Upon the completion in comparison with stock farming defined in Water Pollution Control Act, and licensed for livestock farm or livestock and poultry feeding registration certificate for rivers and drainage ditch areas (including Peikang River drainage basin, Hsinfuwei River drainage basin, Jhoushuei River drainage basin, Tayilun drainage ditch, Pachiaoting drainage ditch, Shutsuoliao drainage ditch, Yutsailiao drainage ditch, Makungtsuo drainage ditch and Niutiaowan drainage ditch, etc.) in Yunlin County, stock farming pollution distribution map in Yunlin County is made in accordance with each geographical location. After 20 sessions of “Promotion and Propaganda Illustration Meeting for Water Pollution Law and the Application of Fermented Residues and Liquid” were held in all townships, 150 stock farmers were interviewed to check if they were willing to participate in using plan for farmland fertilizer constituents of fermented residues and liquid, in which more than half farmers showed willingness (accounting for 55.3%), and only 18.7% unwillingness. It’s obvious that most farmers acknowledged this policy substantially and positively contributes to stock farming. Regarding farmer questionnaire, more than 30% (higher than average) farmer respondents showed satisfaction and support towards each policy promotion; overall, it represented farmer respondents in Yunlin County were very satisfied with and supported promotional achievements, including the willingness as high as 3.68 points to participate in the policy of farmland irrigation with fermented residues and liquid, even higher than the average 3.51 points of policy support. It showed farmer respondents would like to take practical action to participate in irrigation policy, meaning the public affirmed the implementation of the irrigation policy for farmland fertilizer constituents. There’re total 6 projects applicable to reduction strategies for greenhouse gases collected from the present international reduction strategies and goals for greenhouse gases and Clean Development Mechanism (CDM), as well as from assistance object, condition, project and subsidies key points listed in Subsidies Operation Guideline for the Promotion Planning of Methane Gas Generating System of Bureau of Energy, Ministry of Economic Affairs. Far East University was commissioned to carry out questionnaire for those farmers dealt with farmland use of fermented residues and liquid, with 509 valid questionnaires completed. As a whole, more than 30% (3 points is an average in five-point scale) farmer respondents showed satisfaction and support towards each policy promotion, representing farmer respondents in Yunlin County were very satisfied with and supported promotional results, in which the willingness to participate in the policy of farmland irrigation with fermented residues and liquid was even up to 3.68 points, higher than the average 3.51 points of policy support. It showed farmer respondents were willing to take practical action to participate in irrigation policy Total harvest area for various crops in Yunlin County was surveyed to evaluate using potential for farmland fertilizer constituents of fermented residues and liquid. The results showed that the crop harvest areas in Yunlin County could bear the use of the whole county’s livestock manure; however, delivery problem remained unsettled on effective use as a precondition. Farmland fertilizer constituents of fermented residues and liquid successfully used for pre-/post-irrigation in 8 cases to make comparison between soil, groundwater and river pollution was found no adverse effects on soil and groundwater, and little improvement on water body and water quality in the rivers around. Assistance object, condition, project and subsidies key points listed in Subsidies Operation Guideline for the Promotion Planning of Methane Gas Generating System of Bureau of Energy, Ministry of Economic Affairs, including subsidy plan, letter of intent, application form agreed to the filing of renewal energy generating equipment were collected aiming at a certain size of stock farms feeding more than 5,000 livestock inside the county to complete the investigation. Subject to the consideration of the previous implementation experiences, regional co-investment and effectiveness, most farmers have less willingness or are holding back to see what happens next, obviously, the best incentive for farmer to get involved is nothing but increase key factors such as wholesale buying rate, power generating benefit and field devices in the aspect of implementation. Regarding inspection of fermented residues and liquid, total nitrogen concentration of mixed liquor is about 0.88~19.92 times of supernatant. On the premise of initially planned land demand in the future, irrigation with supernatant can effectively decrease land demand; on the premise of heavy metal residues, heavy metal copper concentration of mixed liquor is higher than supernatant and heavy metal zinc concentration of mixed liquor is higher than supernatant, irrigation with supernatant can reduce the risk of copper and zinc contamination to the land. Under the current laws and standards, each stock farm can bear irrigation amount range 139,784 ton/ha (Yuchun Stock Farm) ~17,594,286 ton/ha (Sanyuan Stock Farm) (mini value of copper and zinc irrigation amount in each farm) of fermented residues and liquid; 69,892 ton /ha~8,797,143 ton/ha is given as 50% safe irrigation amount. Therefore, the results showed that heavy metal in the short term will not have a large number of remaining fermented residues and liquid left in the soil according to the current irrigation amount. In response to the survey for farmland fertilizer constituents of fermented residues and liquid, apart from Taiwan’s Soil and Groundwater Pollution Remediation Act, control standards, sampling and analysis methods, a professional team composed of domestic specialists and scholars in professional fields can provide professional advice for various aspects of water pollution, policies and regulations, soil and groundwater pollution and agriculture in the first year of policy implementation to effectively accelerate review procedure of the plan. Detection of fermented residues and liquid, soil and groundwater in 14 stock farms and written using plan for farmland fertilizer constituents of fermented residues and liquid were completed the review procedure upon submitting to Agriculture Department, 8 farms of which have successfully been reviewed to obtain irrigation permit. There’re 61,774 pigs and 1,100 cattle raised in these 14 stock farms, accounting for 4.26% of total pigs and 3.74% of cattle raised in the county, and total irrigation area is up to 93.0147 hectares.
