Overview

Overview

Anaerobic digestate and compost can be considered renewable fertilisers, much like livestock slurry and farmyard manure.

These guides provide an introduction to compost and anaerobic digestate, how they should be integrated into farm nutrient planning, and how they should be applied to the field.

These guides are intended to complement rather than replace other statutory or good practice guidance for handling these materials.

As part of this guidance WRAP has developed two separate guides for farmers, growers and advisers
and agricultural contractors (covering haulage and application). A further reference version has also been developed, for anyone interested in understanding the guidance in greater detail.
