In the article we research application of culmiferous waste products of in the capacity of fractionated culmiferous litter on poultry plants at the low-ground content animal. For definition of optimal parameters of processing the initial culmiferous material exposed machining by a microwave radiation and was researched on micro and nano level for revealing qualitative changes of a structural surface.

Keywords: culmiferous bedding, microwave radiation, structural surface, the energy of the microwaves, capillary condensation, "pin" structure, scanning probe microscope.
