I. Executive Summary
This report provides a strategic analysis of the three core pillars of artificial intelligence in modern agriculture: in-field diagnostics, satellite-based monitoring, and predictive yield modeling. It finds that while these pillars are often developed as siloed “point solutions,” their exponential value and competitive defensibility are only unlocked through their systematic integration.
The analysis of Pillar 1 (In-Field Diagnostics), benchmarked by the PlantVillage dataset, confirms that while lab-based models achieve near-perfect accuracy, a significant “lab-to-field performance gap” renders them ineffective in real-world conditions. The prevailing strategic response is not a new model architecture, but a new deployment model: the cloud-hybrid, on-device application. This model solves the critical “last-mile” problem of offline access while simultaneously creating a data-acquisition flywheel, turning the farmer into a data-collection agent to systematically solve the performance gap.
For Pillar 2 (Satellite Monitoring), this report concludes that semantic segmentation is the foundational data-processing layer, not the end-product. Its primary function is to provide high-purity, time-series data—such as the Normalized Difference Vegetation Index (NDVI)—by isolating crop pixels from background noise. The strategic choice between free (Sentinel-2) and paid (Planet) data is a trade-off between baseline monitoring and the high-margin, “in-season tactical” products enabled by high-cadence daily monitoring.
In Pillar 3 (Yield Prediction), the dominance of Random Forest (RF) and XGBoost is confirmed. However, the core finding is that model performance is overwhelmingly a function of feature engineering, not model architecture. The most significant strategic distinction is between “pre-season” (strategic) forecasting and “in-season” (tactical) forecasting, with the latter being entirely dependent on the high-cadence data stream from Pillar 2.
The report’s central thesis is that the future of agricultural AI lies in the integration of these three pillars into a “Digital Twin” of the farm. In this integrated stack, in-field diagnostics (Pillar 1) provide the “ground-truth” to explain anomalies detected by satellite monitoring (Pillar 2). Both data streams then serve as proprietary, high-value features that are the missing link to unlocking new levels of accuracy in yield prediction (Pillar 3). This “sense-predict-act” system is the prerequisite for enabling prescriptive decision support and, ultimately, autonomous farm operations.
Key strategic recommendations derived from this analysis are to:
- Prioritize the Data Integration Pipeline: Focus investment on data engineering, interoperability, and MLOps to fuse the three pillars, as this is the primary bottleneck, not model architecture.
- Invest in Ground-Truth Acquisition: Fund or acquire a Pillar 1-style mobile application. This is the most cost-effective method to acquire the “messy” field data needed to solve the “lab-to-field” gap and create proprietary predictive features.
- Build for Interpretability (XAI): Mandate the use of SHAP or similar XAI techniques to build farmer trust, which is a critical barrier to adoption.
II. The New Digital Agronomy: A Three-Pillar Framework
The Scale of the Challenge
The application of advanced artificial intelligence in agriculture is not an academic exercise; it is a direct response to critical, compounding global challenges. The economic stakes are staggering, with the annual global economic loss from plant diseases alone estimated at $220 billion. This financial burden is inextricably linked to the existential pressure of global food security, a domain where AI is now uniquely positioned to provide scalable, transformative solutions.
The Problem’s Concentration
While the scale of the problem is immense, its causal structure is highly concentrated. An estimated 90% of global crop losses are attributed to just eight disease pathogens. The combination of this immense economic damage with the high concentration of its cause creates a unique strategic opportunity. It implies that a highly targeted technological intervention can have an asymmetric, outsized impact. The entire report, therefore, analyzes the specific technological stack designed to execute this targeted intervention. This strategic context validates the focus on crop disease detection, high-resolution monitoring, and predictive yield modeling as the highest-impact levers for change.
Establishing the Three-Pillar Framework
This report is structured around a three-pillar framework that represents a multi-scale “sense-and-respond” system for modern agronomy. These pillars, often treated as separate markets, are analyzed here as essential, interconnected components of a single stack:
- Pillar 1 (In-Field): The “micro-scale” view. This concerns high-fidelity, ground-truth data collection at the individual plant level, primarily using computer vision for disease and pest diagnostics.
- Pillar 2 (Remote): The “macro-scale” view. This provides scalable, wide-area monitoring at the field and regional level, primarily using satellite imagery and segmentation models.
