Abstract

Species diversity and functional gene diversity of soil nitrite oxidising bacteria at the Fasset Hill site will be characterised by rDNA and norB sequence analysis in enrichment cultures and extracted soil DNA. The effects of carbon and nitrogen amendment, pH, water content and heavy metals on nitrification and denitrification will be determined, using 15N techniques in controlled microcosm experiments, and their impact on nitrite community structure will be assessed. The effects of these factors, resulting from changes in management practices, will be determined by molecular analysis and measurement of nitrification and denitrification rates in field experiments. The study will assess the influence of management practices on the boidiversity of an important bet poorly characterised bacterial group on the soil nitrogen cycle.
