Smart Farming at Stone Hill: How Water Management Drives Sustainability

Water: The Lifeblood of Sustainable Farming

Continuing the story of Stone Hill’s revival under Teacher Phước, today we explore how water management played a critical role in transforming a barren hill into a thriving farm and forest.

Previously, I discussed how soil enrichment prepared the land for cultivation. Now, let's focus on how water solutions made sustainable farming possible.

Stone Hill’s Approach to Sustainability

While organic methods are prioritized, Stone Hill’s model is not entirely organic—some dissolved chemical fertilizers are integrated into drip irrigation for cacao and other crops.

At first, I questioned this approach. But over time, I understood its logic:

✅ Plants need essential nutrients, and they must be supplied efficiently.
✅ Balanced fertilization, when done scientifically, boosts productivity better than relying solely on compost.

Though I also trained in natural pest control for cacao farming, I won’t cover that here—today’s focus is solely on water management strategies.

Water Sources & Storage Solutions

Water always comes before fertilizer—a principle every farmer understands. At Stone Hill, two main solutions were implemented:

1️⃣ Locating underground water on the hill and redirecting it into reservoirs.
2️⃣ Drilling wells for daily use and storing water for the dry season.

At first, the water supply seemed sufficient, but after years of observation, mountain springs began drying up. To solve this:

• Eight separate drilling attempts were made, facing financial challenges.
• Eventually, a stable water source was secured.
• The next step: building reservoirs for long-term storage.

This process was not easy, but it laid the foundation for sustainable resource management at Stone Hill.

Water Allocation & Integrated Fertilization

Since water is limited, drip irrigation was chosen for maximum efficiency. This system offers several advantages:

✅ Precise nutrient distribution – Fertilizers are delivered directly to the roots.
✅ Reduced pests & diseases – Water doesn’t settle on leaves, preventing rot.
✅ Labor & cost savings – A key long-term investment in farm productivity.

Though the concept sounds simple, its practical implementation can be complex. The irrigation system at Stone Hill consists of three key components:

1️⃣ Pumping, filtration & Venturi system – Manages water intake & fertilizer mixing.
2️⃣ Pipeline design – Ensures balanced flow rate, matching pump capacity.
3️⃣ Remote control automation – Allows farmers to irrigate crops from anywhere.

This approach significantly boosts efficiency while conserving water—a method that sets Stone Hill apart in Vietnam’s evolving agricultural landscape.

Reflections on Sustainable Farming

Stone Hill’s water strategy represents a scientific, structured approach to modern agriculture. Everything is digitalized, driven by plant-specific data to ensure precision & efficiency.

For farms that aren’t fully organic, integrating fertilizers into drip irrigation proves:
✅ Effective
✅ Convenient
✅ Cost-saving

However, at HuyEco Coffee Farm, we’re still rebuilding, and I remain committed to 100% organic fertilizers. That said:

• Automated irrigation is an excellent solution for labor reduction.
• It allows farmers to focus on harvesting, processing & sales, rather than manual watering.

For large-scale farms, mechanization & technology are inevitable. I firmly believe that Vietnam’s agricultural future will embrace automation, making farming smarter, more efficient & sustainable.
