A tethered helium balloon was used to position two digital cameras and a mini video camera above a fertiliser trial plot where wheat (Tritcum spp L.) was being grown. The plot was a long-term fertiliser trial area where nitrogen application rates varied between 0-120 units of N at 40 unit increments. Colour and near-infrared images were acquired that captured the whole 3ha plot. These images were interrogated and a high correlation was found between the image and yield (R2 = 0.91) and a moderate correlation between image and protein (R2 = 0.66).
