Abstract
Description of Research Goals and Accomplishments: This experiment will test the affect of various species of seed addition and differing amounts of them on a newly abandoned area of the Lawrence strips. This experiment was set up in the northern end of the Lawrence strips after it was newly disked (no standing vegetation). There are 60 plots, each 3m x 3m with a .5m walkway between them. There are fifteen treatments, with 4 replicates of each treatment. The treatments are as follows, with the species of seed(s) and the amount added per plot: l. Ambrosia artemisiifolia, 90g 2. Agropyron repens, 67g 3. Poa pratensis, 45g 4. Schizachyrium scoparium, 67g 5. Andropogon gerardi, 67g 6. Mix of forbs, 50g 7. Mix 2 (see below) 8. Ambrosia artemisiifolia, 9g 9. Agropyron repens, 6.7g lO. Poa pratensis, 4.5g ll. Schizachyrium scoparium, 6.7g 12. Andropogon gerardi, 6.7g 13. Mix of forbs, 5g 14. Mix 3 (see below) 15. control-no seeds added Mix of forbs contains seeds of Achillea millefolium, Agastache foeniculum, Amorpha canescens, Aster azureus, Coreopsis palmata, Heliopsis helianthoides, Lespedeza capitata, Liatris aspera, Monarda fistulosa, Petalostemum candidum, Petalostemum purpureum, Rosa arkansana, Rudbeckia hirta, Solidago nemoralis, Solidago ptarmicoides, Solidago rigida, Verbena stricta and Zizia aurea. Mix 2 contains 50g Mix of forbs + 67g Schizachyrium scoparium + 67g Andropogon gerardi + 45g Poa pratensis + 90g Agropyron repens per plot. Mix 3 contains 5g Mix of forbs * 6.7g Schizachyrium scoparium + 6.7g Andropogon gerardi + 5g Poa pratensis + 9g Agropyron repens per plot. The seeds were added to the plots on June 14, 1993.
