Co2Mpositiv- Optimization Of Organic Materials Cycles Of Viticulture In Luxembourg

Summary

The residue grape marc is transformed into a regional, high-quality fertiliser by optimizing the composting process. Ways are shown that improve the organic materials cycles in Luxembourg's viticulture in order to minimize the need for mineral nitrogen and phosphate fertilizers and pesticides. The use of the composting process in agriculture and the use of compost products are one possibility to increase sustainability and counteract climate change.Locally produced compost products help to promote humus formation and thus help to protect the climate. The aim of the project is to promote wide support for organic fertilisation and composting. Thus, first windrow composting, where grape marc, green waste and other biodegradable material are mixed, has started in 2019. The compost as well as compost tea are applied on trial plots in an organic vineyard to investigate the effects on soil fertility.
