I work for a Land Development company in the greater DSM metro area and we want to establish diverse native prairie in development outlots which largely include ponds and stormwater basins. We often have 1:4 slopes. I'm wanting feedback on best way to seed diverse mixes on these slopes. Our plan right now is to establish a cover crop on the slopes of oats/annual rye for the summer then interseed into it with minimal disturbance during the dormant window (hopefully January/February). Should we use a native seed drill like a Truax, or are we better off broadcasting? Should we mow the cover crop prior to seeding or will that cause issues with seed-to-soil contact? I'm hoping I can connect with someone who has had good success with establishment on common development slopes while maintaining compliance with the requirements of the storm water pollution prevention plan and erosion.
