Fractionation of Nitrogen in Three Forest Soils
- J. R. Jorgensen
Soil nitrogen of forested Georgeville, Colfax, and Iredell soils from the North Carolina Piedmont was separated into six fractions. Amino acid N made up over 50% of soil N, while hydrolyzed NH4+ + amino sugar-N was 22% of the total N. Proportions of exchangeable NH4+ + NO3−, insoluble humin N, and hydrolyzed NH4+ + amino sugar N differed with soil. The differences appeared to be related to base saturation and pH.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
