The GreenSeeker Hand Held Data Collection and Mapping Unit is a crop research and consulting tool that provides useful data to determine Normalized Difference Vegetative Index (NDVI) and Red to Near Infrared Ratios. These data points can be used in conjunction with other agronomic references to index basic nutrient response, crop condition, yield potential, stress, pest and disease impact in a quantitative objective manner. The unit can be used to monitor changing field (crop, plant) conditions during the growing season and/or the effects of different levels of an input compared to a local standard.

The GreenSeeker TR100 data collection and mapping systems allow you to map the plant health and vigour measurements while doing another job. No longer do you have to depend upon cloud free days for satellite images, or pay the high cost of aerial images. You can collect NDVI (Normalized Difference Vegetative Index) data when you need it. You can also collect data during existing farming operations such as spraying, cultivation, mowing, etc. These images can by used to create management zones, identifying pest and disease problems, evaluation of drainage systems efficacy, modifying soil sampling strategies, monitoring and modifying irrigation schedules, determine optimum harvesting dates, making variable rate prescription maps, etc.

The GreenSeeker® RT200 real time integrated optical sensing and application system measures crop status and variably applies the crop's nitrogen requirements. It predicts yield potential for the crop using the agronomic vegetative index NDVI. The nitrogen recommendation is based on in-season yield potential and the responsiveness of the crop to additional nitrogen.

Numerous NDVI readings are averaged across each zone. A prescription is written. The controller modifies the rate for each ensuing zone. The RT200 works with most variable rate controllers and delivery systems.
