Abstract
A gasifier residue evaluated in combination with Canadian sphagnum peat moss (P), coarse sand (S), and/or pine bark (B) produced no deficiency or toxicity symptoms when used as a container media component for growth of Rhododendron cv. Redwing, Buxus microphylla Siebold and Zucc. var. Japonica, and Juniperus horizontalis Moench cv. Plumosa. Compared to the standard BPS, the BRS and BPR media yielded a larger boxwood. Juniper and azalea growth responses were similar on BPS and BRS. The present cost of the BRS medium is less than 1/3 that of the standard BPS medium.
Abstract
The physical and water-release characteristics of a gasifier residue in combination with bark, Canadian sphagnum peat, and sand were determined. Both gasifier residue and peat had characteristics more favorable for plant growth than bark or sand alone. The combination of gasifier residue and peat produced characteristics superior to gasifier residue or peat alone. Gasifier residue and combinations of gasifier residue and peat had almost twice the available water of a standard nursery medium. The addition of sand or bark decreased the performance of gasifier residue in a number of physical parameters. Unsieved gasifier residue had a particle size distribution suitable for container plant production.
