Agronomic Yields — Biodiversity Gradient 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic yields of the Biodiversity Gradient Experiment measured before
the regular harvest by harvesting a subplot with a plot combine.
The experiment ended in 2019 and in 2020 the whole area was planted to sorghum to test
for residual effects.
This datatable is part of the Agronomic Yields on the Biodiversity Gradient Experiment dataset.
Agronomic yields have been measured on the Biodiversity Gradient Experiment since 2000. Samples are collected from the corn, soy and winter wheat plots before harvest by harvesting a subplot with a plot combine.
Initial soil moisture from the Biodiversity Gradient baseline sampling is also available for corn, soy and wheat plots.
