Why soil testing is not enough: A mixed methods study of farmer nutrient management decision-making among U.S....

Area of Science:

• Agricultural Science
• Environmental Science
• Social Science

Background:

• Minimizing nutrient loss to water resources is crucial.
• Farmer decision-making significantly impacts nutrient management.
• Understanding these decisions is key to improving water quality.

Purpose of the Study:

• To examine farmer decision-making regarding nutrient management (nitrogen and phosphorus).
• To identify factors influencing these decisions, including information sources and perceptions of water quality.
• To understand how regional contexts and farmer demographics affect choices.

Main Methods:

• Mixed-methods approach combining in-person interviews and quantitative surveys.
• Data collected from 105 farmers across Missouri, North Carolina, and Ohio (2015-2016).
• Analysis of decision-making processes, information consultation, and views on water quality.

Main Results:

• Farmers utilize diverse information sources: yield data, market prices, weather, experience, research, soil sampling, and social networks.
• Regional differences in support structures and perceived water problem severity influence decisions.
• Younger farmers are more open to improving practices than older farmers.

Conclusions:

• Tailoring educational programs to regional economic, social, and environmental contexts is essential.
• Farmer's past experiences and long-term knowledge shape their receptiveness to new interventions.
• Multifaceted approaches are needed to improve water quality through better nutrient management.
