Evaluation of some physical properties of cattle manure

Cattle manure, which is obtained from cattles and is a biological material, goes through many basic processes such as collection from animal shelters, transportation, storage and distribution as animal fertilizer. The physical properties of manure are of great importance in the manure processes and the design of farm manure machinery. In this study, animal manure with and without bedding was considered as material. Manure bedding was selected from sawdust and straw. Among the characteristics effective in the mechanization of the applications; dry matter ratio, volumetric weight and natural repose angle were determined. As a result, it was determined that the type of bedding used, manure moisture content and repose angle were effective on the physical properties of manure. In addition, it was found that the dry matter ratio of farm manure changed with the type of bedding used and the dry matter content of straw-based manure was higher. When the volumetric weights were examined, the average volumetric weight of the manure without bedding was 857.48 kg/m³, the sawdust manure was 653.84 kg/m³ and the straw manure was 590.37 kg/m³. Moreover, it was obtained that the angle of repose values was lower in the bedding manure.
