Yara ImageIT is a farming app designed to measure nitrogen uptake in a crop and generate a nitrogen recommendation based on photographs of the crop.
Besides showing the user how much nitrogen to apply to obtain optimal yield and crop quality, ImageIT provides quality assured fertilizer recommendations with Yara preferred product and contact information of the closest Yara office.
The app turns a farmer’s smartphone camera into a high-tech crop nutrient tester. ImageIT calculates nitrogen uptake based on leaf cover, leaf green color and estimated fraction of brown leaves. The technology behind the application is a comprehensive image analysis that classifies leaf pixels, filters noisy areas and counts leaf pixels. Despite being an advanced agricultural tool ImageIT is user-friendly and flexible in terms of technical requirements. The app is largely insensitive to camera type and works with low resolution images with a file size as small as 50 – 200 KB.
In poor signal areas ImageIT can store images offline to enable photo capture with no network access, and send the photographs for interpretation when the smartphone reaches a wifi or 3G zone.
