Agrifirm Plant, together with a series of involved parties, on 26 September in Vredepeel started accelerated research that is focused on the organic decontamination of soil that is contaminated with nematodes. This new and unique way of ground treatment (‘Soil Resetting’) addresses the question of the use of the usual product, Monam. ‘Soil Resetting’ can offer an environmentally friendly – and safe for neighbours – alternative to the use of Monam. Since 25 August, the use of Monam has only been permitted with strict preconditions. The project is financed in 2104 by the Ministry of Economic Affairs, which approved the request from LTO Nederland.
Organic ground decontamination
An existing version of biological ground decontamination has already been applied for several years in outdoor cultivation. With this, a large amount of organic material, mostly grass, is worked into the soil, after which the soil is covered. The results of this method are sometimes variable and often not practical due to the large volume of grass (40 ton/ha) that must be applied and worked in. In addition, it must be carried out during a six-week period in the summer. This costs a cultivation season, and thus income.
The company Thatchtec, together with Wageningen University, developed a product, Herbie®. It is an easily degradable protein that has a constant and known quality and comes from plant waste streams from the agro-industry. The product is available in both grain and liquid form. The product is worked into the soil, after which the soil will be covered for two to three weeks. In greenhouses, good results have been achieved with this. If the method also works well in outdoor cultivation, it’s much more practical and can be carried out in a shorter time than the existing version of biological ground decontamination.
In the project, research is done into the effectiveness of the method on different nematodes and into various factors that have an influence on the effectiveness and costs. The research started this year on three parcels: on parcel contaminated with Meloidogyne chitwoodi (root-knot nematode) in Limburg, a parcel contaminated with the potato cyst nematode, Pratylenchus penetrans (lesion nematode), and Trichodoriden (stubby-root nematode) in Drenthe and a parcel contaminated with Ditylenchus dipsaci (stem nematode) in North-Holland.
The project is financed in 2014 by the Ministry of Economic Affairs, which approved the request from LTO Nederland. The collaborating partners – Agrifirm Plant, PPO-AGV, Thatchtec, BLGG, SoilCares Research and LTO – hope to carry on the now-accelerated research in the period of 2015-2018.
