This study was conducted to investigate the status and strategy of swine manure utilization as a fertilizer of 109 swine farms in the Gyeongnam, Korea.
The characteristics of swine farm management, personal properties of owner, types of swine buildings, facilities and equipment for manure management, conditions for manure recycling, the farming for recycled resources using livestock manure were surveyed and analyzed.
The results obtained are as follows;
1. Age of farm owners were occupied as 44.1% for 50s followed by the 60s with one-forth and 40s with 22.9%. Educational background of farm owners, a high school graduate makes up the largest proportion of farm owners followed by a college graduation with 35.8%.
2. The manure collection method of swine farms were occupied as 34.9% with totally slurry system and more than 50% slurry system with 34.9% of farms. However, swine farms with scraper system more than 50% were occupied as 11%. Swine manure management of the farm by ocean dump were occupied as more than two-third, but recycling more than 50% were occupied as only a 8.3%.
3. The manure management cost per manure ton were occupied as more than two-third with 10,000won~15,000won. The cost will pay for manure management, 10,000won~15,000won per ton makes up the largest proportion of farm owners. Separator, loader and vehicle to collection, transportation of liquid manure were occupied as 72.5%, 44% and 10.1%, respectively.
4. Many of swine farm owners know well or have some knowledge of the ban of livestock manure ocean dump, but 22% of farm owners don't know that. Fifty seven percent of swine farm owners replied that will take the recycling system inclusion the cooperative recycling. But eight percent of swine farm owners replied that will out of business after ban of ocean dump of livestock manure.
5. Recognition of the farming for recycling resources using livestock manure were occupied as 37.6%, however, 25.8% of swine farm owners don't know that. More than sixty percent of swine farms will take the recycling system according to the farming for recycling resources using livestock manure.
Conclusively, we have a suggestion in order to promotion of the farming for recycling resources using livestock manure in the Gyeongnam with increasing the portion of recycling of swine manure in each county and revitalizing the marketing of the liquid and solid swine manure fertilizers.
