Water-Fertilizer Integrated Machine – Working Principle & Practical Application

 Core Driver of Smart Agriculture: NiuBoL Water-Fertilizer Integrated Machine – Working Principle & Practical Application

Definition and Core Value of Water-Fertilizer Integration Technology 

Amid global water scarcity and rising food safety demands, traditional “flood irrigation + heavy fertilization” is no longer sustainable. Water-fertilizer integration is recognized worldwide as a revolutionary innovation that saves resources and protects the environment. 

 Definition: Precise, Synchronous Delivery of Water and Nutrients 

Water-fertilizer integration dissolves fully soluble fertilizers in irrigation water and delivers the nutrient solution evenly and accurately to the crop root zone through pressurized systems (drip, micro-sprinkler, etc.). Its core objective is to supply water and nutrients quantitatively, on schedule, and in exact proportions according to crop demand throughout the growth cycle, dramatically improving resource use efficiency.

 Revolutionary Benefits of NiuBoL Intelligent Water-Fertilizer Machine

- Up to 60% water savings  

- Up to 50% fertilizer savings  

- Approximately 30% yield increase  

- Reduced fertilizer runoff and volatilization → lower environmental pollution  

- Automated & remote operation → dramatically reduced labor costs 

 Technical Core: Working Principle of the NiuBoL Water-Fertilizer Integrated Machine 

Intelligent operation results from the synergy of physics, electrochemistry, and automation. 

 Fertilization Principles: Venturi Effect + Booster Pump Injection 

The machine is installed in parallel with the main irrigation pipeline. NiuBoL primarily uses booster pump injection + Venturi for maximum reliability. 

1. Venturi Principle  

   - Water accelerates through a constricted section → pressure drops (Bernoulli’s principle)  

   - The resulting vacuum sucks liquid fertilizer from tanks through dedicated channels into the main flow for uniform mixing. 

2. Booster Pump Injection (Primary method in NiuBoL)  

   - Industrial-grade stainless steel fertilizer pump (rated 4 m³/h, 72 m head)  

   - Actively injects fertilizer into the main line  

   - Key requirement: Pump head > main pipeline pressure at injection point 

 Precision Proportional Control

- Multi-channel fertilization: Standard 3 channels (expandable), simultaneous injection of N, P, K, micronutrients, etc.  

- Flow control: Float or Hall-effect flow meters on each channel for real-time monitoring and manual/automated proportion adjustment  

- Safety components per channel: Solenoid valve (timing), check valve (prevents backflow), filter (prevents clogging)  

- EC/pH real-time monitoring: Static and dynamic sensors ensure the mixed solution stays within optimal nutrient and pH ranges 

 Cloud-Edge-Terminal IoT Architecture

- Cloud: Agricultural IoT APP & platform – remote monitoring, data storage, analytics  

- Terminal: Industrial host with 10-inch touchscreen – data acquisition, storage, control, HMI  

- Edge: Wireless modules, soil moisture, weather, illumination sensors, wired/wireless valve controllers

 Structural Components & Head-Hub Functions 

The NiuBoL machine serves as the “head hub” of the entire smart irrigation system. 

 Installation Specifications, Application Scenarios & Model Selection Guide 

 Installation Requirements

1. Parallel connection with main irrigation line  

2. Filtration mandatory upstream (centrifugal + sand + disc filters) to protect drippers  

3. Power supply: Three-phase four-wire 380 V (stable supply required)  

4. Shelter recommended (pump house) despite corrosion-resistant cabinet 

 Typical Applications

- High-value crops: Greenhouse vegetables, strawberries, grapes, tomatoes  

- Field crops: Corn, wheat, cotton on large-scale farms  

- Protected horticulture: Smart greenhouses, flower nurseries, soilless systems  

- All pressurized irrigation types: drip, micro-spray, subsurface drip 

 Selection Recommendations

1. Number of fertilizer channels (standard 3 for N-P-K + micros)  

2. Required injection rate (standard max 600 L/h per channel)  

3. Pump head must exceed maximum pipeline pressure  

4. Prioritize models with real-time EC/pH control, pressure alarm, and full IoT remote capability for true unattended operation

 FAQ 

Q1: What is the operating voltage?  

A1: Industrial fertilizer pump: 380 V three-phase or 220 V two-phase; overall system usually 380 V three-phase four-wire. 

Q2: How does it achieve ~50% fertilizer savings?  

A2: Traditional methods lose 60–70% of nutrients to leaching/volatilization. Water-fertilizer integration delivers nutrients directly to the root zone, raising utilization from 30–40% to 70–80+%. 

Q3: Why monitor EC and pH?  

A3: EC reflects total ion (nutrient) concentration; pH affects nutrient availability. Real-time control prevents deficiencies, toxicities, and antagonisms. 

Q4: Fertilizer requirements?  

A4: Only 100% water-soluble solid or liquid fertilizers. Insoluble types will clog pipes and emitters. 

Q5: Purpose of filters on suction channels?  

A5: Remove particles and residues from fertilizer tanks to protect pump and main line. 

Q6: Venturi vs booster pump injection?  

A6: Venturi is passive (relies on main flow pressure drop); booster pump is active, more stable, and overcomes high pipeline pressure. NiuBoL uses booster pump for superior reliability. 

Q7: Will the system stop if pressure is too high?  

A7: Yes – pressure sensors trigger automatic shutdown when limits are exceeded, protecting equipment. 

Q8: How do one-touch irrigation/fertilization modes work?  

A8: Pre-program zones, duration, volume, and ratios on touchscreen or APP; one tap executes the full automated sequence. 

Q9: How is zone irrigation achieved?  

A9: Standard 3 external solenoids + expandable wireless/decoder controllers (up to 254 zones) enable timed, sequential, crop-specific irrigation. 

Q10: Can it integrate with weather stations and soil moisture sensors?  

A10: Yes – reserved interfaces accept meteorological and soil sensors for dynamic, data-driven irrigation and fertilization decisions.

 Conclusion: Stepping into a New Era of Precision Water-Fertilizer Management
