KBS LTER MCSE

All 11 treatment plots are assigned to a ~1 ha plot in 1 of 6 replicate blocks for the main site complex (87m x 105m) and 1 of 3 or 4 replicate blocks in off-site forest and successional treatment plots. Each plot also contains a permanent set of 5 sampling stations at which most within-plot sampling is performed.
 
The four annual ecosystems are corn – soybean – winter wheat rotations managed using:
(i) Conventional chemical inputs and tillage
(ii) Conventional chemical inputs and no-tillage
(iii) Reduced chemical inputs, and
(iv) No chemical inputs, i.e., biologically.
 
The latter two treatments include winter cover crops: red clover inter-seeded in the spring into the wheat phase of the rotation prior to corn, and annual rye planted following corn harvest prior to soybeans.
 
The three herbaceous and woody perennial ecosystems are:0
(i) Alfalfa
(ii) Poplar clones, and
(iii) Coniferous forest plantation.

The four successional ecosystems with herbaceous and woody perennial vegetation are:
(i) Early successional ecosystem (abandoned from agriculture 1989; periodically burned after 1996)
(ii) Never-tilled grassland (herbaceous perennial vegetation mown annually)
(iii) Mid-successional ecosystem (herbaceous annual and woody perennial vegetation)
(iv) Deciduous forest (woody perennial vegetation)
