Amendment
1. An alteration to a document, product or service for a defined purpose. This will typically mean, in turf care, the addition of a material to a turf surface, or the soil, with the purpose of improving it in some way. For example: Amending the turf by the application of an acidic fertiliser to lower surface pH levels; or to hollow tine a surface to reduce thatch levels; or to incorporate sand into a soil to help improve aeration and drainage potential.
2. An effect that changes the text of an existing piece, or meaning, of legislation. An example is, The Control of Substances Hazardous to Health (Amendment) Regulations 2004.
