POL.215-Compost and Phosphorous: Managing Regulations and Risks-AC22.USCC

For decades, compost (and other organic recycled product) application rates have been governed by the amount of plant available nitrogen they provide. However, over the last 5-10 years, concerns about phosphorous application, and its effect on the environment, have led to State regulation limiting its application. Currently, 16 states have phosphorus regulation in place, and in many states, it limits the amount of compost that can be used in specific applications. In most states, politically expedient and not scientifically valid regulations have been established. The hardest hit markets are turf maintenance, which can be high value markets for compost.   The paper will outline Findings identified in the development of a Minnesota white paper on phosphorous risk in various applications of compost, Suggestions on limiting phosphorous risk, Options for how the composting industry can curtail the expansion of phosphorous regulation, and New labeling options for promoting the slowly releasing nature of phosphorous.
