Project Title

DükonaR Fertilizer concentrates from remnants

Project description

The nutrient report of Lower Saxony 2016/2017 shows considerabe surpluses of nitrogen and phosphorus, especially for the Weser-Ems region. According to the new Fertilizer Application Ordinance even more nutrients will have to be exported. The aims of the project are developing and testing an enclosed composting process which leads to a solid fraction, containing mostly phosphorous and a liquid one of concentrated nitrogen. Mixing of liquid manure or fermentation residues with structural aids, such as straw or others usable humus is being planned. The exhaust is cleaned and the nitrogen is concentrated in the washing water. This process is planned with the participation of manufacturers of corresponding plant components and imploemented on a local farm. This enables research under practical conditions, which is of considerable relevance to the evaluation and transferability of the results into practice.
