29. Concluding Conference of the KASSA project 20-21 February 2006, Brussels, Belgium Conclusions Up to now, low adoption of conservation agriculture in practice A lot of basic research sometimes based on long-term experiments Cost reduction most important driving force Erosion and degradation of soils driving forces in some cases Most soils are suitable Large farms are favoured Pollutants behave differently in differently tilled soils Process toward CA is on-going step-by-step Economic, technical, and sociological risks should be assessed Knowledge generation and sharing is the key point