- Pillar 3 (Predictive): The “temporal” view. This is the forecasting engine that fuses data from the micro and macro pillars to predict future outcomes (e.g., yield) and prescribe optimal actions.
The Central Thesis: From Point Solutions to an Integrated Stack
The central argument of this report is that while the market currently sells these pillars as separate products—a “disease app,” a “satellite map,” a “yield forecast”—their true, defensible value is unlocked only when they are integrated. The fusion of these data streams into a single, cohesive data pipeline creates a system that is far more valuable than the sum of its parts. This integrated stack is the foundation for creating a true “Digital Twin” of the farm, enabling a shift from reactive decision-making to predictive and prescriptive autonomous operations.
III. Pillar 1: In-Field Diagnostics — The PlantVillage Precedent
A. Analysis of PlantVillage-Type CV Models
The field of smartphone-based crop disease diagnostics was catalyzed by the creation of the PlantVillage dataset. This public benchmark, containing 54,306 images of both healthy and diseased plant leaves, covers 14 different crops and 38 distinct disease classes.
The initial, and most widely cited, result from this dataset was a 99.35% accuracy in classifying crop diseases. This remarkable “lab” benchmark was achieved using Deep Convolutional Neural Networks (CNNs). The models trained and benchmarked on this dataset represent a “who’s who” of state-of-the-art architectures, including high-performance models like VGG16, InceptionV3, and ResNet, as well as foundational models like AlexNet and GoogleNet. These results established that, under controlled conditions, CNNs could perform diagnostic tasks with superhuman accuracy.
B. From Lab to Field: Bridging the “Performance Gap”
The most critical challenge in this pillar is the “performance gap” between the lab and the field. The 99.35% accuracy achieved on the sanitized PlantVillage dataset is misleading. Multiple studies testing these same models in real-world field conditions found that they “significantly underperformed”.
A causal analysis of this gap reveals that the models, trained on clean images with simple backgrounds, fail when confronted with real-world visual complexity. These failure modes include:
- Complex backgrounds (soil, weeds, or other plant matter).
- Variable and uncontrolled lighting conditions and shadows.
- Different stages of disease presentation (e.g., early vs. late blight).
- Co-infections, where multiple diseases are present on a single leaf.
- Phenotypical variations in different plant genetics.
This conflict between lab perfection and field failure is not a model failure; the architectures themselves are demonstrably powerful. It is a data strategy failure. The models were trained on a biased, “clean” dataset. The strategic priority for any organization seeking to deploy Pillar 1 technology is therefore not to invent a new, more complex CNN architecture. The priority is to invest in a data acquisition pipeline that captures large volumes of messy, geotagged, real-world images from the field. This new dataset is then used to retrain and fine-tune existing, proven architectures, closing the performance gap by making the training data representative of the deployment environment.
C. Deployment Architectures: On-Device vs. Cloud-Hybrid Models
The target end-user—a farmer or agronomist—is often operating in “remote areas without internet connectivity”. This constraint makes cloud-only models non-viable and creates a non-negotiable requirement for “real-time diagnosis on edge devices“, such as a standard smartphone.
This has driven a necessary shift away from heavy, compute-intensive models (e.g., VGG16) toward lightweight, efficient architectures optimized for mobile CPUs and GPUs. Key models in this category include MobileNetV2 and DarkNet19. The standard deployment stack for these models is TensorFlow Lite, which allows for efficient on-device inference.
The most commercially successful and strategically sound deployment is the cloud-hybrid model, exemplified by applications like Plantix. This model operates in a three-step flow:
- Step 1 (Edge): A lightweight on-device model (e.g., MobileNetV2) performs initial inference, providing immediate, offline diagnostic value to the user.
- Step 2 (Cloud): When connectivity is available, the captured image (along with its geotag and user label) is uploaded to a much larger, more powerful cloud-based model for confirmation and aggregation.
- Step 3 (Network): The aggregated data is fed into a “community network,” allowing for real-time monitoring of disease spread—a crucial link to Pillar 3.
This hybrid model is not merely a technical compromise; it is a sophisticated data acquisition strategy. The “problem” of offline access is solved by the edge model. This edge model provides the user value (instant diagnosis) required to incentivize the user to capture and later upload the image. This creates a virtuous cycle: the edge model provides value, which drives data collection. This new, “messy” field data is used to retrain the central cloud model, which is then re-compiled into a better edge model. This system turns the product itself into the data collection engine, systemically solving the “lab-to-field” gap.
