keywords: Cycling, Nitrogen, Phosphorus, Sustainability, Soil composition
abstract: This paper examines the sustainability of nutrient cycling on organic farms. After a brief consideration of the principles of nutrient cycling in organic agriculture, data on soil P and K indices and farm nutrient budgets is used to assess the integrity of nutrient cycling, including some consideration of losses to the environment. An attempt is made to assess the wider sustainability of organic farming in the context of the limited amount of recycling possible.
