Satellite imagery has revolutionized agriculture by providing farmers with detailed, real-time data on crop health. During the middle and late growing seasons, this technology becomes crucial for monitoring crop growth and identifying deficiencies that may impact yields. By leveraging satellite imagery, farmers can take proactive steps to ensure their crops thrive, ultimately leading to better productivity and profitability.
How does satellite imagery work?
Satellite imagery works by capturing light across different bands, or specific wavelength ranges. These sensors measure electromagnetic radiation (EMR) reflected or emitted from Earth's surface. Different types of ground cover—such as vegetation, water, snow, and bare soil—absorb and reflect varying amounts of light along the spectrum. By analyzing this light, we can identify and isolate specific features and conditions on the ground. This capability is crucial for property analysis, as it allows us to remotely monitor and understand various aspects of land health and usage. For instance, vegetation reflects more near-infrared light and absorbs more red light, which helps distinguish it from other surfaces.
How Satellite Imagery Can Help Farmers Operate More Efficiently
Early Detection of Crop Stress
Satellite imagery allows farmers to detect areas of crop stress early in the growing season. By identifying issues such as nutrient deficiencies, water stress, or pest infestations, farmers can address these problems before they significantly impact crop yields.
Efficient Resource Management
With satellite imagery, farmers can pinpoint the exact locations that require intervention. This targeted approach helps in the efficient use of resources like water, fertilizers, and pesticides, reducing costs and environmental impact.
Monitoring Crop Growth
Throughout the growing season, satellite imagery provides continuous updates on crop growth. Farmers can track the progress of their crops, ensuring they are developing as expected and making timely adjustments as needed.
Historical Data Analysis
Satellite imagery also offers historical data, allowing farmers to compare current crop conditions with previous seasons. This comparison helps in understanding long-term trends and making informed decisions for future planting and management practices.

Mid-Growing Season
During this period, farmers can use satellite imagery to monitor the overall health of their crops. By identifying areas with poor growth or abnormal patterns, farmers can investigate the underlying causes and take corrective actions. For example, if certain areas show signs of water stress, irrigation can be adjusted accordingly.
Late Growing Season
As the crops approach maturity, satellite imagery helps in assessing the uniformity of crop development. Farmers can identify any late-season issues that might affect harvest quality and take steps to mitigate them. Additionally, imagery can aid in planning the harvest by highlighting areas that are ready for harvesting.
How to Access Satellite Imagery
Accessing satellite imagery has become increasingly easy with platforms like AcreValue. Farmers can generate detailed vegetation maps for their properties by following these steps:
- Select a property or property sale record on the AcreValue map.
- Generate a full property report.
- Navigate to the "Vegetation" tab within the report.
- Choose the desired image bands and date ranges to view historical and current vegetation data.
