Sewage Free Soils – Guidance for Farmers and Land Managers


Farmer Guidance for Protecting Agricultural Soils from Hidden Microplastics and Chemical Contaminants in Biosolids and other Organic Fertilisers

Organic fertilisers produced from waste materials are a source of soil health-enhancing organic matter and essential crop nutrients but they are most beneficial when they are contaminant-free. Continued unmonitored application of microplastic and chemically contaminated materials to agricultural soils will impact soil functions.

As well as summarising some technical and regulatory aspects of the agricultural use of treated sewage sludge (biosolids), Fidra’s guidance warns farmers and land managers about the hidden contaminants found in biosolids and other bioresources/organic fertilisers. Avoiding the contamination of agricultural soils and the environment is a ‘nature positive’ measure to protect soil productivity and safeguard future high-quality uncontaminated food production.
