See the pros and cons of different fertilization methods for citrus as shared by the UF/IFAS commercial fruit crop agent for Lake and Orange counties.
When it comes to fertilization methods for citrus, growers have a few different options. The advantages and disadvantages of those options were shared by Brandon White, a biological scientist and the commercial fruit crop agent for Lake and Orange counties, at the Citrus Nutrition Day in October. The details were shared in a Citrus Industry article. See them below.
Fertilization Methods for Citrus
The following are soil-based fertilization methods for citrus:
Soil-applied methods utilizing granular (dry) fertilizer. Traditional soil-applied granular fertilization is applied to the soil.
- It is inexpensive
- The nutrients are readily available to the plant
- It is subject to leaching
- Multiple applications increase labor and costs
Controlled-release fertilizer (CRF). A soil-applied granular fertilization that is formulated to release small amounts of fertilizer over time.
- It gives the tree a constant supply of nutrients
- It requires fewer applications than other fertilization methods
- It is expensive
Fertigation. This is the application of liquid fertilizer though an irrigation system.
- It is relatively inexpensive,
- It offers flexibility in application
- It provides a constant nutrient supply in small doses
- It is high maintenance, requiring a cleaning and flushing plan
- It is not suitable for all nutrients
The following is a foliar-applied method:
Foliar-applied fertilization. This is where nutrients are applied to the leaves in a citrus tree’s canopy.
- It is the quickest fertilization method
- It allows growers to assist trees during times of high demand or other hindering conditions such as wet, dry or cold weather
- A foliar nutrition program must be coupled with a soil nutrition program and that it causes leaf burn when not applied at the correct time
