- Agronomic: corn, oats, spelt, soybeans, wheat, grass (misc. perennial), hay
- Vegetables: beans
- Animal Production: feed/forage
- Crop Production: nutrient cycling
- Soil Management: organic matter, soil analysis, nutrient mineralization, soil quality/health
This continues FNE99-264, and explores further the trends in soil nutrient status into a second year. The project is examining the seasonal fluctuations in nutrient levels, and explores the question of whether soil test results may need to be calibrated for variables such as time of year, stage of crop growth, and seasonal events such as drought or excessive rain.
