FieldScout GreenIndex+ - Nitrogen App and Board - Product Manual

This manual explains how to use the GreenIndex+ as a tool for managing the nitrogen needs of your crop and overall plant health. 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.