D. Limitations and Emerging Frontiers
It is critical to understand the current limitations of these models. They notoriously struggle to differentiate between diseases that present with similar visual symptoms. Their most significant failure, however, is the inability to reliably distinguish nutrient deficiencies (e.g., nitrogen chlorosis, which causes yellowing) from diseases (e.g., fungal yellowing). This ambiguity is a major barrier to providing automated, trustworthy treatment recommendations.
The clear next frontier for this technology is expanding its scope beyond disease. Pest detection is the logical next step, using similar computer vision techniques to identify and count harmful insects.

| Model Architecture | “Lab” Accuracy (PlantVillage) | “Field” Performance | Model Size (MB) | Inference Speed | Primary Deployment | Key Limitation |
| VGG16 | $\gt 99\%$ | Poor | $\sim 530$ MB | Slow | Cloud-Only | High compute; poor generalization |
| ResNet-50 | $\gt 99\%$ | Poor-to-Fair | $\sim 98$ MB | Moderate | Cloud-Only | Sensitive to complex backgrounds |
| MobileNetV2 | $\sim 98.5\%$ | Good (when retrained) | $\sim 14$ MB | Very Fast | Edge-Capable (TFLite) | Lower accuracy; needs field data |
| DarkNet19 | $\sim 98\%$ | Good (when retrained) | $\sim 80$ MB | Fast | Edge-Capable | Less common; needs field data |
IV. Pillar 2: Satellite-Based Monitoring — Segmentation as a Foundational Layer
A. The State of the Art in Agricultural Semantic Segmentation
Moving from the “plant” scale to the “field” scale, Pillar 2 leverages remote sensing data, primarily from satellites. The foundational AI task in this pillar is “segmentation”—the pixel-level classification of an image. In agriculture, this is not a single task but several distinct objectives:
- Crop Type Classification: Delineating all “corn” pixels from “soy” pixels within a region.
- Field Boundary Delineation: Drawing a precise, vector-based polygon around a specific field.
- Health/Stress Segmentation: Identifying and mapping in-field zones of “water stress,” “disease,” or “nutrient deficiency”.
The architectures used are specialized for these tasks. For pixel-level classification (crop type, stress mapping), Semantic Segmentation models are the workhorses. Architectures like U-Net and DeepLabv3+ are highly effective. The U-Net architecture, in particular, is repeatedly cited as a high-performing and efficient model for this purpose.
For field boundary delineation, Instance Segmentation models like Mask R-CNN are superior. A semantic model (U-Net) can only identify a pixel as “field,” whereas an instance model (Mask R-CNN) can identify it as belonging to “Field 1,” distinct from “Field 2”.
This distinction in architectures is not merely technical; it serves different business goals. A U-Net model mapping in-field zones is the priority for products enabling precision application (e.g., Variable Rate irrigation). Conversely, a Mask R-CNN model providing a perfect, clean field boundary is the critical first step for Pillar 3 yield forecasting, as it defines the “unit of analysis” for the yield model.
B. Data Sources and Model Efficacy: The Cost vs. Cadence Trade-off
The efficacy of these segmentation models is entirely dependent on the underlying satellite data, which involves a strategic trade-off between resolution, cadence, and cost.
- Public (Free) Data:
- Sentinel-2 (EU): The gold standard for free, public data. It offers a high spatial resolution (10m) and a high temporal resolution (5-day revisit).
- Landsat (USGS): Provides a much longer historical archive but has a lower resolution (30m spatial, 16-day temporal).
- MODIS: Offers high-cadence (daily) data but at a very low resolution (250m+), making it suitable for regional analysis but not field-level work.
- Commercial (Paid) Data:
- Planet (formerly Planet Labs): The market leader, operating the largest constellation. It provides an unprecedented combination of high spatial resolution ($\sim 3\text{m}$) and daily temporal cadence.
- DigitalGlobe (Maxar): Offers “very high” sub-meter resolution but at a lower temporal cadence.
The choice between free (Sentinel-2) and paid (Planet) data is a strategic one. The business case for paid data is its temporal cadence. High-resolution temporal data is critical for accurately monitoring “critical growth stages” (phenotyping). A 5-day revisit cycle from Sentinel-2 can miss a critical, short-duration event like a fungal bloom or a brief period of water stress. The daily cadence from Planet enables a new class of high-margin, “in-season tactical” products (e.g., daily irrigation advice, immediate pest alerts) that free data simply cannot support.
