Annual Reports

Commodities

  • Agronomic: corn

Practices

  • Crop Production: cover crops, no-till, nutrient cycling
  • Production Systems: general crop production
  • Soil Management: nutrient mineralization

    Abstract:

    This project was not completed. No Final Report available.

    Project objectives:

    For each cover crop a Nitrogen Fertilizer Equivalent (NFE)value will be determined. That is, the amount of N that was taken up in the cover crop and made available through mineralization to the following corn crop. This NFE will be compared to the fiber tests of the cover crops to determine the extent of the relationship between fiber content and NFE.
