| As part of the TILMAN-ORG CORE ORGANIC II project, data on the use of reduced tillage in organic farming systems from a range of field trials and the published literature was compiled. A meta-analysis was conducted to determine the impacts of reduced tillage on crop yields, weed pressure and soil organic C stocks. This paper highlights some of the key findings from this study. |

| The present field study documents substantial changes in the soil microbial community (SMC) and organic matter (SOM) in an upland pasture soil resulting from 10 years of “cattle outdoor over-wintering practice”. Soils from a long-term investigated pasture area were compared under three different levels of cattle impact (SI – severe, MI – moderate, NI – no impact). Extended polar lipids analysis (PLA) confirmed a qualitatively new microbial community profile and a several-fold increase of the microbial biomass in the impacted soils (SI) compared to the control NI soil. The new SMC was derived from cattle intestine microorganisms, typical by increased content of archaeal phospholipid ether lipids and by new fatty acids indicative for bacterial and fungal... |

| A continuous labelling experiment using 13C-CO2 was set up in open-top chambers in order to follow fluxes of assimilates from the plant into the rhizosphere. Labelling was performed for one growing season by adding low amounts of CO2 depleted in 13C to the atmosphere of the open-top chambers, resulting in a difference of ∆ 13C 5‰ V-PDB compared to ambient conditions. The label was recovered in both plant parts and soil microbial communities, analysed via phospholipid fatty acid (PLFA) side chains. PLFA 18:2ω6,9 showed a significant incorporation of the 13C label in October, indicating that fungi utilized plant derived carbon. In bacterial PLFA no label incorporation was detected, probably due to a lower use of rhizodeposits or a preference to older carbon... |
