Research paper thumbnail of Carbon routes from decomposing plant residues and living roots into soil food webs assessed with 13C labelling

Soil Biology and Biochemistry, 2008

This field experiment investigated how C from fresh organic amendments and from a growing leek cr... more This field experiment investigated how C from fresh organic amendments and from a growing leek crop was allocated into different soil microbial and faunal groups in an arable field. A 13C-enriched red clover green manure was incorporated in one treatment, while the growing leek crop was pulse labelled with 13CO2 in another. Incorporation of 13C into microbial fatty acids, micro-

Research paper thumbnail of Clover cover crops under-sown in winter wheat increase yield of subsequent spring barley—Effect of N dose and companion grass

Field Crops Research, 2011

Research paper thumbnail of Use of Red Clover-Based Green Manure in Leek Cultivation

Biological Agriculture & Horticulture, 2008

The application rates were based on concentrations of nitrogen (N) and carbon (C) in the clover roots and shoots in the direct incorporation treatment, and the N-availability. A practically appropriate mulch application rate was included for

Research paper thumbnail of Influence of various forms of green manure amendment on soil microbial community composition, enzyme activity and nutrient levels in leek

Applied Soil Ecology, 2007

Research paper thumbnail of Soil enzyme activities, microbial community composition and function after 47 years of continuous green manuring

Research paper thumbnail of The N and S status in cropping systems with white cabbage as influenced by organic fertilizers

Acta Agriculturae Scandinavica, Section B - Soil & Plant Science, 2012

Fresh and anaerobically digested red clover were compared as N and S sources in a incubation expe... more Fresh and anaerobically digested red clover were compared as N and S sources in a incubation experiment without plants and a pot experiment with white cabbage, both conducted in climate chambers. The hypothesis was that anaerobic digestion would increase S availability in relation to N and that arylsulphatase activity would be higher in treatments with S deficiency. Besides the two
