The correct option is B To maintain and improve long term fertility and sustainability of farmland
The aim of organic farming is to establish and maintain soil-plant, plant- animal and animal soil interdependence and to create a sustainable agro- ecological system based on local resources, approaching in this way the concept of functional integrity of systems. Organic farming uses environmentally friendly methods of crop and livestock production, without use of synthetic fertilizers, growth hormones, growth enhancing antibiotics, synthetic pesticides or gene manipulation. Nevertheless, organic livestock farming is not a production method which solves all problems in livestock production sustainability. As of today, it is largely seen primarily as a production method for a specific premium market requiring special management qualifications. Its high capability for meeting increased consumer demand for environmentally friendly products is associated with better quality of products alongside animal welfare.
