Guide to good practices for digestate spreading to maximise the agronomic value and minimise impacts on soil fertility

FERTI-DIG

Research

Methanisation, encouraged by regulations and the societal context, seems to be a relevant solution to contribute to energetic transition and to territorial circular economies. Nevertheless, given the wide-scale development of methanisation in France, it is important to monitor fertilisation with digestate to ensure optimal plant nutrition and limit the associated impacts. Agronomic use of digestates involves understanding drivers of physico-chemical characteristics and effects on soil fertility as a function of the source of the digestate, as well as spreading, soil and climate contexts.

The overall aim of the FERTI-DIG project (ADEME/GRDF, 2021-2023) is to produce a guide to good practices for digestate spreading to help improve the sustainability of methanisation.
