Abstract
This study focused on the characteristics of manure in five beef cattle farms and two breeding farms in Hanwoo centered in Gyeongsangbuk-do province. The results of analysis and evaluation are as follows; First, the pH of manure in all the farms in this study was within the appropriate range of 8.81 to 9.45. Second, the dry matter content varied from 44.7% to 70.5% for all the farms. Third, the total nitrogen content in all the farms was 2.05-3.04%, which is higher than the reported range; however, it could play a role as a soil improvement agent when used as compost. Fourth, although the exact range of ammonia-N (VBN) content was not reported, results analyzed in all the farms showed that the level of impact on the environment was insignificant. In conclusion, soil and environment improvement effects are expected to be effective if the manure at Hanwoo farms in the Gyeongbuk area are used as compost through appropriate management.
