Opis:: Streszczenie w języku polskim
Strony 313-326 : ilustracje ; 24 cm
The influence of high doses of NPK fertilizers has been examined as regards the density of spiders, size of individuals, degree of penetration of the area and changes in the pattern of dominant species. Changes occurring immediately after first fertilization have been taken into consideration and also tendencies over the 8 years of fertilizing. Intensive fertilization results in changes in the dominance structure. Large, mobile species (Lycosidae) are replaced by smaller, sedentary ones (Linyphiidae). In the course of years the differences between fertilized and not fertilized plots are becoming less distinct.

Opis:: The article discusses the issue of the departure from examining real behaviours in a real environment, a trend in social psychology which has been observed going back several years, and the impact of this phenomenon for social psychology as a scientific discipline. The article presents two studies on the well-known and explored “bystander effect” (Darley, Latane, 1968). This phenomenon is examined in two ways – once by way of a “traditional” field experiment conducted in natural conditions, and once through a survey. As it turned out, the results generated by the two studies were diametrically opposite, and only in the field experiment were we able to achieve a pattern of results consistent with those in the original studies.

Opis:: Application of a field experiment in soil erosion research in the Chwalimski Potok catchment (Drawskie Lakeland, upper Parsęta River)Stationary research upon soil erosion has been conducted in the Chwalimski Potok catchment since 2012 as a continuation of research started in 1994. In 2013 conducted two field experiments were conducted in order to evaluate the impact of high intensity rainfall on soil surface. The first experiment consisted of 5 and the second of 4 rainfall simulations. The rainfall was created by using a purpose-built rain simulator, consisting of 3 and 6 sprinklers placed around the testing plot. The paper focuses on the characterization of the course of these experiments. The achieved results compared with the results from the hydrological years 2012 and 2013 show that slope wash considerably increases during rainfall of high intensity and high amount.

Opis:: The study characterized the regime of nutrient leaching under different nitrogen and phosphorus supply of irrigated maize grown as monoculture on Fluvisol for the period 1999-2008 and additionally studied in the years 2009, 2010, and 2011. The aim of the study was to estimate the effect of long-term fertilizer application on the leaching of nutrients from the soil under maize grown as monoculture. The experiment design included four nitrogen fertilizer rates (B1-control, B5, B4, B3, B2) calculated to compensate 50, 75, 100, and 125% from the plant N uptake, respectively. The field plots were equipped with lysimeters (at 50 and 100 cm depth) for studying the relationship between the applied fertilizer rates and the nutrient concentrations in the lysimetric water. The greatest nitrogen concentration in lysimetric water was observed under variant (B3-N200 P150) throughout the study period and the highest N losses were registered (36 kg ha-1) in 2010 under the same treatment (B3). A very good correlation was found between the N rates, calcium, and magnesium losses. Lysimetric water component compensation shows that agricultural activities have only influenced the speed of weathering and had no significant effect on the rates.

Opis:: Aims The uncontrolled spread of invasive plant species is a major driver of biodiversity loss in plant communities. We evaluated a recently proposed biological method for invasive plant control, based on the application of a bioherbicide containing L-arginine developed by White et al., Rutgers University, USA. This approach exploits the ability of microorganisms to synthesize ethylene from arginine supplied by plants, which, at high concentrations, induces excessive production of reactive oxygen species (ROS), leading to plant death while leaving no chemical residues in the treated soil. Methods The bioherbicide was tested for its ability to control Solidago canadensis colonizing areas in Krakow, Poland. To enhance the effectiveness of the bioherbicide, endophytic microbes were isolated from S. canadensis, molecularly identified, and multiplied. The influence of the bioherbicide on both above- and below-ground plant organs in the presence of endophytes was examined under field conditions. Photosynthetic efficiency and mycorrhizal diversity were assessed before and after application of the bioherbicide. Results Molecular analysis revealed most of fungal endophytes isolated from S. canadensis as members of Ascomycota. The best-performing strains were used within the bioherbicide. One year after the bioherbicide use, S. canadensis exhibited reduced photosynthetic performance, rhizome degradation, and a significant decline in shoot number, including generative shoots. Mycorrhizal colonization of remaining plants from treated plots remained unaffected. Conclusions These findings highlight the potential of L-arginine-based bioherbicides as an environmentally safe alternative to chemical herbicides for invasive plant management, particularly under conditions of climate change and ongoing species introductions.

Opis:: A tillage system can affect significantly the concentration of some heavy metals and their availability to plants which grow on the tilled soil. The purpose of this study has been to determine the impact of different tillage systems on the chemical properties of arable sandy loam soils under the same crop rotation, organic residue management and mineral fertilization. A single-treatment field experiment in a randomised block design was performed on sandy loam soils. Four-year tillage study data were compiled and compared with respect to full-inversion tillage (FIT), strip-till (ST) and reduced tillage (RT) systems. Soil samples were mineralised in a mixture of HF and HClO4 acids to determine the total content of metals. Total organic carbon (TOC) and total nitrogen (Nt) were also assayed. The content of available metal forms was determined using diethylene triamine pentaacetic acid (DTPA). The soil maintained in the FIT system contained significantly more Zn and Fe available to plants than the soil cultivated according to the RT and ST systems. The FIT and ST systems decreased the total Zn, Cu, Mn and Fe content in soil significantly compared with the RT system. Relative accumulation of the heavy metals at the depth of 30-50 cm can be related to the distribution of the clay fraction in soil profiles. In the topsoil (0-30 cm), the average content of TOC was significantly higher under the RT than under FIT and ST systems. The results confirm that a tillage system is one of the factors affecting the content of heavy metals, TOC accumulation and heavy metal distribution in sandy loam soils, although the pedogenic processes determining the quality of arable soils quality must be considered as well.

Opis:: Based on a three-year field experiment under controlled condition in Ji’nan, China, the effects of peanut growth on the variation in the abundance and community structure of ammonia oxidizing bacteria (AOB) and archaea (AOA) before and after peanut growth were investigated through quantitative PCR and cluster analysis of terminal-restriction fragment length polymorphism. Our results show that the community composition of AOA and AOB was greatly affected by the peanut growth leading to the decreased abundance of AOA and increased abundance of AOB. Furthermore, AOA and AOB community structures varied before and after peanut growth. Phylogenetic analysis indicated that all AOA and AOB community sequences were clustered into the uncultured group. Altogether, the results suggested that the abundance of AOA and AOB in soil and their community compositions can be greatly affected by the peanut growth.

Opis:: Soil erosion by water is influenced by a major morphogenetic factor – precipitation. Surface runoff, initiated by rainfall, plays a key role in this process. This article addresses the effects of rainfall intensity and soil moisture on soil erosion through a series of rainfall simulations of different intensity and duration. The implementation of measurements at a research station located in the Różany Stream catchment in Poznań made it possible to study the entire water balance within the slope, including precipitation, evaporation, surface runoff and infiltration. The study included various rainfall intensities, with a focus on extreme events reflecting ongoing climate change and increasing anthropopressure. Rainfall simulations were conducted on both dry and wet ground. The results showed that increasing rainfall intensity led to greater surface runoff and soil loss. Moreover, soil moisture was identified as a critical factor affecting soil erosion, with wetter conditions reducing soil loss while increasing surface runoff.
