Drip Irrigation
for Pangasinan Farms

Pangasinan is one of Northern Luzon's most geographically diverse agricultural provinces, stretching from the Lingayen Gulf coastline through the Agno River valley to the inland hills and uplands of the eastern municipalities. The province is famous for bangus (milkfish) aquaculture, but its agricultural sector is equally significant: mango orchards thrive in the drier inland areas around Urdaneta and San Carlos, vegetable farms dot the river valley, and rice remains a staple crop across the flatlands. Salt production along the coast and a growing interest in high-value crop diversification are pushing Pangasinan agriculture toward modernization.

The central water challenge in Pangasinan is the stark contrast between its coastal and inland environments. Coastal farms near Dagupan, Lingayen, and Binmaley contend with sandy soil that drains too quickly and, in some areas, saltwater intrusion into shallow aquifers that makes well water unusable for sensitive crops. Inland farms have better soil but face severe dry-season water stress when the Agno River flow drops and the San Roque Dam prioritizes power generation over agricultural releases. Deep wells in the interior can reach clean freshwater, but pumping costs eat into farm margins, especially for crops irrigated by inefficient flood methods.

Drip irrigation resolves these issues from both directions. For coastal farms, closely spaced emitters running in short cycles keep moisture available in fast-draining sandy soil, while controlled application rates prevent salt accumulation in the root zone. For inland mango orchards, drip tubing with pressure-compensating emitters delivers consistent moisture during the critical flowering period from January to March, when even a brief dry spell can cause flower drop and drastically reduce fruit set. Vegetable farmers along the Agno valley find that drip systems stretch their dry-season water supply two to three times further than furrow irrigation, turning a marginal growing season into a reliably profitable one. For Pangasinan's commercial mango growers in particular, drip irrigation combined with fertigation has proven to be one of the most effective investments for improving fruit size, sweetness, and market value.
