Twenty years ago, Peter Harper remembers farmers complaining about how hard it was to establish productive and persistent perennial lucerne pastures; these days the challenge is trying to kill them in preparation for the cropping phase. Peter and his family have been managing the challenge of optimal establishment in their mixed farming system for the past 20 years and have recently worked alongside the FFI CRC EverCrop team to fine tune their cover cropping approach.
- Cover cropping (under-sowing crops with perennial pasture in the year of establishment) can be cost-effective, but success is seasonally dependent.
- The benefits of cover cropping in a mixed farming system go further than crop or pasture production alone.
- Achieving the right balance of crop and pasture sowing rates, under favourable seasonal conditions, boosts the chance of success.
