Efficient watering for high-value crops

Horticulture crops perform best with close, uniform wetting. Drip lines with correct emitter spacing and stable pressure deliver consistent yields while saving water.

Emitter spacing examples

• Tomatoes: 20–30 cm between emitters (double-line layouts common)
• Leafy greens: 15–25 cm for frequent wetting and shallow roots
• Onions/shallots: 20–30 cm depending on bed width

Key recommendations

• Use pressure-compensating emitters for long runs or slopes
• Zone by crop type and bed length to match run times
• Filter water carefully to avoid emitter clogging
• Check pressure at the farthest emitter during commissioning

Bed layouts

Plan laterals along beds with emitters placed to match crop rows. Raised beds may need split laterals for even distribution.

Flow considerations

Calculate flow per bed based on emitter rate and number of emitters to size mainlines and pump capacity correctly.

Maintenance

Flush laterals, clean filters and inspect emitters frequently during the season to avoid uneven watering.
