Today, a desirable way to manage livestock manure is to activate its utilization as a resource. The production of high quality liquid fertilizer of livestock manure is very important because it increases the use of various liquid fertilizer. However, the result of mature evaluation with a maturity measuring instrument for liquid fertilizer showed that the deviation of concentration between liquid fertilizer did not bring into uniformity. The result is also making sure that quality management for liquid fertilizer is not smoothly made. Quality evaluation for compost and liquid fertilizer includes physical, biological, chemical and microbiological methods, but a chemical method is mainly being implemented due to fairness and field application. Therefore, this study figured out correlation in feces and urine through regression analysis of livestock manure and tried to create a research plan to carry out efficient quality analysis of managing livestock manure.
The main purpose of this study is to collect basal data on livestock manure management condition to establish reasonable direction of Korean LFQC(Liquid Fertilizer Quality Certification) system. We investigated relevant laws and regulations on livestock manure fertilizer, certifications of eco-friendly agricultural products, government policies on livestock manure management and some field case studies on liquid manure treatment system in pig houses. From the case studies, we classified all kinds of swine manure management systems into six stages of bio-physical treatment process; stage1. simple piggery slurry management, stage2. solid-liquid separation, stage3. liquid fertilizer aeration, stage4. fermented liquid fertilizer to recirculation, stage5. stabilized liquid fertilizer, and stage6. marketable liquid fertilizer for crops and vegetables. As a result from this study, the liquid fertilizers in ' LFQC' system could be classified as three levels according to the usage patterns in field; 1st. individual farm level(IFL), 2nd. joint farm level(JFL), and 3rd. commercial level(CML). And finally, we found some characteristics in ' main level-grading factors of liquid fertilizer' such as fertilizing value, harmfulness, stability, uniformity, economic effect, storage potential, stability, functionality were required to the establishment of ‘LFQC’ system. More research on ' evaluation standards' for concrete guideline and on the ' main level-grading factors' be needed to complete Korean ‘LFQC’ system.
Establishment of a new concept of environmental friendly livestock manure management is required based on the facts. But now liquid fertilizer quality in korea shows a large difference among regions and the regulations are uncertain. Focusing on precedent study on main level-grading factors of liquid fertilizer quality certification, the study collected laws and standards related to liquid fertilizer of livestock manure at home and abroad and produced evaluation standards. Liquid fertilizer was divided into four factors (fertilizing value, harmfulness, stability and uniformity). According to each item, scores were awarded based on 16 details: fertilizing value (Nitrogen concentration, the whole concentration of Nitrogen, Phosphoric acid and Kalium), harmfulness (heavy metals, pathogenic microorganism and antibiotics), stability (maturity degree and odour), uniformity (EC, BOD, SS, moisture content and salt). The grade of liquid fertilizer, A (42~48), B(34~41), C (26~33) were rated using total scores.
