The 4R Plus program is a science-based framework designed to increase awareness and provide information about 4R nutrient stewardship and conservation practices to crop advisers and farmers. These 4R Plus practices can improve soil health, crop yields and water quality.
4R Plus combines the 4Rs of nutrient stewardship – applying the right source of fertilizer at the right rate and right time and in the right place – with the “Plus” conservation practices like cover crops, no-till and edge of field practices like saturated buffers and bioreactors. These combined practices are needed to achieve the nitrogen and phosphorus loss goals of the Iowa Nutrient Reduction Strategy. This strategy calls for a 45% reduction in total nitrogen and phosphorus loads going into Iowa waters, with 41% and 29% reductions in nitrogen and phosphorus loads, respectively, from non-point sources, such as agricultural production.
The 4R Plus program began in 2016 by bringing diverse organizations together to create an outreach campaign to help inform Iowa farmers about the suite of conservation practices available to them. To date, more than 40 organizations have enlisted their support of the Iowa 4R Plus program, including agri-businesses, commodity groups, trade associations, government agencies, conservation organizations, Iowa State University and Iowa Learning Farms.
To kick off the project, market research was conducted with Iowa farmers and Certified Crop Advisers (CCAs) to help understand what practices they were using, key messages that resonated with them, barriers that hindered them from trying new practices and what their plans were for adopting new practices in the future. The results showed that messages that resonated the strongest with farmers centered on 1) the role of healthy soil in addressing more extreme precipitation patterns, and 2) the importance of passing the farm to the next generation in better shape than they received it. The market research also verified the importance of CCAs as the trusted adviser to farmers.
With the market research results in hand, 4R Plus coalition members developed 4R Plus informational resources that they could leverage with their internal and external stakeholders, including CCAs and farmers. The resources include a 4R Plus brochure, 4R Plus Fact Sheet, a website (4rplus.org/), 4R Plus Blogs, an adviser module and a Twitter account (@4RPlus). Most recently, a series of five videos were released that describe Conservation Practices, the 4Rs of Nutrient Stewardship and the Iowa Nutrient Reduction Strategy. In addition, the five videos were converted into courses for CCAs to take for Continuing Education Units (i.e. credits). The CCA courses can be found at 4R Plus CCA Courses.
In addition to the 4R Plus resources mentioned above, the 4R Plus program has a communications and outreach component at the state level that includes radio, print and digital media. In 2018, these media platforms are delivering 4R Plus messages to 85-90% of Iowa farmers.
The 4R Plus program is an exciting new effort to bring information about nutrient management and conservation practices to the Iowa farming community in a straight-forward and factual way. The partners are committed to helping farmers implement practices that fit their unique individual operations and provide economic, agronomic, environmental and societal benefits on their farm and to their downstream neighbors.
