Methods of Constructing a Pine Tree Substrate Potting Medium from Various Wood Particle Sizes and Organic Amendments
Producing PTS medium using hammermill and amendments
Research showing the successful use of pine tree substrates (PTS) produced by grinding loblolly pine trees (Pinus taeda) has gained considerable interest from growers and substrate manufacturers. This research has shown that a PTS can be used to produce a wide variety of nursery and greenhouse crops. Some advantages to PTS are:(1) that PTS can be produced in close proximity to growers where pine trees are available and (2) physical properties such as container capacity (CC) and air space (AS) can be easily altered to meet the needs of particular plants and container sizes by the degree of grinding of the pine wood chips in a hammermill.
