Download a ISU Extension report on how targeting key portions of row-crop fields to perennial vegetation can lead to dramatic improvements in environmental benefits on farmland:
STRIPS Farmer Liaison presents on "Spreading Prairie to Iowa Farms" in this recent Iowa Learning Farms webinar. Tim is the best person on the team to ask questions of when it comes to on-farm implementation of prairie strips.
Students will be able to:
- Explain challenges facing Midwestern farmers.
- Define and explain the prairie STRIPS project.
- Explain the agronomic benefits of prairie strips.
- Recommend key features of prairie strip designs.
- Identify characteristics of prairie plant species which makes them useful conservation devices.
- Describe appropriate prairie strip installation and establishment procedures.
Challenge #2: Reduced Water Quality
Nutrients such as nitrogen and phosphorus, and suspended soil sediments have greatly diminished water quality (USEPA, 2017a). Polluted water with unusually high concentrations of dissolved or suspended materials, or small amounts of highly toxic materials can be detrimental and sometimes even deadly to living things. Civilization has many uses for and is dependent on high-quality water (Troeh et al., 2004).
Major agricultural contributions to reduced water quality include:
Iowa Nutrient Reduction Strategy
“The Iowa Nutrient Reduction Strategy is a science and technology-based framework to assess and reduce nutrients to Iowa waters and the Gulf of Mexico. It is designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable and cost effective manner” (ISU, 2017b).
