The availability of organic components of potting media is limited due to supply and shipping costs. Disposal of solid waste has also become a serious problem for many municipalities. The utilization of solid waste compost in agricultural production promises to be a solution for both concerns. The objective of this experiment was to determine the efficacy of sol id waste compost from Miami, Dade County, Florida as a propagation medium for vegetative reproduction of ornamental and landscape plants.

Cuttings of Podocarpus macrophylla, Chrysobalanus icaro, and Impatiens spp. 1-13 cm long, treated with .2% NAA ppm IBA were rooted in media composed of sphagnum peatmoss: perlite (1:1) or Agrisoil (TM) solid waste compost: perlite (1:). Cutting rooted well in both media. Data included number of roots and root weight.

Many pesticide labels contain rate recommendations in units that are not readily pertinent to container nursery production situations.

A program is presented, in the RPN programming language, for the conversion of pesticide rate terms from lb per ft2 to grams per container: f LBL A, RCL 2, ENTER, 1, 4, 4, X, STO 5, RCL 3, ENTER, 2, ENTER, g X2, f, X, STO 4, RCL 1, 4, 5, 3, ·, 9, X, STO 9, RCL 9, ENTER, RCL 9, ENTER, RCL 4, X, RCL 5,, g RTN.

Use of this program allows precise conversions of agricultural chemical application rates for container grown horticultural crops.
