Laboratory determination of reflectance coefficient selected for the bedding materials related to the properties of the light sourced used in the barns

Original language description

"The objective of this paper was determination of the reflectance coefficient of selected materials that can be used as bedding in barns for farm animals (partially dehydrated digestate from BGS and the same partially dehydrated digestate with the addition of calcium hydroxide (hydrated lime in the form of powder) in the amounts 0.25, 0.125 and 0.0625 kg per 1 kg of partially dehydrated digestate) depending on the optical properties of the light sources used in barns (mainly in particular linear fluorescent lights) and dampness of these materials. We compare the spectra of impacting and reflected light including their energy. We ascertained that with the increasing dampness of the bedding material, a small but varying shift in wavelengths of the spectrum of the reflected light towards higher values occurred for all materials. At the same time, also the value of the colour temperature of the reflected light changed. The impacting and also reflected light and their spectra were measured by the radiometer with 0.5 nm resolution. Measuring was executed in the measuring device and repeated for each selected bedding material and each light source. All results were statistically processed by nonparametrical methods due to small sets of the measured data."
