“…The Saale-Elbe region is known for its former coal mining industry (Eissmann, 2002), and anthropogenicallyinfluenced groundwater has the lowest 87 Sr/ 86 Sr ratios in the Bitterfeld/Wolfen mining area (Petelet-Giraud et al, 2007), located 70 km away from our study area. Moreover, forests have been frequently limed in Germany, and especially during the 1980s (Huettl and Zoettl, 1993). The liming of forests can readily account for the decreasing trend in 87 Sr/ 86 Sr observed in a tree core (Drouet et al, 2005a) when the 87 Sr/ 86 Sr ratio of the underlying geological substrate is higher than that of the lime.…”

Sr/ 86 Sr reference maps (isoscapes) are a key tool for investigating past human and animal migrations. However, there is little understanding of which biosphere samples are best proxies for local bioavailable Sr when dealing with movements of past populations. In this study, biological and geological samples (ground vegetation, tree leaves, rock leachates, water, soil extracts, as well as modern and archeological animal teeth and snail shells) were collected in the vicinity of two early medieval cemeteries ("Thuringians", 5-6th century AD) in central Germany, in order to characterize 87 Sr/ 86 Sr of the local biosphere. Animal tooth enamel is not appropriate in this specific context to provide a reliable 87 Sr/ 86 Sr baseline for investigating past human migration. Archeological faunal teeth data (pig, sheep/goat, and cattle) indicates a different feeding area compared to that of the human population and modern deer teeth 87 Sr/ 86 Sr such as freshwater bivalve shells and tree cores were examined in order to track potential historic anthropogenic contamination of the water and the vegetation. The data obtained from the archeological bivalve shells show that the modern rivers yield 87 Sr/ 86 Sr ratios which are similar to those of the past. However, the tree cores registered decreasing 87 Sr/ 86 Sr values over time towards present day likely mirroring anthropogenic activities such as forest liming, coal mining and/or soil acidification. The comparison of 87 Sr/ 86 Sr of the Thuringian skeletons excavated in the same area also shows that the vegetation samples are very likely anthropogenically influenced to some extent, affecting especially 87 Sr/ 86 Sr of the shallow rooted plants.

“…The relatively rapid responses observed when restoring base cations through liming, the manual addition of basic substances such as Ca and Mg (LONG et al 1997;MOORE et al 2000), provides compelling evidence of the limitations imposed on forest function by excessive base cation removal (Table 1). While responses to liming have not been systematically examined in the U.S., liming has been used extensively to remediate the adverse effects of soil acidification in European forests (HUETTL, ZOETTL 1993).…”

Forest soil acidification and depletion of nutrient cations have been reported for several forested regions in North America, predominantly in the eastern United States, including the northeast and in the central Appalachians, but also in parts of southeastern Canada and the southern U.S. Continuing regional inputs of nitrogen and sulfur are of concern because of leaching of base cations, increased availability of soil Al, and the accumulation and ultimate transmission of acidity from forest soils to streams. Losses of calcium from forest soils and forested watersheds have now been documented as a sensitive early indicator and a functionally significant response to acid deposition for a wide range of forest soils in North America. For red spruce, a clear link has been established between acidic deposition, alterations in calcium and aluminum supplies and increased sensitivity to winter injury. Cation depletion appears to contribute to sugar maple decline on some soils, specifically the high mortality rates observed in northern Pennsylvania over the last decade. While responses to liming have not been systematically examined in North America, in a study in Pennsylvania, restoring basic cations through liming increased basal area growth of sugar maple and levels of calcium and magnesium in soil and foliage. In the San Bernardino Mountains in southern California near the west coast, the pH of the A horizon has declined by at least 2 pH units (to pH 4.0–4.3) over the past 30 years, with no detrimental effects on bole growth; presumably, because of the Mediterranean climate, base cation pools are still high and not limiting for plant growth.

“…The forest decline in Central Europe is frequently associated with declining acid neutralization capacity (ANC) and nutrient imbalances in forest soils (e.g. Hildebrand 1991, Huettl andZoettl 1993). Ground silicate rocks (mainly of basaltic and phonolitic composition) have been tested as a means to raise the pH in the affected forest soils and to provide a long-term addition of nutrients (e.g.…”

In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capita food production is the declining quality and quantity of soils. To reverse this trend and increase soil fertility soil and plant nutrients have to be replenished. This review provides a literature survey of experiences of using multi-nutrient rock fertilizers for soil fertility enhancement from temperate and tropical environments. Advantages and limitations of the application of rock fertilizers are discussed. Examples are provided from two successful nutrient replenishment projects in Africa where locally available rock fertilizers are used on highly leached acid soils. The potential of combining organic materials alongside rock fertilizers in soil fertility replenishment strategies is stressed.
