SF 150 Field Fit is a premium Soil First™ cover crop mixture of Spring Oats, Soil First Select Radish and Turnips. A very simple cover crop mix that will completely winter kill in many northern climates. The turnips provide longer stay-green, allowing for extended nutrient capture (may even over-winter in Transition Zone and south and will need spring management). If sequestering leftover nutrients is the goal, this is the mix to use.
Planting window: 3-10 weeks before frost
- Seed 30-35 lbs/acre alone with a drill (7.5″ spacing)
- Broadcast/Aerial: 30-40 lbs/acre
- For forage 40-50 lbs/acre
Seeding depth: ¼” to 1″ deep
Comparable setting on drill chart: Oats (use large box)
Germination soil temperature: 45° F
DM tons/acre: 2-5
Considerations: Because of large percentage of oats, there is minimal lasting residue with Soil First® 150. If grazing, introduce Soil First® 150 slowly and don’t allow brassicas to ever make up more than 1/3 of livestock’s diet.

Termination: Radish will terminate with multiple nights in the teens. If radish over winter, glyphosate and 2,4-D provide effective control. Turnips might not winterkill in years with adequate snow cover (they need several days less than 20 degree F). Turnips, like radish, can be controlled with tillage or applications of paraquat, glyphosate and 2,4-D.
