The Power of Your SmartPhone...for Nitrogen Management!
• Collect In-Season Data From Your Crop Via Image Analysis
• Make Site-Specific Fertilization Decisions
*Download the FieldScout GreenIndex+ application from the Apple iTunes Store ($99.00), the link will be provided here. In order for the Application to be used properly, you must purchase the FieldScout GreenIndex+ Board (Item 2910B) here.
Now there is a better, more affordable way to manage the nitrogen needs of your crop. The FieldScout GreenIndex+ App captures and processes images from an iPhone, iPod Touch, or iPad and instantly computes the DGCI (Dark Green Color Index) of your leaves. Our GreenIndex+ technology is sensitive to low nitrogen levels in the leaves. DGCI has been correlated to SPAD readings in corn at the V6 growth stage**. This computed SPAD index is displayed by GreenIndex+. Nitrogen uptake increases dramatically at the beginning of the V6 development stage. Corrective measures, based on early diagnosis of severe nitrogen deficiencies, can prevent yield reduction.
Digital images taken in the field typically exhibit variation due to ambient lighting, shadows and texture. Green and yellow reference standards on a pink background provide contrast and aid the imaging processing software. This allows for images to be captured under a broad range of lighting conditions.
FieldScout GreenIndex+ offers digital image analysis of leaves, providing growers with an accurate, low-cost method for managing in-season fertility and helps you deliver improved yield, lower nitrogen costs, and increased profits. All data is logged and geo-referenced, and can be emailed to your PC for further analysis.
Patent pending. iOS Device not included. Android version coming soon.
