| 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)... |

| 1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role. 2. To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta-analysis with field measurements across a European-wide network of sites. In the meta-analysis, we related crop species averages of leaf N, leaf-dry matter content, fine-root C and N, with SOC stocks and sequestration... |

| Die Umstellung vom Pflug auf eine reduzierte Bodenbearbeitung wird als Möglichkeit zur Minderung des Klimawandels im Zusammenhang mit einer erhöhten Humusanreicherung diskutiert. Ob reduzierte Bodenbearbeitungssysteme im biologischen Landbau zu einer erhöhten Lachgas-Entwicklung (N2O) führen, wurde bisher nur wenig beleuchtet. Im Langzeit-Bodenbearbeitungsversuch des FiBL in Frick wurden daher N2O-Emissionen über zwei Jahre hinweg und die Humusvorräte dreizehn Jahre nach Versuchsbeginn bis in eine Tiefe von 50 cm gemessen und mit weiteren mitteleuropäischen Studien verglichen. Die kürzlich publizierte Studie von Krauss et al. (2017) zeigt, dass es bei den N2O-Emissionen in der Weizen- und Kunstwiesenperiode keine Unterschiede zwischen den... |
