Many economic and policy factors influence the adoption of organic and chemical nutrient management practices and technologies, as well as the economic and environmental implications of that adoption. Research assesses the extent of adoption for such nutrient management strategies as soil testing, crop rotation, nitrogen inhibitors, the use of manure, fertilizer application method and timing, and precision agriculture.

Crop Production Practices—Phase II of the Agricultural Resource Management Survey (ARMS) is USDA’s primary source of information about the current status and trends in crop production practices for major crops (corn, soybeans, wheat, and cotton). This survey also obtains data on U.S. farmers' agricultural resource use, as well as data to assess potential environmental impacts associated with crop production practices. The ARMS survey yields annual data summaries for field-level data by crop, including: irrigation technology and water use, nutrient use and nutrient management practices, crop residue management practices, pest management practices and pesticide use, and crop seed variety. Data summaries are available for production years 1996-2000 (1996-98 and 2000 for wheat).(1/03)
