Fertilization

For many field crops fertilizer input choices are among the most important determinant of profitability. From an environmental perspective these choices can also be problematic because high application rates in combination with adverse weather outcomes can lead to impaired waterways. There is high demand for an understanding of relationships between determinants of fertilizer application choices on the one hand and environmental outcomes on the other hand. Unfortunately, public on field-level fertilizer choices are limited. Agricultural economists often recourse to University and other public sector fertilizer trial data where kindly made available by agronomy researchers. The ERS chair occupant has worked with fertilizer choices in corn-soybean rotations.

Discussions on these papers can be found under other website headings. Work is not currently ongoing in the area but remote sensing and other information technologies are opening up possibilities and if anyone out there has an interest in the area for research and outreach purposes then feel free to email hennes64@msu.edu.
