Even though the ethos of organic agriculture concerns animal welfare and environmentally friendly production, certain undesirable inputs are permitted in organic farming by the European Commission Regulation (EC) No 889/2008. The EU Horizon 2020 project Organic-PLUS (https://organic-plus.net) has investigated the possibility to phase out a range of contentious inputs: Plant inputs: Copper, sulphur, and mineral oils; Soil inputs: Conventional manure, plastic, and peat; Livestock inputs: conventional straw, antibiotic medicine, and anthelmintic medicine (against parasites). Organic-PLUS has performed a feasibility study to investigate advantages and disadvantages of both the current production methods with the contentious inputs and proposed alternative methods where the- inputs have been phased out or substituted. The feasibility, sustainability and environmental impact have been evaluated involving stakeholders and decision-makers (e.g., farmers, advisers, developers). In this multi-actor approach seven case farms in Denmark (Northern Europe), Germany (Central Europe) and Spain (Southern Europe) were selected, including the following organic production branches: Pig, poultry, vegetables, cereals, potato, apple, and wine. Results of the case farm studies include: · It is feasible to replace plastic folio for weed control with alternative products (bioplastic or paper mulching) · It is feasible to replace conventional animal manure with alternative fertilizers, such as digestates from biogas production, green waste compost or organic bio fertilizer, combined with crop rotation with legumes · It is not feasible to phase out antibiotics and anthelmintics completely since sick animals must be treated. However, it is feasible to reduce the consumption significantly without reducing production quantity and quality · It is feasible to replace sulphur for apple production with organic approved fungicides · It is not feasible to phase out copper completely for the wine varieties grown today without a very large decrease in quality and yield. |
