Sheep manure is an important byproduct of sheep farming. In the Bjelovar-Bilogora County (BBŽ), more than 10% of the total number of sheep registered in Croatia are raised. The aim of this paper was to determine the quality of sheep manure in the BBŽ area and the possibilities for its use. The quality of the manure was determined based on the results of laboratory analyses of samples collected during 2022 and 2023 from sheep farms in the BBŽ area. The samples revealed average values of dry matter, moisture, pH, organic carbon, nitrogen, phosphorus, and potassium. The research results indicate significant variations in the quality of manure depending on the year and season of sample collection. A statistically significant effect of the year on the dry matter and organic carbon content was found. The average dry matter content varied significantly between sampling seasons. The pH values remained relatively stable between sampling seasons. The most variable components were phosphorus and potassium, while nitrogen and organic carbon were the least variable. The variability suggests an inconsistent quality of the samples tested. The analyzed samples, due to their significant dry matter content and stable pH values, indicate a high potential for sheep manure as an organic fertilizer for application on various soil types. In addition to its use as organic fertilizer, sheep manure can also be used in biogas production.
