Tall fescue (turf -type)** 130 to 170 lbs. 5.6 to 7.5 +bluegrass 20 to 30 tbs. CHANNELS AND AREAS OF CONCENTRATED FLOW 1. Perennial ryegrass 100 to 150 lbs. 5.6 to 7.0 +white or ladino clover* 1 to 2 tbs. 2.

Tall fescue** 100 to 150 lbs. 5.5 to 7.5 + Perennial ryegrass 15 to 20 tbs. + Kentucky bluegrass 15 to 20 tbs. * For best results: (a) legume seed should be inoculated; (b) seeding mixtures containing legumes should pref- erably be spring -seeded, although the grass may be fall -seeded and the legume frosWeeded (Practice 3.13); and (c) if legumes are fall -seeded do so in early fall. ** Tall fmcue provides little cover for, and may be toxic to, some species of wildlife. The IDNR recognizes the need for additional research on alternatives to tall fescue, such as buffalograss, orchard -grass, smooth brome- grass, and switch -grass. This research, in conjunction with demonstration oreas, should focus on erosion control characteristics, wildlife toxicity, turf durability, and drought resistance. NOTE. An oat or wheat companion or nurse crop may be used with any of the above permanent seeding mixtures. If so, it is best to seed during the fall seeding period, es- pecially after Sept. 15, and at the following rates., sprint oats-114 to 314 bu./acre; wheat -no more than 112 bu./acre.
