New publication with the participation of eLTER site Zöbelboden: Disentangling climate from soil nutrient effects on plant biomass production using a multispecies phytometer

2 November 2021

Plant biomass production is co-dependent on climatic and edaphic factors, which in turn are under increasingly anthropogenic pressure. Disentangling effects of climate and soil on plant biomass production is challenging, especially along large climatic gradients. To address this, a multispecies phytometer was developed (i.e., standardized plant community in local site soils and a standardized substrate) and installed in 18 sites across a pan-European aridity gradient.

The study revealed that aridity and phosphorous availability were the strongest determinants of biomass production, with each species experiencing its own unique set of co-limitations. Moreover, this study demonstrates that the phytometer approach has the potential for disentangling effects of climate and soil on plant biomass production and offers a flexible protocol for investigating additional drivers such as the link between soil microorganisms and plant productivity. Distributed experiment designs are of increasing importance for unraveling the effects of multiple drivers on ecosystems in a changing world.
