Magnetic mapping of distribution of wood ash used for fertilization of forest soil.

The effect of wood-ash fertilization on forest soils has been assessed mainly through geochemical methods (e.g., content of soil organic matter or nutrients).

Application of magnetic methods for assessment of soil restoration in the vicinity of metallurgical copper-processing plant in Bulgaria.

Copper ore mining and processing are among the most harmful anthropogenic influences for the environment and they are a subject of international and national law regulations. Recultivation of areas influenced by mining and processing industry is commonly applied and monitored in order to restore as much as possible the natural environment. In this study, environmental magnetic methods are applied in order to assess the degree of soil restoration in terms of soil development, after remediation of waste dump from Cu-processing plant.

Magnetic anomalies of forest soils in the Upper Silesia-Northern Moravia region.

Previous investigations revealed a strong magnetic anomaly due to soil magnetic enhancement in the industrialized cross-border area of Upper Silesia (Poland) and Northern Moravia (Czech Republic). Since industrial and urban dusts contain magnetic particles, this soil magnetic enhancement is assumed to be of anthropogenic origin, caused by a high concentration of atmospherically deposited magnetic particles, accumulated in topsoil layers. This assumption is proved by investigations of vertical profiles of magnetic susceptibility along a transect crossing the border area of the two countries.

A new tool for in situ measurements of the vertical distribution of magnetic susceptibility in soils as basis for mapping deposited dust.

In situ measurements of magnetic susceptibility of topsoils are commonly used for mapping the spatial distribution of atmospherically deposited ferrimagnetic particles. However, the surface measurements integrate signal from certain soil volume and, thus, it is not evident how deep is the magnetically enhanced layer, if there is such. This information is often required for detailed sampling.
