SCHAAF Brandenburg Technical University Cottbus, Chair of Soil Protection and Recultivation, P.O. Box 10 13 44, 03013 Cottbus, Germany The health status of forest trees and stands is determined by numerous site factors such as chemical, physical, and biological soil factors, water supply, climate, weather conditions, management history as well as atmospheric deposition impacts. In this context, the nutrient supply is an important evaluation parameter. Forest trees well supplied with nutrients are more resistant to stresses that affect the forest ecosystem than other trees. This is true for both biotic and abiotic influences. Therefore the investigation of the so-called ‘new type forest damage‘ was aimed at the exact determination of the health status of damaged trees. When considering the complete forest ecosystem, health (=vitality) means the sustainable ability to withstand negative environmental influences and still remain stable and productive. From this viewpoint, an optimal nutritional status is a prerequisite for an optimal health status. The term ‘new type forest damage‘ comprises a number of damage symptoms which have been observed in various tree specie | | 出版日期 | Book 1997 | | 关键词 | chemistry; ecosystem; ecosystems; forest; nutrition; soil | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-5402-4 | | isbn_softcover | 978-94-010-6272-5 | | isbn_ebook | 978-94-011-5402-4Series ISSN 1387-5248 | | issn_series | 1387-5248 | | copyright | Springer Science+Business Media Dordrecht 1997 |