C. Beyond Delineation: Using Segmentation for Temporal Health Monitoring
It is essential to understand that segmentation is the prerequisite, not the final product. Its function is to clean the data by isolating the relevant field pixels from non-crop pixels (roads, shadows, buildings).
Once these crop-only pixels are segmented, they are aggregated to calculate time-series Vegetation Indices. This is the core “monitoring” task. Key indices include:
- NDVI (Normalized Difference Vegetation Index): The most common index, measuring biomass and general vigor.
- EVI (Enhanced Vegetation Index): Similar to NDVI but corrects for atmospheric noise and soil background effects, making it more reliable.
- SAVI (Soil-Adjusted Vegetation Index): Particularly useful in early growth stages when soil is visible between plants.
The real value of Pillar 2 is unlocked by plotting these indices over time. This “growth curve,” or phenological profile, is the primary data product. It allows for monitoring crop health in near-real-time and identifying deviations from the norm. These deviations are powerful indicators of in-field problems, including “water stress, nitrogen deficiency, and disease outbreaks”. This time-series data stream is the single most important in-season input for the Pillar 3 prediction models.

| Data Source | Spatial Res. | Temporal Res. | Cost | Primary Use Case | Optimal Segmentation Model |
| Sentinel-2 | 10m | 5 days | Free | Field-level health monitoring, Boundary Delineation | U-Net, Mask R-CNN |
| Landsat 8/9 | 30m | 16 days | Free | Historical analysis, Regional crop-type classification | U-Net, DeepLabv3+ |
| Planet | $\sim 3\text{m}$ | Daily | $$$$ | In-season tactical monitoring, Phenotyping | U-Net (for stress), Mask R-CNN |
| MODIS | 250m+ | Daily | Free | Regional drought/yield models (not field-level) | N/A (pixel-based) |
V. Pillar 3: Yield Prediction — The Dominance of Ensemble Methods
A. Deconstruction of Random Forest and XGBoost Implementations
This pillar moves from “sensing” to “forecasting.” The analysis confirms the premise that Random Forest (RF) and XGBoost are “widely adopted” for crop yield prediction.
Their dominance over other models (like Support Vector Regression or traditional Artificial Neural Networks) is due to their exceptional ability to handle the specific data types in agriculture. They “excel at handling complex, non-linear relationships“, which define biological systems. Most importantly, they are highly “robust to outliers and missing data”—a non-negotiable requirement for agricultural data, which is notoriously messy, incomplete, and noisy.
A strategic trade-off exists between the two:
- Random Forest (RF): Generally “more robust and less prone to overfitting,” and is “easier to implement”.
- XGBoost: “Often provides higher accuracy” but is “more sensitive to hyperparameter tuning”.
This choice is not just technical; it is a signal of organizational maturity. RF’s robustness makes it the ideal choice for prototyping and establishing a reliable baseline. The superior accuracy of XGBoost can only be realized and maintained with a mature MLOps pipeline and a very clean, stable feature set. Pursuing XGBoost’s marginal accuracy boost is an inefficient use of resources if the data pipelines from Pillars 1 and 2 are not yet mature.
B. The Critical Role of Feature Engineering
The single most important finding in this pillar is that the choice of model is secondary to the quality and diversity of the features. “The integration of multi-source data is the key determinant of model performance”. Model performance is a function of feature engineering.
Baseline models are built using standard, historical data:
- Weather: Temperature, precipitation, growing degree days (GDD).
- Soil: Soil type, organic matter content, pH, water holding capacity.
- Management: Planting density, fertilizer rates (N, P, K), seed variety, and planting date.
The “alpha,” or predictive edge, comes from advanced, real-time features. This is where the pillars connect. Integrating time-series NDVI, EVI and other vegetation indices from Pillar 2 is the most powerful in-season feature set.
Given the high dimensionality of these combined datasets, feature selection techniques (e.g., Recursive Feature Elimination, VIF analysis) are critical. Furthermore, because these ensemble models are “black boxes,” they face a significant adoption barrier: farmer trust. To overcome this, Explainable AI (XAI) techniques, particularly SHAP analysis, are essential. SHAP values can explain why a forecast was made (e.g., “Yield forecast reduced by 5% due to a 10-day NDVI decline in zone 3”), which is critical for model validation and user trust.
