Influence of irrigation method, fertilization rate, and media type on growth of Quercus rubra container grown seedlings.
Water use by the agricultural and horticultural industries has become a major concern in recent years with a high level of water consumption through irrigation and excessive waste water produced. One proposed solution for mitigation of this problem in plant nurseries is sub-irrigation, a watering technique where irrigation is supplied to plants from below and nutrients and nutrients and water are recycled throughout the system. This study examines using sub-irrigation during propagation of forest tree seedlings to reduce water consumption and waste water output. Quercus rubra L. seedlings were grown with sub-irrigation and overhead watering in a partially controlled environment greenhouse. Three media types and three nutritional rates were compared to evaluate growth, media electrical conductivity levels, and nutrient leachate concentrations in waste water. Results presented will identify differences between growth rates, nutrient content, and other basic growth parameters. Initial results indicate a few differences between irrigation treatments, significant differences between nutritional rates, and some differences between media type treatments. Sub-irrigation can be an effective replacement of traditional container watering systems which could have a significant impact on forest container seedling production in the future.
