Agronomic Yields of Annual Crops — Interactions 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 from harvested annual crops of the Interactions Experiment until retirement after the 2015 growing season. Note that yields are reported at standard moisture and need to be converted if dry mass units are needed.

This datatable is part of the Interactions Experiment dataset.

This dataset contains data from the Interactions Experiment established in 1985 that examined the interactive effects of tillage (conventional (CT) and no tillage (NT)) and fertilization (fertilized (F) and not-fertilized (NF)) on crop production. The experimental site contained two areas that differed in prior land use: one site was historically tilled (plots 1-16) and the other has never been tilled (plots 17-24). All cropped plots (all plots except the Reference plots) were originally planted to continuous corn and switched to the same corn-soybean-wheat rotation as the LTER Main Cropping System Experiment (MCSE) around 2001. The historically tilled portion of the experiment was discontinued after the 2015 harvest and 2016 conversion to switchgrass. The experiment continues in the never tilled plots including the cropped plots (T8nt; 17, 20, 21, and 24) which follow the rotation and management of the MCSE No-till (T2) treatment and the reference plots (T8; 18, 19, 22, and 23) which are maintained as the MCSE Mown Grassland (T8) treatment. T8 and T8nt data are found in MCSE datasets.
