Innovation

Innovative solutions sometimes come from an unexpected corner! In Vijlen, Limburg, a trial was conducted with the processing of organic residual waste from the landscape. The soil structure is improved by composting the organic residual waste and processing it on site. The compost in the soil therefore retains more moisture when it rains, prevents dehydration and the soil being washed away. CO2 is reduced by “cold composting” the organic material. By processing it on site, less energy and emissions (CO2 and N) are required in the form of transport of residual flows.

Bokashi

Bokashi is an old Japanese technique. It is also called “cold composting”. It is a way to make plant residues, such as natural grass or hedge trimmings that are released during landscape management, suitable for soil improvement. The plant residues are processed with fermentation. It is an anaerobic process, that is, without oxygen, and therefore without combustion. This keeps all carbon and nitrogen in the material. The utilization of residual flows from landscape management for soil improvement fits in with circular agriculture.

On 7 November, under the leadership of Bokashi expert Philippe van der Grinten, a Bokashi heap was set up with around 70 m3 and 40 tonnes of cuttings in Vijlen. The cuttings came from 6 hectares, 2nd mowing wet hay land in the Geuldal. It is a week old, damp (<50% dry matter).

This as part of the climate-smart landscape management project (Wageningen University) and process biomass from the landscape differently (POP3, Province of Limburg).
