| The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)... |

| The interest in methods to proof organic food authenticity increases with the steadily rising popularity of food labelled organic. Profiling techniques enable the detection of a wide range of substances in biological samples. Together with bioinformatics tools these techniques are useful for biomarker searching, e. g. in plant extracts. Metabolomic and proteomic profiling techniques were used to screen organic and conventional wheat, originating from the DOK field trial in Switzerland. Up to 11 wheat varieties from three harvest years were analysed. We were able to detect a number of metabolites and proteins with significant differences between samples of conventional and organic grown wheat of the variety “Runal”. Results viewed across all 11 varieties... |
