Soilless substrates used in U.S. floriculture are comprised primarily of sphagnum peatmoss amended with perlite, vermiculite, pumice, and to a lesser extent sand, compost, and other components. Sphagnum peatmoss does not contain sufficient

Recently, urea–formaldehyde resin foam (UFRF) has been introduced as a synthetic organic soil amendment and is used as a substrate in the propagation and growth of plants in hydroponic systems, soilless cultures, and substrates used in production of

environmentally friendly substrates with good quality, low cost, and obtainable in great quantity is attracting more attention. Recently, several formulations of alternative materials for potting ornamental plants are being developed, in particular for herbaceous

Horticultural container substrates generally yield complex pore geometries spanning interparticle and intraparticle voids ( Bartley et al., 2019 ). Intraparticle pores can be active or inactive contributors to gas and water exchanges relative to

addition, the utilization of biochar improved the quality of the soil because of its sorption qualities that helped to retain nutrients and nitrogen ( Ippolito et al., 2012 ). The components of horticultural substrates used in commercial greenhouse and

The primary component in greenhouse potting substrates is sphagnum peatmoss. Substrate solution pH of nonamended peatmoss ranges from 4.0 to 4.5 ( Landis, 1990 ). Optimum substrate pH has been determined for economically important crops such as

During the 1980s, many geranium producers observed a sporadic, unexplained decline in substrate pH. During the same time period, they also reported the occurrence of toxic concentrations of Fe or Mn in leaf tissue ( Bachman and Miller, 1995 ). In
