Abstract:
The continuous agricultural soil monitoring program (BDF) by the Saxon State Office for Environment, Agriculture, and Geology (LfULG) is operational since 1995, collecting and analysing samples periodically from 60 monitoring sites across Saxony, Germany. Stepped thermal analysis allows for the fast and cost-effective determination of different carbon fractions of ground soil samples. This dataset reports the analysis of 902 archive samples from the Soil Monitoring Program of the State Office for Environment, Agriculture, and Geology (LfULG) collected between 1995 and 2023, and 462 samples collected during a sampling campaign in September 2023. We report the thermal soil carbon fractions TOC400, ROC (ROC600), and TIC900 measured in air-dried and ground samples according to DIN19539 / DIN EN 17505 using an Elementar soliTOC cube. This dataset is part of a mid-infrared soil spectral library for agricultural soils in Saxony, Germany.

Comment:
L: Soil pit sample
A, B, C: Area sample replicates; At each BDF sampling campaign, 3 mixed samples (from respective 6 individual sampling points) are collected
P, M : test sample, mixed sample (for archive samples)
Profil: Soil pit sample of the field sampling campaign
Y00: Area sample along axis Y in distance 00 [m] from soil pit; Orthogonal to X
X00: Area sample along axis X in distance 00 [m] from soil pit; Orthogonal to Y
P1, P2, P3: At BDF23 sampling with the quicksampler was not possible due to high abundance of coarse fraction; Replaced with 3 push cores in close proximity to soil pit
