Here's what I do:
1. Get a soil sample in March, takes about 6 weeks to process
2. Mow and kill all vegetation in plot around June.
3. Apply required amount of lime July, disc or till into soil
4. If needed mow and kill weeds again first of September
5. Couple weeks later with rain in the forecast, thoroughly disc field, drag smooth, apply fertilizer
6. Spread oats, and winter rye, drag field again.
7. Spread clover and rape on top of smooth soil bed.
8. Pray for rain and no hurricanes.
