An amendment is any material that is added to garden soil to improve or enhance its characteristics, such as structure or fertility. Also, amendments can be used to alter a soil’s pH. Compost, worm castings, manure, lime, and sulfur all qualify as soil amendments. Strictly speaking, fertilizers can be considered amendments as well, but in general, we view amendments as soil enhancers, builders, or improvers as opposed to straight nutrients.
