Chanthaburi · Rayong · Chumphon · Trat. Precision water and nutrient delivery that improves Monthong fruit weight, reduces disease, and cuts fertilizer waste — from 50 rai upward.

Thailand's durian export market is price-sensitive and grade-sensitive. Monthong buyers — whether domestic traders or Chinese exporters — pay a premium for large, consistent fruit. The difference between Grade A and Grade B is often just potassium delivery during weeks 8–14 of fruit development.
Sprinkler and flood systems deliver water to the canopy and topsoil surface. Durian roots are shallow (20–40 cm) and finely structured. Overhead watering encourages fungal disease at the trunk base and wastes fertilizer that washes past the root zone. Drip solves both problems at once.
Durian has five distinct physiological stages, each requiring a different water and nutrient profile. JJR's controller programs each stage automatically:
Controlled water stress to trigger uniform flower bud initiation. Drip allows precise withholding — impossible with sprinkler systems that inevitably deliver some moisture.
High phosphorus, moderate nitrogen. Drip delivers directly to the root zone without wetting flowers or causing fungal issues at the trunk collar.
Balanced N-P-K with calcium and magnesium. Consistent moisture prevents premature fruit drop — one of the most common losses in Thai orchards.
High potassium phase. This is where Monthong grade is determined. Drip delivers K precisely to the active root zone; broadcast fertilizer loses 40–60% before uptake.
Reduced irrigation to concentrate sugars and improve flesh texture. Drip allows controlled reduction that sprinkler systems cannot replicate.
| Metric | Sprinkler / Flood | JJR Drip Fertigation |
|---|---|---|
| Water delivery | Canopy + topsoil (high evaporation) | Root zone direct (minimal loss) |
| Fertilizer uptake | 40–55% | 85–92% |
| Trunk / collar disease risk | High (wet trunk base) | Low (no overhead wetting) |
| Fruit weight (Monthong) | Baseline | +15–25% average improvement |
| Dormancy induction control | Difficult (soil stays moist) | Precise controlled dry-down |
| Water use | Baseline | 30–50% reduction |
Thailand's largest durian province. Hilly terrain, reliable rainfall — drip for precise fertigation and dry-down control.
Significant Chinese-invested orchards. Mixed terrain, good road access for equipment delivery.
Southern expansion zone. Growing export volume, increasing demand for higher-grade fruit.
Border proximity to Cambodia. Thai and Chinese-operated orchards, export-focused production.
Q: My orchard is on a hillside — can drip work with uneven terrain?
Yes. JJR designs pressure-compensating drip systems for sloped terrain. Each emitter maintains consistent flow regardless of elevation change, which is critical on the hilly land typical of Chanthaburi and Chumphon.
Q: I already have a sprinkler system. Is it worth converting?
For orchards above 50 rai with active production, conversion typically pays back within 2–3 seasons through improved fruit grade and fertilizer savings. We can assess your existing infrastructure and advise on a phased conversion that minimises upfront cost.
Q: Can you supply equipment to Thailand and support installation?
Yes. JJR supplies equipment from China with full import documentation, and has installation support available through regional partners in Eastern Thailand. We can also train your existing farm team on system operation.
Q: Do you have references from Thai durian farms?
We have worked with Thai-operated and Chinese-invested durian orchards across Southeast Asia. We can provide specific project references during consultation. Contact us directly to discuss.
Tell us your province, orchard size, and current irrigation setup. We will advise on system design and expected ROI within 48 hours — no cost, no obligation.
