Based on earlier research results which pointed to the negative impact of compacted urban soils, this research project was designed to improve tree survivability in highway and urban environments. After five years of research and four years of direct testing, deep ripping and the addition of organic matter has been proven as a method of remediation of urban soils to ensure the long-term survival of trees. Based on several sites sampled throughout Ontario and Alberta, a soil remediation calculator was developed that estimates the amount of organic amendment required to bring the soil bulk density below root limiting thresholds for trees
A literature review on post harvest treatments of nursery stock has identified a significant lack of fundamental information about root storage and basic plant physiology. A set of small-scale experiments was undertaken to answer some of these basic questions and lay the groundwork for a future larger project.
A literature review was conducted and interviews with growers and water treatment companies to assemble information on available technologies. An interactive website will provide growers with an on-line decision process for choosing appropriate technology for their own operation.
Investigate biological and applied characteristics of the temperature relations within flowers and within plant stems through interdisciplinary research in micrometeorology, plant anatomy, pigmentation, microscopic morphology, growth rates, floral maturation and sexual reproduction.
La présence de cônes femelles dans les arbres de Noël est fortement dommageable pour la rentabilité de cette production. Les frais encourus pour éliminer manuellement les cônes sont très élevés. Quatre régulateurs de croissance ont été comparés à un témoin traité à l’eau. Les produits commerciaux étaient : Apogee, MaxCel, Fruitone, Bonzi, appliqués en pulvérisation foliaire et par injection dans le tronc. Les données supplémentaires recueillies au cours de ce projet n’ont pas permis d’identifier un régulateur de croissance permettant d’inhiber le développement des cônes femelles sur Abies fraseri cultivé en champ. Des travaux supplémentaires sont nécessaires pour mettre au point la méthode, notamment en ce qui concerne le moment de l’application, la dose du produit et la méthode d’application.

Five technologies were evaluated for their effectiveness at removing nutrients, non-nutrient components, and plant pathogens from irrigation runoff or leachate: a full scale constructed wetland system recently installed at a container nursery, and four pilot scale systems constructed at flower greenhouse: two denitrification woodchip bioreactors combined with phosphorus removal units, Phytolinks™ (floating wetlands), IrrigroTM irrigation system, and an engineered hollow fibre filter system (Zeeweed)Evaluation of innovative water treatment technologies for reuse of nutrient solutions in the horticulture industry
An in-field evaluation of the ability of 12 established denitrification woodchip bioreactors and constructed wetlands to remove plant pathogens and/or human enteric pathogen indicator organisms from horticultural and agricultural wastewaters and runoff was conducted. Removal effectiveness was correlated with parameters affecting performance (e.g. media, residence time, temperature, oxygen, pH, depth). The information supports the design of on-site systems that will consistently remove plant and enteric pathogens as well as nutrients from agricultural runoff and wastewaters in order to facilitate its reuse and/or protect surface and ground water resources from contamination
