Agronomic Soil Test — LTAR Aspirational Cropping System Experiment (ACSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
LTAR agronomic soil chemistry data. These samples are generally taken to generate fertilizer recommendations. In 2021 the samples were analyzed by the MSU Soil Fertility lab. Later samples were analyzed at the AL Great Lakes Lab.
This datatable is part of the LTAR soil datasets dataset.
This dataset contains the soil data from the KBS LTAR experiment.
