Bodenzoologische Untersuchungen auf den landwirtschaftlichen Boden- Dauerbeobachtungsflächen (BDF) in Bayern Regenwürmer als Bioindikatoren

In Bayern hat die Landwirtschaftsverwaltung auf 132 repräsentativen landwirtschaftlichen Flächen Boden-Dauerbeobachtungsflächen ausgewiesen. Für die bodenzoologischen Untersuchungen erwiesen sich Regenwürmer als gute Bioindikatoren. Bisher wurden 110 Acker- und 22 Wiesenflächen in zwei Durchgängen im Abstand von 5-7 Jahren untersucht. Die Individuendichte der Regenwürmer zeigt sowohl Bodeneigenschaften als auch die Intensität der Bewirtschaftung an.

Abstract: In Bavaria the agricultural administration has established long term monitoring sites on 132 representative farming areas. For soil zoological investigations earthworms proved to be an animal group with high indicator value. Up to the present 110 areas of arable land and 22 meadows have been investigated twice, within a period of 5-7 years. Earthworm density indicates soil properties as well as intensity of agricultural management.

Content of macroelements in Avena sativa L., Brassica napus var. oleifera and Lupinus luteus L. after contamination of soil by copper and zinc
© Aristotle University of Thessaloniki (6/2009)
The aim of the study was to determine the effect of copper and zinc contamination on macroelements content in plants. Research was located on two alkaline soils which in natural conditions were formed with loamy sand and sandy loam. The soil was contaminated with copper (Cu) and zinc (Zn) at the following rates: 0, 150 and 450 mg/kg of soil.

Comparison of the effect of heavy metals on the pedofauna of forest and meadow stands
© Aristotle University of Thessaloniki (6/2009)
In order to examine the soil contamination by heavy metals and to estimate its influence on the pedofauna, two forest stands and two meadow stands (located in the vicinity of woody areas) have been chosen. The content of Cd, Ni, Pb, Cu, and Zn in the soil of the stands was investigated using an atomic absorption spectrophotometer. Some environmental parameters were also analyzed, such as temperature, humidity and soil pH. The soil samples were neutral or slightly alkaline. The content of all heavy metals was smaller in the soil of the forest park. Cd and Pb content in the meadow and forest soil of the protected landscape park was high. It was found that in the forest park the density of pedofauna was higher than in the meadow and forest of the protected landscape park.

The influence of soil – plant factors on the uptake of Cs by two plant species
© Aristotle University of Thessaloniki (6/2009)
To investigate Cs uptake by two different plant species grown on soils with contrasting physicochemical properties, a greenhouse pot experiment was conducted. Soil in each pot contaminated with 40 ug g-1 of Cs in the form of CsCl by spraying the solution in layers. After an equilibration period of two months, the soil of each pot appropriately sowed with seeds of Lolium perenne and Trifolium pratense plants.

Land degradation due to diapirs in Iran, case study: Hableh-Rood Drainage Basin, East of Tehran
© Aristotle University of Thessaloniki (6/2009)
Different geological characteristics play role in land degradation in Iran which are: 1-The abundance of Neogene evaporitic marly formations around and in desertic depression. These units have had important role in the formation of present landforms, are saline, alkaline and erodible and degrade the quality of water resources as diffuse and widespread sources. 2- The presence of numerous diapirs, some of which are salt domes consisting of halite.

Using topography and vegetation attributes for estimation of saturated hydraulic conductivity in semiarid rangelands of Iran
© Aristotle University of Thessaloniki (6/2009)
Topographic (elevation, slope, and aspect) and vegetation attributes are routinely available data from digital elevation models (DEMs) and normalized difference vegetation index (NDVI). The objective of this study was to use topographic and vegetation attributes in addition to soil attributes to develop pedotransfer functions (PTFs) for estimating soil saturated hydraulic conductivity (Ks) in the semiarid rangelands of Iran.
