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).

Challenge #2: Reduced Water Quality

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: Read more about Challenge #2: Reduced Water Quality
