Forage EstablishmentJean-Marie LuginbuhlNC STATE UNIVERSITY 15. Soil Testing is Key Test 6 months before establishment Gives you time to apply lime Grasses need pH 5.8-6.3 Legumes prefer pH 6.0-6.5 Some forages like lespedeza grow well in low fertile soils Phosphorus (P) and Potassium (K) can be incorporated into soil before planting needed for legumes 16. Establishment failures caused by: Poor seedbed preparation Incorrect seed depth Incorrect planting date Pests (weeds, insects, diseases) Soil/plant incompatibility Stress factors (drought) Herbicide carry over Incorrect seeding rate Poor germination 17. Establishment issues 18. Excellent stand 19. Spraying Round-up 20. No-till drill planting into existing sod 21. Prepared seedbed 22. Prepare a smooth, firm seedbed to drill seedsThese seedbeds are firm and have no large hard clods. The shoe impression did not sink into the soil (firm) yet it made a clear impression. Your footprint should never go deeper than For a sandy soil, more small clods would be desirable to inhibit wind erosion.When you plant onto soft soil, the seeds will go too deep and never break through the soil 23. www.forages.ncsu.edu Tech. Bull. 305, Chap 11Broadcasting seeds Seeding rates are 25-50% higher than drilling Lower soil-seed contact Run over field with cultipacker, drag, animal hooves 24. Cultipackers 25. Seeding Depth is CriticalSoil level - Small seeds like legumesGrass seeds 1-2Plant seeds a little bit deeper in sandy soils because of moisture stressLarge seeds like corn, millet, sudangrass 26. Establishing Warm Season Annuals Plant Pearlmillet, Sorghumsudan hybrids, Sudangrass, Soybeans, Cowpea, Crabgrass, Sun Hemp in late April early May Earlier = less weed competition Apply N to grasses Graze June Aug/Sept 27. Establishing Warm Season Perennials Plant Sericea Lespedeza Late February Early March Plant Bluestem, Gamagrass, Switchgrass - March/April Graze May Aug (not during year of establishment) Plant into a fallow field or winter annual field grazed down Bermudagrass sprigs March Bermudagrass seeds April/May 28. Establishing Cool Season Grasses Tall Fescue, Orchardgrass Ideally plant in Sept 1 Oct 15 Insect problems army worms, grasshoppers Kill existing sod 2 weeks prior No till drill into a thin stand Planting too late = freezing Plants need 3-4 leaves before frost Fertilize with N or add clovers 29. Establishing Cool Season Grasses Tall Fescue, Orchardgrass Plant in March Problems with annual weeds (mow) Plant early so seedlings can handle summer heat and drought Kill sod the previous fall Plant a winter annual prior to spring planting 30. Establishing Legumes 30% mix of legumes in cool-season pastures can replace 150 lb N/yr/acre Sow clovers (ladino, crimson, red, others) Sept-Oct Possibly band spray roundup before fall planting of clovers Frost seed clovers in late winter (Feb-March) Plant Austrian winter pea, vetches in Sept Oct Alfalfa - Sept-Oct 31. Establishing Legumes If you drill into fescue sod make sure stubble is