C. Performance Benchmarks and the Strategic Divide
When well-tuned and fed a rich, multi-source feature set (including Pillar 2 data), these models can achieve high predictive power, with R-squared values typically falling between 0.75 and 0.90.
A critical, market-defining distinction exists in when the forecast is made:
- Pre-Season Estimation: Forecasts made before planting. These models rely heavily on static, historical data: soil type, historical weather averages, and long-range climate forecasts.
- In-Season Forecasting: Forecasts that are updated during the growing season. These models rely heavily on real-time data—specifically, the remote sensing (NDVI/EVI) features from Pillar 2.
This is not a minor technical detail; it describes two completely different business products serving two different markets. A “pre-season” model is a strategic tool for commodity traders, insurance companies, and input suppliers (e.g., “How much nitrogen fertilizer will be needed in the corn belt?”). An “in-season” model is a tactical tool for farmers and agronomists (e.g., “Based on current conditions, should I apply a costly fungicide to this field next week?”). The technical architecture required for the in-season product—namely, the high-cadence Pillar 2 data pipeline—is far more complex and costly, but it supports higher-margin, decision-based products.

Part A: Model Comparison
| Model | Typical R-squared | Robustness to Missing Data | Sensitivity to Tuning | Interpretability (with SHAP) |
| Random Forest | 0.75 – 0.85 | High | Low | Medium-High |
| XGBoost | 0.80 – 0.90 | Medium | High | Medium-High |
| SVR | 0.60 – 0.75 | Low | Medium | Low |

VI. Strategic Analysis: The Integrated Agri-Modeling Stack
A. Data-as-a-Feature: The Data Fusion Pipeline
The true value of this three-pillar system is realized in the data fusion pipeline, where the outputs of one pillar become proprietary features for another.
- Pillar 2 -> Pillar 3 (The Established Link): This is the most obvious and established integration. The output of Pillar 2—a time-series of vegetation indices (NDVI/EVI) for a precisely segmented field—is the highest-value in-season feature for the Pillar 3 yield model.
- Pillar 1 -> Pillar 3 (The Novel Link): This connection represents a key strategic opportunity. Pillar 2’s NDVI is excellent at detecting “stress” but often cannot identify the cause. Is the low-NDVI zone due to water stress, nitrogen deficiency, or a fungal blight? Pillar 1, the diagnostic app, can identify the specific cause. An organization that aggregates anonymized, geotagged disease diagnoses from a Pillar 1 app can create a powerful, proprietary feature for its Pillar 3 yield model—a “Disease Pressure Score” for a given county or region. This feature explains yield variance that satellites cannot see, giving the model a significant competitive edge.
- Pillar 1 <-> Pillar 2 (The Feedback Loop): This is the most advanced integration, creating a “ground-truthing” system.
- Step 1: The Pillar 2 satellite model (e.g., U-Net) detects an anomaly (a low-NDVI zone).
- Step 2: This automatically triggers a “scouting task” in the Pillar 1 mobile app, directing the farmer to the exact GPS coordinates of the anomaly.
- Step 3: The farmer uses the app to take a photo, “ground-truthing” the anomaly as, for example, “Northern Corn Leaf Blight.”
- Result: This new, human-verified data point is used to retrain and improve the Pillar 2 stress model (teaching it what blight looks like from space) and provides a confirmed, high-impact input for the Pillar 3 yield model.
B. Creating a “Digital Twin” of the Farm
This integrated stack is the foundation of a “Digital Twin”—a living, dynamic model of the farm. The pillars map to the twin’s layers:
- Static Layer: Soil type, genetics, and field boundaries (from Pillar 2).
- Dynamic Layer: Real-time NDVI/EVI (from Pillar 2), real-time weather, and confirmed disease/pest reports (from Pillar 1).
- Predictive Layer: The RF/XGBoost models (Pillar 3) that forecast the future state of the twin.
The output of this digital twin is not just a passive forecast, but active, prescriptive decision support, such as “Nitrogen deficiency detected in Zone 3; prescription is 25 lbs/acre.”
C. Gaps, Bottlenecks, and Data Silos
Significant barriers to this integration remain.
