Estimating weed dry matter within a wheat crop using total green cover measurements



Estimating weed dry matter within a wheat crop using total green cover measurements



Proceedings of the 7th International Conference on Precision Agriculture and Other Precision Resources Management, Hyatt Regency, Minneapolis, MN, USA, 25-28 July, 2004: 296-309



A portable dual-camera video system was used to evaluate the potential of using total projected green cover as an indirect measure of weed infestations in a wheat crop during early growth stages. The video system would have applications in mapping weed infestations to assist precision farming operations. The two cameras provided a real-time composite image of reflected light measured in red (640 nm), and near-infrared (860 nm) wavelengths.
