November marks the 12th Organic Agriculture Month, and the OA Tiangge is a simple way to support local farmers and food artisans
Looking for a way to celebrate Organic Agriculture Month? Visit the OA Tiangge in Quezon City. This four-day market opened on Nov. 9 at the Department of Agriculture (DA) Central Office. Over 20 exhibitors from around the Philippines are selling organic and natural products. You can taste, shop, and talk to the people who grow your food.

Why Does Organic Farming Matter?
Organic agriculture is more than just avoiding synthetic pesticides and fertilizers. The Food and Agriculture Organization (FAO) describes it as a way of farming that focuses on soil health, biodiversity, and ecological balance.
For families, choosing organic produce can reduce exposure to pesticide residues. Still, the bigger win comes from eating a wide variety of fresh fruits and vegetables, whether organic or conventionally grown. The FAO also notes that organic systems rely on crop rotation and natural pest management, and they can support dietary diversity and healthier eating habits.

How Does Organic Farming Help the Soil?
Everything on those market tables starts in the ground. Organic farmers use compost, crop residues, and cover crops to preserve soil organic matter. That matters because organic matter strengthens soil structure, water retention, nutrient cycling, and it helps soil resist erosion.
Healthy soil leads to healthy crops and stronger farms. It also helps ensure food can be grown for future generations. Instead of relying only on synthetic products, organic farming works to keep soil fertile and full of life.
How Can You Support Local Farmers?
Every purchase at the market supports Filipino organic farmers, producers, and their families. Buying local organic goods gives small producers wider access to buyers and strengthens an increasingly sustainable food system. It also gives kids a chance to meet the people who grow what lands on the dinner table.
The OA Tiangge is open until Nov. 12 at the DA Central Office Main Lobby from 8 am to 5 pm. As the tagline says: “Organikong Pagkain, sa Pamilya ay Ihain!”
