John Innes compost
John Innes compost is a set of four formulae for growing medium, developed at the John Innes Centre in the 1930s and released into the public domain. The formulae contain loam, peat, sand or grit, and fertiliser in varying ratios for specific purposes.
The composts are "soil-based".
