Sludge and Compost Analysis

Many non-farmyard activities produce valuable organic fertilisers in the form of sludges and composts.  Such materials have the potential to enhance soil by the addition of organic matter and nutrients for plant growth.  Whether the soil is used to grow forage, arable crops or vegetables, the end product becomes part of the human food chain.  Consequently all fertiliser materials that are applied to the soil must comply with stringent quality standards.

For a material to be acceptable as safe to add to soil, and has beneficial qualities, the minimum information required is:
pH, Organic Matter Content, Mineral Profile, Heavy Metal Content, Microbiology Screen (e.g. Salmonella etc.)


The presence of any undesirable organic or inorganic chemicals will render a material unfit for use.
