AI Precision Agriculture System Development

A 1000-hectare field — how to apply fertilizers when the soil is different in every square meter? The traditional approach is uniform application. The result: overfertilization in some areas, underfertilization in others, wasted money. AI solves this task by creating management zones and variable rate application. Our systems already work on fields from 500 to 10,000 hectares in various climatic zones. Instead of treating the entire field the same, we give each section exactly as many resources as it needs. The result: saving up to 25% on nitrogen fertilizers while increasing yields by 10–15% (source: Wikipedia). Our engineers have 12 years of experience in agri-IT, certifications in ML and satellite data processing. We guarantee prediction accuracy and work with fields from 100 hectares. Over 50 successful projects in precision farming, 7 years on the market.

What problems does AI in farming solve?

Field heterogeneity. Soil within a single field can vary in acidity, humus content, and moisture. The traditional approach of uniform fertilizer application leads to over-fertilization in some zones and under-fertilization in others. AI breaks the field into management zones, each receiving its own application rate. Nitrogen fertilizer savings reach 25% with a 10% increase in yield.

Inaccurate yield forecasts. Manual monitoring cannot predict yield a month before harvest. We build models that account for satellite vegetation indices, weather stresses, and soil characteristics. An ensemble of LightGBM, XGBoost, and CatBoost provides predictions with an RMSE of 0.3–0.5 t/ha for wheat. The farmer has time to adjust sales plans and logistics. Average savings from timely contract adjustments reach $15,000 per 500 ha field per season.

Resource overuse. Spraying the entire field with herbicides is expensive and environmentally harmful. Computer vision for agriculture detects weeds and treats only infested areas. Herbicide consumption drops by 60–70%. We use YOLOv8 on drone imagery — weed detection accuracy is 92%. On a 1000 ha field, this saves approximately $30,000 per season on herbicides.

How we build a precision farming system

Data fusion — merging heterogeneous data. All spatial layers are converted to a uniform 10×10 m grid. We use the rasterio library for reprojection. The feature stack includes NDVI, NDRE, elevation, slope, EC, pH, N/P/K. Example code:

import numpy as np
import rasterio
from rasterio.enums import Resampling
from rasterio.warp import reproject, calculate_default_transform

class FieldDataFusion:
    """Combining heterogeneous spatial layers of a field"""

    def __init__(self, target_resolution_m=10):
        self.resolution = target_resolution_m

    def align_to_reference(self, source_path, reference_path, output_path):
        with rasterio.open(reference_path) as ref:
            ref_meta = ref.meta
            ref_transform = ref.transform
            ref_crs = ref.crs

        with rasterio.open(source_path) as src:
            transform, width, height = calculate_default_transform(
                src.crs, ref_crs, src.width, src.height, *src.bounds
            )
            meta = src.meta.copy()
            meta.update({'crs': ref_crs, 'transform': ref_transform,
                        'width': ref_meta['width'], 'height': ref_meta['height']})

            with rasterio.open(output_path, 'w', **meta) as dst:
                reproject(
                    source=rasterio.band(src, 1),
                    destination=rasterio.band(dst, 1),
                    src_transform=src.transform,
                    src_crs=src.crs,
                    dst_transform=ref_transform,
                    dst_crs=ref_crs,
                    resampling=Resampling.bilinear
                )

    def create_feature_stack(self, layer_paths):
        arrays = []
        for path in layer_paths:
            with rasterio.open(path) as src:
                arrays.append(src.read(1))
        return np.stack(arrays, axis=0)

What are management zones and how to create them?

Management zones are field areas with similar agrochemical properties. We create them using clustering: pixels are grouped by long-term NDVI, electrical conductivity, and terrain. We use Fuzzy C-Means — it is 15% more accurate than k-means in overlapping conditions. The optimal number of zones is determined by the elbow method. After clustering, a sieve filter removes small disconnected regions. Typical result: 3–5 zones with different agrochemical properties.

Data pipeline architecture

Sources: Sentinel-2 (NDVI, NDRE), drones (RGB/multispectral), soil sensors (EC, pH), weather stations, combines (yield). All data lands in MinIO (S3-compatible storage). Airflow orchestrates tasks: reprojection, aggregation, feature extraction. Features are stored in PostgreSQL+pgvector for fast similarity search of zones. Models (LightGBM, YOLO) are deployed on Kubernetes using ONNX Runtime for inference.

Computer vision for crops

Monitoring seedlings and weeds from drone imagery. Example seedling counting:

import cv2
import numpy as np
from ultralytics import YOLO

class SeedlingCounter:
    def __init__(self, model_path='seedling_yolov8n.pt'):
        self.model = YOLO(model_path)
        self.calibration = None

    def count_seedlings(self, image_path, gsd_cm=2.0, plot_size_m2=25):
        results = self.model(image_path, conf=0.4, iou=0.3)
        count = len(results[0].boxes)
        density_per_m2 = count / plot_size_m2
        density_per_ha = density_per_m2 * 10000
        target_density = {'wheat': 400, 'corn': 8, 'sunflower': 5}
        crop = 'wheat'
        deviation = (density_per_ha/1000 - target_density[crop]) / target_density[crop]
        return {
            'count': count,
            'density_per_ha': density_per_ha,
            'deviation_pct': deviation * 100,
            'action': 're-sow' if deviation < -0.15 else 'normal'
        }

Our drone agronomy solutions provide high-resolution imagery. Weed identification for spot treatment: drone + YOLO → weed infestation map → prescription map for spot sprayer. Equipment: DJI Agras T40, autonomous spraying by map.

Why does an ensemble of models work better than a single one?

For yield prediction, we use a combination of LightGBM, XGBoost, and CatBoost. Each model has strengths: LightGBM is faster on large data, XGBoost is more robust to outliers, CatBoost handles categorical features without preprocessing. Averaging their predictions reduces error by 10–15% compared to the best single model.

Comparison of models for yield prediction:

Comparison of zoning methods:

Yield maps and feedback. A combine with GPS and mass flow sensor builds a real-time yield map. Flow sensor calibration gives accuracy ±3–5%. Data cleaning: remove edge effects (turns), discard speeds <3 and >12 km/h. Apply kriging to smooth noise. Closed loop: The yield map is compared with the prescription map — we analyze which zones performed worse and adjust the model for the next season.

Integration into farming operations. The system connects to equipment telematics (John Deere Operations Center, CLAAS telematics), farm accounting (1С:Агропромышленный комплекс), and weather API services (Meteomatics, WeatherAPI).

Implementation process

1. Field audit and data collection. Analyze available satellite imagery, soil maps, yield history. Identify data sources (weather station, drones, equipment sensors).
2. System design. Choose model architecture, vector database (currently pgvector for embeddings), configure processing pipelines (Airflow).
3. Model development and calibration. Train zoning, prediction, and CV models on farm data. Validate against previous year data.
4. Integration with onboard computers. Set up export of prescription maps in ISOXML format for John Deere, CLAAS compatibility.
5. Testing and pilot. Run on one field for a season, adjust models based on actual yield.
6. Deployment and scaling. Roll out to all fields of the farm. Deliver dashboards and train agronomists.
