Information Sheet 69: Digestate Biofertiliser - a Guide for Farmers and Regulators

Biofertilisers are fertilisers derived from anaerobic digestion of biodegradable organic materials. Through the processing of industrial and domestic food wastes, along with crop co-products, biofertilisers provide a valuable source of nutrients that support plant growth and enhance soil health.

Across the world biofertilisers have been used extensively in agriculture and forestry for many years and within New Zealand the Digestate Biofertiliser Producer Accreditation Scheme has been established by the Bioenergy Association to ensure the production of safe, high quality, consistent biofertilisers that meet the legislative and high-performance requirements for fertilisers.
