  • Improved Yields: Timely intervention leads to a 15% increase in overall yield.

Precision Irrigation

Case Study: Vegetation Management 

Situation: A vegetation farm struggles with varying water needs across its plots.

Application: Soil moisture maps derived from satellite imagery provide detailed information on soil water content.

Impact:

  • Optimal Irrigation Scheduling: Farmers adjust irrigation schedules based on soil moisture levels.
  • Water Savings: Water usage is reduced by 20%, while vegetation quality and yield improve.

Pest and Disease Management

Case Study: Fodder Farming 

Situation: Fodder farms face frequent pest infestations, affecting crop yields.

Application: Satellite imagery analytics detect early signs of pest infestations by analyzing changes in crop color and health.

Impact:

  • Early Intervention: Farmers apply pesticides early, preventing widespread damage.
  • Reduced Pesticide Use: Targeted pesticide application lowers chemical use by 30%.
  • Higher Yields: The farms report a 10% increase in yield due to better pest management.

Yield Prediction and Planning

Case Study: Potato Farming

Situation: A potato farmer needs accurate yield predictions to plan harvest and sales.

Application: Satellite imagery combined with growth stage analysis provides accurate yield forecasts.

Impact:

  • Efficient Harvest Planning: The farmer optimizes harvest schedules based on predicted yields.

Impact:

  • Sustainability: The farms assure sustainable production.
  • Environmental Benefits: The farms reduce their environmental footprint, contributing to local biodiversity conservation.

Technical Details

The 4EI platform utilizes high-resolution imagery from leading satellite providers. By employing advanced machine learning algorithms and cloud-based processing, we deliver precise and timely insights. 

Satellite imagery analytics in agriculture rely on various types of satellites, each offering unique capabilities tailored to different analytical needs. Some of the primary satellite types used include:

Multispectral Satellites

Sentinel-2: Part of the European Space Agency’s Copernicus program, Sentinel-2 satellites provide multispectral imagery at resolutions ranging from 10 to 60 meters. They are applied for vegetation monitoring and land cover classification.

Landsat: Operated by NASA and the US Geological Survey, Landsat satellites offer multispectral imagery with 30-meter resolution, useful for long-term agricultural monitoring and analysis.

Airbus/Onyx: A series of high-resolution commercial satellites that provide imagery at sub-meter resolutions, suitable for detailed crop analysis and precision agriculture.

Radar Satellites

Sentinel-1: Also part of the Copernicus program, Sentinel-1 satellites use Synthetic Aperture Radar (SAR) to capture high-resolution images regardless of weather conditions or daylight. This is particularly useful for soil moisture estimation and monitoring crop growth under cloudy conditions.

Hyperspectral Satellites

EnMAP (Environmental Mapping and Analysis Program): This German satellite provides hyperspectral imagery, capturing data across a wide range of wavelengths. Hyperspectral data allows for detailed analysis of plant health, soil properties, and nutrient content.
