Soil and climate friendly crop production in organic farming

Experiences from previous projects focussing on reduced tillage will be tested on-farm (Module 1). Beyond, the climate impact of reduced tillage under organic conditions, especially the greenhouse gas emissions (GHG), will be assessed (Module 2).

• Module 1 (on-farm assessment): In each of three selected regions (Western Switzerland, Canton of Berne and,Eastern Switzerland) 10 pioneer farms will fully or partly convert to reduced tillage. The main focus are on weed management, yield performance and their optimization. Based on their own experiences, pioneer farmers will share their knowledge with interested colleagues through field excursions, machine demonstrations, articles in magazines and blogs.
• Module 2 (GHG emissions and carbon sequestration linked with reduced tillage and organic fertilization): On the scientific field trial at FiBL Frick, nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) emissions will be assessed weekly and event based in 16 subplots over a period of 2.5 years. In combination with the determination of carbon sequestration (0 – 50 cm), the climate footprint will finally indicate whether reduced tillage is more climate friendly than ploughing. GHG data will be used for the calibration of biogeochemical models (DAYCENT).
