Abstract
Canopy reflectance patterns were determined for 2 fields each of wheat, sorghum and soyabeans. Results indicated that the reflectance ratio of the 545- to 655-nm wavelengths gave information on crop growth and might also be useful for indicating percentage cover. The reflectance ratio was < 1 early and late in the growing season, was about 1.3 for the mature crop and about 0.8 for bare soil. It tended to remain >1 during maximum growth then decrease towards maturity. For all crops studied the ratio closely followed crop growth and development and appeared to be more desirable than the near-infrared reflectance as an index of growth. The reflectance ratio alone did not appear to discriminate between crop species but it was thought that unique reflectance patterns might be an aid in crop species identification by means of remote sensing
