Macadamia is a long-term industrial crop with high economic value thanks to its nutrient-rich nuts and stable market demand. To achieve high productivity and uniform nut quality, implementing an automatic irrigation system is an essential trend in modern macadamia farming. The choice of irrigation technique depends on local climate, soil conditions, planting density, and available water sources.
Although macadamia trees are moderately drought-tolerant, stable growth and fruiting—especially during establishment and flowering/fruit-setting stages—require timely and adequate irrigation.
Best applied in: Hilly areas, basaltic soils, arid climates.
Benefits:
Saves water, allows precise fertilizer application via fertigation.
Maintains consistent moisture around the root zone.
Minimizes weeds and fungal diseases.
Easily automated to reduce labor and improve orchard management efficiency.
Best applied in: Young plantations or areas with wide planting spacing.
Notes:
Avoid wide-area spraying to reduce water waste and fungal disease risk.
Suitable for small-scale models or areas with accessible water.
Use early morning or late afternoon to minimize evaporation.
Establishment Phase (1–3 years): Combine drip irrigation with mulch (straw, dry grass, or agricultural film) to conserve moisture, reduce weeds, and prevent erosion.
Flowering & Fruit Setting Stage: Maintain stable moisture. Water stress may cause flower drop or low nut set rate.
Pro tip: Apply fertilizers periodically through drip lines to ensure even and efficient nutrient absorption.
A standard drip irrigation system includes: Water source → Filtration unit → Main & submain pipelines → Drip lines around the tree base.
Each tree typically has 1–2 drip rings depending on age and canopy width.
Fertilizer injection can be integrated (fertigation).
Ideal for industrial plantations of several hectares and more.
Use micro-sprinklers with a radius of 0.5–1.5m.
Adjust flow rate to match tree age and growth stage.
Requires good drainage design, especially during rainy seasons to prevent root rot.
Young trees (1–2 years): Water every 2–3 days during dry periods. Drip irrigation is preferred.
Flowering & Fruiting: Keep moisture stable to prevent sudden drought stress and premature fruit drop.
Pre-harvest: Gradually reduce watering to harden nuts, improve quality, and extend shelf life.
Driptec dripline is the Thin-wall dripline with some outstanding features such as diverse thickness, emitter spacing and flow rate. Especially the driplines are produced on modern, highly automated technological lines, quality has been verified for more than 10 years in the Vietnamese market.

General information
The cost of an automatic irrigation system for macadamia cultivation projects varies depending on factors such as planting specifications and density, farm size, terrain conditions, water source location, and whether an electric or diesel pump is used.
