Soil Inorganic Nitrogen by Treatment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Soil nitrate and ammonium values averaged by treatment. This dataset is derived from the Soil Nitrate and Ammonium datatable.

This datatable is part of the Soil Inorganic Nitrogen on the Main Cropping System Experiment dataset. Measurement of soil inorganic nitrogen began in 1989 for all treatments on the LTER Main Site and 1993 on the Successional and Forest sites. Ammonium and nitrate are analyzed twice monthly or monthly during the growing season on baseline soil samplings. Additional datasets from the Baseline Soil Samplings include soil moisture, total N and total C.
