Abstract

The overall goal of the study is to determine the significance of amino acids as a N source and growth regulator in agricultural grasslands. To achieve this objective we will examine the ability of different agriculturally important grasses to take-up and use a range of abundant amino acids for growth. Both soil and hydroponic studies will be carried out using dual labelled amino acids (15N and 13C) to determine whether grass species can compete effectively with rhizosphere micro-organisms for amino acids. This technique will also indicate whether amino acids are taken up directly by plant roots or following mineralisation to inorganic N. We will also examine the importance of vesicular-arbuscular mycorrhizae in amino acid uptake, and determine the significance of organic N in the regulation of plant community structure and productivity in grassland systems.
