Abstract

Phosphorus is one of the major limiting factors of primary productivity in terrestrial ecosystems and, thus, the P demand of plants might be among the most important drivers of soil and ecosystem development.The P cycling in forest ecosystems seems an ideal example to illustrate the concept ofecosystem nutrition. Ecosystem nutrition combines and extents the traditional concepts of nutrientcycling and ecosystem ecology. The major extension is to consider also the loading and unloadingof nutrient cycles and the impact of nutrient acquiring and recycling processes on overall ecosystem properties. Ecosystem nutrition aims to integrate nutrient related aspects at different scales and indifferent ecosystem compartments including all processes, interactions and feedbacks associated with the nutrition of an ecosystem. We review numerous previous studies dealing with P nutrition from this ecosystemnutrition perspective. The available information contributes to the description ofbasic ecosystem characteristics such as emergence, hierarchy, and robustness. In result, we wereable to refine Odum’s hypothesis on P nutrition strategies along ecosystem succession to substraterelated ecosystem nutrition and development.We hypothesize that at sites rich in mineral-bound P,plant and microbial communities tend to introduce P from primary minerals into the biogeochemicalP cycle (acquiring systems), and hence the tightness of the P cycle is ofminor relevance for ecosystemfunctioning. In contrast, tight P recycling is a crucial emergent property of forest ecosystems established at sites poor in mineral bound P (recycling systems). We conclude that the integration of knowledge on nutrient cycling, soil science, and ecosystemecology into holistic ecosystemnutrition will provide an entirely new view on soil–plant–microbe interactions.Key words: ecosystem properties / P recycling / P nutrition strategy / forest nutrition / P acquiring
