In May of 1979, eleven test plots were established to test the effectiveness of mulch and grass and legume mixtures. Test plots of hardwood bark, whole tree chips, straw, hay, five wood fiber products, one soil sealant and a control were established with five grass and legume seed mixtures. Bark and whole tree chips were applied at 45 ton/a, straw and hay at 1 1/2 ton/a, five wood fiber products at 1500 pound/a and the soil sealant at 5 gal/a. Seed mixtures were about 40 pounds/a. Bark and whole tree chips were found to promote the best total ground cover. Bark was also found to promote the best legume cover. Hay promoted the best grass cover. The best seed mixture consisted of 15 pounds/a KY-31 tall fescue, 8 pounds/a Gladiator Alfalfa, 6 pounds/a hulled Korean Lespedeza, 3 pounds/a Timfor Timothy and 6 pounds/a of Medium Red Clover. In general, the wood fiber products did not develop a better grass-legume stand than the control. The soil sealant was generally worse than the control.
