Nitrogen Mineralization — GLBRC Biofuel Cropping System Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Potential nitrogen mineralization and nitrification rates measured 3 times over the 2013 growing season (early season, mid-season, and post-harvest) in main plots and alternative treatment subplots of BCSE treatments (G1-G10) by 28-day lab incubations. Rates are determined as the change in soil nitrate (plus nitrite) and ammonium over the incubation period.

This datatable is part of the GLBRC Soil Properties — Biofuel Cropping System Experiment dataset.

This dataset contains the chemical and physical properties of surface (0-25 cm) and deep (0-1 m) core soils of the GLBRC Biofuel Cropping System Experiment (BCSE).
