Experiment 070 - Legume Competition Garden

This experiment was established on top of subplots 24, 25 and 26 of E055 (1.2m X 1.2m plots). Sheet metal was installed to divide the subplots into 4 equal parts (subplots are 1.2m x 1.2m, sub-subplots are .6m x .6m). The resulting 12 sub-subplots (4/subplot = 12/plot) were planted according to the following treatments:

1. LC seed on top of established SS

2. AC seed on top of established SS

3. no seed added to established SS

4. PP seed on top of established SS

5. AC seed vs SS seed

6. LC seed vs SS seed

7. PP seed vs SS seed

8. LC seed vs AC seed vs PP seed vs SS seed

9. AC seed

10. LC seed

11. Bare ground (no seeds added)

12. PP seed

Where LC=Lespedeza capitata, AC=Amorpha canescens, PP=Petalostemum purpureum, and SS=Schizachyrium scoparium. Equal amounts of MgSO4, CaCO3, P2O5 and K2O are added to the plots each year in early May and Late June. For further information, see fertilization details.
