Nitrogen mineralisation and plant nitrogen acquisition in a nitrogen-limited calcareous grassland

Autor: Murray Unkovich, Ross Monaghan, Nicola Jamieson, D. Barraclough

Publikováno v: Environmental and Experimental Botany. 40:209-219

A field study measured the rate of soil mineral N supply and its effects on plant biomass and N accumulation in a 13-year-old, naturally regenerating, calcareous grassland. Gross rates of N mineralisation (2 μg g −1 day −1 , i.e. 0.69 kg ha −1

Soil N dynamics in a natural calcareous grassland under a changing climate

Autor: Murray Unkovich, Nicola Jamieson, D. Barraclough, R. Monaghan

Publikováno v: ResearcherID

This paper reports the results from a medium-term field scale investigation into the effects of simulated climate change on soil N mineralisation in a semi-natural calcareous grassland in southern England. The experiment utilised soil warming cables,

Biocide manipulation of N flow to investigate root/microbe competition in forest soil

Autor: Nicola Jamieson, Kenneth Stuart Killham

Publikováno v: Plant and Soil. 159:283-290

Root/microbe competition was investigated as a mechanism controlling fertilizer N uptake by coniferous forest trees. Combinations of biocides both with and without 15N labelled urea, were applied to microcosms containing Sitka spruce seedlings, to se
