Document Summary

Forage crop establishment; sodseeding/ no-tillage planting: crop establishment vs. stand renovation, crop establishment, starting from scratch, creating a hayfield, pasture, or silage crop, stand renovation: Improving an existing stand: changing composition (density, species, adding legumes to a (primarily) grass stand. Insect control: potential severity of insect damage varies w/ crop and cropping history, alfalfa, crop rotation, previous insect pops, sodseeding vs stand establishment (clean seedbed) If lodging occurs, remove companion crop immediately: avoid n applications. Importance of soil moisture at planting (no-till: a no-till drill opens a slit in the soil with a disc or narrow shovel, the seed is then dropped into the slit and press wheels close the slit. If the soil is too wet, the slit does not close, resulting in poor seed-to-soil contact. Interseeding: no-till seeding, common sodseeding situations, establishment of legumes into perennial, cool-season grass sod, establishment of annual, cool-season grasses &/or legumes into perennial, warm-season grasses.
