[Current]Composts, soil conditioners and mulches
Specifies requirements for composts, soil conditioners and mulches. This edition includes requirements for vermicast. It specifies minimum requirements to be met prior to labelling a product as a composted or pasteurized product. It also specifies physical and chemical requirements and documentation, which includes information to be supplied to the consumer and health warnings. Guidance is given on best practice for composting and vermicast systems designed to produce a quality product achieved by following an approved process.
