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