Relationship Between NO3-N Production, Dry-Matter Production and N Responses on Coastal Plain Soils1
- C. D. Welch and
- W. V. Bartholomew2
Nitrate-N production appeared to give a better estimate of the availability of soil N than Kjeldahl N or organic matter. Higher correlation coefficients were obtained for data from well-drained than from poorly drained soils. Comparisons between results for organic matter or Kjeldahl N and corn yield responses from N applications under field conditions were not significant.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
