Today's farming suffers under great pressure from both economical and environmental demands. These demands forces today's farmer to be more efficient only to survive. One solution could be the use of conservation tillage which is a system where the soil is tilled without ploughing. The cultivation is shallow and the machinery leaves the residues in the top layer of the soil. The purpose with this project has been to investigate if it's an option to use conservation tillage at a farm size of 100 ha with the following crop sequence: • Sugar beets • Winter wheat • Brewer's barley + re-seed • Winter rape/red clover • Winter wheat (winter wheat + mustard in the conservated system) We have compared conventional farming (mouldboard ploughing) with conservation tillage and we have come to the following conclusions: • Less manpower with 0,65 h/ha • Less labour costs with 116 Skr/ha • Less fuel costs with 96 Skr/ha • Machinery savings with 321 Skr/ha • Increased gross margin with 868 Skr/ha From environmental view we have been able to state the following facts: • Less erosion • Increased water quality • Increased soil quality • Decreased use of pesticides when using good crop sequences • Less pesticide in the nature
