During the last decade , there has been a strong discussion about the principles of constitutive farming , drive in the main by the differences in organic production systems in Europe . Some systems are highly deepen and focalise on high-pitched economic sustainability whereas others focus on increase biodiversity and implementing agroecological principles . The first results of the European enquiry project GREENRESILIENT , affect UvA researchers Paul van Rijn and Arne Janssen , now show that growing light - hertz green manure species guarantees a relatively wearisome spill of grime mineral N over time , whereas soil solarization immediately provides a high story of dirt mineral nitrogen , which can potentially leach and cause negative environmental impacts .

The main objective of the GREENRESILIENT project , which started in April 2018 and is now midway , is to manifest that an agroecological approach to greenhouse production is workable and can enable robust agroecosystems in different European areas . The task hypothesis is that the effectuation of more live production organization , based on low Energy Department consumption , appropriate harvest gyration , use of agroecological service craw ( ASCs ) and local organic amendments , is potential at almost any parallel in Europe . Eighteen months after the kickoff of the undertaking , the main inquiry activities carry out so far seem to support the conjecture , but further studies are involve .
Experimental sitesThe five experimental website of the project ( located in Belgium , Denmark , France , Italy and Switzerland ) compare two type of production organisation in protect conditions :
The BAU and INN scheme are assessed concord to a multidisciplinary approach , looking at crop production , nutritious availability , soil birth rate , soil wellness , operative biodiversity ( nematodes , microbiological activity , gage biodiversity , diseases and pests ) and life cycle analysis . Paul van Rijn and Arne Janssen , researchers at the UvA Institute for Biodiversity and Ecosystem Dynamics , are are responsible for the intent and depth psychology of monitor the arthropod with direction on gadfly , rude enemies and other functional groups .

Preliminary resultsPreliminary resolution indicate that growing myopic - cycle green manure species guarantee a comparatively deadening release of soil mineral nitrogen over time , whereas soil solarisation immediately provides a high level of soil mineral nitrogen , which can potentially percolate and cause negative environmental shock .
Growers , insurance makers and the general public had a chance to learn more about these maturation and see the observational sites at Open House events , which will be repeated during the coming grow time of year . Consumers also had the chance to get involved in the project and learn about diversified output systems at targeted effect in Switzerland , Denmark and Italy .
