Organic standards have, since their origin (Soil Association 1967) required high standards of manure management, but in reality, these have not been implemented, possibly because of perceived costs of improved handling. However, a cost/benefit analysis of intermediate steps of nutrient conservation and manure handling may provide a practical solution, optimising retention of nutrients, financial and time inputs and environmental protection. Recent research on composting with conventional manures has quantified nutrient losses from heaps with different treatments (Parkinson et al, 2001). Financial and environmental costs and benefits of different management approaches are discussed. 2002 published Proceedings of the UK Organic Research 2002 Conference Organic Centre Wales, Institute of Rural Studies, University of Wales Aberystwyth Powell Jane et al.
