Converting mature citrus from full cover to drip irrigation
Summary
Drip irrigation is a popular method of water application for citrus growers, particularly in new developments, but also when converting established plantings. Converting mature citrus trees to drip irrigation creates a series of challenges that can be overcome if appropriate management practices are adopted. Where an established orchard is converted to drip, the change in wetting pattern can ‘shock’ the tree and result in poor tree health and reduced productivity in the first year after conversion. However, converting existing trees can be successful if growers follow a few simple guidelines.
Topics include:
- Rootstock
- Existing orchard health
- Soil
- Nematodes and Phytophthora
- Irrigation management in the first season
- Fertigation
- Irrigation scheduling
- Dual systems
- Dripline location
- Timing the conversion
- Using existing pipework
