This Standard applies to organic products and mixtures of organic products that are to be used to amend the physical and chemical properties of natural or artificial soils and growing media. It specifies physical, chemical, biological and labelling requirements for composts, mulches, soil conditioners and related materials that have been derived largely from natural organic substances and which meet the minimum requirements as set out in this Standard. It covers materials marketed or distributed in both bags and in bulk.This Standard applies to organic products and mixtures of organic products that have been treated by composting as defined by this Standard. It also applies to otherwise treated organic products such as biosolids (sewage sludge), animal manures, tree bark, vermicasts (vermicomposts) and other organic solids used as mulches, soil conditioners, amendments or additives.It does not apply to home composting end products for self use, nor does it apply to organic fertilizers such as blood and bone. Also excluded are liquid organic wastes, liquid seaweed products, non-organic mulches (e.g. gravel), non-organic soils and soil conditioners (e.g. gypsum and sand), and materials variously described as compost starters and activators.Shredded greenwastes (sometimes referred to as garden or yard wastes) that have not been subjected to a composting procedure are specifically excluded from this Standard, mainly because they have a high probability of containing weed and plant pathogen propagules. Adherence to the criteria given in the Best Practice Guidelines should lead to the production of quality compost that will not spread weeds and plant pathogens.Test methods for the analysis of these materials are set out in Appendices A to J.NOTE: Appendix K gives guidance on best practice, Appendix L gives guidance on the determination of compliance with this Standard. AS 1199 and its guide AS 1399 give guidance on sampling.
