This paper presents the introductory considerations for soil monitoring to be established in the forested zone of the Karkonosze National Park. The strategy and techniques of soil sampling are discussed with reference to the variability of soil properties. Based on the examples of 12 monitoring areas and the detailed analysis made for 5 of them, it was found that particularly high spatial differentiation...
The studies were carried out within a catena of loess soils of the West Roztocze region. These are typical grey-brown podzolic soils (Haplic Luvisols) in various stages of erosion and deluvial soil (Eutric Fluvisol). Research shows the great variation in the morphology and the physical-chemical properties of the soils. Differences observed included the content of humus, range of soil reaction, depth...
The environmental study, carried out in the Lublin region, was aimed at assessment of strawberry fruit quality based on the contents of heavy metals (Pb, Cd, Ni, Zn, Cu, As, Hg) and finding correlation between these heavy metals and some properties of soil and plant. Heavy metals in soil and fruits were determined with ASA method, other analyses according to research procedures of the laboratory of...
The presented studies show the important role of slope covers, which often differ in their properties from the underlying bedrock, and in the formation of the studied soil profiles and the occurrence of discontinuities within the parent soil material. The observed regularities affect the analysed physical properties, particularly as regards the amount of retention and filtration in the genetic horizons...
The aim of the study was to estimate some of the microelements (Cu, Zn, Mn, Pb and Cd) in the form available to plants and extracted from the soils of the Bellsund seaboard with DTPA-TEA and to estimate the level of connection between these metals and the soil properties. The study of the microelements was conducted during the polar expeditions of the Institute of Earth Sciences (UMCS, Lublin) to...
This paper presents the results of a long-term study on trace elements content in the ectohumus horizons (O) and the mineral horizons (A or A/B) of the Puszcza Kampinoska Biosphere Reserve soils. Studied were the trace elements: Mn, Pb, Zn, Cu, Ni, Cr, Co. It was found that the mineral horizons of the soils contain natural amounts of the heavy metals; an increased concentration of Pb, Zn and Cu was...
This paper presents the results of studies on cretaceous rendzinas overgrown by the communities that are consecutive stages of xerothermal sward successions. The studies were carried out in the Stawska Góra Nature Reserve close to Chełm. The aim was to trace the directions of the changes in soils physical and chemical properties in the relation to the transformations in the xerothermal phytocenoses...
For sustainable soil use soil quality is essential presumption. Soil quality does not depend only on the physical and chemical properties of soil but it is very closely linked with the biological properties of soil mostly on microbiological processes. Soil quality is a dynamic feature, and any significant indicators must be sensitive to small changes in key soil properties. During the years 1991-2002...
In the year 2000 the occurrence of Azotobacter spp. in 31 Polish soils was examined and results of this study were compared with those published by Ziemięcka for 28 soils analysed in 1917-18. Almost 52% of the soils tested in 2000 were colonised by Azotobacter spp. indicating that intensification of agricultural practices that took place during the past century has not significantly changed (50% soils...
Studies were carried out in a 8 years old shelterbelt planted across croplands (D. Chłapowski Landscape Park, region of Wielkopolska, western Poland) and in the easterly adjacent field. The effect of the shelterbelt on: soil organic matter content, soil respiration, microbial biomass, dehydrogenase activity, mineralization potential of N and total number of bacteria and fungi in the upper soil layer...
In a laboratory experiment, the changes of extracted phosphorus (DEP) in 33 limed and non-limed soils were determined 7 and 30 days after fertilisation with P, as well as DEP and DEPCa indices were evaluated as related to P sorption and to certain soil properties. The concentration of available phosphorus in the soils was measured in 0.03 M CH3COOH extract by the Nowosielski method. The changes of...
