Fertilizer and irrigation effects on the growth of potted citrus nursery trees

摘要

Huanglongbing (HLB, or "greening") and canker diseases have substantially affected Florida's citrus industry in the past decade. After their appearances, statewide guidelines were implemented to stop any additional spreading of HLB and canker. One such effort is a mandate that all commercial citrus nurseries in the state have to grow young trees in completely enclosed greenhouses. This mandate is part of the Citrus Nursery Stock Certification Program, and is described in detail as the Florida Department of Agriculture's rule 5B-62. The rule has dramatically changed how citrus nurserymen cultivate young trees in the state.
