or chlormequat chloride did not adversely affect spring...
The aim of our study was to evaluate the effects of nitrogen (N) and sulphur (S) fertilizer on harvest index (HI), agronomic efficiency (AE), physiological efficiency (PE), utilization (U), and final efficiency index (EFI). We conducted a field experiment (2009-11) in southeastern Poland on Cambisols (WRB 2014). The experiment included two variables: N fertilization (0, 40, 80, and 120 kg/ha) and...
With the adoption of the Water Framework Directive, monitoring of surface waters has undergone a reform process. It introduced a new approach to the assessment of surface waters based on biological elements. In the case of water reservoirs, the monitoring is based on phytoplankton, phytobenthos, and macrozoobenthos, as well as chlorophyll concentrations. The ecological evaluation is supported by physicalchemical...
The results of recent studies indicate that obesity is associated with an increase in peroxidation processes. The aim of the present study was to assess the degree of oxidative stress in obese women and to evaluate the relationship between selected markers of oxidative stress and body mass index. Study population consisted of 43 women aged 21 to 66. Subjects were divided into two groups according...
The presented work shows a method of evaluating the changes of territorial sozofloristic value which illustrates the effects of anthropogenic pressure on threatened and rare flora of a given area. As a result, a distribution map of the changes of the flora is shown, aiming to support conservation activities within Opole voivodship, e.g. the flora conservation strategy. The territorial sozofloristic...
