Soil reflectance is a cumulative attribute determined by interactions between light (photons) and the physical, chemical, biological properties of soil. such as organic matter, moisture, mineral oxide contents, soil texture, surface roughness all influence at unique wavelengths. Many standard sample preparation techniques are designed to alter properties, so homogenize samples improve consistency data collected. This study aims quantify effects one activity, drying, repeated wetting–drying cycles on visible–near-infrared reflectance, collecting from nine which were dried then wetted for total three times. demonstrates major, permanent drying wetting cycle presents model can be used correct these effects. These results have direct implications remote sensing activities, libraries, spectral libraries. show that without correction, collected stored samples, transferred studies, limited utility characterizing soils they exist in field. lab requires correction before it may predict field, handling procedures change intrinsic introduce systematic error into data.
