Toetsing van de Groene Weide Meststof in de praktijk: Demovelden van de gebiedsgerichte pilot Kunstmestvrije Achterhoek, 2020

The aim of the project Biobased Fertilisers Achterhoek (in Dutch: Kunstmestvrije Achterhoek) is to make fertilisation practice more sustainable by means of the use of locally available nutrients from renewable sources. The project is, as a regional pilot, part of the sixth action program of the Netherlands serving the Nitrates Directive. One of the objectives is to identify the eligible product quality and product composition of fertilising products from animal manure and sludge which can be produced by means of best available techniques for manure and sludge processing. For this objective WUR-Wageningen Environmental Research (WUR-WENR) has developed a monitoring program. A research topic is testing of a new fertilising product from animal manure and other (most renewable) nitrogen sources in demonstration field experiments. The research started in 2018. This document reports the results of the third and last year 2020.
