Abstract
The overall aim of this study is to test the low-input agricultural grasslands whether competition for soil N between plant and microbes is avoided through niche partitioning of the differently available forms of N, but especially amino acids, in soil. Specific hypotheses to be tested are: that plants and soil microbes preferentially utilise different amino acids that are available in soil, thereby avoiding competition for organic N; that inter-specific competition for N within the plant community is likewise minimised due to niche differentiation in timing and chemical from of N uptake; and that species dominance within the plant community is correlated with uptake of the most available soil N form.
