Fig. 2. Spectral response curves for conventional (CT) and strip tillage (ST) treatments at the Coastal Plain study site. Data represent average reflectance (%) along the y axis and wavelength (485–1650 nm) along the x axis for remotely sensed data acquisitions on 24 May, 8 June, and 16 June 2004. Significant treatment differences for each wavelength are denoted (*) ( = 0.10).
