Improving nitrogen and phosphorus use efficiency of potted chrysanthemums grown in a subirrigation system

Regardless of the irrigation system used in greenhouse floricultural operations, nutrient delivery should be optimized so that a lower level of fertilizer is used over the crop cycle, thereby minimizing fertilizer costs and environmental impacts. This novel and innovative approach calls for a constant lower level of nutrients to be delivered during vegetative growth only, and this lower level was optimized so that reproductive growth was primarily sustained by the mobilization of previously-acquired nutrients, rather than current supply from the root system.
