Journal ArticleDOI
Vascular plant success in a warming Antarctic may be due to efficient nitrogen acquisition
Paul W. Hill,John Farrar,Paula Roberts,Mark Farrell,Mark Farrell,Mark Farrell,Helen Grant,Kevin K. Newsham,David Hopkins,David Hopkins,Richard D. Bardgett,Davey L. Jones +11 more
TL;DR: Research demonstrates that via a short circuit in the terrestrial nitrogen cycle, Antarctic hair grass acquires soil nitrogen more efficiently than competing mosses, which may explain its success in a warming maritime Antarctic.
Journal ArticleDOI
Protein breakdown represents a major bottleneck in nitrogen cycling in grassland soils.
TL;DR: In this article, the authors investigated the influence of a range of environmental factors on the rate of protein mineralization in a grazed grassland and fallow agricultural soil and found that protein turnover rates were directly compared to the rates of amino acid mineralization under the same conditions.
Journal ArticleDOI
Turnover of low molecular weight dissolved organic C (DOC) and microbial C exhibit different temperature sensitivities in Arctic tundra soils
TL;DR: In this paper, a double first order exponential kinetic equation with rate constants k1 and k2 was used to investigate the influence of substrate concentration on C cycling in high Arctic tundra soils, using soil solutions spiked with either 14C-labeled glucose or amino acids.
Journal ArticleDOI
Microbial competition for nitrogen and carbon is as intense in the subsoil as in the topsoil
David L. Jones,Ebtsam Magthab,Deirdre B. Gleeson,Paul W. Hill,Antonio Rafael Sánchez-Rodríguez,Paula Roberts,Tida Ge,Daniel Murphy +7 more
TL;DR: In this article, the relationship between root distribution, organic and inorganic N availability and potential N supply at the critical growth period during the wheat cropping cycle in a sand textured Eutric Cambisol was evaluated.
Journal ArticleDOI
Acquisition and Assimilation of Nitrogen as Peptide-Bound and D-Enantiomers of Amino Acids by Wheat
Paul W. Hill,Richard S. Quilliam,Thomas H. DeLuca,John Farrar,Mark Farrell,Mark Farrell,Mark Farrell,Paula Roberts,Kevin K. Newsham,David Hopkins,David Hopkins,David Hopkins,Richard D. Bardgett,David L. Jones +13 more
TL;DR: It is concluded that wheat is able to utilise L-peptide and D-amino acid N at rates comparable to those of N forms of acknowledged importance, namely L-aminos acids and inorganic N.
