; (C) a strategy to monitor and adaptively manage implementation of the action plan, including implementation of applicable eligible activities, that— (i) leverages, to the maximum extent practicable, ongoing water quality monitoring activities carried out in the watershed by non-profit organizations, colleges and universities, and Federal, State, and local government agencies; and (ii) provides for the development and validation of integrated, reliable, and easy-to-use models for predicting changes in dissolved reactive phosphorus arising from implementation of such eligible activities; and (D) a strategy for enhanced outreach to identify and recruit eligible partners and producers in the watershed to increase adoption of eligible activities determined to be effective by the Secretary under subparagraph (B). (d) Prioritization The Secretary shall prioritize entering into covered agreements to demonstrate— (1) non-digester methods to transition from wet manure handling and storage to dry manure handling and storage, including open solar drying or composting of manure onsite, conversion of dairy and livestock operations to pasture-based management, solid separation technologies, vermifiltration, and scrape conversion, provided that such methods do not otherwise result in the discharge or runoff of wastewater with high dissolved phosphorus content into a watershed; (2) methods to reduce dissolved reactive phosphorus inputs to a priority watershed from land characterized by phosphorus— (A) that has accumulated from prior agricultural land management activities; and (B) the levels of which exceed agronomic rates
