Fertilization with Buffer Tank in Cocopeat and Hydroponic Systems: Professional Guide
The biggest challenge faced by producers engaged in cocopeat and hydroponic cultivation is the precise management of the nutrient solution. Sudden EC and pH fluctuations in traditional fertilizer injection systems can lead to damages worth thousands of liras. But what if fertilizers were mixed and optimized in a controlled environment before being delivered to the main line? This is exactly what buffer tank technology does.
In this guide, you will learn how the buffer tank system works in professional cocopeat and hydroponic production, why it is necessary, and how the Esular Smart Agro MEGA solution provides a yield increase.
Cocopeat and Hydroponics: Environments with Zero Error Tolerance
Unlike soil-based agriculture, cocopeat and hydroponic systems do not have buffering capacity. This situation makes nutrient management extremely critical.
Soil vs. Cocopeat: Critical Differences
Cultivation in Soil: Soil has the ability to hold nutrients within itself and absorb sudden changes. Even if the pH varies between 5.5-7.5, plants can adapt to this situation. Even changes of ±0.5 mS/cm in EC values are buffered by the soil.
Cocopeat and Hydroponic Systems: Although cocopeat, obtained from coconut fibers, has excellent aeration and water retention properties, it has no buffering capacity. Even the smallest changes in the nutrient solution reach the plant roots directly.
| Feature | Soil | Cocopeat/Hydroponic |
|---|---|---|
| Buffering Capacity | High | None ❌ |
| EC Tolerance | ±0.5 mS/cm | ±0.2 mS/cm |
| pH Flexibility | 5.5-7.5 | 5.5-6.5 |
| Nutrient Homogeneity | Insignificant | CRITICAL ⚠️ |
| Sudden Change Effect | Slow | SUDDEN and DESTRUCTIVE 🔥 |
Importance of EC and pH Sensitivity
EC (Electrical Conductivity): It is the value showing the total salt concentration in the nutrient solution. In cocopeat cultivation, ideal EC values vary depending on the product but are generally between 1.5-2.5 mS/cm. Research shows that even a sudden EC increase of 0.3 mS/cm can lead to plant stress.
pH Value: Directly affects the availability of nutrients to be taken up by plants. In hydroponic and cocopeat systems, the ideal pH range is 5.8-6.2. When going outside this range, the uptake of iron, phosphorus, and other micro-elements decreases significantly.
Limitations of Traditional Fertilization Systems
As cocopeat and hydroponic cultivation became more widespread, the inadequacies of traditional fertilization systems also began to emerge.
Venturi/Dozatron Type Injectors
Working Principle: Performs mechanical dosing with pressure difference. Does not require electricity and is easy to install.
Basic Problem: No EC/pH control. Fertilizer concentration varies depending on pressure. Homogeneity guarantee cannot be provided.
Suitable Use: Open field agriculture, soil-based production, garden irrigation.
❌ For Cocopeat/Hydroponics: NOT SUITABLE
Standard Injection Systems (EC/pH Controlled)
Working Principle: Fertilizers drawn from different fertilizer tanks with proportional pumps are injected into the main line. EC and pH sensors are available.
Critical Limitation: Measurement is made when fertilizers mix in the main line, but there is no buffering system to prevent sudden changes. Even a small flow change in the system can affect the concentration.
Suitable Use: Medium sensitivity applications, soil-based greenhouse vegetable growing.
⚠️ For Cocopeat/Hydroponics: Usable but NOT OPTIMAL
"But what if fertilizers were mixed in a controlled environment BEFORE being delivered to the main line, and sent to plants AFTER pH/EC was optimized? This is exactly what Buffer Tank technology does..."
Buffer Tank Technology: A Revolutionary Solution
💡 WHAT IS A BUFFER TANK?
"Buffer" means "tampon" in Turkish. A buffer tank is an intermediate storage tank where the fertilizer mixture is prepared, homogenized, and optimized BEFORE being delivered to the main irrigation line. The pH and EC values of the nutrient solution are brought to the ideal level here before being sent to the plants.
Buffer Tank System: Step-by-Step Operation
STEP 1 – Fertilizer Drawing: The programmed recipe comes into play. Fertilizers are drawn from four tanks in specific ratios (e.g., Tank A: 2.5L, Tank B: 1.8L, Tank C: 0.4L, Tank D: 0.3L).
STEP 2 – Transfer to Buffer Tank: Drawn fertilizers and clean water are taken into the 50-200L capacity buffer tank.
STEP 3 – Magnetic Mixing: The magnetic motor runs for 2-5 minutes to create a 100% homogeneous mixture. Even micro-elements are distributed evenly.
STEP 4 – Measurement and Optimization: EC and pH sensors inside the buffer tank perform continuous measurements. Target values:
- Target EC: 2.0 mS/cm → Current: 2.15 mS/cm → System performs automatic dilution ✅
- Target pH: 6.0 → Current: 6.4 → Acid dosing is performed ✅
STEP 5 – Controlled Output: READY and OPTIMIZED nutrient solution exits from the buffer tank. Balanced feeding is provided to plants, the risk of sudden shock is ZERO.

💡 WHY MEGA?
The key to success in cocopeat and hydroponic systems is a homogeneous and stable nutrient solution. Venturi systems (Mini/Maxi) operate with pressure difference and do not allow precise control. The buffer tank technology in MEGA ensures that fertilizers are brought to optimum values before being delivered to the main line. 100% homogeneous distribution is achieved with magnetic mixing. This is vital in cocopeat and hydroponics.
