  1. Soil tillage in organic farming practice

  2. Objectives of soil tillage Create and maintain an optimal soil structure for the actual plants AND Keep the soil in perfect biological condition

  3. Objectives • Crumb structure • with a complex role in the soil • Available nutrients • set-aside, follows • Turning • ploughing just in special cases • Mixing • Incorporate of manures and plant residues • additives can be used only from the list of allowed materials

  4. Objectives • Weeds and pest enemies • no possibility to use any pesticide instead! • Consolidation (roll using) • water storage capacity control • erosion control • Mellowing • biological activity is the key point of the soil fertility! • Shape • multi-shape system, i.e. ridge-till

  5. Soil conservation • Erosion • alleviation of dust formation • water erosion on hill sides • Protection against structure losses • Maintain the organic material • Water management in soil • Correcting the soil condition faults

  6. Soil tillage in plantations • hill side plantations • direction of the rows! • non-organic inter-row management • herbicides • full surface disking • covered inter-rows • full surface covering • loosening the traffic lines

  7. Common problems during conversion period • management of left fallows • serious weed problems • soil compaction • on the surface • tillage pan compaction • reduced biological activity • management of conventional fields • results of faulty soil tillage system • only artificial fertilisers

  8. Reducing soil compaction • reducing the risk of inland inundation! • soil tillage at optimal moisture content • less ploughing and disking • more loosing instead • subsoiling • preferred biologically • ploughing? • if absolute necessary • in various depth

  9. Re-born non cultivated fields • non-chemical weed management • see in Organic farming chapter! • conversion period = how to restart farming • reducing weeds • improving soil stricture • improving organic material • re-established field boundaries • additional possibilities • hedges, green corridors, etc.