- Technical Gaps: The “lab-to-field” gap in Pillar 1 and the persistent misidentification of nutrient deficiencies vs. disease are unsolved.
- Data Bottlenecks: The cost of and access to high-cadence satellite data is a major hurdle. More importantly, there is a systemic scarcity of the “ground-truth” data needed to train all three pillars.
- The Silo Problem: The primary organizational barrier is that data is locked in proprietary systems: farm equipment data (e.g., John Deere, CNH), agronomy/input data (e.g., Bayer, Syngenta), and imagery data (e.g., Planet, Climate FieldView). “Data interoperability” is the single greatest non-technical challenge to building this integrated stack.
D. Competitive Landscape and “Buy vs. Build” Analysis
The competitive landscape is defined by companies attempting to own one or more of these pillars (e.g., Plantix in Pillar 1, Planet in Pillar 2, Bayer/Climate Corp. across all three).
A strategic “Buy vs. Build” analysis suggests the following:
- Buy: The raw data. It is rarely economical to build and launch satellites. Buy the imagery from a provider like Planet.
- Partner/Acquire: The in-field diagnostic app. It is difficult to build a user base from scratch. Partner with or acquire a company like Plantix to gain access to the Pillar 1 user base and data stream.
- Build: The proprietary models that sit on top. The defensible intellectual property is in the fusion. Organizations should build their own segmentation models, their unique data fusion pipeline, and their yield prediction models, as this is where competitive advantage is created.
VII. Future Trajectory and Strategic Recommendations
Recommendation 1: Prioritize the Data Integration Pipeline over Model Architecture
The analysis throughout this report consistently demonstrates that the primary performance bottlenecks are related to data, not models. The “lab-to-field” gap, the critical need for “multi-source data” in yield prediction, and the challenge of “ground-truthing” all point to data challenges. The greatest hurdle is interoperability and data fusion.
Action: Invest in data engineering and MLOps to build the robust pipeline that fuses the three pillars. Do not fund a “moonshot” to build a new CNN or ensemble method; fund the pipeline to feed existing, proven architectures with better, more integrated data.
Recommendation 2: Focus Investment on “Ground-Truth” Data Acquisition
The scarcity of labeled, in-field data is the single biggest technical bottleneck. The Pillar 1 / Pillar 2 feedback loop and the commercial success of Plantix demonstrate a clear ROI for “human-in-the-loop” data collection. The hybrid app model provides immediate user value and solves the data scarcity problem by turning farmers into a distributed data collection network.
Action: Fund, acquire, or partner with a “Pillar 1” mobile application. This is the most cost-effective way to acquire the “messy” data needed to solve the “lab-to-field” gap and to create the proprietary “Disease Pressure” features for Pillar 3.
Recommendation 3: Build for Interpretability (XAI) to Drive Adoption
A yield forecast from Pillar 3 that a farmer does not trust is a useless forecast. A “black box” will not be adopted, and its recommendations will not be followed. Trust is a primary barrier.
Trust must be built layer by layer.
- A farmer first trusts what they can see: the Pillar 1 app correctly identifying a disease on a leaf in their hand.
- This builds trust in the Pillar 2 satellite map that correctly flagged that specific spot for scouting.
- This, in turn, builds trust in the Pillar 3 yield forecast that uses those two trusted data points as inputs.
The integration of the stack is therefore not just a technical imperative; it is a trust-building imperative.
Action: Mandate the use of SHAP or similar XAI techniques for all Pillar 3 models. Use the Pillar 1/2 workflow to provide intuitive, qualitative explanations (e.g., “We are lowering your yield forecast because the satellite detected stress in your back 40, which your scout photos confirmed as blight”) alongside the quantitative SHAP charts.
Concluding Analysis: The Path to Autonomous Farm Operations
The long-term vision for this integrated “Digital Twin” is not passive prediction, but active prescription. The final link in the chain is connecting the output of the predictive stack to actuation.
The digital twin’s recommendations (e.g., “Apply 15 lbs/acre N to Zone 3”) can be fed directly, via an API, to smart, variable-rate application (VRA) farm equipment. This equipment—a modern tractor or sprayer—executes the decision precisely. That same equipment then reports back what was applied and where, closing the loop by providing new, verified data to the digital twin. This “sense-predict-act” cycle is the working definition of autonomous farming. The three pillars analyzed in this report are its non-negotiable foundation.
