The impact of typhoon and heavy rain has caused earth and rock after the collapse flowed into the reservoir, decreasing the effective capacity of reservoir siltation year by year. To ensure the effective capacity of the reservoir, dredging is the only method. However, the resulted silt stacking and disposal are major problems. Due to the aging of rural population in Taiwan, the method of dealing with 1.37 million tons of straw per year straw is to burn directly on the spot. This method will cause environmental pollution and also affect the microorganisms in the soil, resulting in a problem of reduced yield. With the pursuit of food safety in Taiwan, organic products have received attention. The Council of Agriculture promotes sustainable agricultural development and encourages farmers to use organic fertilizers to promote the use of “microbial fertilizers”. In order to solve the problem of silt and straw, in this study, we combine silt and straw with microbial fertilizer (probiotics), plant with sludge-to-straw ratio of 8 to 2 and 9 to 1 on planting the crop as Fushan lettuce, and observe its growth situation. It has been found through experiments that pure sludge and improved sludge can be used on planting and grow as much as ordinary soil. When the ratio of sludge to (straw + soybean meal + probiotic B) is 8:2, for 30 days growth intensity, the weight reaches 243.5g; for 40 days growth intensity, the weight reaches 462.6g. The results are in line with the economic harvesting weight. It can be seen that the improved sludge growth is not lower than that of the general soil, and the pure sludge is similar to the growth of the general soil.
