Spectral Reflectance of Wheat Residue during Decomposition and Remotely Sensed Estimates of Residue Cover
Remotely sensed estimates of crop residue cover (fR) are required to assess the extent of conservation tillage over large areas; the impact of decay processes on estimates of residue cover is unknown. Changes in wheat straw composition and spectral reflectance were measured during the decay process and their impact on estimates of fR were assessed. Proportions of cellulose and hemicellulose dec...
متن کاملAssessing crop residue cover using shortwave infrared reflectance
Management of crop residues is an important consideration for reducing soil erosion and increasing soil organic carbon. Current methods of measuring residue cover are inadequate for characterizing the spatial variability of residue cover over large fields. The objectives of this research were to determine the spectral reflectance of crop residues and soils and to assess the limits of discrimina...
متن کاملEstimates of Corn Residue Quality
Two experiments were conducted to evaluate the effects of corn residue harvest method on animal performance and diet digestibility. Experiment 1 was designed as a 2 x 2 + 1 factorial arrangement of treatments using 60 individually fed crossbred steers (initial BW = 283; SD = 32 kg; n = 12). Factors were corn residue harvest method (highstem and conventional) and supplemental RUP at 2 concentrat...
متن کاملConstruction of synthetic spectral reflectance of remotely sensed imagery for planning purposes
Urban and environment development plans commonly lack spectrally based value-added information layers such as expected albedo, emissivity and temperature of the planned landscapes. These can be integrated into plans in order to assist in using specific materials or in the way new landscapes and urban spaces are designed. In contrast to existing space-borne remotely sensed imagery from which inf...
متن کاملEblup Estimates by Using Remotely Sensed Data
The knowledge of auxiliary variables for entire population is a necessary task in many agricultural applications; for example a method widely applied to improve the efficiency of crop area estimations is the regression estimator (Cochran, 1977), that exploit the correlation between classified satellite images (auxiliary information) and ground surveys’ data. The regression analysis offer a lot ...
