Forschergruppe (FOR) 456 degree of celsius: The role of Biodiversity for element cycling and trophic interactions: An experimental approach in a grassland community, Biodiversität - Effects of plant diversity on the soil nutrient cycle

Description: Species and/or functional diversity of experimental grassland communities may influence the soil nutrient cycle. The objektives of our proposal are (1) to quantify nutrient retention (N, P, Ca, Mg, S, Cu, Mn, Zn) by setting up an ecosystem budget including all inputs and outputs, (2) to determine the contribution of organic N, P an S in soil solution to nutrient cycling, and (3) to assess soil N processes with the help of the N isotope composition in inorganic N species in differently diverse experimental grassland communities. We will collect soil solid phase samples, precipitation above an below the grass canopy, and soil solution with porous suction plates at 5, 15, 30, 60 and 120 cm soil depth in one of the four blocks of the Jena biodiversity experiment (22 plots).
