Long-Term Soil Ecosystem Studies

The Missouri LTSP Study is comprised of thirty plots. There are three plots per treatment, in addition to three control plots. Within the study, there are three levels of organic matter (OM) removal and three levels of soil compaction (C). In addition to these effects, each of the non-control plots are sub-divided by competition control. Competition on the north half of all plots is controlled using chemical herbicides. After the treatments were applied to the site, shortleaf pine, northern red oak, and white oak seedlings were planted on the treatment plots.
