Although the chicken manure was easy to obtain and low cost to purchase, it cause the environment when fertilizing it a long period of time, for example, breeding mosquito, odor, water pollution and soil acidification... Organic farming has received more and more attention from environmentalists, academic, and consumers in recent years. This study used the fresh chicken manure for the main materials, adding and mixing the different adjustment materials, such as sawdust, reflow bacterium and analyze the ferment mixture in physics, chemistry and the biological. Recording the variation of temperature, moisture content, pH, C/N, germination ratio and heavy metal to determine compost maturity and plants. In the variation of temperature, moisture content, pH, C/N and germination ratio, showed that the regulation above 57.8℃ high temperature with fresh chicken mix reflow bacterium compost for 16 days, the PH of all the compost was alkaline, moisture content are in compliance with the standard. Fresh chicken manure compost and rapid fermentation of chicken manure compost C / N are less than 20, in line with compost C / N standard, so applying these two composts to pot experiment. Rapid fermentation of chicken manure compost germination rate is less than 90% does not meet the standard germination rate. The study used two different kinds of soil is laterite and cultivation soil, applying of fertilizer are fresh chicken manure compost, rapid fermentation of chicken manure compost and commercial organic fertilizer, cultivated plants as Water Convolvulus, Rapeseed and Pak-choi. It is observed that plants grew better in laterite with 3 types of rapid fermentation compost. The reason is that the alkaline rapid fermentation compost neutralize the acidity of laterite in long term. On the other hand, fresh manure compost worked better in cultivation soil in fostering plant growth. It is probably due to the abundant nutrients provided by the fresh manure compost.
