Plant Soil Interactions

Soils are highly diverse. A hand full of soil contains billions of bacteria and tens of thousands taxa of bacteria, fungi and other soil biota. In other words, microbes represent the unseen majority of life on Earth. The significance of soil microbial diversity for plants and for the functioning of agricultural and natural ecosystems is still poorly understood. In our work we investigate how changes in soil microbial biodiversity and land use impact plants and ecosystem functioning. Specific attention is given to one of the oldest and most widespread symbiosis on the Earth, the symbiosis between plants and arbuscular mycorrhizal (AM) fungi. We investigate effects of AM fungi and AM fungal diversity on plant growth, nutrient cycling and ecosystem sustainability. Our results demonstrate that soil microbial communities enhance the sustainability of agro-ecosystems by promoting plant nutrient uptake and reducing nutrient losses. Our recent results revealed that the loss of soil biodiversity impairs ecosystem functioning and reduces ecosystem multifunctionality.
