Agriculture consumes 70% of the world’s freshwater while facing increasingly frequent droughts. Our research in agricultural IoT, which has evolved into AgriTech IoT, studies how smart sensors and predictive models could reduce water consumption by up to 40% while maintaining yields. This is a theoretical analysis based on simulations and small controlled experiments.
The Problem: Blind Agriculture vs. Smart Agriculture
Farmers make critical decisions with limited information: When to irrigate? How much to fertilize? Which pests are attacking? 60% irrigate «by calendar» or «by experience,» ignoring the actual needs of the crop. This research explores whether a network of IoT sensors could change that reality.
We identified three fundamental challenges in traditional agriculture:
- Delayed information: Problems are detected when it’s already too late to act
- Uniform decisions: The entire plot is treated equally, ignoring microclimates
- Resource waste: Excess water, fertilizers, and pesticides for prevention
Methodology: Research in Pilot Plots
Our research combines small-scale controlled experiments with advanced predictive models:
Phase 1: Experimental Sensor Network
We installed 24 sensors in 3 plots of 500m² each (tomato, lettuce, corn) for 8 months. We monitored: soil moisture, ambient temperature, pH, electrical conductivity, solar radiation, and wind speed. Scale: experimental, not commercial.
Phase 2: Predictive Models with AI
With 2.3 million collected data points, we trained machine learning models to predict: water needs 48h in advance, pest risk, optimal harvest time. Average accuracy in simulations: 73-89%.
Phase 3: Validation and Projections
We compared «smart» vs «traditional» plots in our controlled experiment. The results feed projections for AgriTech IoT, currently in development.
Preliminary Experimental Results
Note: The following data comes from our small-scale experiments. These are not results from commercial implementations.
Efficiency by Crop (500m² Plots):

Experimental average: -34% water, +13% yield • In 1,500m² plots over 8 months
Technical Challenges Encountered
Rural connectivity: 67% of agricultural areas lack stable 4G coverage. We developed LoRaWAN protocols that work up to 15km without repeaters, but with data limitations.
Environmental durability: Sensors exposed to UV, extreme humidity, and temperatures from -5°C to 45°C. Failure rate: 23% annually. We need better encapsulation.
Farmer adoption: Technology intimidates. We designed ultra-simple interfaces: color traffic lights (green = don’t irrigate, red = irrigate urgently). Still, 40% prefer their traditional method.
The AgriTech IoT Project: Current Status
AgriTech IoT was born from this research. Currently in development phase, we’re working on:
- Second-generation sensors: More resistant, 50% cheaper
- Adaptive algorithms: That learn from each specific plot
- Tests with 8 farmers: On 1-3 hectare plots
- Business model: Monthly subscription vs hardware sale
Current reality: It’s promising but complex. Farmers want immediate results; the technology needs time to «learn» each plot.
Social Impact: Beyond Efficiency
In our experiments, participating farmers reported 60% reduction in time dedicated to manual irrigation. They free up time for other activities or additional crops. One commented: «For the first time I sleep peacefully knowing my plants are fine».
But we also discovered resistance: fear of technological dependency, concern about hidden costs, skepticism about efficiency promises. These are real challenges we must address.
Research Expansion
Preliminary results opened new research lines:
- Smart greenhouses: Automated climate control
- Precision livestock: Sensors for animal welfare
- Digital viticulture: Vineyard-specific optimization
- Vertical farming: IoT for urban crops
- Agricultural blockchain: Traceability from seed to consumer
Limitations and Next Steps
Current limitations: Small experiments (1,500m²), a single crop cycle, controlled conditions. For commercial validation, we need tests on 100+ hectares for at least 3 years.
Next 18 months: Validation with real farmers, sensor improvement, mobile app development, profitability analysis. No exaggerated promises, just constant work.
Conclusion: Smart Agriculture, Step by Step
Our research demonstrates that agricultural IoT has real potential, but it’s not a magic solution. It requires investment, patience, and close collaboration with farmers. Preliminary results are promising: less water, higher yields, better quality of life.
With AgriTech IoT we don’t seek to replace the farmer’s experience, but to amplify it. Technology informs, the farmer decides. In that symbiosis between tradition and innovation lies the future of more sustainable and efficient agriculture.
