| Abstract:
Nutrient concentrations and pH in the root zone of container-grown ornamental plants in peat-based media are determined by the irrigation water quality and method, root medium, fertilizer and how these factors are managed. Based on more than 50 experiments completed over a ten year period the effects and interactions of irrigation and leaching methods, the incorporation of preplant fertilizers and lime, the root medium water holding capacity, the irrigation water quality, the water soluble fertilizer reaction and balance, the root medium chemical properties and the plant species on the root zone nutrient status and pH are presented. Also discussed are a simple model for nitrogen flow in a subirrigated container medium, a nondestructive root medium extraction method, and petiole nitrate analysis of bedding and flowering potted plants. | |
