Progress 09/15/04 to 09/14/06
Outputs Project evaluation component completed preliminary assessment of models (formative and process program theory and program logic). Evaluation indicates that new collaborations have increased stakeholder awareness and increased visibility of the project. Further Iowa-based stakeholder outreach and learning about system solutions for nutrient management and water quality was conducted through a sub-project, Green Lands Blue Waters Iowa Organizing. Research and demonstration to support multifunctional agriculture and identify value and opportunity for eco-system and social solutions was conducted through four projects: Grassland Agriculture, Living Mulch, Winter Grazing, and Gordon's Marsh. Grassland Agriculture project investigator focused on on-farm ruminant grazing and identified research priorities, supported education and learning through conferences and workshops, and engaged new partners. Investigators for Living Mulch project conducted research, identified
production and management alternatives, evaluated costs and conducted educational training on diversifying traditional soybean systems through use of living mulch systems. Investigators for Winter Grazing researched and identified profitability, gains, and system production management tradeoffs for feeding supplemental distillers dried grains to fall-calving cows grazing stockpiled forage over winter and as a creep feed to their calves. A subwatershed case study, Gordon's Marsh, investigated social and economic parameters for voluntary conversion of private land to wetlands.
Impacts The projects demonstrate and document management practices and costs and have resulted in increased understanding for producers, extension agents, feed company representatives, and non-governmental agents regarding several production and conservation alternatives that show potential as win-win scenarios for both farmer profitability and the environment.

Progress 01/01/05 to 12/31/05
Outputs Project evaluation component is conducting assessments of progress toward overall project goals using formative and process program theory approach and program logic approach. For the research, outreach, and demonstration elements of the project, eight projects are active. One project builds on earlier grazing work to assess a beef production system based on fall-calving cows grazing stockpiled forage with minimal supplementation during winter. Two projects with scientists and farmer cooperators are conducting research and demonstrations on diversifying traditional agricultural production systems through the use of double-cropping field peas with soybeans (includes feeding trials) and growing living mulches (alfalfa, kura clover, and birdsfoot trefoil in simple and binary mixes and orchardgrass and reed canarygrass in three-way mixes in a corn-soybean-forage rotation with all phases present each year). A cover crop use survey to identify barriers and opportunities for
cover crop use has been conducted and is being analyzed. At the watershed level, the Center for Agricultural and Rural Development and a local USDA-NRCS resource conservation district along with numerous partners are documenting the social, geophysical and economic history of a subwatershed scale wetland conversion and exploring assessment of conservation and land use benefits in a local watershed. At landscape scale, two nonprofit partners under the auspices of the regional Green Lands Blue Waters consortium are working separately to coordinate a regional project and to conduct related state-level meetings, both with an ultimate goal of increasing the use of continuous living cover on the land.
Impacts The aggregate impact of the initiated projects is to support scientists and farmers who want to investigate and invest in the multi-functional aspects of agricultural landscapes. With respect to research and demonstration, we expect that a better understanding of eco-system services and their economic value will facilitate transition to a generation of agricultural systems with optimized environmental and economic performance. With respect to stakeholder organizing, we expect that new collaborations will raise the visibility of and increase resource investment in activities that support development and adoption of agricultural systems that reduce harmful runoff and nutrient loss in strategic Midwest watersheds.

Progress 01/01/04 to 12/31/04
Outputs Project evaluation component initiated preliminary assessment of two models for appropriate fit to the overall project goals. The two models explored were a formative and process program theory approach and a program logic approach. For the research, outreach, and demonstration elements of the project, five subcontracts have been issued. A Grassland Agriculture project is conducting outreach, engaging stakeholders, and identifying potential research priorities for grassland related agriculture. Two projects with scientists and farmer cooperators have been identified and subcontracted to conduct research on diversifying traditional agricultural production systems through the use of living mulch and double-cropping. One water management project has been identified and subcontracted to document the social, geo-physical and economic history of a subwatershed scale wetland conversion. A non-profit partner has been engaged and is designing a project plan for state-wide
organization of stakeholders whose nutrient management and water quality interests are regional and/or Basin-wide.
