The mycorrhizal contribution to plant productivity, plant nutrition and soil structure in experimental grassland.
Previous studies have shown that arbuscular mycorrhizal fungi (AMF) can influence plant diversity and ecosystem productivity. However, little is known about the effects of AMF and different AMF taxa on other important community properties such as nutrient acquisition, plant survival and soil structure. We established experimental grassland microcosms and tested the impact of AMF and of differen...
متن کاملMycorrhizal Fungi and Plant Nutrition
The term “mycorrhiza” was coined by A. B. Frank, a scientist in Germany, more than 100 years ago. It literally means fungus-root, and describes the mutualistic association existing between a group of soil fungi and higher plants. The association is based on the plant component providing carbohydrates and other essential organic compounds to the fungi. In return, the fungal component, which colo...
متن کاملSymbiotic bacteria as a determinant of plant community structure and plant productivity in dune grassland.
Symbiotic interactions are thought to play a key role in ecosystems. Empirical evidence for the impact of symbiotic bacteria on plant communities is, however, extremely scarce because of experimental constraints. Here, in three complementary experiments, we show that nitrogen-fixing rhizobia bacteria act as a determinant of plant community structure and diversity. Grassland microcosms inoculate...
متن کاملContribution of above- and below-ground plant traits to the structure and function of grassland soil microbial communities.
BACKGROUND AND AIMS Abiotic properties of soil are known to be major drivers of the microbial community within it. Our understanding of how soil microbial properties are related to the functional structure and diversity of plant communities, however, is limited and largely restricted to above-ground plant traits, with the role of below-ground traits being poorly understood. This study investiga...
متن کاملTerrestrial plant productivity and soil moisture constraints
Croplands cover 12% of the ice-free land surface and play an important role in the global carbon cycle. Light use efficiency (LUE) models have often been employed to estimate the exchange of CO2 between croplands and the atmosphere. A key parameter in these models is the maximum light use efficiency ( *NPP), but estimates of *NPP vary by at least a factor 2. Here we used 12 agricultural eddy-fl...
